Fig. 48. Excel 500 CPU module front panel
The operator interface on the front of the CPU modules
allows connection of the Xl581/XI582 Operator Interface or
the XL-Online PC MMI. As an option, the XI582 can be
connected at the rear of the XC5010C. When connecting at
the rear, the switch on the front panel of the XC5010C must
be set to "Rear".
XP502 Power Supply Module
Fig. 49 shows the pin-out of the XP502 Power Supply
module.
Fig. 49. XP502 Power supply module and watchdog
circuit
To monitor the line power supply, the watchdog alarm must
be provided with its own power or battery supply.
Controller in operation: Watchdog relay terminals 17 and 18
connected.
Controller non-operational: Watchdog relay terminals 16
and 17 connected.
RIN-APU24 Uninterruptable Power Supply
The RIN-APU24 Uninterruptable Power Supply can be wired
to an XP502 in order to power XC5010C/XC6010 controllers.
In this context, a distinction must be made between the
following three different possible cases:
wiring of the RIN-APU24 to an XP502 powering
XC5010C/XC6010 controllers equipped with internal
modules, but not connected to Distributed I/O's;
wiring of the RIN-APU24 to an XP502 powering
XC5010C controllers connected to Distributed I/O's, but
not equipped with internal modules; and
wiring of the RIN-APU24 to an XP502 powering
XC5010C controllers equipped with internal modules and
connected with Distributed I/O's.
Further, in the case of the XCL5010, the RIN-APU24 can
provide power directly (i.e. without recourse to an XP502). In
this case, no distinction need be made between controllers
with (or without) internal modules and/or connected (or not
connected) to Distributed I/O's.
