Channel Pids - Tidal Engineering Synergy Series Technical Manual

7.3 Channel PIDs

The Channel PIDs screen shows a third column when cascade mode is enabled for the channel. All columns
show values for the following parameters: Pn, In, Dn, PID, Err, Setpoint, Actual, P.B., Reset and Rate.
♦
Setpoint & Actual values under Heating and Cooling is air temperature.
♦
Setpoint value under Heating and Cooling is the calculated air temperature setpoint from the Cascade
PID loop.
♦
Cascade PID parameters: Pn, In, Dn, PID values range from -100 to +100%.
Note: -100% corresponds to the Cascade Low Limit temperature
Note: +100% corresponds to the Cascade High Limit temperature
The values in the Heating & Cooling columns range from 0 to 100%See
information on Data Logging Capacity calculations.
Synergy Controller Technical Manual, Revision H
The Setpoint and Actual numbers in the cascade
column are the desired setpoint, and actual
temperature of the product inside the chamber.
