Troubleshooting
40 Minimum angle not achieved on reference run:
during a reference run (homing), the glass wing mechanism
must move through a minimum angle, otherwise the refer-
ence run cannot be completed.
→ Check whether the glass wings have been blocked by an
obstacle.
41 Invalid program mode set:
DIP switches S2.1 and S2.2 are set to an invalid program
mode.
42 MMC-120 cannot be activated when starting:
at least one MMC-120 cannot be activated by the CAN bus
during a program start.
→ CAN communication between MBC-110 and MMC-120 is
malfunctioning, error at MMC-120
43 Error in MMC-120 detected during operation:
at least one MMC-120 has detected an internal error.
→ Read error code on MMC-120 LEDs and look for cause.
60
Error when initialising CAN protocol stack:
internal software error in MBC-110
61 Error when initialising CAN bus:
CAN bus is blocked, e.g. by a short circuit in the CAN cable.
62 No communication with MMC-120 in operation:
possible causes: CAN cable broken or plug not correctly in-
serted, wrong CAN address set, termination resistors not
correctly set, old firmware on MMC-120 (-> download MBC-
110 to MMC-120 required)
64 MMC-120 does not answer during operation:
see Error 62 for possible causes
65 EEPROM error in MBC-110:
the EEPROM memory in MBC-110 could not be read or writ-
ten in.
→ Possibly hardware error in MBC-110
66 Checksum error in parameter memory:
it has been found that the program in the parameter memory
no longer agrees with the checksum.
→ Hardware defect, send the unit to MAGNETIC for repair.
70 Error in photocell LS 1:
photocell covered for longer than 30 seconds.
→ Dirty or defective?
71 Error in photocell LS 2
72 Error in photocell LS 3A/B
73 Error in photocell LS 4A/B
74 Error in photocell LS 5
75 Error in photocell LS 6

Self-resetting errors are shown for not more than 10 seconds after
elimination of the error. However as long as the error persists, the
error code will be displayed.
When there is an non-self-resetting error, the pedestrian barrier will
go out of service. The error code will be displayed permanently until
it is eliminated.
