When no external input-output device is available this connector must be closed
with the supplied mating connector that short-circuits the START/STOP (+) & (-)
and INTERLOCK (+) & (-) inputs with the +24Vdc & GROUND.
Signal Description
START/STOP: input signal (opt isolated) to start or stop the pump.
When the controller is configured for 'Front Panel' operation (default mode), the
front panel can be used to send 'Start/Stop' commands.
When the controller is configured for 'Remote' operation, using the rear panel
mating connector (supplied together with the controller, connects START/STOP
positive signal to the +24 Vdc pin and START/STOP negative signal to the Ground
pin) it is possible to automatically start the pump as soon as the input supply is fed
to the controller ("Plug & Pump").
INTERLOCK: safety input signal (opt isolated) to control the pump rotation
activation.With the supplied mating connector the INTERLOCK (+) signal is
connected to the +24Vdc pin and the INTERLOCK (-) signal to the GROUND pin.
PROGRAMMABLE SET POINT: This is a programmable set point output (open
collector) that can be related to: Frequency, Power, Time, Status. The output is
activated when the reference quantity chosen is higher than the threshold set value.
The output logic can be configured as "high level active" = when the output is active
the pin voltage is low or as "low level active" = when the output is active the pin
voltage is high (+24V).
