Table 14 - Remote stop input (J1A), 110 V logic
110 VAC-Stop input
Apply a signal of 85 VAC to 130 VAC across
terminals AC1 and AC2 to stop the pump.
Polarity is not important.
In the default condition the pump will not run
while this signal is applied. In manual and
analog mode, the pump will start when the
signal is removed. The input can be configured
to act in the opposite way in the control settings
menu.
Note:
This input is logical OR with the contact
dose input.
Contact
If contact mode is enabled the pump will
commence a contact dose when an AC input is
applied across the terminals.

Table 15 - Speed: analog input (J4)
Analog
The analog process signal must be applied to
the I/P terminal of the Analog connector (J4).
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.

Table 16 - Speed: analogue output (J3) (Un only)
4-20 mA
A current analogue signal within the range
4-20 mA is available between the O/P (output)
terminal and the GND terminal. The current is
fixed and directly proportional to the pump
speed. 20 mA = maximum speed, 4 mA = zero
speed.
There is also an option to match the scale of the
4-20 mA input if this has been reconfigured by
the user. This option is available in the Control
settings menu.
