PIN NAME DESCRIPTION
36
37
VALVE1 (SOL1)
VALVE2 (SOL2)
Solenoid valve output pins. 36: VALVE1 (SOL1); 37: VALVE2 (SOL2)
These pins are closed for the duration of the STAGE 2 input.
Output between SQD and HOLD.
When the off time (OFF) is set, this pin is output between SQZ and HOLD after the
second sequence.
The contacts are rated at 120V AC or 24V AC/DC at 0.5A (semiconductor
switches).
Use a solenoid valve with a current capacity of 0.5A or less.

SECONDARY
VOLTAGE
Secondary voltage input pins. Internally connected to the IT XFMR sense connector.
If IT XFMR sense cable not used may be connected directly to electrodes.
40 INT +24VDC OUT Jumpered from Pin1 to provide drive voltage to Contactor Solid State Relay
41 CONTACTORS Switch closure between Pin 40 and Pin 41 will engage the optional contactor
42 CONTACTOR N.O.
Detect position of contactors between pin 42 and 43: contactors normally open
(optional)

CONTACTOR COM Contactor Aux contact common (optional)
44 CONTACTOR N.C.
Detect position of contactors between pin 44 and 43: contactors normally closed
(optional)

CURRENT COIL
Current coil input, used for secondary current feedback. Internally connected to the
IT XFMR sense connector. If XFMR sense cable not used may be connected
external current coil.
