Automatic operation with incomplete setup:
If the gate has not yet been completely set u
p or if the control system‘s reference run has not
yet been concluded, the control system run in a special safety mode (example: The gate‘s end
positions have not yet been detected in the reference run).
The gate then only moves at a slower speed. The automatic speed is not used until after the test
run with slow speed.
Even if the drive unit was electrically voltage-free, the gate only moves at slow speed at first until
an end position has been reached.
3.4.3 Automatic change of the operating modes
In the event of the failure of electronic safety devices on the gate (e.g. defective safety edge or
light barrier), the control system can automatically switch from automatic operation to deadman
operation. This automatic change is only made for an initiated motor movement and only in the
event of activation of the button intended for deadman operation. Subsequently, the control
system reassumes automatic operation; however, it can switch back to deadman operation in the
event of a renewed or persistent defect during the next run.
A change between the operating modes is possible in the following directions:
Automatic operation
deadman operation
Deadman operation
automatic operation (if safety has been re-established)
3.5 Connectable auxiliary equipment
The gate control system can be operated with one or more of the following components:
Safety contact edges
Safety contact edges with an 8.2-kOhm load resistance for the
open and close direction can be connected directly over clamping
units (Image 1: General view no. 10).
ISK-System
The control unit already contains the control and evaluation logic for
the inductive safety system ISK for the monitoring of travelling
safety contact edges (8.2 kOhm).
The INDUS onboard 70-757 is attached to the control system for
this purpose (figure 1: General view No.12. On a terminal (figure1
General view No.11) you can directly connect the immobile core
SPK 55.
Light barriers
One-way light barriers or reflected-light barriers can be connected
on a separate input (figure 1: General view No. 11).
