Run status output (J4)
Connect the output device to the C (common) terminal
of the relay connector and either the N/C (normally
closed) or N/O (normally open) terminal as required.
This relay coil is energised when the pump is running.
The default for Relay 2 is run status, on un
models this output (2) can be configured in the control
settings menu.

Configurable remote stop or contact
input - J3
If Analog 4-20mA mode is selected then
terminal J3 will be configured as a remote stop
automatically.
If Contact mode is selected then the input J3
will be configured as a contact input
automatically.

Remote Stop
Connect a remote switch between the
Stop/Contact
terminal and the
+24V
terminal of
the Run/Stop I/P connector (J3). Alternatively a 24V logic input may be applied to the
Stop/Contact terminal, ground to the GND terminal of the adjacent 4-20mA I/P connector
(J2).
The sense of the remote stop input can be configured in software using the control settings
menu.
Remote stop is operational in manual and analog mode.
Contact
To operate the pump in contact mode the remote stop input should be set to "High".
Speed: analog input (J2)
The analog process signal must be applied to the I/P
terminal of the Analog connector (J2). Ground to the
GND connector of the same terminal. In Analog mode
the pump set speed will be proportional or inversely
proportional to the analog input.
4-20mA circuit impedance: 250Ω.
Max current 40mA
Note:
inverting the signal response is set up in
software. Do not invert the polarity of the terminals.
