CONTROL WIRING (con’t)

Radio ControlsOn all models with type C2 control wiring, a terminalbracket marked R1 R2 R3 is located on the outside ofthe electrical enclosure. All standard radio controlreceivers (single channel residential type) may bemounted to this bracket. The operator will then opena fully closed door, close a fully open door, andreverse a closing door from the radio transmitter.However, for complete door control from atransmitter, a commercial three-channel radio set(with connections for OPEN/CLOSE/STOP) isrecommended.

Additional Access Control EquipmentLocate any additional access control equipment as desired (but so that the door will be in clear sight of theperson operating the equipment), and connect to the terminal block in the electrical enclosure as shown on theFIELD WIRING CONNECTIONS diagram. Any control with a normally (N.O.) isolated output contact may beconnected in parallel with the OPEN button. More than one device may be connected in this manner. Use 16gauge wire or larger for all controls. DO NOT USE THE CONTROL CIRCUIT TRANSFORMER (24VAC) IN THEOPERATOR TO POWER ANY ACCESS CONTROL EQUIPMENT OTHER THAN A STANDARD RESIDENTIALTYPE RADIO RECEIVER.

External Interlock SwitchThe 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 asshown on the FIELD WIRING CONNECTIONS diagram, the control circuit will be disabled when the switch isactuated, thereby preventing electrical operation of the door from the control devices.

WARNING

CAUTION

WARNING

WARNING

DO NOT USE RADIO CONTROLS WITH YOUROPERATOR UNLESS YOU HAVE INSTALLEDSOME TYPE OF ENTRAPMENT PROTECTIONDEVICE. THE USE OF RADIO CONTROLSPRESENTS POTENTIAL HAZARDS DUE TO THEUSER’S ABILITY TO OPEN OR CLOSE THEDOOR WHEN OUT OF SIGHT OF THE DOOR. INADDITION, IF A SINGLE CHANNEL CONTROL ISUSED, THE USER WILL NOT BE ABLE TO STOPTHE 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 tensionon the clutch spring.
