9.3 Resetting saved alarm messages (RESET button)
If the fault memory is enabled, the alarm state will remain, even after the cause of the fault
has been eliminated, until a "RESET" is carried out.
A RESET is carried out in the following way:
• Press the "RESET" button on the front panel of the EDS44x-L twice (EDS44x-L only)
• Press an external RESET button connected to the EDS44x-x
• Send a RESET command via the BS bus (EDS44x-x)
Saved alarm messages that are no longer pending are deleted, the alarm relay is de-en-
ergised, the alarm LEDs go out and no alarm messages remain on the BS bus.
9.4 Deactivating the buzzer and resetting the fault message
• Press the RESET button on the EDS44x-L to mute the buzzer for the present alarm
message.
• To reset a fault message, press the RESET button again.
The buzzer functions can be assigned in the device menu of the ISOMETER®. For further
information, refer to "Digital outputs of the EDS44x-L" on page 38 or to the manual of the
ISOMETER®.

front panel of the EDS44x-L.
• Press an external TEST button connected to the digital input

After finishing the test, all LEDs must go out again, except the "ON" LED.
