If PV has exceeded Indication range, Control range, the PV Display indicates [
alternately.
If PV has dropped below Indication range, Control range, the PV Display indicates [
[ ] alternately.
If thermocouple, RTD or DC voltage (0 to 1 V DC) input is burnt out or disconnected, the PV Display
indicates [ ] and [
If DC voltage or current input is disconnected:
For 4 to 20 mA DC, 1 to 5 V DC inputs, the PV Display indicates [
For 0 to 20 mA DC, 0 to 5 V DC and 0 to 10 V DC inputs, the PV Display indicates the value
corresponding with 0 mA DC or 0 V DC input.
OUT1 and OUT2 are turned OFF (OUT1 low limit value for Direct current output type).
For Manual control, the preset MV is output.
If Alarm or Loop break alarm is selected in [Event output EV1/EV2 allocation], Event output will be
turned ON under the alarm active conditions.
In Program control, Burnout is enabled even in standby (program control waiting) mode.
[Output status when input errors occur] can be used only for controllers using Direct current input
and voltage input, and Direct current output.
For manual control, the preset MV is output.
