2721 Emergency-stop discrepancy
time error
The time between Estop Channel A and Channel B
changing state exceeded the maximum allowable
time.
Press the emergency stop button. Unlatch the
fault by cycling output GeneralFaultUnlatch.
GeneralFaultUnlatch
2722 Enabling switch discrepancy
time error.
The time between Enabling Switch Channel A and
Channel B changing state exceeded the maximum
allowable time.
Remove the enabling switch. Unlatch the fault by
cycling output GeneralFaultUnlatch.
GeneralFaultUnlatch
2723 Door position discrepancy
time error
Discrepancy between both microprocessor
channels of module
Open the guard door. Unlatch the fault by cycling
output GeneralFaultUnlatch.
GeneralFaultUnlatch
2724 Bolt position discrepancy
time error
Discrepancy between both microprocessor
channels of module
Open the guard door. Unlatch the fault by cycling
output GeneralFaultUnlatch.
GeneralFaultUnlatch
2725 Guard Locking discrepancy
time error
Discrepancy between both microprocessor
channels of module
Open the guard door. Unlatch the fault by cycling
output GeneralFaultUnlatch.

2731 Emergency-stop test pulse
error
No test pulses are being detected by the Estop
monitoring circuit.
This problem can be the result of a short circuit on
one or both of the emergency stop contacts. Press
and release the emergency stop button. Check for
signs of abuse or tampering. Inspect the switch
casing for damage. The lock module cover (with
EStop) may need to be replaced. Unlatch the fault
by cycling output GeneralFaultUnlatch.
GeneralFaultUnlatch
2732 Enabling switch test pulse
error
No test pulses are being detected by the Enabling
Switch monitoring circuit.
Check enabling switch connection for a possible
short circuit on one or both of the enabling switch
contacts. Replace the enabling switch if there are
any signs of abuse or tampering. Unlatch the fault
by cycling output GeneralFaultUnlatch.
GeneralFaultUnlatch
2733 Door position test pulse error No test pulses are being detected by the Guard
Door Position monitoring circuit.
Open and close guard door. Unlatch the fault by
cycling output GeneralFaultUnlatch.
GeneralFaultUnlatch
2734 Bolt position test pulse error No test pulses are being detected by the Bolt
Position monitoring circuit.
Open and close guard door. Unlatch the fault by
cycling output GeneralFaultUnlatch.
GeneralFaultUnlatch
2735 Guard locking test pulse error No test pulses are being detected by the Guard
Lock monitoring circuit.
Close and lock the guard door.Unlatch the fault by
cycling output GeneralFaultUnlatch.

2741 Max. service life of 1,000,000
operations has been reached
The module has reached the Maximum
Mechanical Lifetime of 1,000,000 operations.
No action required. For information only. N/A
2742 Internal module error Indicates an unrecoverable fault. The module may
need to be replaced.
Power cycle the access box. If the error persists,
the bus/lock module may need to be replaced.
None
2743 Signal sequence error The module detected an unacceptable sequence
of events (for example, guard locking is active
while the guard door is in the open position).
Check the mechanical function of the handle
assembly and bolt actuator. Open the guard door.
While the guard door is open, unlatch the fault by
cycling output LockSequenceFaultUnlatch.
LockSequenceFaultUnlatch
2744 Lock module error The module detected activation of the escape
release handle or the manual release.
Open and close the guard door. Unlatch the fault
by cycling output LockSequenceFaultUnlatch.
LockSequenceFaultUnlatch
2745 Transponder read error Indicates an unrecoverable fault. The module may
need to be replaced.
Power cycle the access box. If the error persists,
the bus/lock module may need to be replaced.
None
2750 Power supply or CIP Safety
parameter assignment error
This error indicates a problem with the power
supply or a CIP Safety parameter assignment error.
Disconnect and reconnect the power supply. None
