6. Functional check
6.1. Internal
6.1.1. [On] LED
The [On] LED lights up if the remote On/Off input is activated.
6.1.2. [Fault] LED
The [Fault] LED lights up (the [On] LED also lights up):
- if the bar is overloaded,
- in case of spark-over.
The [Fault] LED flashes quickly (the [On] LED also lights up):
- if the bar is overloaded repeatedly or continuously,
- in the event of repeated spark-over.
In the event of overloading or a spark-over, the bar will be switched off briefly.
Overloading can be caused by fouling or because the bar is mounted in the wrong place.
(See para. 4.3.) The bar remains switched off if it is repeatedly or continuously overloaded or if
repeated spark-over has occurred. The bar can be switched on again by removing the control
voltage at the remote On/Off contacts (pins 2 and 5) for at least one second before applying it
again. The bar can also be switched back on by switching off the supply voltage for a few
seconds.
6.2. Indication of pulse frequency switch position with [Fault] LED and [ON] LED
After the 24 V DC supply voltage is switched on, the [Fault] LED and [On] LED are used to
indicate the position of the pulse frequency switch. This works as follows:
- the red [Fault] LED flashes 10 times quickly.
- the yellow [On] LED flashes slowly. The number of flashes corresponds to the position
of the switch (0 to 9 flashes).
- the red [Fault] LED flashes 10 times quickly.
After the pulse frequency has been displayed, the [On] LED lights up again (Remote = ON).
If the switch for the pulse frequency is turned during operation, the pulse frequency will also be
indicated as described above.
During indication of the pulse frequency using the [Fault] LED and [On] LED, a high voltage is
present on the emitters. If a fault occurs during indication of the pulse frequency, the [Fault] LED
lights up and the pulse frequency indication is turned off.
6.3. External: Bar operating OK function
The external Bar operating OK output is active if the following three conditions are met:
the supply voltage is present on pins 1 and 6,
the bar is activated via pins 2 and 5 (remote On/Off contact),
there is no fault (see para. 6.1.2.).
