In some cases, the interface board or solenoids in the hose machine are
not
common.
For
example:
The softener solenoid on some machines is not linked via a common wire to the other
solenoids.
If this is the case, the signal must be isolated from the common B rail on the Board. This is done
by Switching the appropriate switch (S1 & S2 to isolated, ie. Downward position). If in doubt switch
the appropriate switch for each incoming signal source.
FAILURE TO SWITCH THE APPROPRIATE SWITCH WOULD RESULT IN UNIT FAILURE.
DO NOT ATTEMPT TO SWITCH THE SWITCHES WHEN THE POWER IS ON.
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.

B
RAIL
B Rail
(Negative)
With the switches in an
upright position, a
common (neutral/nega-
tive) input signal can be
taken to the B Rail.
Separate connections
are provided on input 2
for Hot & Cold wash
signals
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.
Signal Inputs 90v-240v AC or DC
Example
Recommmended Wiring
Max Size = 1.5mm²
Max Size = 0.5mm²
Current = 0.5

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
INPUT 3 - Rinse
Power Supply
100-240v(AC) 50/60Hz
Sourced from a point which
is isolated when the host
