This QuickStart is intended to highlight a single gate/door application. Each application is unique and it is the responsibility of the purchaser, installer and end user to ensure that the total gate/door system is installed and operated properly. Refer to the installation manual for complete information regarding installation, testing, and programming.

Install Monitored Entrapment Protection Device
This operator contains an inherent (internal) entrapment protection system and REQUIRES the addition of a LiftMaster external monitored entrapment protection system (non-contact photoelectric sensor or contact edge sensor) for EACH entrapment zone prior to gate movement. System includes six monitored entrapment protection inputs capable of covering all entrapment zones. Refer to the manual for complete information.
WIRING AND ADJUSTMENTS
Connect Power Wiring and Earth Ground Rod
Turn off the AC power from the main power source circuit breaker. Connect the earth ground rod, incoming power, and batteries (see images below). The operator can be wired for 120 or 240 Vac by choosing the desired power wiring socket on the
EMI board. Refer to your manual for complete wiring information.
Set Open Speed
The HCTDCU provides a high speed open option to help flow in high traffic areas. Select the open speed using the BIPART
DELAY switch.
BIPART DELAY OFF (default) = 8 in./sec. open speed
BIPART DELAY ON (fast) = 11 in./sec. open speed
Perform the Obstruction Test
1. Open and close the gate/door with the TEST BUTTONS, ensuring that the gate/door is stopping at the proper open and close limit positions.
2. Place a solid object under the open gate/door. Ensure that the gate/door, and the solid object can withstand the forces generated during this obstruction test.
3. Run the gate/door in the close direction. The gate/door should stop and reverse upon contact with the solid object. If the gate/ door does not reverse off the solid object, reduce the force setting by turning the force control slightly counter-clockwise.
The gate/door should have enough force to reach both the open and close limits, but MUST reverse after contact with a solid object.

Set the Limits and Force
INITIAL LIMITS AND FORCE ADJUSTMENT
1. Press and release the SET
OPEN and SET CLOSE buttons simultaneously to enter limit setting mode.
2. Press and hold one of the
MOVE GATE buttons to move the gate/door to the open or close limit.
3. Press and release the SET
CLOSE or SET OPEN button depending on which limit is being set.
4. Press and hold one of the
MOVE GATE buttons to move the gate/door to the other limit.
5. Press and release the SET
CLOSE or SET OPEN button depending on which limit is being set.
6. Cycle the gate/door open and close. This automatically sets the force.
When limits are set properly the operator will automatically exit limit setting mode.
FINE TUNE THE FORCE
The REVERSAL FORCE DIAL on the control board is used for fine tuning the force in cases where wind or environmental changes may affect the gate/door travel. Based on the length and weight of the gate/door it may be necessary to make additional force adjustments. The force setting should be high enough that the gate/door will not reverse by itself nor cause nuisance interruptions, but low enough to prevent serious injury to a person. The force setting is the same for both the open and close gate/door directions.
1. Open and close the gate/door with the TEST BUTTONS.
2. If the gate/door stops or reverses before reaching the fully open or closed position, increase the force by turning the force control slightly clockwise.
3. Perform the “Obstruction
Test” after every force setting adjustment.
Installation Checklist
Check the following before leaving the site:
Are all the wiring and connections tightly connected?
Is the AC power on? If the operator is left running on battery only, it will drain the battery and will result in a service call.
Check the batteries and battery connections. Make sure there are two
12V batteries. Replace batteries if depleted to less than 20V.
Remove the protective anti-scratch film from the photoelectric sensors. Leaving the film on can result in poor sensitivity as the film decays/yellows/peels.
Confirm whether the site should be fail safe or secure and set the operator accordingly.
Confirm operation of the following (if applicable):
Entrapment protection devices
Loops
TES relay
SOS/emergency transponders
Check operation of ALL legacy receivers using the MAX transmitter
Timer-to-Close setting
Quick close setting
Anti-tailgate setting
