3.2 Modes of operation
After installation and initial operation, the motor control device is ready to use.
The door drive starts to move, when the potential free inputs (Terminals 7, 9 and 10)
are triggered.
The following modes of operation are possible:
•
Dead man's control:
The drive moves in the desired direction, as long as the corresponding input
signal is applied and no obstruction is detected. Otherwise it stops instantly.
•
Semi-automatic mode:
The drive moves in the desired direction after a trigger impulse on the
corresponding input signal. After an opening command, it will stay open until a
close command is applied.
When an obstruction is detected or a stop signal or a command contrary to the
driving direction is applied, the drive stops.
•
Automatic mode:
Additional to the semi-automatic behavior, the door closes automatically, when
a close delay time is over.
When an obstruction is detected during closing, the drive reverses and remains
open for the close delay time again.
If a command contrary to the driving direction is applied, the drive reverses. On
a stop signal, the drive will stop as long as the stop input is active. After the
stop signal is released, the drive continues its operation.
3.3 Features
The motor control device supervises the motor current during operation. In case of
an obstruction the motor current will raise, which is detected by the motor control
device. In this case, the motor control device stops the motor.
During initial operation, the control device measures the duration of a normal cycle.
A short time before the wing reaches the end, the motor slows down. This reduces
mechanical wear and increases safety.
In automatic operation mode, a close delay time can be set via the potentiometer
P1. The delay time can be set in a range of 5...60 seconds.
Some special features need speed measurement, which is provided by using a
motor with encoder. The motor control device detects a connected encoder during
initial operation and activates the special features.
The motor control device provides a permanent 24 V DC output for supplying
external components. Its maximum current rating is 250 mA.
For some applications extra I/O may be needed. In this case, the special input and
output terminals of the motor control box can be useful. The motor control box
provides two configurable inputs, one configurable 24 V DC output and optionally
two potential free relay outputs. For configuration of special functions or application
examples, please contact the manufacturer.
