Belt Break Fault
If this digital input is active, a belt break fault will be triggered. This can be tied to a belt
break or proximity sensor which would sense a broken drive belt.
Safety Switch Fault
If this digital input is active, a safety switch fault will be triggered.
Low Voltage Relay
Warning
If this digital input is active, a low voltage warning will be triggered.
Low Voltage Relay
Fault
If this digital input is active, a low voltage fault will be triggered.
Phase Sequence Fault
If this digital input is active, a phase sequence fault will be triggered. This is typically
connected to a phase fault relay.
High Vibration Warning
If this digital input is active, a high vibration warning will be triggered. This is typically
connected to a vibration switch mounted on the compressor or motor.
High Vibration Fault
If this digital input is active, a high vibration fault will be triggered. This is typically
connected to a vibration switch mounted on the compressor or motor.
Enclosure Temperature
Warning
If this digital input is active, an enclosure temperature warning will be triggered. This is
typically used to monitor the temperature inside the machine enclosure and protect
against high ambient temperature, dirty package air filters, or cooling fan faults.

typically used to monitor the temperature inside the machine enclosure and protect
against high ambient temperature, dirty package air filters, or cooling fan faults.
Oil Filter Warning
If this digital input is active, an oil filter warning will be triggered. This is typically used
to indicate a clogged or defective filter.
Oil Temperature
Warning
If this digital input is active, an oil temperature warning will be triggered.
Oil Temperature Fault
If this digital input is active, an oil temperature fault will be triggered.
Oil Pressure Warning
If this digital input is active, an oil pressure warning will be triggered.
Oil Pressure Fault
If this digital input is active, an oil pressure fault will be triggered.
Water Pressure
Warning
If this digital input is active, a water pressure warning will be triggered. This is typically
utilized to monitor cooling water pressure on water-cooled machines.
Water Pressure Fault
If this digital input is active, a water pressure fault will be triggered. This is typically
utilized to monitor cooling water pressure on water-cooled machines.
Condensate Drain
Warning
If this digital input is active, a condensate drain warning will be triggered.
Condensate Drain Fault If this digital input is active, a condensate drain fault will be triggered.
Reset Alarms
This function is used to acknowledge all active alarms on the system. The functionality
is identical to pressing the
Reset All
button on the Alarms page.
OK to Start
This function is used as a start permissive for the controller. If it is assigned and not
active, the compressor will not start the motor until this signal becomes active.
OK to Load
This function is used to delay opening the inlet valve on a compressor until it becomes
active.
Motor Lubrication
System
This function is used to monitor Gardner Denver automatic motor lubrication systems.
A set of controls and monitoring logic is tied to this input that monitor the automatic
lubricator for proper operation and fault signals.
