4. Door Operation Principles
Full-close/full-open
relay
These
relays
provide
check
signals
when
the
door
is fully
closed
or fully opened.
These
signals
operate
indicators
or buzzers.
Conventional
electrically-driven
door operators
detect the door stroke or braking position with position sensor switches. The Daihatsu
Microprocessor-controlled
Door Operator counts the number of pulses from the motor, and
memorizes
it
as the door stroke. Based on this, the operator adjusts the braking position
and half-open position. This eliminates the necessity of position sensor switches and
manual of braking adjustments,
etc.
Operating principles of the Daihatsu Microprocessor-controlled
Door Operator.
"
.. Teaching (determining door stroke)
a.
About 3 seconds after the power switch
is turned
ON,
the
open
door starts to
close at low
speed and finally presses against.
the door frame to
close completely.
If the door is
fully-
closed when the power switch is turned on, the door is press-closed
3 seconds after
the power
ON.
b.
Upon receipt of the first ON signal from the sensor switch,
the Operator
opens the
door to about 70% of the door stroke at high speed, then brakes it to low speed
until the door reaches the fully open position.
c.
After the time preset on the open timer has expired,
the operator
closes the door at
high speed, brakes
it
just before the fully closed position,
and runs
it
at low
speed until the door closes completely.
This is one cycle of the door stroke teaching process.
Now the door stroke is stored
in memory.
This memory is cleared every time the power switch is turned OFF.
2. Normal door operation
When the teaching process is completed, the door starts to operate
in the normal manner.
