TEMPERATURE CONTROL PARAMETER DESCRIPTIONS
Bit Mapped Mode Word (V5000)
The bit mapped Mode Word allows you to enable and disable features, enter new PID parameters, enter
new Alarm Parameters, and specify the format of the output word. There is one Mode Word per loop so
that each loop can be programmed independently. This location is continually read by the temperature
controller.

Description
Turn ON to Read PID and Alarm parameters from V-Memory, the module
turns OFF the bit after the parameters are read
ON = Reverse Acting (cooling)
OFF = Direct Acting (heating)
ON = Temperature Units EC
OFF = Temperature Units EF
ON = Output Format is analog value 0-4095 (@ V5003)
OFF = Output Format is 0.0-100.0% (@ V5003)
ON = PID Control
OFF = ON/OFF Control
ON = Deviation Alarm Enable (@ V5013)
ON = SetPoint Clamp Enable (@ V5015 and @ V5016)
ON = Heater Current Alarm Enable
ON = Start Auto Tune / Module turns OFF the bit when Auto Tune
succesfully completes
OFF = Stop Auto Tune
ON = Auto Tune for PI Control only (force Rate=0)
ON = Minimize Oscillation
OFF = Faster Response
Not implemented, reserved for future use. Do not write 1s to reserved bits.
These bits may be used in the future to enable new features.
ON = Force Heater Output OFF (manual over-ride)
ONN = Force Heater Output ON (manual over-ride)
