Reference ED900 double door installation manual.
1. Check communication cable connection at the two operators.
• Cable connects to the horizontal RJ 45 connector next to the user
interface. Check communication cable.
1. The initial current measuring test my not always be successfully
completed due to system tolerances and environmental conditions.
2. The test may also fail, as an example, if someone uses the door while the
test is in progress.
1. The initial braking circuit test my not always be successfully completed
due to system tolerances and environmental conditions.
2. The test also may fail, as an example, if someone uses the door manually
while the test is in progress.
3. If the cyclical test fails ten times in a row, error message ln 73 will be
displayed.
1. Reconnect the corresponding DCW® device.
2. If this is not possible, reactivate the drive. Reactivation can be done by:
• Switching program switch to Close (off).
• Pressing both 4 button keypad left
than 3s.

Troubleshooting error codes
1. Probable causes are a defective locking device or wiring defect.
• Check the locking device and feedback system.
1. Check the DCW® program switch and its connections.
1. Factory setting level of "safety sensor test" parameter ST is 0,
test off (Appendix A, Parameter detail).
2. When ST is configured to installed safety sensors, a test signal is
sent to the sensors before each door opening or closing cycle.
Operator waits for a response within a certain time window.
3. Check whether parameter ST has been configured to the
installed safety sensors and their active-high or active-low signal
level.
4. Check for activation of the test at the safety sensors.
1. Using dormakaba handheld, reload current firmware to
reinitialize system.
2. If the error is still present, the control unit must be replaced.
