Bit assignment of alarm numbers
Determining the alarm type
from the alarm number total
The alarm numbers are
determined in order
from
the largest value.
Here we will
consider the case when the total value of alarm numbers is
10.
T From the six alarm
numbers (Table
4-1),
determine the largest
alarm
number that does not
exceed the total value of alarm numbers.
[a]
Total value
of
alarm numbers: 10
[b] The
largest alarm number that does not exceed the total value
of
alarm numbers: 8
[c]
Alarm number
determined
from
[a] and [bj:
8
Z Subtract the
alarm number determined in step 1 from the
total value of
alarm
numbers.
[af[c]:
IO-S-^2
Z Like step
1
.
determine the largest alarm
number that does not exceed
the
difference value of step 2.
[d]
Difference
value
of
step 2: 2
[e] The
largest alarm number that does not exceed the
difference
value
of
step
2:
2
[f]
Alarm number determined
from
[d]
and [ej: 2
4^
Subtract the
alarm number determined in step 3 from
the difference
value
of
step
2.
[d]-[f]:
2-2^0
5. Repeat the
procedure until the difference value is 0.
From [c]
and
[f],
we conclude
that alarm number
8
(OHP) and alarm
number
2
{ OCP)
have occurred.
Clearing alarms
After
correcting the cause of the alarm,
press the CLEAR
key of the frame. The
alarm
will be cleared.
iN^
•
The alarm
number
will
be displayed until
the alarm is cleared using the
CLEAR
key.
However, if current limit or power limit is
selected for the action to be taken
when the OCP
or the OPP trips, respectively, the alarm
number clears when the
cause of the alarm
is corrected.
