FE260

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."
•
If the monitoring does not function, also check the following values in the display column "Inp." on the
volume corrector:
SC.I3 2 = 0003:228_0 ("St.I3")
-
-
L1.I3 = 1
-
SpI3 = 0.08_03:1.1 ("I3 Warn.sig↑")
