Remote-fault-reset happens within a too short distance
EN 14459 permits a remote unlocking only 4 x within 15 minutes.
The fault release is monitored by the remote control software, LAMTEC system
bus, and field bus (parameter 19). When exceeded, fault deactivation H889 is gen-
erated and additional remote fault releases are ignored.
After a waiting period, another remote fault release can be performed.
Fault deactivation H889 also takes place if the fault release was sent even though
none is present!
The release is monitored by terminal, while the programming unit and customer
interface are switched of by the standard setting of parameter 19. A release through
the front panel is always possible.

Fault during an internal self-test.
Reset the fault; switch the mains voltage off and on again if necessary.
If fault messages are constantly appearing one after the other
exchange the
device or respective card.
If the fault appears after a sotware update, the version of the monitoring processor
may be incompatible with the version of the main processor.

For ETAMATIC:
Are another 24V than those of terminal 24 being used?
Check the voltage level.
Short circuit on the 24V
Disconnect 24: no arrow must be pointing at digital inputs.
Connect terminal 24 to only one input
Voltage on
If the fault still occurs: Deactivation in ETAMATIC defective.
