Revision 8.6
SECTION 6 : OPERATION OF CONTROL PANEL
85
RFB & CURRT LOSS S
Yes
Simultaneous loss of rotor feedback and
current feedback the letter S indicates that
the fault occurred at start before the brakes
were released.
6.8.14 (a)
RFB & CURRT LOSS R
Yes
Simultaneous loss of rotor feedback and
current feedback, during operations (after
the brakes were released. The letter R
indicates that during the fault detection
period the rotor feedback was the first fault
to be detected but was followed by a current
loss.
6.8.14 (b)
RFB & CURRT LOSS I
Yes
Simultaneous loss of rotor feedback and
current feedback the letter I indicates that
during fault detection period the current loss
was the first fault to be detected but was
followed by a rotor feedback fault.
6.8.14 (c)
Not in Neutral
Yes
Master controller not in neutral during power
up.
6.8.15
Drive Level
Yes (1)
Minimum drive level required for the Phase
Shifter is below 3,5 V DC
6.8.16
Power On Test
Yes
Routine CPU Test at power up of the unit,
failed.
6.8.17
Brake Release
Yes
One of several of the conditions required
before the brakes are released has failed.
6.8.18
Error Code 100
Yes
Master controller not in neutral during power
up.
6.8.19
Error Code 101
Yes
Watchdog reset
6.8.20
Error Code 102
Yes
Brown out trip
6.8.21
Error Code 103
Yes
CPU internal loss of messages
6.8.22
Error Code 104
No (1)
CPU failed to read saved parameters from
EEPROM
6.8.23
Error Code 106
Yes
Control card system fault
6.8.24
(1) These faults can not be reset in Neutral if they still remain active.
6.8.
POSSIBLE CAUSES OF FAILURE
The aim of this chapter is to assist the user in getting to the cause of the fault as quick as possible,
although great effort has been put into describing as many causes of faults as possible. It is almost
impossible to cover every single aspect of the whole crane installation without running the risk of
creating a guide, which then looks more like a technical book. The desired speed required repairing or
correcting the fault would then be lost in the extensive reading and searching for the current fault
definition.
