Basically, the temperature range that can be measured is deter-
mined by the temperature sensor to be used. For example, when a
K-type (chromel-alumel thermocouple) temperature sensor is se-
lected, the measurable range is from –200
%
C to 1,300
%
C. Howev-
er, this temperature range can be narrowed, for example, to 0
%
C to
400
%
C. To do this, set the lower-limit value of the temperature set-
ting range, in this case to 0
%
C, on the SV display by using the Up
and Down Keys while
5l–l
is displayed on the PV display. Similarly,
set the upper-limit value, 400
%
C, while
5l–h
is displayed. If the pro-
cess temperature falls below the set lower-limit value or exceeds
the set upper-limit value, it is displayed on the PV display within the
temperature range of the temperature sensor.
Hysteresis Alarm:
hysa
The hysteresis alarm value for the alarm can be set in a range from
0.0
%
to 999.9
%
C while
hysa
is displayed on the PV display using the
Up and Down Keys. The factory setting is 0.2

Disable band:
db
The disable band can be set in a range from 0.1% to 10.0% while
db
is displayed on the PV display using Up and Down Keys. The factory
setting is 2.0%.
Motor Calibration:
calb
Designate whether or not to perform motor calibration. To enter the
mode, simultaneously press the Up and Down Keys for at least one
second. Press the Display Key to return to
sl–l
.
WARNING
Never calibrate the motor during control operation. Make sure
that control operations have been stopped before calibrating.

Level 2
In level 2, selected input sensor, and modes for alarm output can be
monitored. Note that level 2 is a monitoring level only and thus no
parameters can be changed. When the Level Key is pressed for 2
seconds minimum after power application,
5l–l
is displayed on the
PV display. Hold down the Level Key again for 2 seconds minimum
to display
o
on the PV display. Then, selected input sensor, and
alarm modes can be monitored each time the Display Key is
pressed.
