Diagnostics
10.1 In the event of faults or errors
Cease operation if the cause of the malfunction has not been clearly identified!
Stop the machine if you cannot clearly identify or allocate the error and if you cannot safely
rectify the malfunction.
Complete function test after rectification of fault!
Carry out a full functional test after a malfunction has been remedied.
The ERROR operational status
With certain malfunctions or a faulty configuration, the Flexi Classic enters the safe status.
The ERR LEDs of the safety controller modules show the corresponding errors. To place
the device back in operation:
=
Rectify the cause of the malfunction in accordance with the indication of the ERR LED.
=
Switch the voltage supply of the Flexi Classic off and back on again.
10.2 Replacement of a module
If in an existing Flexi Classic system a module is replaced, the following has to be
observed:
UE410-MU and UE410-GU
Each time a device is replaced, it is necessary to accept the system configuration again
(see section 9.1 “Accepting the system configuration” on page 92).
UE410-XU
If in an existing Flexi Classic system a device is replaced by another device with a differing
revision code (e.g. C-XX to E-XX), then it is necessary to accept the system configuration
again (see section 9.1 “Accepting the system configuration” on page 92). This is not
necessary if the revision code remains the same.
UE410-8DI
If in an existing Flexi Classic system a device is replaced by another device with a differing
revision code (e.g. C-XX to E-XX), then the system configuration must be accepted again
(see section 9.1 “Accepting the system configuration” on page 92). This is not necessary if
the revision code remains the same.
Additionally from revision code D-XX or higher you must pay attention to the wiring: If the
devices were wired as described in these operating instructions (see section 3.8.5
“Connection of sensors to the UE410-8DI” on page 54), no change is necessary. If the
devices were wired e.g. via external distributor modules (X1 and X2 led back to I1 to I8),
then a module exchange from revision code
≤
C-XX to ≥ D-XX requires that connection I5 is
exchanged with I6 and I7 is exchanged with I8.
