Operating instructions

Field Wire Installation (continued)
3. Secure the field common wire(s) and pump
start relay (or master valve) wire to the
appropriate terminals on the Pump/Com
module. See Figure 6.
4. Momentarily touch each valve control wire
to the Hot Post to activate and identify the
corresponding valve(s).
5. Secure the valve control wires to the sta-
tion terminals in the preferred order of
operating sequence. Station terminals are
numbered left to right, 1–32 (front) and
33–64 (back). Each terminal can accom-
modate two 14 gage (1.5mm
2
) solid copper
wires. See Figure 6.
Note: A loop is provided on the plastic chas-
sis below each output module enabling a
wiring strain relief to be installed when the
optional standard terminal block connector
is used. After connecting the field wires,
install a nylon cable tie through the loop and
around the wire bundle. Ensure the terminal
block is properly mated with the output
module connector after tightening the cable
tie. See Figure 6.
Note: The 3-position switches
provided on the pump/com mod-
ule and the optional station ter-
minal board enable local control
of the field common, pump circuit
and station output. The switch
positions are as follows:
ON (up) – Manually activates the
circuit. The pump, field common
or station output will remain on
until the switch is moved to the
AUTO or OFF position.
OFF (center) – Manually opens
the circuit. Operation of the circuit
will not occur while the switch is in
this position.
AUTO (down) – Enables the circuit
to be automatically controlled
during automatic or manual
(hand-held radio) operation.
CAUTION: To prevent
damage to the station
output circuit fuse, do not
exceed 3 amp load when man-
ually activating multiple sta-
tion outputs.
