5. Observe the following steps:
A minor fuse alarm (MNF) should be issued at
approximately the same time that the yellow LED on the
216A Control Unit is turned on which should correspond
to a two-volt drop in the float voltage.
A major fuse alarm (MJF) should be issued at the same
time as the yellow LED on the 216A Control Unit begins
blinking. The six-volt drop will not be seen because the
batteries will not discharge that quickly.
6. Allow the thermistors to cool, then insert and secure them
into the battery string.
7. Verify there are no alarms present at this time.
