Troubleshooting
Operating anomalies
AC-power problem
The green lights on the communications
cards and the acquisition card are all off:
◗ check the position of the input voltage
selector (see figure 3),
◗ check that the power cable is properly
connected (see figure 4),
◗ check the fuse and replace it if necessary
(see below "fuse replacement").
Communications problem
The green lights on the communications
cards flash regularly every second for more
than one minute:
◗ check the connection between the
MultiSlot module and the UPS (see figures
7, 8 and 11),
◗ check that the cards are correctly installed
in the MultiSlot module,
◗ press the reset button on each card
installed in the MultiSlot module,
◗ if necessary, deenergize and reenergize
the MultiSlot module.
Fuse replacement
The MultiSlot module is protected by a fuse.
If the fuse blows, it must be replaced, as
shown in figure 13.
The replacement fuse must imperatively
have the same characteristics as the original
fuse (500 mA, 250V, delayed).
A replacement fuse is supplied with the
MultiSlot module.
If the problem continues, contact our
after-sales support department.
Card start-up problem
The green light on a communications card
remains on or off:
◗ check that the card is correctly installed in
the MultiSlot module,
◗ press the reset button of the faulty card.
Invalid installation

invalid:
◗ MultiSlot module not connected to a UPS
(no U-Talk/Basic acquisition card or no
direct connection via the UPS BUS port),

Talk/Basic acquisition cards,
◗ installation in duo mode (two modules)
