al–1
,
al–2
When
al–1
or
al–2
(or
al
) is displayed on the PV display, the alarm
value for alarm output can be set on the SV display. When the value
exceeds or falls below the set alarm value, the corresponding alarm
output is produced and the ALM indicator on the front panel lights.
Usually, the alarm value is set as a deviation from the set value, but it
can also be set as an absolute value when the event alarm mode is
selected. Set the alarm value by using the Up and Down Keys while
al
is displayed. The message is not displayed if the alarm mode se-
lector is set to position 0. Factory-set to upper-limit, alarm value 0.0.

If the input range is changed so that the main setting no longer lies
within it, the set point will automatically be changed to
inl
. If main set-
ting stays within the range, the set point will remain as it is.
If
inl
is set to a value greater than or equal to
inh
,
inl
will automatically
be set to
inh
+ 1.
If
dp
is set to 3, the leading zero will not be displayed for negative
values, e.g., –0.023 will be displayed as –.023.
Set
inl
and
inh
so that the difference between them (i.e., the resolu-
tion) is 5,000 or less. Otherwise, the display may not function prop-
erly.
