CONTROL WIRING
Radio Controls
On all models with type B2 control wiring, a terminal
bracket marked R1 R2 R3 is located on the outside of
the electrical enclosure. All standard radio control
receivers (single channel residential type) may be
mounted to this bracket. The operator will then open
a fully closed door, close a fully open door, and
reverse a closing door from the radio transmitter.
However, for complete door control from a
transmitter, a commercial three-channel radio set
(with connections for OPEN/CLOSE/STOP) is
recommended.
Additional Access Control Equipment
Locate any additional access control equipment as desired (but so that the door will be in clear sight of the
person operating the equipment), and connect to the terminal block in the electrical enclosure as shown on the
FIELD WIRING CONNECTIONS diagram. Any control with a normally (N.O.) isolated output contact may be
connected in parallel with the OPEN button. More than one device may be connected in this manner. Use 16
gauge wire or larger for all controls. DO NOT USE THE CONTROL CIRCUIT TRANSFORMER (24VAC) IN THE
OPERATOR TO POWER ANY ACCESS CONTROL EQUIPMENT OTHER THAN A STANDARD RESIDENTIAL
TYPE RADIO RECEIVER.
External Interlock Switch
The operator has a terminal connection for an external interlock switch. This switch must be a normally closed
(N.C.) two-wire device with a contact rating of at least 3 amps @ 24VAC. When such a switch is connected as
shown on the FIELD WIRING CONNECTIONS diagram, the control circuit will be disabled when the switch is
actuated, thereby preventing electrical operation of the door from the control devices.
WARNING
CAUTION
WARNING
WARNING
DO NOT USE RADIO CONTROLS WITH YOUR
OPERATOR UNLESS YOU HAVE INSTALLED
SOME TYPE OF ENTRAPMENT PROTECTION
DEVICE. THE USE OF RADIO CONTROLS
PRESENTS POTENTIAL HAZARDS DUE TO THE
USER’S ABILITY TO OPEN OR CLOSE THE
DOOR WHEN OUT OF SIGHT OF THE DOOR. IN
ADDITION, IF A SINGLE CHANNEL CONTROL IS
USED, THE USER WILL NOT BE ABLE TO STOP
THE DOOR FROM THE TRANSMITTER.
CLUTCH ADJUSTMENT
1.
Remove cotterpin from nut on the clutch shaft.
2.
Back off clutch nut until there is very little tension
on the clutch spring.
3.
Tighten clutch nut gradually until there is just
enough tension to permit the operator to move the
door smoothly but to allow the clutch to slip if the door
is obstructed. When the clutch is properly adjusted, it
should generally be possible to stop the door by hand
during travel.
4.
Reinstall Cotterpin.

AUXILIARY REVERSE SYSTEM
This operator has A.R.S., an auxiliary reverse system
to protect the door operator and its components. This
circuit recognizes change in speed of door in the
down direction caused by binding or obstructions.
Upon detection, the door will stop and return to fully
open position.
WARNING
CAUTION
WARNING
WARNING
THIS OPERATOR CONTAINS AN AUXILIARY
REVERSE SYSTEM THAT REQUIRES PROPER
CLUTCH ADJUSTMENT IN ORDER TO
FUNCTION. AN IMPROPERLY ADJUSTED
CLUTCH MAY REDUCE THE LIFE OF THE
OPERATOR OR ITS COMPONENTS.
The Auxiliary Reverse System (A.R.S.) is NOT
intended and may not be used as an entrapment
protection device. A safety reversing edge or
infrared sensor should be added to door if
necessary.
