FAULT: 24V for external equipment output 1 (F9), CU xx
xx = 00-29.
Check fuse F9 on the main board in control unit no. xx.
Fuse: T1.6AH 250V.
This 24V output, together with the other 24V outputs for external equipment (2-4), are also protected by an
auto-resettable fuse PTC1 (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 external equipment output 2,3,4 (F10), CU xx
xx = 00-29.
Check fuse F10 on the main board in control unit no. xx.
Fuse: F3.15AH 250V.
These 24V outputs, together with the other 24V output for external equipment (1), are also protected by an
auto-resettable fuse PTC1 (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 MMI (auto-resettable), CU xx
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.
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 com
-
bined overload.
FAULT: 24V for Gateway (auto-resettable), CU xx
xx = 00-29.
The auto-resettable fuse PTC11 (max 500mA) has been activated. Check for overload or damage on the Gateway.
To reset the PTC, disconnect the Gateway and wait 5 min to let the PTC cool down before re-connecting the Gateway.
FAULT: 24V out, output unit xxxxxx
This is valid for the external power supply 3366 or 4466 on the COM loop.
The output might be turned off or the current output limit is exceeded.
