ALARM ON CABLE FAILURE (CABLE FAILURE)
The LED for "CABLE FAILURE" indicates the actual function as follows:
EITHER: RED CABLE FAILURE FUNCTION:
No alarm on cable breakage
OR: GREEN CABLE FAILURE FUNCTION:
Alarm on cable breakage
Pressing FUNCTION SELECT causes the indication/function to
change from one to the other. When the required function is
indicated, enter this into the programme memory by pressing
ENTER.
Pressing ENTER results in the next function in the order being
pointed to: time delay.
NOTE: A resistor (1kΩ) should be mounted across the
external alarm contact to obtain alarm on cable
failure (see connection diagram).
TIME DELAYED REGISTRATION OF AN ALARM CONDITION (DELAY OF
ALARM)
The LED for "DELAY OF ALARM" indicates the actual function as follows:
EITHER: RED DELAY OF ALARM FUNCTION:
Immediate registration of an alarm
condition
OR: GREEN DELAY OF ALARM FUNCTION:
Delayed registration of an alarm
condition
Pressing FUNCTION SELECT causes a change from one indication/function to the
other. When the required function is indicated, enter this into the programme memory by
pressing ENTER.
If immediate registration of an alarm condition was selected (i.e. LED for "DELAY OF
ALARM" is lit with red light), the programming of this input channel is hereby finished.
If so, you are back at the beginning of the programming routine, i.e. at selection of
channel (by means of CHANNEL SELECT) and the channel selector points to – i.e.
green light still
in the LED for – the channel for which the programming has just been
finished. This is made as it is easier to change a just entered but unwanted function of
the relevant channel.
