CONTROLLER PROGRAMMING
The model PSC has been designed to reduce the operator interaction with the
controller while still maintaining a high degree of control accuracy and user
flexibility. Front panel program disable allows all of the controller’s set-ups to be
locked-out from further operator intervention after the initial parameter set-up.
The programming of the controller is divided into four sections:
Hidden Mode
Protected Mode
Unprotected Mode
Configuration Mode
These four programming modes allow the controller to adapt to any required
user-interface level.
UNPROTECTED PARAMETER MODE
The unprotected mode is accessible when program disable is inactive or when
the proper access code number from the protected mode is entered. Only from
this mode can the configuration modes be accessed.
“SP” - Enter setpoint *
“OPOF” - Enter %output power offset *
“OP” - Enter output power *
“ProP” - Enter proportional band
“Intt” - Enter integral time *
“dErt” - Enter derivative time *
“AL-1” - Enter value for alarm #1 *
“AL-2” - Enter value for alarm #2 *
“CNFP” - Select basic configuration module
“End” - Return to normal display mode
PROTECTED PARAMETER MODE
*
The protected mode is accessible when program disable is active, also this
mode prevents access to the configuration modes without the proper access code
number. Only the parameters that are selected in the configuration 3 parameter
lock-outs section can be accessed.
“ProP” - Enter proportional band
“Intt” - Enter integral time
“dErt” - Enter derivative time
“AL-1” - Enter value for alarm #1
“AL-2” - Enter value for alarm #2
“CodE” - Enter access value to unprotected mode
* These parameters may not appear due to option configuration or other
programming.
HIDDEN FUNCTIONS MODE
*
The hidden mode is accessible from the normal operating mode by holding
the PAR button for 3 seconds. The five functions in this mode may be locked-out
individually in configuration 3 parameter lock-outs section.
“ CP” - Invoke control point x
“Prun” - Control ramp/hold profile state
“trnF” - Transfer between automatic (PID) control and Manual control
“tUNE” - Invoke/Cancel PID auto-tune
“ALrS” - Reset latched alarms
* These parameters may not appear due to option configuration or other
programming.
OUTPUT VARIATIONS WITHOUT RS485 OPTION
The Dual Alarm or the Secondary with Alarm output, without the RS485
option, has independent outputs. Therefore, the secondary output and/or alarm
output(s) can be installed with any combination of output modules.
OUTPUT VARIATIONS WITH RS485 OPTION
The Dual Alarm or the Secondary with Alarm output, with RS485 option,
does not have independent outputs. In this case, the secondary output and/or
alarm output(s) must have the same type of output modules installed since they
share the common terminal.
OUTPUT MODULES
Units equipped with RS485 option must have the Dual Alarm or Secondary
w/alarm options fitted with the same type of output modules. The controller’s
main output (OP1) can be fitted with any output module. Output modules are
shipped separately and must be installed by the user.
TYPICAL CONNECTIONS
Relay:
