14. TORQUE MOTOR ELECTRIC CONNECTION
The torque motor connects very easily to the cord reel power source with color coded quick connect wire terminals. The torque arm drive
motor cord is installed to the assembly junction box at the factory. Only the quick connect terminals require termination in the field as
detailed below. The following cord installation procedures apply to wall guide type installations only. The cord is positioned through the
torque motor side cord keeper, then down and around to the bottom knockout of the counter-torque’s junction box. Use the provided SJO
cord connector and conduit locknut. Hand tighten the SJO cord connector friction nut until it grips the cable securely. Connect the quick
connect terminals to matching color of the mating cord reel quick connect terminals.
Note: It is critical that the torque motor cord is
routed without contacting the rotating batten tube.
See Figure G. Install junction box cover.

15. INITIAL CURTAIN OPERATION
First, it is necessary to connect the power reel 4-prong plug to the mating receptacle located near the reel assembly. If the receptacle has
not been installed, an electric operation test kit (02080-PWR) is available from Porter. Next, remove the yellow plastic limit switch cover
and push the torque motor limit switches in the down and locked position. See Figure H. Refer to the specific counter-torque style for the
operational test procedure.
Caution: Until the torque motor limits are set, caution must be exercised when operating the curtain.

Wall Guide (No. 2081 Single Motor Curtains Only)
The wall guide track must be installed and positioned as described in step # 9. Before proceeding with the test, the motor torque bracket
must be connected to the torque motor. Insert the wall guide assembly rollers into wall guide track through the open end at the bottom of
the track. Slide the assembly up the track until the assembly is in line with the motor and batten tube. Loosen the spring ring clamp on the
motor mount assembly. Align the motor mount bracket pattern with the pattern on the motor head. If the bracket will not mate with the
motor head, the torque motor must be energized briefly for proper alignment. This will require a very short key switch actuation (or with
test box assembly).
Caution: Do not operate the motor for more than one second without torque bracket installed. Damage to the
motor and wiring will result.
Install wall guide torque bracket by pushing the motor head along with the batten tube into the bracket until
the spring ring clamp snaps into the motor head grooves. Tighten the spring ring clamp. See Figure I. Next, operate the curtain in the
“up” direction. The direction of rotation is not important with the wall guide counter-torque system. The curtain is now ready for limit
switch setting. Refer to the limit switch setting section.
