Figure 12 for connecting 4-wire receivers.
NOTE: IF THE 4 WIRE RECEIVER INSTRUCTIONS SHOW
THAT TWO OF THE WIRES ARE OF THE SAME COLOR
AND ARE COMMON CONNECTIONS INSIDE THE
RECEIVER, ONE OF THESE WIRES SHOULD BE
CONNECTED TO TERMINAL #1 (COMMON) AND THE
OTHER TO ONE SIDE OF THE TRANSFORMER.
WIRING A 3-BUTTON STATION
See Figure 13 for instructions on wiring a 3-button station.
NOTE:
The STOP button is normally OPEN.
WIRING A KEYPAD OR TELEPHONE ENTRY
SYSTEM
Install according to the manufacturer's instructions.
BI-PARTING APPLICATION
In a bi-parting application, two operators are required, one operating in
a left-hand mode, the other in a right-hand mode. Both must be wired
for AC power (as previously described) but share a common set of
input controls. In general, all of the preceding instructions concerning
installation of individual operators can be followed in a bi-parting
application except the following:
Choose one of the operators to be the PRIMARY and the other to be
the SECONDARY. Route all of the control wiring to the PRIMARY
operator first. This will prevent grounding looping problems which can
occur when more than one COMMON or ground wire is attached
between separate operators. All accessory equipment should also be
wired to the PRIMARY.
From each of the control inputs with accessory equipment attached, run
a separate wire to its counterpart terminal on the SECONDARY
operator . 1/4" disconnect terminals for each command input are
provided for this purpose. Use conduit SEPARATE from AC power
service. See Figure 14 for the correct wiring.
FINAL INSTALLATION CHECKLIST
1. Use a voltmeter to assure the service voltage to the
operator is 115 VAC. Connection to 220 VAC service is
the most common cause of board failure in new
installations and is NOT COVERED BY WARRANTY!
2. No accessory equipment is installed in the control box.
3. All wires attached to the 11 position terminal strip or
the 3-terminal connector on the control box are well
clear of the motor V-belt and the limit switches.
4. The junction box cover is securely fastened .
