1. Features
High performance
• The DC motor remains cold during continuous
door operation.
• Quick opening and closing. Maximum
speed is 500 mm per second .
• The brushless
moulded motor and the completely
enclosed
reduction
gear are
silent, durable, and maintenance-free.
Multiple functions
• Half-open
Installing
the half-open
switch allows the door to open halfway.
The half-open
stroke can be adjusted
in 7 steps from 12.5% to 87.5% of the door stroke. The
Automatic/Oonstant
selector permits
selection between automatic
full/half-open
opening and fixed half-opening.
In the Automatic
setting, the door is opened
fully if the traffic is heavy
(in terms of frequency)
and halfway if it is
(\light. In the Constant
setting, the door is always opened halfway.
• Trouble detection
If a problem occurs with the door or the door drive system--e.g.
jammed door,
obstructed
door, or broken drive belt, the door operator detects it, shuts off
power to the motor, and generates
an alarm; there are different
alarms for
different
problems.
• Press-closing
When fully closed, the door presses against the frame, permitting
no gap.
• Emergency
door operation
Upon receipt of a signal from an emergency
sensor
(optional), the door operator
opens or closes the door to the full extent according
to the setting. With a 24-
VDC battery pack
(optional), this emergency
door operation
is available
in the
event of a power failure.
Automatic
adjustments
• Braking position
The braking position
is automatically
adjusted
to provide a constant braking
force regardless
of the door weight and door sliding resistance.
Safety
• Safe operation
If the door encounters
an obstacle on the opening stroke, the power supply to
the motor is shut off. When it is blocked on the closing stroke, it reverses to
the full-open position,
then starts to close at low speed again. If the door is
blocked again, it stops and sounds an alarm.
• Emergency
stop
Pressing an emergency
stop switch
(optional) stops the opening or closing door.
