xx = 00-29.
The auto-resettable fuses PTC9 and PTC10 (total max 1A) has been
activated. Check for overload or damage on the MMI board. To reset the
PTC, disconnect the MMI board and wait 5 min to let the PTC cool down
before re-connecting the MMI board
FAULT: 24V for routing equipment (F8), CU xx
xx = 00-29.
Check fuse F8 on the main board in control unit no. xx.
Fuse: T500mAH 250V.
Note: This 24V output, together with the 24V outputs for display units, is
also protected by an auto-resettable fuse PTC2 (max 3.15A). If this fault
message occurs and the fuse is not blown, check all the 24V outputs for
combined overload.
FAULT: 24V for routing equipment, control unit xx
Power supply output 0 (J3:3-4). xx = 00-29.
Check fuse F8 on the main board in control unit no. xx.
Also indicated by LED Fault / Disablement "Fire brigade tx" blinking.
Fuse: T500mA L 250V (TR5).
FAULT: 24V for web-server (auto-resettable), CU xx
xx = 00-29.
The auto-resettable fuse PTC11 (max 500mA) has been activated.
Check for overload or damage on the web-server.
To reset the PTC, disconnect the web-server and wait 5 min to let the
PTC cool down before re-connecting the web-server.
FAULT: 24V out, Technical number xxxxxx
