During Operation

12.3
The Fault Register
The fault register contains the information if a safety function (
13) tripped.
A detailed description of the fault register can be found in the CANopen specifications.
12.4
Testing of the OC- Relays
When a relay is opened by LIMAX33 CP-00, it is checked by the feedback contacts whether the relay has really
opened. OC is normally always closed during normal lift operation
OC must be checked at least once per day that the OC-Relays are still able to open. This is done normally ex-
plicitly by a command of lift control, refer to CANopen Specification: If LIMAX33 CP-00 receives this command,
it opens OC for a short period of time (approx. half a second), and then it closes OC again.
If LIMAX33 CP-00 did not open OC for longer than 24h (may be because the CAN-command was not received
for some reason), LIMAX33 CP-00 opens OC at next stand still automatically for a short time (approx. half a
second).
If LIMAX33 CP-00 is also not able to perform this test at next stand still for 12h more for some reason (OC
stayed closed for more than 36h), LIMAX33 CP-00 sets the lift out of service by setting of error-level 4.
This is done regardless of the actual movement state.
Remark: Normally it is always possible to open OC for a short time without disturbing normal lift operation
when the car is in stand still.
12.5
Testing of the eSGC-actuator
The eSGC actuator is tested during operation: the eSGC-(solid state-) switch is opened very briefly and it is
thereby tested whether the voltage at eSGC-OUT has dropped off.
The opening for test purposes is so short (<250 µs) that as a rule no disturbing influences on the normal opera-
tion are to be
expected, provided that certain boundary conditions are respected (refer to chapter 8, topic 23 b).
