DETERMINE WIRING TYPE
Refer to the wiring diagram located on the inside cover the electrical box to determine the type of control wiring.
Standard C2 or B2 Wiring
Standard operators are shipped from the factory with
jumper set for C2 wiring, which requires constant
pressure on button to close the door. If momentar y
contact on close direction is desired (B2 wiring) you
must include an entrapment protection device. See
close control jumper setting below.
Constant pressure on close (C2 wiring)
Red jumper wire was placed on terminal #2 in
electrical enclosure. The operator will require
constant pressure on close control in order to keep
door moving in the close direction.
Momentary contact on close (B2 wiring)
Move red jumper wire from terminal #2 to terminal
#3. The operator will require only momentary
contact to close the door.
SPECIAL CONTROL WIRING
If your operator was shipped from the factory with
non-standard control wiring or with optional
accessories that require addition instructions, refer to
the wiring diagram(s) indicated in the special control
wiring data box. When a replacement wiring diagram
is present, wiring diagrams in this manual will not
apply. Refer only to the replacement wiring diagram
for all connections.
IMPORTANT NOTE: If your wiring diagram is
missing, or you are unsure of the wiring type for
your operator, contact the customer service
department @ 1-800-528-2806.
LOCATING THE CONTROL STATION
All operators are supplied with some type of control station. Generally a three button station
(OPEN/CLOSE/STOP) is provided. A two-position key switch or control station (OPEN/CLOSE) may be added or
substituted when requested at the time of order. Mount the control station near the door.

CONTROL WIRING (con’t)THREE PHASE SCHEMATIC DIAGRAM
Radio Controls
On all models with type B2 control wiring, a terminal
block marked R1 R2 R3 is located in the inside of the
electrical enclosure. All standard radio control
receivers may be used. 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 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
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.

NOTICE:
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.
The operator has been pre-wired to accept
connection of a reversing edge device. Connect the
normally open contacts to terminals T4 and T8 on the
low voltage terminal block. A cut-off switch will deactivate the safety device during the last few inches of
the door's downward travel.
TEST THE SYSTEM
Turn on power. Test all controls and safety devices to
make sure they are working properly. It will be
necessary to refer back to page 6 for fine adjustment
of the limit switches.
IMPORTANT NOTES:
Do not leave operator power on unless all safety
and entrapment protection devices have been
tested and are working properly.
Be sure you have read and understand all Safety
Instructions included in this manual.
Be sure the owner or person(s) responsible for
operation of the door have read and understand
the Safety Instructions, know how to electrically
operate the door in a safe manner, and know how
to use the manual disconnect operation of the
