GETTING STARTED
1. Install the control as described on page 4.
2. Wire your control following the instructions on page 5. Please read the Precautions
section located at the end of this manual before wiring the control.
INSTALLATI N
Mount the instrument in a location that will not be subject to excessive temperature, shock,
or vibration. All models are designed for mounting in an enclosed panel.
Select the position desired for the instrument on the panel. Prepare the panel by cutting
and deburring the required opening per the panel cut out dimensions listed below. Follow
the mounting instructions listed on page 4. Lastly, wire the controller per the appropriate
wiring diagram listed on page 5.

Step 1: From the front of the panel, slide the controller housing through the cut out. The
housing gasket should be against the housing flange before installing.
Step 2: Slide the mounting collar over the housing from the rear of the panel.
Step 3: Push the mounting collar forward until the bracket stops at the panel wall.
Step 4: Insert and tighten the screws on the bracket to secure the controller in place.
(The screw torque should be 0.8 kgf-cm).

FR NT KEY FUNCTI NS
ey functions are as follows:
MODE: Pressing the Mode key advances the display to the next menu
item and saves any changed parameter values.
UP ARROW: Increments a value or changes a menu item. If pressed while
in the home display, the set point value will be increased.
DOWN ARROW: Decrements a value or changes a menu item. If
pressed while in the home display, the set point value will be decreased.
LEFT ARROW: Changes the selected digit to the left. This is used to
quickly change set point values for large values.
RESET: Clear and reset the PV display.
LOC : Press to enter secure mode. See Security Feature section for
more information.

Page 7
SECURITY FEATURES
The Series LCT216 has two built-in security lock settings to prevent unauthorized personnel
from changing parameter settings.
The LoC1 setting affects all parameters in the controller. If LoC1 setting is enabled, the
operator will have to unlock the controller to make any changes to the controller’s
parameters
The LoC2 setting affects all parameters except the set point and the reset function. If LoC2
setting is enabled, the only parameters that the operator will be able to change are the set
point and resetting the process value. In order to change any other parameters, the operator
will have to unlock the control before making a change.
In order to unlock the control, the operator must depress the MODE and LEFT ARROW key
simultaneously.
C NTR L PERATI N DESCRIPTI N
Home Display
The HOME display is the normal display while the control is operating. If no errors or
functions are active, the HOME display will indicate the process value on the top display and
the set value on the bottom display. Below the set value, the current mode of operation will
be shown as TAC (tachometer), CNT (counter), or TMR (timer). There will also be a
descriptor for the time units and type of counter operation.
While in the HOME display, the user can use the UP ARROW, DOWN ARROW, and LEFT
ARROW keys to change the set point value. The RESET key will clear the process value.
The LOC key will enable the security feature.
Parameter Configuration Display
Holding the MODE EY for 3 seconds will enter the parameter configuration display. Once
in the parameter configuration display, the parameter will be listed in the top display and the
value of that parameter will be listed in the bottom display. Pressing the MODE key will cycle
through the parameters for the respective operation modes. The UP and DOWN arrows
change the values of the parameters. The MODE key must be pressed to save any changes.
Return to the HOME display by holding the MODE key for 3 seconds.

TIMER SETTINGS
The timer function of the series LCT216 takes a signal input to start a timing sequence. The
sequence can be paused using the GATE input or reset using RST1 input. Use the below
parameters and timing functions to configure the timer.

T oUt 1 Sets the pulse width (t) for output 1. The default output timeis
0.02 seconds. If you wish the system to keep the operation of
the output, please set the output time to 0.00 seconds.
rtSr Sets the minimum pulse width at either 1 msec or 20 msec.
inPtLC Sets the transistor input type to NPN or PNP. For contact input,
the selection can be either PNP or NPN, but the selection will
determine whether the connection is to terminal 11 or terminal 6.
See the input connection diagrams on page 5.

FUnC Cont Sets the controller to function as a counter
CntFUn Select the counter to perform single stage counting, two
stage counting, batch counting, total counting or dual
counting.
STAGE1 Controller has a single process value and set point value.
Output 2 will be the same as output 1.
STAGE2 Controller has up to two set point and process values. The
operation is based on the input modes and output types.
bAtCH Controller can be set to count batch processes. In this mode,
the counter will count up until it reaches the set value and then will
increment the batch present value by one. The process will
continue until the batch set point value is reached.
totAL Controller has a single set point. The display can show the
present value since last reset or total counts.
dUAL Controller will either add or subtract the counts from the two
counter inputs.
C inPt Counter input mode can be selected to count up or down when a
counter input signal is received.
UP The present value will increase with each counter input signal.
doun The present value will decrease with each counter input signal.

Page 11
Ud A Command up / down setting will increase or decrease the
present value with each counter 1 input signal depending on if
counter 2 input is engaged. When counter 2 input is engaged, each
counter 1 input signal will decrease the count.
Ud b Individual up / down setting will increase the present value with
each counter 1 input signal and decrease with each counter 2 input
signal.
Ud C Quadrature up / down uses the order of the inputs to determine
whether to count up or down. If counter input 1 leads counter input
2, the unit will count up. If counter input 2 leads counter input 1, the
unit will count down.

below for more information.
C SPEd Maximum Input Frequency can be set from one count per second up
to 10,000 counts per second.
Point Sets the number of digits to the right of the decimal point on the

PSCALE Pre-Scale is used when converting the process value’s units of
measure. This value is commonly used to convert the input
frequency (counts per second) to a rotational speed (rpm) using the
below equation.
Frequency (Hz) * Pre-Scale = Rotation Speed (rpm)
Pre-Scale = 60 / n (where n = number of pulses per
revolution).
St tAC Initial Power Up Interrupt delays the output from triggering for up to
99.9 seconds.
St AvG Input Filter allows the tachometer to average 2, 4, or 8 readings to
give a more stable reading. (1= 2 data points, 2 = 4 data points, and
3 = 8 data points).
rtSr Minimum Width of Reset Signal determines how long the
reset terminals must be engaged to reset the device.

sure to tighten them properly.
2. Prevent dust or metallic debris from falling into the device and cause
malfunctions.
3. DO NOT modify or uninstall the device.
4. DO NOT use empty terminals.
5. Make sure the wires are correctly connected to proper terminals.
6. eep away from high-voltage and high-frequency environment during
installation in case of interference.
7. Prevent using the device in premises which contain: dust or corrosive gas, high
humidity, high radiation, vibration and shock.
8. LCT216 is an open-type device. Make sure to install it in an enclosure to
prevent dust, humidity in case of an electric shock.
9. Please make sure the power cables and signal device are installed correctly
before switching on the power; otherwise serious damage may occur.
10. DO NOT touch the terminals or repair the device when the power is on;
otherwise an electric shock may occur.
11. Please wait for one minute after the power is switched off to allow the capacitor
to discharge and DO NOT touch the internal wiring within this period.
12. Use dry cloth to clean the device. DO NOT use acid or alkaline liquid to clean
the device.

LCT216 is an OPEN-TYPE device. They are intended for installation completely within
an overall panel and for use in counting or timing applications. If it will cause series
injury to workers or damages on other equipment when used in a dangerous environment, please make
sure it is installed in an automatic safety protection device.
WARNING
1. When the power is on, DO NOT touch the AC terminals in case an electric shock
may occur.
2. Make sure the power is disconnected when you check the unit inside.
