During Operation
Once LIMAX33 CP-00 was commissioned correctly, it is only in the following cases that any necessary opera-
tions are required on LIMAX33 CP-00:
Emergency evacuation and troubleshooting if a safety function has been triggered or in case of defects
of the system itself (only if necessary)
Setting the parameters (only if necessary)
Examination of the elevator by the notified body (after commissioning and then annually)
12.1
Triggering the Safety Functions
When an elevator fault, which is covered by the safety functions described in chapter 8, occurs, the actuator-
contact specified for the respective safety function is opened
12.2
The Error Level and Error Codes
LIMAX33 CP-00 has a variety of self-diagnostic functions to ensure functional safety. When the self-diagnostic
function detects a defect, a unique error code identifying the specific error is set in addition the error level de-
fined for this specific error. The error-level determines the reaction of the LIMAX33 CP-00:
Table 9: Error -level
0
No reaction, No error or error with level 0 (for information) is set.
1
If the cabin moves there is no reaction for the time being. As soon as standstill is reached,
the error level is increased to level 2, and the LIMAX33 CP-00 reacts corresponding to level 2
2
OC opens
3
Reserve (may be for later use)
4
eSGC, OC and SR1/(SR2) open
An error level can only be increased. That means that the corresponding actuators will be kept open even if the
cause for the error disappeared – with exception of the undervoltage errors, they will disappear as soon as the
undervoltage disappears.
But at power cycle or CO-reset the error level will get lost. Therefore, the corresponding actuators may close
again if the cause for the error disappeared.
The error codes are also stored in the defect logs (A & B).
It’s the task of the lift control to read all error codes from defect registers
A and B which appear and to display them together with date and time.
If an error occurs, the technician reads all error codes which appeared since last lift operation without error.
The table below gives hints for troubleshooting. If the error affects the lift or the external wiring, LIMAX33 CP-00
is not defective and need not be replaced.
If the error affects LIMAX33 CP-00, the concerned component must be replaced. An error reset without replac-
ing the component is then not allowed.
In case of an error-level >0 is set, LIMAX33 CP-00 does not accept teaching of floors or of reference positions.
