Automatic full open
Automatic half open
Switched to 0 V via 2 diodes
z
Terminals 25 and 26
By short-circuiting the PSA connection during 2 seconds (terminals 25 and 26), a RESET can
be carried out with or without PSA.
z
Terminal 27
Stop (emergency stop 1)
If this input is interrupted:
* The motor speed is immediately reduced.
* The 5 V and 24 V supply is switched off ------ The sliding door is stopped.
If this input is closed:
* The sliding door closes slowly, and then will operates normally according to the program
switch position.
* The door reached the CLOSED position with PSA, LED32 flashing, and then it continues
to function normally according to the program switch position.
z
Emergency stop (X4 on drive unit)
If this input is cut off, the motor is immediately stopped and stands still. The door wings can
be moved by hand.
5.5 Interlock operation
Principles
z
Both installations must be plugged into respectively the same power supply;
z
Interlock function in program switch position Night and Exit (locked);
z
In order to guarantee the interlock function, both program switches must be in the same
position;
z
However, the communication via the interlock connection functions in any position of the
program switch. This means that doors, which are not in a locked program switch position,
are capable of blocking other doors, which are in a locked program switch position.
Conversely, the pending signal is not taken into account.
z
Opening commands are memorized.
z
Memorization of the opening impulses can be suppressed by softswitch no. 16.
z
The EMERGENCY OPEN or EMERGENCY CLOSE function has priority.
z
If a door remains hooked in the locking mechanism, the other door is released after a short
delay time has expired.
z
Double openings are prevented by a special timing order arrangement, even if two opening
commands exist at the same time.
Procedure
Both doors are closed. The MASTER supplies a signal, which must be answered by the SLAVE;
otherwise the signal is repeated by the MASTER. If in the reverse case the MASTER fails to
respond, the SLAVE will repeat the request. If one of the doors is not CLOSED, it transmits a 0 V
signal to its interlock output. After a RESET or a mains failure the synchronization is always
made by the MASTER. This ensures that the setting-up procedure is carried out in accordance
