Wiring the S-2A
Connect a length of 16-gauge wire from the control panel positive to the +12 VDC terminal on
the S-2A display through a 1-amp fuse. Connect a length of 16-gage wire from the control panel
buss bar ground to the negative terminal on the S2A display.
If you are supplying your own solenoid valve, disconnect solenoid valve from current system and
wire solenoid valve to S-2A display using figure 6 on page 4.
If you choose to use the valve provided in the carton, which is non-polarized, wire solenoid valve
to S-2A display using figure 6 on page 4.
Quick Disconnect Style Sensor with 20’ sensor cable is included. The disconnect/connector plug
is located 12” from the red sensor. In the event you need to replace the red sensor, simply
disconnect it at the plug and remove. When reattaching the sensor, make sure the connector
“snaps” into place by pushing the side locks in. This ensures a watertight seal. No need to reroute
or replace the 20’ sensor cable. NOTE: If longer sensor length is necessary, contact your retailer
or our factory for lengths 25’ through 100’.
Sensor Connection
Plug sensor #1 provided with the S-2A into the connector on the backside of display labeled #1. If
installing the optional second sensor, plug sensor #2 into the other connector.
