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 Timer-
To-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-To-
Close 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-To-
Close, 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.
