Setpoints and related data

No setpoints and related data are specific to unit protection shut down.

Inputs

The input for shut down is a dry contact closure that is wired to shutdown input (SD). This is commonly used for an external smoke detector.

Outputs

No outputs are unique to unit protection shut down.

Operation

Any time the contact opens, all power is removed to the output relay coils. This immediately de-energizes all relay outputs. The control generates an alarm and displays it on the LCD.

Note: Any additional unit interrupt devices, such as float switches or external shutdown relays, must be wired in series with this contact to disable the unit.
