3.2.1 Automatic Emergency Deactivation Due to Timeout
If the door does not open or close within the
TIMEOUT
period, the control system
switches to
ERROR
mode and automatically depressurizes the pneumatic system, leav-
ing the door forceless. This deactivation prevents a situation in which the operator's
hands are caught between the chamber and the door and the operator cannot reach
for the push-button switch unit.
Typically, the following reasons can prevent the door from opening or closing within the
timeout period:
●
If the door speed is set too low, adjust it to match the timeout value; see Chap-
ter 6.8, "Adjusting the Door Speed" , on page 40.
●
If the
TIMEOUT
value is set too low, adjust it to match the door speed; see
TIMEOUT:<seconds>
on page 53.
●
If an obstacle is in the door's way, proceed as below:
To reactivate the chamber
1. Remove any obstacle out of the door's way.
2. Disconnect the 24 V DC power supply unit from the chamber.
3. Reactivate the chamber as described in Chapter 7.1, "Activating the Chamber" ,
on page 42.
You can verify proper functioning of the door's soft-close mechanism as described in
Chapter 6.6, "Testing Safety Systems" , on page 37.
