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
station 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
accommodate two 14 gage (1.5mm
2
) solid
copper wires. See Figure 6.
Note: A loop is provided on the plastic
chassis 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.

provided on the pump/com module and the
optional station terminal 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 manually activating multiple
station outputs.
Selecting the Radio Frequency
The OSMAC G3 controller has 6 pre-programmed user-selectable radio frequencies. The frequencies are programmed
at the factory or by the distributor prior to delivery of the satellite. However if a frequency change is desired, any of the 6
pre-programmed frequency channels can be modified to any desired radio frequency.
Important: The base station transmitter and satellite must be set to the same frequency to enable communication.
