7.7.5 Partial Opening Motor 1
Partial opening Motor 1 only gives you the ability to open active leaf to a pre-set
value only.

movement. If a Pd command is executed from a complete OPEN position, the gate
will close.
An Open or transmitter command will always override the Pd command.

7.7.6 Delay Motor 2 in Open Direction

Delay Motor 2 in OPEN direction function defines time delay for Motor 2 in OPEN
direction. Not available for single motor application.
Not executed during reversal or after IR beam interruption in both directions.
no delay (both wings start opening at the same time)
1 second
2 seconds (Default)
3 seconds
4 seconds

7.7.7 Delay Motor 1 in Close Direction

Delay Motor 1 in CLOSE direction function defines time delay for Motor 1 in
CLOSE direction. Not available for the single motor application.
Not executed during reversal or after IR beam interruption in both directions.
no delay (both wings start in the same time)
1 second
2 seconds (Default)
... ... seconds
20 seconds

7.7.8 Timer To Close

Timer to close (TTC) function enables automatic closing of the gate from a com-
plete OPEN position after a pre-set period of time. Minimum one pair of LiftMaster
Infrared Photocells (IR) has to be installed to monitor closing movement to enable
TTC operation. TTC will not work if IR are protecting opening movement only.
TTC will also work with activated partial opening. If TTC function is active, timer is
counting down, and the IR beams are interrupted, the TTC timer shall re-start.
TTC not active (Default)
10 seconds
20 seconds
30 seconds
45 seconds

7.7.9 Reversal Time after Impact

Reversal time after impact function defines reversal behavior after obstacle obst-
ruction during closing or opening movement. This reversal behavior is valid both for
motor force detection and safety edge application.
2 seconds reversal and Stop
Reversal back up to the end limit position (Default)
During Closing movement, upon impact gate reverses up to Open
position. During Opening movement, upon impact gate reverses for
2 seconds and stops

7.7.10 E-Lock / Mag-Lock Settings

E-Lock function defines e-lock/mag-lock behavior.
24VDC – 500mA e-lock or mag-lock can be connected.
e-lock/mag-lock not installed (Default)
e-lock active for 1 second prior to Motor 1 start in Open direction
e-lock active for 2 seconds prior to Motor 1 start in Open direction
Magnetic lock, constantly active at gate CLOSED, constantly
inactive during OPEN and CLOSE movement, gate OPEN or STOP
position. Magnetic lock will be deactivated in Battery Back-up mode.
