Auxiliary Outputs (P/N 01020748)
The auxiliary board (Figure 34) comes in the parts pack of the HE 1.5" Twin's secondary valve. It has four 24 VAC outputs
for driving 24VAC control valve motors, energizing 24VAC relay coils, or 24VAC solenoids directly. Each solid state triac
output is capable of handling up to 4 Amps maximum; HOWEVER, the 24VAC transformer determines how much total
current is available. Max supply current of the 01014897 transformer is only 2.1 Amps, so the sum of all loads on the triac
outputs should never exceed the maximum that the transformer can supply. The Auxiliary Outputs (see Figure 35) can
be programmed to be "normally off" (output stays OFF until the designated time, it is needed to be ON) or "normally on"
(output stays ON until the designated time, it is needed to be turned OFF).

Aux Output 1 is used to power the 24 VAC drive motor found on all valves. When Aux Output 1 is used for this, then Aux
Output 4 is automatically configured to operate a solenoid which can be used for a standby or blocking. Aux Output 4 is
powered during all cycles except service, and unpowered during service.
For example, Figure 36 shows how the timing would work if an auxiliary output is set to NORMALLY OFF. The cycle posi-
tion is set to BACKWASH, the delay minutes setting is greater than zero, and ON minutes is greater than zero.
