Model LGJ is a light-duty gear-reduced
jackshaft operator for rolling grilles and shutters. It features an
internal door lock sensing circuit, a compact design and a floor level
disconnect.
Standard Features
Motor:
Powerful 1/4 HP, 115V single phase motor with instant
reverse and internal automatic reset thermal overload. Removable without
affecting limit switch settings.
Wiring
Type: The Model LGJ is easily wired
for C2 or B2 wiring. The operator is pre-wired to accept a sensing device,
photoelectric control, radio controls and most types of access control
equipment.
Operator/Motor
Control: Solid State Circuit (G2)
with Door Lock Sensing Circuit (NEMA 1 enclosure).
Control
Circuit: 24V NEC Class 2.
Floor
Level Disconnect: Floor level disconnect
provides emergency manual operation.
Drive
Reduction: Heavy-duty wormgear-in-oil-bath
speed reducer.
Pushbutton
Station: 3-button station for OPEN/CLOSE/STOP
functions is standard for all operators. Controls with one, two and
three buttons are available.
Construction:
NEMA 1 Type electrical box with durable baked-on powder
coat finish. Easily converted for right or left mounting.
Door
Lock Sensing Circuit: The Model LGJ
includes a speed sensor in the electrical enclosure and a sensing circuit
which sends a signal to stop the motor if the door jams, such as would
be caused by failure to release the lockbar of a rolling grille before
starting the operator. In addition to stopping the motor, if the door
or grille is in fully closed position, it will drive the motor in the
opposite direction for approximately 1 inch of door travel. This releases
the pressure on the lockbar thus allowing the lock to be easily opened.
Control
Accessories and Options
Sensing
Edge: (Recommended) Designed to sense
an obstruction and signal door operator to stop or reverse as desired.
Either an electric or pneumatic sensing device can be added to bottom
edge of door.
Radio
Control: Universal transmitters and
receivers are available to signal the operator to open and/or close
door.
Emergency
Egress Device: Attractive faceplate
mounts flush on wall and contains handle to disconnect operator from
a grille, thereby allowing the grille to be opened manually or by spring
tension.
Rolling
Door Interlock Switch: Interlock switch
disables the operator control circuit when a manual door lock is engaged
preventing damage to the door and operator.
CPS® Commercial
Protector System: (Recommended) An inexpensive "non-contact"
photo safety sensor designed to sense an obstruction and signal the
door operator to reverse to open.
