Action

Go to CONFIGURATION DISCRETE CONTROL

ON/OFF.

ATTENTION: Any value entered for one of these control- related parameters will take effect as soon as it is entered.

Use this screen to specify the length of the cycle period for all timers.

To configure an individual timer associated with one of the relays, select it from the menu.

The relay assigned to this On/Off control output during I/O setup will already be filled in. (This is read-only information.)

Specify the process value or computed value to be used as the input.

Specify whether relay activation should occur when the input’s value exceeds the setpoint (HIGH action) or falls below the setpoint (LOW action).

Enter the setpoint.

If desired, specify a deadband. (Once the output is ON, it will remain ON until the controlled variable differs from the setpoint by at least the value of the deadband.)

Enter the percent of the cycle period that the relay should stay on when the setpoint is reached.
