4.3.3 Turning on/off the RJC Using the Switches on the
Front Panel.
This operation is only for thermocouple input.
Turn the selection switch to “7”. Turn the adjustment switch coun-
terclockwise to turn off the RJC sensor after 1 second. Turn the
adjustment switch clockwise to turn on the RJC sensor after 1
second.
NOTE
●
Be sure to set the selection switch back to the position
“0” after each adjustment. Otherwise it may cause an in-
correct operation or malfunction because the positions
other than “0” are adjustment modes.
●
When the selection switch is set to the positions other
than “0”, the setting tool can not be used for the setting.
●
The RJC is turned on when the power is turned on again
after turned off.
5. SETTING PARAMETERS
Set the parameters using a PC (VJ77 Parameter Setting Tool) or the
Handy Terminal. Refer to “6. List of Parameters” in this manual and the
User’s Manual for VJ77 PC-based Parameters Setting Tool (IM
77J01J77-01E) or the User’s Manual for JHT200 Handy Terminal (IM
JF81-02E). Parameters are indicated inside the [ ].
The initial value of the input range is set up according to the selected
values of the input sensor type, input type and temperature unit.
Set the parameters as follows.
Setting regarding to the input: set sequentially from 1.
(1) Set the input sensor type.
(2) Set the input type.
(3) Set the temperature unit for temperature input.
(4) Set the input range.
5.1
Setting Thermocouple Type
Set the thermocouple type to be connected to the input in [D08: TC
TYPE].

5.3
Setting Temperature Unit
Set the temperature unit of the input range in [D19: UNIT].
5.4
Setting Burnout Action
Set the burnout action in [D43:BURN OUT].
Set "OFF", "UP", or "DOWN."
NOTE
●
Changing the input range and the burnout action
direction resets the input adjusted value and the wiring
resistance corrected value.
●
Execute the wiring resistance correction when the
burnout action direction or input wiring is changed.
5.5
Setting Input Range
Set the input range 0% in [D27:INPUT1L_RNG], and the input range
100% in [D28:INPUT1H_RNG].
5.6
Correcting Wiring Resistance
Correct the wiring resistance in [P01:WIRING R].
Select “EXECUTE” for correction, and “RESET” for resetting the cor-
rected value.
Perform wiring as the figure shown in “4.3.2 Correcting Wiring Resis-
tance Using the Switches on the Front Panel” before correcting the wir-
ing resistance.
