the type of thermocouple selected. The external resistance
should be100 or less.
(4 In case of R.T.D. input, the resistance value per lead wire
should be 5 or less and all the 3 wires should have the same
resistance value.
(5 Avoid arranging the input signal line to pass through in the
same conduit or duct with high-tension circuit.
(6 Shield wire (one-point grounding is effective to eliminate
the electrostatic induction noises.
(7 An effective way of eliminating the magnetic induction
noises is to twist the input wire in short and equal intervals.
(8 For source power connection, use wire or cable having a
cross section of 1mm2 or larger and performance capacity
equivalent to 600V vinyl insulation wire.

(1) Method of shifting between Mode 0 screen group and Mode 1 screen
group
By pressing the key on the basic screen for 3 seconds or longer,
the display changes to the parameter heading screen of Mode 1
screen group. To return to the basic screen, keep pressing the
key again for 3 seconds or longer.
(2) Method of shifting screen within Mode 0 screen group
By each pressing of the key, screen shift takes place.
When the light of decimal point of the lowest digit place is OFF, by each
pressing of
ENT
key, the screen shifts alternately between the parameter
character indicating screen and the parameter setting screen.
(3) Method of shifting screen within Mode 1 screen group
By each pressing of the key, screen shift takes place.
When the light of decimal point of the lowest digit place is OFF, by each
pressing of
ENT
key, the screen shifts alternately between the parameter
character indicating screen and the parameter setting screen.
(4) Method of setting input scaling screen in Mode 1 screen group
On condition that "Lower limit value < Higher limit value", when the lower
limit value is set with a difference less than 10 counts from that of the higher
limit value, the higher limit value is forcibly changed to a new value at lower
limit value plus 10 counts.
As a result, when the higher limit exceeds 9999 counts, it is changed to the
value of the lower limit value minus 10 counts. Also, when a lower limit
value is set at a value with a difference exceeding 5000 counts from the higher
limit value, the higher limit value is forcibly changed to a new value at lower
limit value plus 5000 counts (−5000 counts).
On condition that "Lower limit value < Higher limit value", when the higher
limit value is set with a difference less than 10 counts from that of the higher
limit value, the lower limit value is forcibly changed to a new value at higher
limit value minus 10 counts.
As a result, when the lower limit exceeds −1999 counts, it is changed to the
value of the higher limit value plus 10 counts. Also, when a higher limit
value is set at a value with a difference exceeding 5000 counts from the lower
limit value, the lower limit value is forcibly changed to a new value at higher
limit value minus 5000 counts (+5000 counts).
On condition that "Lower limit value > Higher limit value", when the lower
limit value is set with a difference less than 10 counts from that of the higher
limit value, the higher limit value is forcibly changed to a new value at lower
limit value minus 10 counts.
As a result, when the higher limit exceeds −1999 counts, it is changed to the
value of the lower limit value plus 10 counts. Also, when a lower limit value
is set at a value with a difference exceeding 5000 counts from the higher limit
value, the higher limit value is forcibly changed to a new value at lower limit
value minus 5000 counts (+5000 counts).
On condition that "Lower limit value > Higher limit value", when the higher
limit value is set with a difference less than 10 counts from that of the higher
limit value, the lower limit value is forcibly changed to a new value at higher
limit value plus 10 counts.
As a result, when the lower limit exceeds 9999 counts, it is changed to the
value of the higher limit value minus 10 counts. Also, when the higher limit
value is set at a value with a difference exceeding 5000 counts from the lower
limit value, the lower limit value is forcibly changed to a new value at higher
limit value plus 5000 counts (−5000 counts).
(5) Method of setting analog output scaling screen in Mode 1 screen group
On condition that "Lower limit value < Higher limit value", when the lower
limit value is set at the same value of the higher limit, the higher limit value is
automatically changed to the lower limit value +1 count. As a result, when
the higher limit exceeds the higher limit of the measuring range, it is changed
to the value of lower limit −1 count.
On condition that "Lower limit value < Higher limit value", when the higher
limit value is set at the same value of the lower limit, the lower limit value is
automatically changed to the higher limit value −1 count. As a result, when
the lower limit exceeds the lower limit of the measuring range, it is changed to
the value of higher limit +1 count.
On condition that "Lower limit value > Higher limit value", when the lower
limit value is set at the same value of the higher limit, the higher limit value is
automatically changed to the lower limit value −1 count. As a result, when
the higher limit exceeds the lower limit of the measuring range, it is changed
to the value of lower limit +1 count.
On condition that "Lower limit value > Higher limit value", when the higher
limit value is set at the same value of the lower limit, the lower limit value is
automatically changed to the higher limit value +1 count. As a result, when
the lower limit exceeds the higher limit of the measuring range, it is changed
to the value of higher limit −1 count.

(1) Setting of alarm higher limit value
For setting the alarm higher limit value, the alarm hysterisis is set by selecting
the higher limit alarm on the alarm code screen of Mode 1 screen group (when
alarm option is attached).
The higher limit alarm is output when the process value exceeds the alarm
level value. The output goes off when the process value comes down below
the alarm level value minus the alarm hysterisis.
(2) Setting of alarm lower limit value
For setting the alarm lower limit value, the alarm hysterisis is set by selecting
the lower limit alarm on the alarm code screen of Mode 1 screen group.
The lower limit alarm is output when the process value comes down below the
alarm level value. The output goes off when the process value exceeds the
alarm level value plus hysterisis.
5-3. Analog output action (option)
The analog output is a function that outputs the analog voltage or analog
current corresponding to the process value. They are used for input signal
into a recorder and data accumulation equipment.
Within the measuring range specified by the lower and higher limit value of
the analog output scaling, analog output signal to correspond to the process
value is available.

5-4. Auto-return function
On any screen other than 0-0 basic screen, if no key operation is made for 3 minutes
or longer, the screen shifts to the basic screen (auto-return).
6. Error message
Abnormal input of process value (indicated on the basic screen of Mode 0 screen
group)
This message is indicated when the thermocouple or A of R.T.D. is
burnt out, also when V value exceeds the higher limit of the
measuring range by about 10%.
When V value is below the lower limit of the measuring range by
about 10%, by reason such as wrong polarity of input wiring.
When the t B (terminal No.7) wire breaks.
When the cold junction (CJ) is abnormal on the higher side in
thermocouple input.
When the cold junction (CJ) is abnormal on the lower side in
thermocouple input.
When the B wire (terminal No.9) breaks, or when plural number of
wires out of A· B · B break.
Note: When abnormality occurs, please contact our sales agent or to our business
office directly.
