User Manual for ComTroll 115C
indicators will also respond with information about whether the line voltage (or load current)
is above or below the set-point used by the indicator for trip and reset of the indicator.
The indicators will respond as follows:
a)
If the fault indicator DIP8 is OFF, the indicator cannot be remotely programmed. The
yellow and green LED (on the indicators) will flash simultaneously.
b)
If the fault indicator DIP8 is ON, the indicator is ready for remote programming. The
yellow and green LED (on the indicators) will flash alternating.
Point a) and b) will be indicated for 9 seconds.
c)
If the line voltage (or load current) is above the threshold for the indicator the green
LED on the indicator will flash.
d)
If the line voltage (or load current) is below the threshold for the indicator the yellow
LED on the indicator will flash.
Point c) and d) will be indicated for 3 minutes.
If the Collector does not get any feedback from one or more of the fault indicators, it will
close the communication failure relay output to indicate a problem with the communication.
2. Communication check and test of relay operation
Press
RESET REMOTE
for more than 2seconds but not longer than 4seconds until the Rx/Tx-
LED (yellow LED on the collector) is switched off.
Within maximum 12 seconds, all fault indicators should switch on both the yellow and green
LED (in the indicator). When the broadcast period is finished (12 seconds) the green LED will
be switched off.
The yellow LED in the indicator remains on for period of 10s + address-ID. (e.g in indicator
with address ‘7’ the yellow LED will be on for 17 seconds).
After this period the main indication LED (for permanent faults) will flash once and transmit a
fault message to the collector which will set a pulse on the corresponding relay output.
3. Uploading new settings in the fault indicators (remote programming)
To upload new settings for the fault indicators, SW2 DIP 1 -7 is used. These switches “mirror”
the setting in the LineTroll 110Eur and LineTroll 110Tur. See tables in section 3.3 for
programming details. Please note that DIP8 on the fault indicator must be ON to accept
remote uploading from the collector.
Press
RESET REMOTE
for more than 4sec until the Rx/Tx-LED (yellow) and the Running led
(green) starts flashing on the Collector.
