Warning
This signal indicates that a warning other than a maintenance alarm is present on the
machine.
Fault
This signal indicates that a fault is present on the system. Note that an output that is
not powered by the ESTOP must be used for the programmable output channel for
this signal to remain active during an ESTOP fault.
Any Alarm
This signal indicates that an alarm is present on the machine. Any fault or warning
will trigger this output.
Secondary Pressure
Active
This signal indicates that the secondary pressure band is currently active, due to the
Secondary Pressure Timer or digital input.
Timer Control
This signal indicates that the compressor is operating under timer control.
Request to Start
This signal can be used in conjunction with the OK to Start digital input function. If
the controller needs to start the motor due to conditions such as pressure
requirement, it will activate this output.
Request to Load
This signal can be used in conjunction with the OK to Load digital input function. If
the controller needs to load the machine, it will activate this output.
Water Stop Valve
This function is used to control a water valve on water-cooled machines. Depending
on the configuration of the machine, the water stop valve may be controlled
continuously or through a thermostatic algorithm based on the discharge temperature
of the compressor.
Condensate Drain
This function is used to control a condensate drain. An internal timer and additional
logic is used to activate the drain output periodically.
Heater Start
This function is used to control an external heater based on the various temperature
readings on the package.
Dryer Start
This signal is used to start an external dryer. It is used in conjunction with the Dryer
Pre-run Time control setting, as well as the Dryer running digital input, if desired.
External Reset
This signal is used to send a reset command to an external device. This is tied to the
Reset All button on the Alarm page used to acknowledge faults and warnings.
Motor Lubrication
This signal is used to control Gardner Denver automatic motor lubrication systems.
Use of this output should always be combined with the Motor Lubrication digital input
function for monitoring.
