GENERAL DESCRIPTION
SAFETY SUMMARY
All safety regulations, local codes and instructions that appear in this and
corresponding literature, or on equipment, must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment connected to
it. If equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the unit.
The Large Display Timer and Cycle Counter is a versatile display that
functions as an Elapsed Timer or Preset Timer, with full-featured user
programmability. The meter includes a built-in Cycle Counter, relay output and
serial communications capability. The 6 digit displays are available in either
2.25" or 4" high red LED digits with adjustable display intensity. The 2.25" high
models are readable up to 130 feet. The 4" high models are readable up to 180
feet. Both versions are constructed of a NEMA 4X/IP65 enclosure in light
weight aluminum.
The Timer has two signal inputs and eight input operating modes. These
modes provide level active or edge triggered start/stop operation. The Timer
features 18 selectable timer ranges to cover a wide variety of timing applications.
The built-in Cycle Counter can be linked to timer operation to count timing
cycles, or function as a totally independent counter, accepting count speeds up
to 500 Hz. The display can be toggled either manually or automatically between
the Timer and Counter values.
In addition to the Timer/Counter inputs, a programmable User Input is
provided to perform a variety of meter functions. DIP switches are used to
configure the inputs for current sinking (active low) or current sourcing (active
high) operation.
The Setpoint Output can be assigned to the Timer or Counter value, and
configured to suit a variety of control and alarm requirements. The meter also
includes RS232 or RS485 serial communications.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
The protective conductor terminal is bonded to conductive
parts of the equipment for safety purposes and must be
connected to an external protective earthing system.

EMC INSTALLATION GUIDELINES
effective. The following EMI suppression devices (or equivalent) are
recommended:
Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:
Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)
6. To protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide
varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.
b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor
switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid state
outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000
7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.
Although Red Lion Controls Products are designed with a high degree of
immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.
1. A unit should be mounted in a metal enclosure, which is properly connected
to protective earth.
2. Use shielded cables for all Signal and Control inputs. The shield connection
should be made as short as possible. The connection point for the shield
depends somewhat upon the application. Listed below are the recommended
methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the
unit is mounted.
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is over 1 MHz.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors, feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run through metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors, control
relays, transformers, and other noisy components.
4. Long cable runs are more susceptible to EMI pickup than short cable runs.
5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is

WIRING OVERVIEW
1
Electrical connections are made via pluggable terminal blocks located inside
the meter. All conductors should conform to the meter's voltage and current
ratings. All cabling should conform to appropriate standards of good installation,
local codes and regulations. It is recommended that the power supplied to the
meter (DC or AC) be protected by a fuse or circuit breaker. When wiring the
meter, compare the numbers on the label on the back of the meter case against
those shown in wiring drawings for proper wire position. Strip the wire,
according to the terminal block specifications. Insert the lead under the correct
screw clamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.)

unit on the left side for the LD2 and on the right side for the LD4.
TXD 1

TBD
RS232 Communications
232
RS232 is intended to allow two devices to communicate over distances up to
50 feet. Data Terminal Equipment (DTE) transmits data on the Transmitted Data
(TXD) line and receives data on the Received Data (RXD) line. Data Computer
Equipment (DCE) receives data on the TXD line and transmits data on the RXD
line. The LD emulates a DTE. If the other device connected to the meter also
emulates a DTE, the TXD and RXD lines must be interchanged for
communications to take place. This is known as a null modem connection. Most
printers emulate a DCE device while most computers emulate a DTE device.
Some devices cannot accept more than two or three characters in succession
without a pause in between. In these cases, the meter employs a busy function.
As the meter begins to transmit data, the RXD line (RS232) is monitored to
determine if the receiving device is “busy”. The receiving device asserts that it
is busy by setting the RXD line to a space condition (logic 0). The meter then
suspends transmission until the RXD line is released by the receiving device.

RS485 Communications
The RS485 communication standard allows the connection of up to 32
devices on a single pair of wires, distances up to 4,000 ft. and data rates as high
as 10M baud (the LD is limited to 38.4k baud). The same pair of wires is used
to both transmit and receive data. RS485 is therefore always half-duplex, that is,
data cannot be received and transmitted simultaneously.

It is recommended all programming changes be made off line, or before
installation. The meter normally operates in the Display Mode. No parameters
can be programmed in this mode. The Programming Mode is entered by
pressing the PAR key. If it is not accessible, then it is locked by either a security
code or a hardware lock (See Module 3).
The Programming Mode is exited by pressing the PAR key with
displayed. This will commit any stored parameter changes to memory and return
the meter to the Display Mode. (If power loss occurs before returning to the
Display Mode, verify recent parameter changes.)
PROGRAMMING TIPS
MODULE ENTRY (SEL & PAR KEYS)
It is recommended to start with Module 1 and proceed through each module in
sequence. When programming is complete, it is recommended to record the
parameter programming and lock out parameter programming with the user input
or programming security code.
The Programming Menu is organized into five modules. These modules group
together parameters that are related in function. The display will alternate between
and the present module. The SEL key is used to select the desired module.
The displayed module is entered by pressing the PAR key.
FACTORY SETTINGS
MODULE MENU (PAR KEY)
Factory Settings may be completely restored in Module 3. This is useful when
encountering programming problems.
Each module has a separate module menu (which is shown at the start of each
module discussion). The PAR key is pressed to advance to a particular parameter
to be changed, without changing the programming of preceding parameters.
After completing a module, the display will return to . Programming
may continue by accessing additional modules.
ALTERNATING SELECTION DISPLAY
In the explanation of the modules, the following dual display with arrows will
appear. This is used to illustrate the display alternating between the parameter
on top and the parameter’s Factory Setting on the bottom. In most cases,
selections and values for the parameter will be listed on the right.
SELECTION / VALUE ENTRY
For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The SEL and RST keys are used to
move through the selections/values for that parameter. Pressing the PAR key,
stores and activates the displayed selection/value. This also advances the meter
to the next parameter.
For numeric values, the value is displayed with one digit flashing (initially the
right most digit). Pressing the RST key increments the digit by one or the user
can hold the RST key and the digit will automatically scroll. The SEL key
will select the next digit to the left. Pressing the PAR key will enter the value and
move to the next parameter.

METER ADDRESS
This parameter selects the meter values transmitted in response to a Print
Request. A print request is also referred to as a block print because more than
one parameter can be sent to a printer or computer as a block.
Selecting displays a sublist for choosing the meter parameters to appear
in the print block. All active parameters entered as in the sublist will be
transmitted during a block print. Parameters entered as will not be sent.
The “Print All” () option selects all meter values for transmitting
(), without having to individually select each parameter in the sublist.
Note: Inactive parameters will not be sent regardless of the print option
setting. For example, the Cycle Counter and Cycle Counter Start values will
only be sent when the Cycle Counter is enabled. If disabled, these parameters
are inactive and will not be transmitted. Likewise, only the Setpoint parameters
that apply to the programmed Setpoint Output Action will be transmitted.
Select either 7- or 8-bit data word length. Set the word length to match the
other serial communications equipment on the serial link.
Enter the serial node address. With a single unit, an address is not needed
and a value of zero can be used (RS232 applications). Otherwise, with multiple
bussed units, a unique address number must be assigned to each meter. The
node address applies specifically to RS485 applications.

Command Response Time
At the beginning of time interval t3, the meter responds with the first
character of the reply. As with t1, the time duration of t3 is dependent on the
number of characters and baud rate of the channel. At the end of t3, the meter is
ready to receive the next command.
The meter can only receive data or transmit data at any one time (half-duplex
operation). During RS232 transmissions, the meter ignores commands while
transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending
another command. This allows enough time for the meter to process the
command and prepare for the next command.
At the start of the time interval t1, the computer program prints or writes the
string to the com port, thus initiating a transmission. During t1, the command
characters are under transmission and at the end of this period, the command
terminating character (* or $) is received by the meter. The time duration of t1
is dependent on the number of characters and baud rate of the channel.
t3 = (10 times the # of characters) / baud rate
The maximum serial throughput of the meter is limited to the sum of the
times t1, t2 and t3.
NO REPLY FROM METER
Ready
t1 = (10 times the # of characters) / baud rate
At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time
interval t2 varies. If no response from the meter is expected, the meter is ready
to accept another command.
If the meter is to reply with data, the time interval t2 is controlled by the use
of the command terminating character. The ‘*’ terminating character results in
a response time of 50 msec. minimum. This allows sufficient time for the
release of the sending driver on the RS485 bus. Terminating the command line
with ‘$’ results in a response time (t2) of 2 msec. minimum. The faster response
time of this terminating character requires that sending drivers release within 2
msec. after the terminating character is received.

Communication Format
Start Bit and Data Bits
Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the least
significant bit of the ASCII encoded character is transmitted, followed by the
remaining data bits. The receiving device then reads each bit position as they are
transmitted.
Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character. The voltage level conventions depend on the interface
standard. The table lists the voltage levels for each standard.

Parity Bit
After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit) is either even or odd. This bit is used by the receiver
to detect errors that may occur to an odd number of bits in the transmission.
However, a single parity bit cannot detect errors that may occur to an even
number of bits. Given this limitation, the parity bit is often ignored by the
receiving device. The LD Timer ignores the parity bit of incoming data and sets
the parity bit to odd, even or none (mark parity) for outgoing data.
* Voltage levels at the Receiver
Data is transmitted one byte at a time with a variable idle period between
characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit,
an optional parity bit and one or more ending stop bits. The data format and
baud rate must match that of other equipment in order for communication to
take place. The figures list the data formats employed by the meter.
Stop Bit
The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2
stop bits are sent from the meter.
