Red Lion TCU - Manual (Page 6)

CONTROLLER PROGRAMMING
The TCU 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:
Unprotected Parameter Mode
Configuration Parameter Mode
Protected Parameter Mode
Hidden Function Mode
These four programming modes allow the controller to adapt to any required
user-interface level.
UNPROTECTED PARAMETER MODE *
The unprotected parameter mode is accessible when program disable is
inactive or when the proper access code number from the protected mode is
entered.The configuration parameter modes can be accessed only from this mode.
“SP” - Enter Setpoint
“OP” - Enter output power
“ProP” - Enter proportional band
“Intt” - Enter integral time
“dErt” - Enter derivative time
“rtio” - Enter Remote Setpoint ratio value
“bIAS” - Enter Remote Setpoint bias value
“SP-2” - View internal cascade secondary setpoint
demand
“Pb-2” - Enter internal cascade, secondary
proportional band
“It-2” - Enter internal cascade, secondary integral
time
“dt-2” - Enter internal cascade, secondary
derivative time
“AL-1” - Enter value for alarm #1
“AL-2” - Enter value for alarm #2
“CNFP” - Select basic configuration mode
“End” - Return to normal display mode
* These parameters may not appear due to option configuration or other
programming.
CONFIGURATION PARAMETER MODE
The configuration parameter mode allows the operator to set-up the basic
requirements of the controller. It is divided into sections which group together
related programming steps, such as inputs, outputs, alarms, etc. Upon
completion of each section, the program returns to the configuration selection
stage allowing the user to return to the normal display mode.

“SPLO” - Enter setpoint lower limit
“SPHI” - Enter setpoint higher limit
“SPrP” - Enter setpoint ramp rate
“InPt” - Select user input function *
“HCur” - Enter full scale heater current *
Configuration 2, Outputs
“CYCt” - Enter time proportioning cycle time
“OPAC” - Select control action

“OPFL” - Enter probe fail power preset
“OPdP” - Enter output control dampening
“CHYS” - Enter ON/OFF control hysteresis
“tcod” - Select auto-tuning dampening
“ANAS” - Select linear DC output assignment *
“ANLO” - Enter linear DC output low scaling value *

SETPOINT MASTER CONTROL
Setpoint Master Control allows automatic setpoint changes to slave
controller units (up to 50 units total) from a master TCU controller.
The linear DC output of the master is looped with the second analog
input of the slave TCU controllers. Each slave unit can have unique
remote setpoint ratio and bias values.
Setpoint Slave Configuration Parameters
“OPEr” - Select remote setpoint mode
“root” - Select second input square root
Linearization
“dPt2” - Select second input decimal point
“dSP1” - Enter scaling units of second input
“INP1” - Enter scaling units of second input
“dSP2” - Enter scaling units of second input
“INP2” - Enter scaling units of second input
“SPLO”
“SPHI”
- Limit range of remote setpoint
“SPrP” - Limit rate of change of remote
setpoint
Setpoint Slave Operational Parameters
“rtio” - Second input ratio
“bIAS” - Second input bias
