LCN Benchmark® AU9100 Series
Low Energy Operators
Installation Manual

LCN Low Energy Operators should be installed in accordance with the current Allegion LCN installation instructions.

Commissioning and Servicing of installed units must be carried out by an Allegion Approved, Authorised Technician

1 GENERAL

The LCN Benchmark® 9100 Series is an automatic electromechanical swing door operator for use on hinged, centre pivoted, and offset pivoted doors. The controller is a microprocessor based system, tracking the door position at any time during the cycle. When activated the Benchmark® 9100 drives the door to the full open position creating the potential energy in the spring. When closing the electrical power is reduced and the door closes by controlling the potential energy release in the spring force. The activating circuit opens the door from any position on the closing swing. During power failure the Benchmark® 9100 acts as a manual door closer (size 3). Door opening and closing cycles, including opening speed, back check speed, hold open time delay, closing speed, and latch position are all adjustable.

WARNING! Always disconnect main power to the operator prior to servicing or cleaning

Pull Arm

6.6 Adjust the arm
6.6.1 For pull systems, remove the locking screw from the arm
6.6.2 For the push system remove the locking screw from the arm

Adjust the arm

6.7 Keep the door in the full open position and adjust the arm length as necessary to align the door at 90 degrees from closed. When the arm is adjusted to the correct length, tighten up the 8mm socket head screw that secures the arm to the operator spindle and ensure this is secure, then tighten the arm locking screw
6.8 Turn off the power operator switch. The door closes

6.13 Install the cover assembly on the operator
6.14 Release the operator for service ( see “Release for Service” on page 14)

7 OPERATIONAL CHECK

7.1 Set the Key switch to Auto (1 Way) and turn on the operator power switch
7.2 Activate the operator using the activation device, the operator will perform one sizing cycle
Sizing cycle: Occurs after a legitimate activation signal is received, after power has been turned on. During the size cycle, the door opens and closes one time.
7.2.1 If the door does not open at all during sizing cycle
7.2.2 Check door for binding
7.2.3 If an electromechanical lock is being used, check that the lock disengages before the operator opens the door.
7.2.4 Check fuses, Circuit breakers, and connections.
7.2.5 Adjust the operator and check door operation (See “Operator Adjustment on page xx)

Opening speed 75%
Back check speed 75%
Hold open time delay Minimum
Latch position Maximum
Closing speed 50%
SW1, 2, 3, 4 OFF

If the door does not open fully during size cycle check the door for binds

Increase the back check speed slightly and check door operation continue increasing back check speed until door opens fully

7.3 If the door slams open decrease the back check speed slightly and check door operation. Continue decreasing back check speed until the door opens without slamming
7.4 After the sizing cycle is complete and the door is closed, apply a maintained activation signal and check that the door remains open while the signal is applied.
7.5 If a door safety device is being used:
7.6 Door open safety
When the door is in the closed position activate the safety device, then try to activate the door the door should remain closed.
Activate the door, as the door is opening activate the safety device the door should stop, and then slowly drive to the full open position.
7.7 Door close safety
Activate the door then maintain activation of the safety device, the door should open and remain open.
As the door is closing, activate the safety device, the door should re-open to the open position, time out and then close.
7.8 When the door is operating properly, continue with step 6.10 on page 9

8 OPERATOR ADJUSTMENT

See table below and diagrams on page 18 for operator feature adjustment. After adjustment, cycle the door
several times and check for proper operation, then continue with step 6.11 on page 9.

NOTE
Adjust operator for the slowest operation practical in accordance with the latest AS_5007 standards for powered doors for pedestrian access and egress.

Opening speed 5 sec’s or more

Closing speed 3 sec’s or more

9.2 Install all safety, traffic control, and instruction labels on the door as required by the latest AS_5007 Standard. Failure to do this leaves the installer LIABLE for any accident that might occur. This must be done.
9.3 Verbally instruct the owner or person in charge of the proper operation of the door.
9.4 Instruct the owner or person in charge to routinely inspect the door for the following

Occasional damage
Developing problems
Minor preventative maintenance

9.5 Instruct the owner or people in charge who and where to call for service and maintenance when required.

IMPORTANT
Make sure to install all safety, traffic control and instruction decals on the door as required

10.1 OPERATION

10.1.1 Sizing

From start up (size) the door will activate from morning entry (24Hrs,T9, T10) regardless of key switch position, 1 Way input (T27,T28) with key switch in one way. 2 Way input (22, T23) with key switch in two way, or key switch Hold Open. The first movement will be in the open direction – The speed of the sizing cycle is automatic and cannot be set from a potentiometer the door drives opened to the full open position where the system sets the counter to full open. The door closes at close speed then latch up to closed position where the system sets the counter for closed position. From these two parameters opened and closed position the system calculates all the other parameters it requires for normal operation i.e. latch position back check position etc.

Notes
If the encoder is connected for opposite direction or faulty or disconnected the door will operate erratically continuously opening ½ way closing latching and re-opening. This will continue to occur until power is switched off

10.1.2 Auto Reverse on open

The auto reverse open is set from the backcheck position pot. This sets the level of current required to trip the door as it is opening.

Normal operation
Key switch, activation, morning entry/fire alarm, locking, and safety.

10.1.3 Standard operation

Upon a legitimate activation signal the door accelerates up to open speed, monitoring the current load on the drive output. (If the current reaches a level above the set datum the door will stop and close). The door travels at the set speed (Potentiometer setting) until it reaches the set backcheck position, where the speed (Potentiometer setting) is decreased to back check speed. When the door stops at hold open position the system sets the hold open speed and holds the door open until activation and or timer is cleared. The door will then close at close speed, (Potentiometer setting) up to latch position (Potentiometer setting). Where the speed is decreased by driving the motor in the open direction (fixed setting), the power is set such that the spring will overcome this power and continue to allow the door to close up to the closed position. During the open cycle the safe opening (T1, T2) is active and the Safety side Adj Pot sets the angle at which the sensor is redundant, this can be set from Closed up to back check position. During the closing cycle the safe closing (T5, T6) is active and the Activate side Adj pot sets the angle the sensor is redundant, this can be set from Opened up to a few degrees of closed position.

General
24Hr operates the door regardless of key switch position the door will drive open and remain in the open position as long as the contact is made (Program 4 is the exception) Key switch position OFF no activation or safety operates. Electric lock operates when door closed dependant upon function selection Electric lock operation is set from the function selector the time delay is fixed Key switch Position 1 Way the activation from internal Activate (T27, T28) safety operates. Electric lock operates when door closed dependant upon function selection Key switch Position 2 way the activation from internal Activate (T27, T28) and external Activation (T22, T23) safety operates. Electric lock does not operate when door closed Key Switch H.O The door operates to the open position and remains in the open position safety is by passed (If safety activated the door will open slowly)
