Reset Terminal (Reset Latching Alarms)
Latching alarms can be released via terminals 7 and 8 by closing a contact (key, etc.) (same func-
tion as the RESET key on the front panel).
Acknowledge Terminal (Reset Horn Relay)
The horn relay can be reset via terminals 5 and 6 by closing a contact (key, etc.) (same function
as the ACKNL key on the front panel).
LOCR Terminal
The relay inhibit for the MRO 8 module (common alarms) on the rear of the rack can be activated
via terminals 3 and 4 by closing a contact (key, etc.). All 8 modules are inhibited as a block. This
terminal has no effect on the MRO 8 TS modules. These modules are inhibited via the LOCK ter-
minal on the MRC TS module (Chapter 10.7).
NOTE: If the voltage supply for the MIB module is interrupted, the inhibiting function of the MRO
8 modules is no longer active.
Password Terminal
The input of the configuration password can be replaced via terminals 1 and 2 by closing a contact
(key switch). If the current password has been forgotten, this terminal can be used to enter a new
password (Chapter 10.5).
