15. MGB system diagnostic messages
All diagnostic messages are listed below. The scope of the possible messages can differ depending on MGB system version.
Device-specific diagnostic information
Display via MOD LED (see Fig. 16 )
Discrepancy error (two-channel monitoring detected
an error)
Notice:
Ì The discrepancy time is the maximum time during which
channel 1 and channel 2 may have different signal states.
Ì If acknowledgment was unsuccessful, send the device to
the manufacturer.
No. Description Measures/rectifying errors
2721 Emergency stop discrepancy
time exceeded
1. Press emergency stop
2. Acknowledge error (via output
bit Q.G )
2722 Enabling switch detection dis-
crepancy time exceeded
1. Remove enabling switch
2. Acknowledge error (via output
bit Q.G )
2723 Door position discrepancy time
exceeded
1. Open the door
2. Acknowledge error (via output
bit Q.G )
2724 Bolt position discrepancy time
exceeded
1. Open the door
2. Acknowledge error (via output
bit Q.G )
2725 Guard locking discrepancy time
exceeded
1. Open the door
2. Acknowledge error (via output
bit Q.G )
Severe system errors
Ì System errors without error number
Severe system errors are indicated by the rapidly flashing
red LEDs in the bus module. The system must be restarted
for resetting.
Ì System errors with error number
Indication via MOD LED: flashes red
No. Description Measures/rectifying errors
2750 Severe system error The error indicates an overload
problem on the safe output of the
guard locking solenoid.
Test-pulse error (short-circuit monitoring detected an
error)
Notice:
Ì Emergency stop must
not
be pressed during acknowledg-
ment.
Ì If acknowledgment was unsuccessful, send the device to
the manufacturer.
No. Description Measures/rectifying errors
2731 Emergency stop test pulses
erroneous
Safety function is switched off while
no test pulses are being detected.
1. Check system
2. Acknowledgment via output bit
Q.G required.
2732 Enabling switch detection test
pulses erroneous
Safety function is switched off while
no test pulses are being detected.
1. Check system
2. Acknowledgment via output bit
Q.G required.
2733 Door position test pulses erro-
neous
Safety function is switched off while
no test pulses are being detected.
1. Close door
2. Acknowledgment via output bit
Q.G required.
2734 Bolt position test pulses erro-
neous
Safety function is switched off while
no test pulses are being detected.
1. Close door
2. Acknowledgment via output bit
Q.G required.
2735 Guard locking test pulses erro-
neous
Safety function is switched off while
no test pulses are being detected.
1. Close and lock door
2. Acknowledgment via output bit
Q.G required.
2736 Operating mode selector test
pulses erroneous
Safety function is switched off while
no test pulses are being detected.
1. Check system
2. Acknowledgment via output bit
Q.G required.
General messages of the overall system
No. Description Measures/rectifying errors
2741 Information: 1 million operating
cycles exceeded
–
2742 Internal device error Restart the system. If the fault
persists, please contact our support
team.
2743 Signal sequence erroneous (e.g.
broken bolt tongue detected)
1. Check mechanical functions
2. Error must be acknowledged
twice (via output bit Q.PF ). The
safety door must be open.
2744 Plausibility check detected
an error (e.g. escape release
actuated)
Important: The resetting procedure
is contained in the section “Latching
fault when actuating the escape
release”
Ì
Acknowledge error (via output bit
Q.PF )
2745 Locking module in error Restart the system. If the fault
persists, please contact our support
team.
