MAIN OUTPUT:
SOFT START TIME:
HAND OUTPUT PERCENTAGE:
RAMP - SOAK:
The main control output is selectable between Relay1 / Analog output (available across
terminals 4 and 5) and Relay2 (available across terminals 2 and 3). If main output is selected
as Relay 2, all the control parameters will be applicable to the output connected to Relay 2 but
the setpoint applicable will be Set 1 (main set point). For analog retransmission, the main
output must be set to Relay 2 and the analog output (across 4 and 5) will be used for
retransmission.
Soft start time can be programmed in situations where full output is not required at power ON.
The time duration for the output to rise from 0% to 100% is programmed as soft start time.
This parameter can be used when a fixed percentage of output is desired. For example: If 4-
20mA analog output is being used and the desired output is 12mA, the hand percentage can
be programmed as 50%. This will ensure that the analog output available is fixed 12 mA i.e.
50%. In case of relay output models, the relay ON time and OFF time will be according to the
programmed Hand output percentage i.e. For 50% hand o/p percentage and cycle time
15sec, relay will be ON for 7.5sec and OFF for 7.5 sec.
The setpoint ramp feature can reduce thermal shock to the process, reduce temperature
overshoot on start-up or set point changes, or ramp the process at a controlled rate. The soak
feature can be used to hold the process at a preset temperature for a preset time.
:
Ramp OFF: Controller will be simple PID/ ON-OFF controller with P, I, D
settings/hysteresis setting by user or default.
Ramp HOLD: Suspends the ramp at the last value.
Ramp ON: Initiates the ramp. Ramp rate and soak time settings as programmed by
the user or default.
