RELAY CONTROL SYSTEM ELECTRICAL INSTRUCTIONS
The wiring for the additional control station is now complete. You can continue to add control
stations by following this same procedure. Connect the blue, white, and green wires to the
corresponding terminals in the operator. Disconnect the red wire from the previous station
from the #9 Terminal, connect it to the yellow wire for the new station (wire nut), and connect
the red wire for the new station to Terminal #9.
ADDING PULL CORD OR SINGLE BUTTON CONTROL STATIONS:
The External Operator supports N/O (Normally Open) Pullcord Switches, N/O Single Button
Control Stations, and any other N/O dry contact. All N/O switches should be wired in PARALLEL
and the wiring junctions can be made either at the switches (daisy-chain) or at the External
Operator (Homerun). Switches should be connected using two-conductor wiring (supplied) and
terminated at the External Operator at the #3 (COM) and #4 (O/C) terminals. Color codes are
not important.
