5.1 Normal operation
The door opens and closes pneumatically.
5.2 Operation under increased temperature
Maximum allowed temperature, see product data sheet.
5.3 Behavior in case of air pressure drop
See product data sheet.
L-movement requires initializing of compressed air system. The door
command must be set to open at first. This will pressurize the pneumatic
system and ensure the proper L-movement during the following closing
cycles.
Proper function of internal nonreturn valve depends on speed of air pressure
drop. Slow pressure drop in air supply will not trigger the nonreturn valve,
therefore the position of the door will be undefined at loss of compressed air
pressure.
1. Open the door.
2. Close the door.
5.4 Behavior in case of power failure
Depending on customer’s installation.
