Selection of Bank Number
1. To select the bank number with key input, set pin 7 of the
function selector to the OFF position first. Select display level
1 with the Level Key and press the Display Key. Then select
the bank number with the Up and Down Keys. The selected
bank number will appear on the SV Display.
2. To select the bank number with the bank selection terminal
input, set pin 7 of the function selector to the ON position first.
Then connect (short-circuit) or disconnect (open) the
following bank terminals to the SG terminal (terminal 1):

Disconnect all terminals.
1
Connect only Bank terminal 0 to SG.
2
Connect only Bank terminal 1 to SG.
3
Connect Bank terminals 0 and 1 to SG.
4
Connect Bank terminal 2 to SG.
5
Connect Bank terminals 0 and 2 to SG.
6
Connect Bank terminals 1 and 2 to SG.
7
Connect Bank terminals 0, 1, and 2 to SG.
Level 1
In this level, parameters such as upper- and lower-limit values of the
setting limit, control period, hysteresis, heater current, and heater
burnout alarm are set.

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
°
to 1,300
°
C. However,
this temperature range can be narrowed, for example, to 0
°
to
400
°
C. To do this, set the lower-limit value of the temperature setting
range, in this case to 0
°
C, on the SV display by using the Up and
Down Keys while “
sl-l
” is displayed on the PV display. Similarly,
set the upper-limit value, 400
°
C, while “
sl-h
” is displayed. If the
process 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.
Control Period:
cp
When “
cp
” is displayed on the PV display, the control period can be
set or changed in a range from 1 to 99 seconds in units of 1 second.
The factory setting is 20 seconds. When a Voltage Output Unit is
used, it is recommended that the control period be set to 20 seconds
or less (ideally, about 2 seconds), so that the control operation can
be performed more accurately.

Hysteresis:

The hysteresis value for the ON/OFF control can be set in a range
from 0.0

C/

F while “
hys
” is displayed on the PV display
using the Up and Down Keys. The value is factory-set to 0.8

Heater Burnout Alarm:
hb
A burnout current value can be set to detect heater failure. First, the
current measured in the heater current value mode will be displayed
in amperes. The normal current value is the current value with the
control output ON. Disconnect the heater and read the current value
and obtain the set value from the following:
Normal current value + Current value with disconnected heater
2
Use the Display Key and set the PV display to
hb
. The difference be-
tween the normal current and the one with a disconnected heater
should be 2.5 A minimum. If it is less than 2.5 A, the operation to de-
tect heater disconnection will not be stable. The value can be set in a
range of 0.1 to 49.9 A in units of 0.1 A.
Note:
1. Do not allow a current exceeding 50 A to flow in the Con-
troller; the maximum continuous heater current is 50 A.
2. Set the value to 0.0 A if the heater burnout alarm is not
used, in which case the alarm will not function at all.
