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.
CONTROL OPERATION DESCRIPTION
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 LOCK key will enable the security feature.
Parameter Configuration Display
Holding the MODE KEY 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.
