LOGIC BOARD LED OVERVIEW

NOTE: Before programming the logic board, set the operator’s open and close limits. LEDs on the logic board are provided to assist setting the limits. As each limit is activated the corresponding LED will light up. The abbreviations are Open Limit Switch (OLS), Close Limit Switch (CLS) and Sensing Limit Switch (SLS). Refer to page 19 for limit switch adjustment instructions.

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 (i.e., STOP, 24Vdc, limit LED(s) if limit(s) is 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.

LOGIC BOARD PUSH BUTTONS (OPEN, CLOSE, STOP)

Open, Close and Stop buttons are mounted directly on the logic board. Thus, making it easy to program as well as have door control at the electrical box.

Either the stop control or a jumper MUST be wired between terminals 4 and 5 for the on board push buttons to function.

DETERMINE AND SET WIRING TYPE

Read the descriptions of the different wiring types to determine which setting will be correct for each application. Once the wiring type is determined, set the selector dial accordingly.

LIFTMASTER MONITORED ENTRAPMENT PROTECTION (LMEP) DEVICE IS REQUIRED

A LiftMaster Entrapment Protection (LMEP) device is required for the following wiring types.

B2 Momentary contact to open, close and stop, plus wiring for

sensing device to reverse and auxiliary devices to open and close with open override. Programmable mid stop available with this wiring type. Compatible with 3-Button Station,

1-Button Station, 1 and 3-Button Remote Control.

TS (TIMER SECURE)

This mode will attempt to close the door from any position

except when fully closed, or when a safety input is present. The stop button will not disable the Timer-To-Close at any position. To disable the Timer-To-Close in this mode, installation of a defeat switch is required (see wiring diagram).

Momentary contact to open, close, and stop with open

override and Timer-To-Close. Every device that causes door to open, including a reversing device, activates the TimerTo-Close. Auxiliary controls can be connected to open input to activate the Timer-To-Close. If the timer has been activated, the open button and radio control can recycle the timer. The Timer-To-Close will function from the programmable mid stop with this wiring type. Compatible

with 3-Button Station, 1-Button Station and 1 and 3-Button Remote Control.

NOTE: A Programmable “Car Dealer Mode” available.

T Momentary contact to open, close, and stop, with open

override and Timer-To-Close. Every device that causes the door to open, except any safety edge input device, activates the Timer-To-Close. Auxiliary controls can be connected to open input to activate the Timer-To-Close. If the Timer-ToClose has been activated, the open button and radio control can recycle the timer. The stop button will deactivate the timer until the next command input. The Timer-To-Close will function from the programmable mid stop with this wiring type. Compatible with 3-Button Station,1-Button Station and 1 and 3-Button Remote Control.

NOTE: Programmable “Car Dealer Mode” available.

FSTS Momentary button contact for open, close and stop

programming. User set mid stop. User set Timer-To-Close. The single button station opens the door to the full open limit bypassing the mid stop and activates the Timer-ToClose, putting the operator in TS mode until the door reaches the down limit, or is stopped in travel. At which time the operator enters the B2 mode.

Compatible with 3-Button Station, 1-Button Station, 1 and

3-Button Remote Control. A 1-Button remote control in

FSTS mode will open only with the Timer-To-Close, bypassing a programmed mid stop. The Timer-To-Close will reset and reverse when closing.

LIFTMASTER MONITORED ENTRAPMENT PROTECTION (LMEP) DEVICE IS RECOMMENDED

A LiftMaster Entrapment Protection (LMEP) device is recommended for the following wiring types.

C2 Momentary contact to open and stop with constant pressure

to close, open override plus wiring for sensing device to reverse. Programmable mid stop available with this wiring type. Compatible with 3-Button Station and 1-Button

Station.

E2 Momentary contact to open with override and constant

pressure to close. Release of close button will cause door to reverse (roll-back feature) plus wiring for sensing device to reverse. Compatible with 3-Button Station.

D1 Constant pressure to open and close with wiring for sensing

device to stop. Compatible with 2 or 3-Button Station.

SELECTOR DIAL

IMPORTANT NOTES:

1. External interlocks may be used with all functional modes.

2. Auxiliary devices are any devices that have only dry contacts. Examples: photocell, loop detector, pneumatic or electrical treadles, radio controls, one button stations, pull cords, etc.

3. Open override means that the door may be reversed while closing by activating an opening device without the need to use the stop button first.

4. When the door is in a stopped position other than fully closed, and a safety input is activated (LMEP or EDGE), the Restricted Close (RC) feature will allow a close command when the close button is pressed and held. The operator will begin closing after 5 seconds. If the close button is released the door will stop.

When in E2 mode, the door will move to the fully open position.
