13 OPERATION AND MAINTENANCE
13.1 PROPER OPERATION RULES
The control panel unfailing operation depends on maintaining appropriate operating conditions,
power supply voltage, batteries condition and periodical inspections performance.
The periodical inspections should be carried out by an Authorised Service Station that was appointed
by the user to perform maintenance works. Any damage should be immediately reported to the
service station. In the case of fuse replacement, attention should be paid to their nominal values. It is
not allowed to replace a burnt fuse with a spare fuse with a greater nominal value, since it can result
in the unit damage.
The following fuses are used in the POLON 4900 control panels:
a) in the power supply segment:
B1/6.3 A F6,3L250 V type – protection of the battery cluster circuit;
B2/1 A F1L250 V type – protection of the + 24 V additional external devices power supply;
b) in the MSL-48M modules:
B1/500 mA F500L250 V type – protection of MSL-1M, MSL-2M modules;
c) in the MIK-48 module:
B1/500 mA F500L250 V type – protection of MIK-48 interface module;
d) in the PPW-49 module:
B1/630 mA F630L250 V type – protection of LS1 signalling line;
B2/630 mA F630L250 V type – protection of LS2 signalling line.
13.2 PERIODIC INSPECTIONS AND MAINTENANCE RULES
The POLON 4900 control panel periodical inspections, according to the point 11.2 of the PKN-CEN/TS
54-14:2006 standard, should be carried out at least once per year.
