(7.4) and (8.2). At "Start" the digital input to start the function is set, at "Stop/Inhibit" the digital input
to stop/inhibit the function is set. DIB extension module(s) are necessary.
By enabling the parameter „Hand-op. charge”
(9.1) a manual control of the default voltage
of the rectifiers is possible.
Enabling "System test“ (9.2): For the
config
uration please see the menu "System
test“ (section 6.10.10).
Enabling „Energy balance“ (9.3): The curre
nt
which is flown into the battery respectively is
withdrawn from the battery is accumulated,
the value (Ah) is shown on the display.
Measurement of the isolation resistance:
If the measurement of the insulation resistance "Isolat. measure" (9.4) is enable
d, the measuring source
is used which is defined as BU input at "Assignment Measu"
(see section 6.5.1), subitem "Isolation".
Additionally the UPC4 causes, that the assigned BU connects the half of the voltage value V1 via a high-
resistance resistive voltage divider by relay to the DIN rail. By differential measurement to this voltage it
is detected whether an insulation failure is present or not.
By parameter "Isol. by dig.inp" (9.5) isolation m
easurement can be disabled. That could be necessary if
isolation measurement must not happened due to an external action for a certain time (e.g. alternative
measurement enabled, system is maintained).
ATTENTION!
It is only permitted that only one BU measures per each ground. Otherwise an
inherent isolation error is generated.
Modem:
For the automatic initialization of an external modem, parameter (9.6) has
to be set to „1“. The modem
settings have to be done at "Modem
" (see section 6.10.6).
SNMP:
Parameter "SNMP Enable" (9.7) fade
s in the SNMP setting options which are enabled by this at the MMT.
Parameter (9.11) is not used to enable SNMP physically. SNMP is continuously enabled in the
background.
Lamp test: At (9.8) it is possib
le to enable a lamp test by digital input.
Capacity calculator:
Parameter "CapacityCal enab" (9.9) e
nables the capacity calculator. For detailed information please see
"Capacity calculator
" (section 6.10.4).
Field bus:
At "Fieldbus" (9.10) a fiel
d bus (Modbus) can be enabled. ProfiBus is currently not implemented.
