Essential Services

Description

The Essential Services feature allows full-power bypass mode control of the motor during an emergency scenario. Activation of Essential Services overrides any other selected operation. Essential Services ensures that the bypass contactor will not open when a safety input or overload opens. Power goes directly to the motor.

NOTES:

1.If using both the Interlock and Essential Services features, Essential Services waits 10 seconds for the Interlock to confirm the safety condition (such as opening a damper). After the 10-second delay, Essential Services controls the motor regardless of the Interlock safety condition status.

2.Use extreme care when using the Essential Services mode. All safety circuits are no longer active (including motor overload and safety inputs to the Controller board).
