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%C/%F.

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.
