FIG. 4-6 MODE CONFIGURATION DESCRIPTION
In the
Modes Menu
a user may select a control mode per circuit, enable or disable circuits, and toggle the soft
start feature.
1. Circuit Enable/Disable
- Enable or disable power output to load for specified circuit.
2. Auto PID Mode
- A closed loop control method that will control the power output based on a PID algorithm.
The proportional, integral, and derivative variables can be modified from the
System Settings Menu
under
PID Settings
.
3. Manual Mode
- An open loop control method that sets the power output to a user-specified percentage.
Manual Mode is also the failover mode from Auto PID or On/Off when the temperature sensor fails.
Set the
output accordingly for the application range of power limit (%)
.
4. On/Off Mode
- A closed loop control method that utilizes Deadband hysteresis values to determine the
power output. The output will turnoff once the process temperature reaches the deadband’s high setpoint
and turns on when the process temperature reaches the deadband’s low setpoint.
