Testing

TEST 3-BUTTON CONTROL STATION
1. Press OPEN button. (The door should move in the open

direction.)

2. Press STOP button. (The door should stop.)
3. Press and hold the CLOSE button. (The door should move in

the close direction.)

4. Release CLOSE button. Door should stop if in C2 or D1 mode.

Door will reverse to full open position in E2 mode. The door
should continue closing in all other modes.

5. Press STOP button. (The door should stop.)

TEST LIMIT ADJUSTMENT
1. Press OPEN button. (The door should open.)
2. Allow the door to fully open.
3. Press and hold the CLOSE button. (The door should close.)
4. Allow the door to fully close.
5. If the limits are not set properly, remove power and adjust

limits (refer to Limit Adjustment section).

TEST THE PHOTOELECTRIC SENSORS
1. Open the door.
2. Place an obstruction in the path of the photoelectric sensors.
The LMEP LED will blink on the logic board and the receiving
eye LED will turn off.
3. Press and hold the CLOSE button.
The door should not close if photoelectric sensors are

installed.

4. Remove the obstruction.
5. Press and hold the CLOSE button. Door should close.
If door did not reverse from obstruction, check
photoelectric

sensors.

NOTE: The Logic 4 control board will automatically learn the
photoelectric sensors (LMEP) once they are properly connected.
If the LMEP is misaligned or disconnected the LMEP LED on the
logic control board will blink on and off. You can close the door
by entering the Restricted Close (RC) mode by holding the close
button. The operator will begin closing after 5 seconds and will
continue to close to the Close Limit or when the close button is
released.

To unlearn the photoelectric sensors, turn the selector dial to
DIAG, push and hold the stop button until the MAS LED flashes.
Without the photoelectric sensors connected the only mode of
operation will be C2, D1 or E2.

IMPORTANT NOTES:

• Do not leave power to the operator 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 how
to manually disconnect the door from the operator.

TESTING

To avoid SERIOUS personal INJURY or DEATH:
• Disconnect electric power BEFORE performing ANY

adjustments or maintenance.

• ALL maintenance MUST be performed by a trained door

systems technician.

Apply power to the operator.

When power is applied to the operator, the following LED’s will
illuminate: STOP, CLOSE, OPEN, LMEP, 24Vac, RADIO, DATA,
TIMER ENABLE, OLS MID, SLS, CLS, and MAS. Once the power
up process is completed (approximately 2-3 seconds) only the
appropriate LED’s will continue to be lit:

• Between limits: 24Vac and STOP

• Fully closed position: 24Vac, STOP, CLS and SLS

• Fully opened position: 24Vac, STOP and OLS

Additional LED’s will light when device(s) are activated.

NOTE: When the power up process is over, the MAS LED will
blink a code indicating the version of firmware. If the selector dial
is in the DIAG, OPTN, or PROG position, the MAS will not provide
this code. After the code has been provided the MAS LED will go
out.

1. After power is connected to the operator, the green indicator

lights in both the sending and receiving sensors will glow
steadily if wiring connections and alignment are correct.

2. If the green indicator lights are fl ashing rapidly (and the

invisible light beam path is not obstructed), alignment is
required:

Loosen the receiving sensor wing nut to allow slight rotation of
the sensor. Adjust sensor vertically and/or horizontally until the
green indicator light glows steadily.

• When the indicator lights are glowing in both sensors, tighten

the receiving sensor wing nut.
