There is no door-open alarm – what is the reason for this?

   The TL-S5 does not offer this function.

The input at the I/O module does not operate.

   The inputs must be live. The opto-couplers operate at a voltage of 5-30 V DC.

The illuminated circle is red and the yellow LEDs flash without an audible alarm.

   A DCW component has been disabled or an address has been changed. Disconnect the power, hold the red pushbutton down, reinstate the power and release the pushbutton.

The illuminated circle on the terminal is green and a slow-beat audible alarm is sounding.

   a) The locking time has expired and the door is still open or is otherwise unable to lock. Or b) The lock is active but the red feedback signal wire (terminal 4) has been interrupted => check...

The illuminated circle on the terminal is red, the yellow LEDs flash and an audible alarm is sounding.

How is the control unit supplied with power?

I am unable to actuate the lock via In1 (X2).

What does a triple flash sequence on the SVP control unit mean?

How do I change the SVP 6xxx circuitry in order to engage or disengage the lever handle?

How can I modify the circuitry of the SVP-S 2x in order, for example, to switch to permanent-release during the day?

I have an SVPxxxx and the trip latch is incorrectly handed.

Can I operate the SVP2xxx without a control unit?

Can emergency exit sliding doors be locked at night?

Who can help me in the event of glass breakage?
