parallel with the pump NORMAL output signal, that is, the (normally closed) valve opens
when the normal signal becomes acve (pump a
t speed) and closes when stop is selected or
there is a fault condion. Reacon me will be in line with valve selecon. The output signal
is 24 V d.c.
The connector is shown in Figure 3 on page 13 with the polarity of the pins marked when
the valve is energized.
The auxiliary connector is regulated to 24 V d.c. to control the accessories. If the auxiliary
load current exceeds the value in Table 1 on page 13 the output will shut down to protect
the pump controller.
Recommended mang plugs for this connecon are detailed in Table 2 on page 13.
