Note: Unless otherwise specified, the measuring ranges are K thermocouple
0.0-800.0˚C for multi input and 0-10VDC: 0.0 - 100.0 for voltage (V)
input at the time of shipment from the factory.
Note: Do not use the above sensors (current/voltage, thermocouple, R.T.D.)
for the measurement of power supply line.
10. Maintenance and Troubleshooting
10-1. Procedure of Maintenance Replacement and Matters
Be attended to (Steps for replacing defective items)
Confirmation of Model Code:
Check the model code of the component part in trouble.
(Open the control box, and you can find an appropriate code in the
model label affixed to the instrument case.)
Inquiry on Input Data:
Ask the manufacturer if input data (control date of external
operation, event output, set value of position, etc. at the time when
an error occurs) is necessary or not.
Confirmation of Present Wiring Condition:
Check and record the present wiring condition. Please note that in
case input data is necessary for control, the same control operation
as before is not possible with a replaced product unless such data
is input.
Confirmation of Present Input Data:
When data is not known, call the input date for the product, check
and record it. In case input data is required, the same control
operation as before is not with a replaced product unless such data
is input.
Repair of Present Product or Procurement of New Product:
In case the product in trouble is removable from the site of
installation, remove and have it repaired. If it is not possible,
arrange to acquire a new product for replacement.
Setting before Starting Operation:
When replaced by a new product, check the wiring, apply power
and set items as described in 8. Before Starting Up.

Problem with power supply
and wiring
Deterioration of the
connection product.
Inspect portions related
to power source and
wire connection.
Check wiring.
Examine the product
and repair or replace.
Key unable to
be operated.
Keylock is in effect.
Deterioration of the product.
Release keylock.
Examine and repair or
replace the product.
ON-OFF action
of control
output is too
fast.
ON-OFF is set for P of PID.
Too small a value set for
hysteresis of ON-OFF action.
Change the OFF set for
P to two-position type
ON-OFF action.
Increase the hysteresis
value of ON-OFF
action.

Check R.T.D. input A wiring
for a possible break. If

replace R.T.D.
For voltage or current input,
check the transmitting unit
of measured values.
Check if set code of
