TIMer-reLATeD TerMInOLOGy
• what is a timer?
The timer is a relay having such an
output (with or without contact) which
electrically closes (turns ON) or opens
(turns OFF) the circuit after a preset time
elapses when electrical or mechanical
input is given.
• On-delay Operation (Time delay
operation)
The on-delay operation is an operation
to give output when preset time expires
after a predetermined input is given to
the power supply circuit or input circuit.
On-delay operation includes power supply on-delay operation and signal ondelay operation.
Example of power supply on-delay operation
OFF

• Off-delay Operation (Time delay
resetting)
The off-delay operation is an operation
to turn OFF output when preset time
expires after a predetermined input
is given to the power supply circuit or
input circuit, and at the same time output signal is given and predetermined
input is turned OFF. Off-delay operation
includes power supply off-delay operation and signal off-delay operation.

• Flicker Operation
The flicker operation is an operation to
repeat output ON/OFF action according to preset ON time and OFF time
while a predetermined input is given to
the power supply circuit or input circuit.
Flicker operation includes OFF-start
flicker operation and ON-start flicker
operation.

• Operating Time
The operating time means the time which
elapses between the addition of predetermined input to the power supply circuit
and input circuit and the completion of
operation for preset time.
• Hold Time
It means the time which elapses between
the completion of operation for preset
time and the start of resetting.
• Pause Time
It means the time elapses between the
start of operation for preset time and
the addition of input required again for
the power supply circuit or input circuit.
Timer does not perform normal function
unless this pause time is set longer than
the timer reset time.
• resetting
It means that the operation returns to
the state before starting while the timer
is in operation for preset time or after it
completes the operation for preset time.
Resetting during the operation for preset
time is referred to as halfway resetting.
OFF

• Preset Time
The preset time is the control time set by
setting time-variable timer.

• Star ( )/Delta (g) Operation
T h i s operation controls the time in
the star connection used for star-delta
starting which is conducted for starting
a cage induction motor and the time for
switching the star connection over to
delta connection.
• reset Time
It means the time elapses between shutoff of input to the power supply circuit or
input of reset signal and the completion
of resetting.
Timer resetting function shares the reset
of contact, reset of mechanical parts
such as pointer etc., reset of parts in
internal circuit such as capacitor etc.,
and the value at which all of these parts
complete their resetting operation is
regarded as reset time. If timer is used
for a pause time shorter than specified
reset time, the operation time expires
earlier than preset, unexpected instantaneous operation takes place or the
operation is failed, thus making it impos-

• Minimum Power Application Time
It means the minimum time during which
power must be supplied in order to operate timer normally, in the case of power
supply off-delay timer.
• Fluctuation of Operating Time
It means the irregularity in operating time
caused when timer is set at specified
time and the operation is repeated under
the same conditions. It is also referred
to as repetitive error.
• voltage error
It means the difference between the
operating time at the rated voltage and
that within the allowable voltage range.
• Temperature error
It means the difference between the
operating time at the temperature of
20±2°C and that within the allowable
temperature range.
• Set error
It means the difference between the set
time and the time which actually elapses.
It is also referred to as setting error.
The set error of an analog timer is the
rate to the full-scale value. If the set error
is ±5%, it becomes equivalent to an error
of maximum ±5 hours on the assumption that 100 hours is set in the range of
100 hours. The error produced when 10
hours is set is also equivalent to an error
of maximum ±5 hours. As far as the set
error is concerned, digital timer is by far
exact. Select a digital timer for the case
when accuracy is required.
When using an analog type multi-range
timer for setting of long time, the setting
procedure stated as follows minimizes
the error. For example, if you want to set
8 hours in the range of 10 hours, first set
the pointer to such a graduation where
the actual operating time should become
as close to 8 seconds as possible in the
range of 10 seconds. Then, reset the
range to 10 hours, leaving the pointer set
at the graduation as it is.
• Pause Time error
It means the difference between the operating time to a fixed pause time and the operating time to a pause time that varies.
The pause time characteristics are the main characteristics of CR timer (timer exploiting charge and discharge of capacitor C and
resistance R).
If the oscillation count timer (timer which comprises an oscillation circuit composed of CR and quartz and is operated by a counting
circuit inside IC or micro-computer which counts the reference signal) is used, the pause time error becomes almost negligible owing
to its principles of operation. Accordingly, the description about these characteristics may be omitted for the oscillation count timer.
• equation for each error and Measurement Conditions
The operation time shall be measured, in principle, for retention time of 0.5 second and halt time of 1 second.
The measurement shall be repeated five times except for the initial test. The equation for each error and the measurement conditions are shown in the table below:

• Functional vibration resistance
Means such a vibration as occurs in the
range where the contact closed with
that vibration during the use of the timer
remains closed for the specified time (3
or 1 msec.) minimum.
• Destructive vibration resistance
Means such a vibration as occurs in the
range where no part is damage with that
vibration during the transportation or use
of the timer and the operation characteristics are maintained.
• Functional Shock resistance
Means such a shock as occurs in the
range where the contact closed with
that shock during the use of the timer
remains closed for the specified time
(1 ms) minimum.
• Destructive Shock resistance
Means such a shock as occurs in the
range where no part is damaged with
that shock during the transportation or
use of the timer and the operation characteristics are maintained.
• Mechanical life
Means the durability that is achieved
when the control output is performed in
the no-load state.
• electrical life
Means the durability that is achieved
when the specified voltage and current
loads are individually applied to the control output while being turned ON and
OFF. Generally, the life of the timer is
represented by the number of times the
control output is performed. When a
load is connected to the control output,
the term of „electrical life“ is used. When
no load is connected to the control output, the term of „mechanical life“ is used.
The electrical life is shorter than the
mechanical life, and becomes longer as
the load decreases. The life of the timer
is made longer by connecting a relay or
a similar part rather than directly switching a large load with the control output.
• rated power consumption
Means the power that is consumed when
the rated operation voltage is applied to
the power circuit.
(Rated power consumption = rated voltagexcurrent consumption)
• rated control capacity
Means the reference value that is used
to determine the performance of the
switching part of the load. This value is
represented by the combination of voltage and current.
• Contact resistance
Means the combined resistance that consists of the contact resistance between
contacts, and the conductor resistance of
pins and contact springs.
• Insulation resistance
Means the resistance between a contact
or a conductive pin like the pin to which
the operation voltage is applied, and
a dead pin or a non-conductive metallic part like the time case, the base,
or a retaining screw; or the resistance
between contacts.
• withstand voltage
Means the limit value that does not
cause breakdown when high voltage is
applied for one minute to the same location as measured for insulation resistance. The detectable leak current is normally 10 mA. In special cases, however,
it may be 1mA or 3 mA.
• withstand surge voltage
Means the limit value that shows the
durability against momentary abnormal voltage resulting from lightning or
switching a conductive load. The surge
waveform is represented by the standard
impulsive voltage waveform at ±(1.2x50)
µs or ±(1x40) µs.

Cautions for circuits
1. Protective circuit for timer contact
In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting
from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point.
Application
AC
DC
(see note.)
Available
r
c
Diode
Available
Available
If the load is a relay or solenoid, the release time lengthens.
Effective when connected to both contacts if the power supply voltage is
24 or 48 V and the voltage across the load is 100 to 200 V.
Features/Notes
Device Selection
If the load is a timer, leakage current
flows through the CR circuit causing
faulty operation.
—
Note: If used with AC voltage, be sure
the impedance of the load is sufficiently
smaller than that of the c and r.
As a guide in selecting r and c,
c: 0.5 to 1 mF per 1 A contact current
r: 0.5 to 1 W per 1 V contact voltage
Values vary depending on the properties of the load and variations in timer characteristics.
Capacitor c acts to suppress the discharge the moment the contacts open. Resistor r
acts to limit the current when the power is turned on the next time. Test to confirm.
Use a capacitor with a breakdown voltage of 200 to 300 V. Use AC type capacitors
(non-polarized) for AC circuits.
2. Type of Load and Inrush Current
The type of load and its inrush current
characteristics, together with the switching frequency are important factors which
cause contact welding. Particularly for
loads with inrush currents, measure the
steady state current and inrush current
and use a relay or magnet switch which
provides an ample margin of safety.
The table below shows the relationship
between typical loads and their inrush
currents.
Inrush current
Resistive load
Steady state current
Solenoid load
10 to 20 times the steady state current
Motor load
5 to 10 times the steady state current
Incandescent lamp load
10 to 15 times the steady state current
Mercury lamp load
1 to 3 times the steady state current
Sodium vapor lamp load
1 to 3 times the steady state current
Capacitive load
20 to 40 times the steady state current
Transformer load
5 to 15 times the steady state current
When you want large load and long life
of the timer, do not control the load direct
with a timer. When the timer is designed
to use a relay or a magnet switch, you
can acquire the longer life of the timer.
3. Connection of input
The PM4H and LT4H series use power
supply without a transformer (power and
input terminals are not insulated). In
connecting various kinds of input signals, therefore, use a power transformer
in which the primary side is separated
from the ungrounded secondary side as
shown in Fig. A, for the power supply for
a sensor and other input devices so that
short-circuiting can be prevented.
ZNR varistor
Not available
Available
The diode connected in parallel
causes the energy stored in the coil
to flow to the coil in the form of current and dissipates it as joule heat
at the resistance component of the
inductive load.
This circuit further delays the release
time compared to the CR circuit.
(2 to 5 times the release time listed in
the catalog)
Use a diode with a reverse breakdown voltage at least 10 times the
circuit voltage and a forward current at least as large as the load
current.
In electronic circuits where the
circuit voltages reverse breakdown
voltage of about 2 to 3 times the
power supply voltage.
Available
Available
Using the rated voltage characteristics of the varistor, this circuit
prevents excessively high voltages
from being applied across the
contacts. This circuit also slightly
delays the release time.

current flow
Do not use a single coil transformer (e.g.,
Sly-Duck). Otherwise, the internal circuit
of the timer will be short-circuited as
shown in Fig. B resulting in breakdown.
4. Long Continuous Current Flow
Long continuous current flow through
the timer (approx. one month or longer)
cause generation of heat internally,
which degrade the electronic parts. Use
the timer in combination with a relay
and avoid long continuous current flow
through the timer.
5. Leakage current
1) For connecting and disconnecting
operating voltage to the timer, a circuit
should be used, which will prevent the
flow of leakage current. For example, a
circuit for contact protection as shown
in Fig A. will permit leakage current flow
through R and C, causing erroneous
operation of the timer. Instead, the circuit shown in Fig. B should be used.

2) If the timer is directly switched with a
non-contact element, leak current may
flow into the timer and cause it to malfunction.
6. Power off time
If the operation voltage for the timer is
turned ON after the limit time operation
is completed or before the limit time
is reached, the Power off time longer
than the timer restoration time must be
secured.
7. Suicide circuit
If the timer is restored immediately after
the specified time is reached, the circuit
must be configured so that the restoration time of the timer can be secured
sufficiently.
If the power circuit for the timer is turned
OFF with the timer contact, a suicide
circuit may be configured (Fig. A). In
order to settle the problem with this
potential suicide circuit, the circuit must
be designed so that the timer is turned
OFF after the self-retention circuit is
completely released (Fig. B).
Cautions for use
(common for all models)
2) The following connection might result
in short circuit between the heteropolar
contacts in the timer.
Rectification type
Ripple percentage
Single-phase, full-wave
Approx. 48%
Three-phase, full-wave
Approx. 4%
Three-phase, half-wave
Approx. 17%
Note: Refer to the ripple percentage of each timer.
3) Make sure that no induced voltage
and residual voltage are applied between
the power pins on the timer after the
power switch is turned OFF.
(If the power line is wired in parallel with
the high-voltage and motor lines, induced
voltage may be produced between the
power pins.)
3. Control output
1) The load for the control output must
be used within the load capacity specified in the rated control capacity. If it is
used exceeding the rated value, the life
is greatly shortened.

8. electrical life
The electrical life varies depending on
the load type, the switching phase, and
the ambient atmosphere. In particular,
Bad example
the following cases require careful attention:
(1) If an AC load is switched in synchronized phases:
Locking or welding is liable to occur due
to contact transposition. Check this with
the actual system.
(2)If a load is switched very frequently:
If a load which generates arcs when a
contact is switched is turned ON and
OFF very frequently, nitrogen and oxygen in air are combined due to arc energy and then HNO3 is produced. This
may corrode metallic materials.
The effective countermeasures include:
1. Using an arc-extinguishing circuit;
2. Decreasing the switching frequency;
and
3. Decreasing the humidity in the ambient atmosphere.

1. Pin connections
Correctly connect the pins while seeing
the terminal layout/wiring diagram. In
particular, the DC type, which has polarities, does not operate with the polarities
connected reverse. Any incorrect connection can cause abnormal heating or
ignition.
2. Connection to operation power supply
1) Supply voltage must be applied at a
time through a switch, a relay, and other
parts. If the voltage is applied gradually, the specified time may be reached
regardless of its value or the power supply may not be reset.
2) The operation voltage for the DC type
must be at the specified ripple percentage or less. The average voltage must
fall within the allowable operation voltage
range.

4. Installing the timer
1) To install the timer, use the dedicated
pin bracket or socket (cap). Avoid connecting the pins on the timer by directly
soldering them.
2) In order to maintain the characteristics, do not remove the timer cover
(case).
5. Superimposed surge of power supply
For the superimposed surge of power
supply, the standard waveform
(±1.2x50µs or ±1x40µs) is taken as the
standard value for surge-proof voltage.
(The positive and negative voltages are
applied each three or five times between
the power pins.)
For the standard values for the PM4H,
LT4H and S1DX type timers, see the
respective items in „Cautions for use.“

If external surge occurs exceeding the
specified value, the internal circuit may

absorption element. The typical surge
absorption elements include a varistor, a capacitor, and a diode. If a surge
absorption element is used, use an oscilloscope to see whether or not the foreign
surge exceeding the specified value
appears.
6. Changing the set time
Do not change the set time when the
limit time operation is in progress.
However, this is possible only with the
motor-driven type timer if the set time
is shorter than the remaining time. For
changing the set time on the digital timer
(LT4H series), see the relevant item in
„Cautions for use.“
7. Operating environment
1) Use the timer within the ambient temperature range from –10°C to +50°C
+14°F to +122°F (+55°C +131°F for the
LT4H series) and at ambient humidity of
85% RH maximum.
2) Avoid using the timer in a location
where inflammable or corrosive gas is
generated, the timer is exposed to much
dust and other foreign matter water or oil
is splashed on the timer or vibrations or
shocks are given to the timer.
3) The timer cover (case), the knobs, and
the dials are made of polycarbonated
resin. Therefore, prevent the timer from
being exposed to organic solvents such
as methyl alcohol, benzine, and thinner,
strong acid substances such as caustic
soda, and ammonia and avoid using the
timer in atmosphere containing any of
those substances.
4) If the timer is used where noises are
emitted frequently, separate the input
signal elements (such as a sensor), the
wiring for the input signal line, and the
timer as far as possible from the noise
source and the high power line containing noises.
8. Checking the actual load
In order to increase the reliability in the
actual use, check the quality of the timer
in the actual usage.
9. Others
1) If the timer is used exceeding the
ratings (operation voltage and control
capacity), the contact life, or any other
specified limit, abnormal heat, smoke, or
ignition may occur.
2) If any malfunction of the timer is
likely to affect human life and properties,
give allowance to the rated values and
performance values. In addition, take
appropriate safety measures such as a
duplex circuit from the viewpoint of product liabilities.

• Changing the set time
1. It is possible to change the set
time with the up and down keys even
during time delay with the timer.
However, be aware of the following
points.
1) If the set time is changed to less than
the elapsed time with the time delay set
to the addition direction, time delay will
continue until the elapsed time reaches
full scale, returns to zero, and then
reaches the new set time. If the set time
is changed to a time above the elapsed
time, the time delay will continue until the
elapsed time reaches the new set time.
2) If the time delay is set to the subtraction direction, time delay will continue
until “0” regardless of the new set time.
2. If the set time is changed to “0,” the
unit will operate differently depending
on the operation mode.
1) If the operation mode is set to A
(power on delay 1) or A2 (power on
delay 2), the output will turn on when
the power supply is turned on. However,
the output will be off while reset is being
input.
2) In the other modes, the output turns
on when the start is input. When the
operation mode is C (signal off delay),
D (Pulse one shot), or F (Signal flicker),
only when the start input is on does the
output turn on. Also, when the reset is
being input, the output is off.
• Power failure memory
The eePrOM is used for power failure memory. It has a life of Min. 105 over-writings.
The eePrOM is overwriting with the following timing.
Output mode
Power ON delay (2) A2
Addition G
Other modes
Overwrite timing
When power is OFF
Change of preset value or start, reset input
When power is OFF after being ON

* Be aware that the contents of EEPROM for all modes will be overwritten when power is turned OFF during input to external lock terminals R to E and 7 to 6 .
Such an action does not exist by doing lock operation from the front.

Resets the elapsed time and the output
{ SET/LOCK switch
Changes over the display between T1/T2 settings, sets the operation
mode, checks the operation mode and locks the operation of each key
(such as up, down or reset key).
1) Setting or changing the operation mode
Ex: Setting operation mode display
(1) When the UP or DOWN key at the first digit is pressed with the SET/LOCK
(PULSE-A example)
switch pressed, the mode is changed over to the setting mode.
(2) Now release the SET/LOCK switch.
(3) The operation mode in the setting mode is changed over sequentially in the left or right direction by pressing the UP or DOWN key at the first digit, respectively.

(4) The operational mode displayed at present is set by pressing the RESET switch, and the display returns to the normal condition.
2) Setting (changing) the time
(1) Pressing the SET/LOCK key switches the set value display between T1 and T2. Display the timer (T1 or T2) which is to be set (or changed).
(2) After displaying the timer (T1 or T2) which is to be set, press the UP or DOWN key to change the time.
• Checking the operation mode
When the UP or DOWN key at the second digit is pressed with the SET/LOCK switch pressed, the operational mode can be checked.
The display returns to the normal condition after indicating the operational mode for about two seconds. (While the display indicates the operational mode for about two
seconds, the other indicators continue to operate normally.)
• Setting the lock
When the UP or DOWN key at the fourth digit is pressed with the SET/LOCK switch pressed, all keys on the unit are locked.
The timer does not accept any of UP, DOWN and RESET keys.
To release the lock setting, press the UP or DOWN key at the fourth digit again with the set/lock switch pressed.
* Operational mode, adding and subtracting and minimum input signal range cannot be set at T1 and T2, respectively.
• Changing over the T1/T2 setting display
The T1/T2 setting display is changed over by pressing the SET/LOCK switch. (This operation gives no effect on the other operations. The set time and elapsed time
(residual time) at T1 are linked with those at T2.)
• Changing the set time
1) It is possible to change the set time with the UP and DOWN keys even during time delay with the timer. However, be aware of the following points.
(1) If the set time is changed to less than the elapsed time with the time delay set to the addition direction, time delay will continue until the elapsed time reaches full
scale, returns to zero, and then reaches the new set time. If the set time is changed to a time above the elapsed time, the time delay will continue until the elapsed
time reaches the new set time.
(2) If the time delay is set to the subtraction direction, time delay will continue until “0” regardless of the new set time.
2) When the set times at T1 and T2 are set to 0, the output becomes ON only while the start input is carried out. However, while the reset input is carried out, the output
becomes OFF.
