7 MAINTENANCE
7.1 Maintenance Inspection
To use the S10mini or S10V in an optimum condition, check the items listed below. Make this
check at routine inspection or periodic inspection (twice or more per year).
(1) Module appearance
Check that no fissure or crack exists in the module case. If the case has such a damage,
there is a possibility that the internal circuit may also be damaged, resulting in a system
malfunction.
(2) Indicator's ON status and indication
From the indicator status, check that no special fault exists.
(3) Looseness of mounting screws and terminal base screws
Check that the mounting screws and terminal base screws of the module are not loose. If
any of these screws is found to be loose, tighten it. Such a loose screw may result in a
system malfunction or a burn-out due to overheating.
(4) Module replacement
Hot swapping of modules will lead to hardware or software damage. Be sure to replace a
module in a power OFF state.
(5) Cable sheath condition
Check that the cable sheath is not abnormal. A peeled sheath may cause a system
malfunction or electric shock, or may result in a burn-out due to short circuit.
(6) Dust sticking condition
Check if dust and dirt collects on the module. If dust collects on the module, remove it with
a vacuum cleaner. Dust on the module may short the internal circuit, resulting in a burn-
out.
(7) Power supply voltage
Check that neither the internal power supply of the module nor the external power supply to
it is out of the specified range. If the power supply voltage deviates from the rating, a
system malfunction may result.
Static electricity may damage the module. Before starting the work, discharge
all electrostatic charge from your body.
