■ Using the Setting Ring
Setting a Specific Time
Mount the Panel Cover on the Timer, set the desired time with the time setting knob, and place Time Setting Ring A onto the time setting knob so
that the time setting notch of Time Setting Ring A is in the center of the reset lock position of the Panel Cover.

Example: To set a range of 4 and 8 s.
Mount the Panel Cover on the Timer, set the time setting knob to 4 s (the lower limit of the setting range), and place Time Setting Ring C onto the
time setting knob so that the stopper of Time Setting Ring C is on the right edge of the reset lock position of the Panel cover. Next, set the time

Time Setting Ring/Panel Cover
There are two types of Panel Covers (Y92P-48GL and Y92P-48GB),
all of which are available in two colors. Use the most suitable type of
Panel Cover with the design of the scaling plate according to the
application.
When setting a given time for the Timer, use of the Y92S-27 or
Y92S-28 Time Setting Ring facilitates the time setting operation and
minimizes possible setting errors by operators.
The Time Setting Ring and Panel Cover should be used as a pair.

■ Basic Setting
Setting of Selectors
The selectors can be turned clockwise and counterclockwise to
select the desired time unit, time range, or operating mode.
Each selector has a snap mechanism that secures the selector at a
given position. Set the selector at a position at which it is secured.
Do not set it midway between two securing positions or a malfunction
could result from improper setting.
For OFF-time, the desired time unit (sec, 10 s, min, and hrs, or 10 s,
10 min, hrs, and 10 h) is indicated in the OFF-time unit display
window at the upper right corner of the front panel and can be
changed by turning the OFF-time unit selector located below the
OFF-time unit display window.

For PL08 Socket
The protective cover protects the front panel, particularly the time
setting section, against dust, dirt, and water. It also prevents the set
value from being altered due to accidental contact with the time
setting knob.

For PF085A Socket
Note: 1. The Y92A-48B Protective Cover is made of a hard plastic

value.
2. The Protective Cover cannot be mounted if the Panel Cover
(sold separately) is used on the Timer.

Safety Precautions
Note: The undermentioned is common for all H3B@-N models.
A transformer is not used in the power supplies for the H3B@-N.
Therefore, an electrical shock may be received by touching the input
terminals when the power supply voltage is being applied. Take
adequate precautions to protect against electrical shock.
Changing of Settings
NOTICE:
Do not change the time unit, time range, or operation
mode while the timer is in operation or malfunction
could result.
Power Supplies (H3BH-N8)
Connect the power supply voltage through a relay or switch in such a
way that the voltage reaches a fixed value at once or the Timer may
not be reset or a timer error could result.
The H3BH-N8 has a large inrush current; provide sufficient power
supply capacity. If the power supply capacity is too small, there may
be delays in turning ON the output.
Input/Output (H3BH-N8)
The H3B@-N-series models have a transformerless power supply.
Wiring (H3BH-N8)
The H3BH-N8 has a high impedance circuit. Therefore, the H3BHN8 may not be reset if the H3BH-N8 is influenced by inductive
voltage. In order to eliminate any influence of inductive voltage, the
wires connected to the H3BH-N8 must be kept as short as possible
and should not be installed alongside power lines. If the H3BH-N8 is
influenced by inductive voltage that is 30% or more of the rated
voltage, connect a CR filter with a capacitance of approximately 0.1
μF and a resistance of approximately 120 Ω or a bleeder resistor
between the power supply terminals. If there is any residual voltage
due to current leakage, connect a bleeder resistor between the
power supply terminals.
Operation (H3BH-N8)
An interval of 3 s minimum is required to turn on the H3BH-N8 after
the H3BH-N8 is turned off. If the H3BH-N8 is turned on and off
repeatedly with an interval of shorter than 3 s, the internal parts of
the H3BH-N8 may deteriorate and the H3BH-N8 may malfunction.
3 s min.
Power
Output
state 1
If it is required that the output be turned on repeatedly with an
interval of shorter than 3 s, consider using the H3BA-N in mode D
(signal OFF-delay).
Others
Since latching relays are used in the H3BH-N8, output contacts may
become reversed or set to neutral state when an impact is applied to
the Timer. If the Timer has been dropped, be sure to reinspect the
Timer before using it again.
