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.

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.
Parameter Configuration
PV SV
FUnC timE Sets the controller to function as a timer.
t mode UP Sets the display to count up or down.
down
t otmd Sets the output timing functions. See the timing functions
section or page 9 for detail description of each timing
function.
t Unit Sets the display units of measure. See below table for a
list of the available units.
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.
