INSTALLATION - WIRING 1
In most cases, the interface board or solenoids in the host machine will have a common (i.e their
negative terminals are all linked by a common wire).
The switches S1 & S2 can be left switched to common (up position), and the single(common) wire
taken to the B rail.
Note:
If a signal is applied to Input 2 before Input 1 then the unit will assume that a Pre-wash is not
occurring and will ignore subsequent signals to input 1 until the unit has reset.

Lorem ipsum
B Rail
(Negative)
With the switches in an
upright position, a
common (neutral/nega-
tive) input signal can be
taken to the B Rail.
A Rail
(Positive)
The positive (live) signal
from each input must be
taken to the relevant
connection on the A Rail.
Seperate connections
are provided on input 2
for Hot & Cold wash
signals.

Max Size = 0.5mm

Current = 0.5A
Safety Warning
If low voltage signals are used, signal wires to the A
and B rails should be routed in separate cable from the
main power to the unit.
Suitable grade wire must be used.
INPUT 1 - Pre-Wash
INPUT 2 - Main Wash
