3.2 Description
c
Monitor LED
MAX: Maximum PV value display monitor LED (green)
Lights when maximum PV value is displayed.
MIN: Minimum PV value display monitor LED (green)
Lights when minimum PV value is displayed.
HOLD: Hold PV value display monitor LED (green)
Lights when hold PV value is displayed.
COM/SET: Communication / parameter setting monitor LED (green)
Lights when in the communication mode.
Flickers on/off for mode 1 and mode 2 screen groups.
AL1: Alarm 1 output monitor LED (red)
Lights when alarm 1 is output.
AL2: Alarm 2 output monitor LED (red)
Lights when alarm 2 is output.
AL3: Alarm 3 output monitor LED (red)
Lights when alarm 3 is output.
AL4: Alarm 4 output monitor LED (red)
Lights when alarm 4 is output.
d
Measured value display LED (red)
Displays current parameter PV value on basic screen (screen 0-0).
Displays and sets parameters for each mode screen group.
e
Key switch operation section
Display key
Switches PV display from current value
→
maximum value
→
minimum value
→
current value.
Parameter key
Pressing this key displays the next display screen.
Toggles between mode 0 screen group and mode 1 screen group.
Press and hold for approximately 2 seconds to switch from 0-0 to 1-0 screen group and vice versa.
Down key
Decrements parameter values on the setting screens.
The decimal point of the lowest digit flickers on/off until the value is entered by the ENT key.
Up key
Increments parameter values on the setting screens.
The decimal point of the lowest digit flickers on/off until the value is entered by the ENT key.
ENT (enter) key
Enters parameters modified by the up and down keys on the setting screens.
Toggles between display and setting screens. When doing so, the decimal point of the lowest digit stops
flickering on/off.
4. Error messages
The following error messages are displayed on the basic screen (0-0):
When any of the following occurs
c
Break in thermocouple input wiring
d
Break in R.T.D. input A wiring
e
If PV value exceeds higher limit of measurement range by approximately 10%
f
If scaling value exceeds 32,000 for voltage or current input
If PV value falls below lower limit of measurement range by approximately 10%
If cold junction (CJ) is abnormal on higher limit side during thermocouple input
If cold junction (CJ) is abnormal on lower limit side during thermocouple input
If B of R.T.D. (terminal No.
k
or
l
) is broken or if A, B or more than one B is broken
