Function Expansion Unit FE260
18 Elster-Instromet GmbH
4 Initial operation
For initial operation the following steps should be carried out:
4.1 Power supply
•
Once all cables are connected and the housing firmly closed, switch on the FE260
power supply (mains voltage for the "AC" versions).
•
Check the “Power” signal lamp on the cover of the FE260. A continuous green signal
indicates that the FE260 power supply is functioning correctly.
•
Check the power supply of the connected volume corrector by bringing the status
messages into the volume corrector display. If the message “Batt. operat” (message
"15" in status "St.SY") is not entered here, the volume corrector is being supplied from
the FE260.
If the volume corrector displays the message "Batt. operat" (message "15" in "St.SY",
the volume corrector is not being supplied from the FE260. In this case check that the
intrinsically safe electrical circuits are connected correctly.
Only the "DC" version (not the "AC" versions) have the possibility of monitoring the supply
voltage on the terminal "10...30V". When a voltage limit is undercut, the connected volume
corrector receives a corresponding signal through the "DE3" terminal, setting the status
message "8" in the status "St.3" of the volume corrector. Due to this status signal, the
volume corrector can for example, with appropriate parameterisation, then activate an
output or execute another event-controlled action.
If you would like to use the voltage monitoring of the "DC" version, carry out the following
steps:
•
Set the voltage limit with jumper "ST5" (
→
Fig. 3, page 8) appropriate to your power
supply:
- to the position "12" for power supply with a nominal voltage of 12 V
(The limit for the warning is then approx. 11 V.)
- to the position "24" for power supply with a nominal voltage of 24 V
(The limit for the warning is then approx. 20 V.)
•
Make sure also that the terminal "DE3" is connected to the terminal of the same name
on the volume corrector. (
→
3.3.2 Terminal diagram, page 13).
•
On the volume corrector set the value "MdME3" (in the display column "Inp.") to "3".
•
If the monitoring does not function, also check the following values in the display
column "Inp." on the volume corrector:
- SC.I3 = 0003:228_0 ("St.E3")
- L1.I3 = 1
- SpI3
= 0.08_03:1.1 ("I3 Warn.sig
