Input error
Overscale
PV has exceeded Input range high limit value (DC voltage, current inputs:
Scaling high limit value).
PV and [ ] are alternately indicated in the PV Display.
For Manual control, the preset MV is outputted.
Underscale
PV has dropped below Input range low limit value (DC voltage, current
inputs: Scaling low limit value).
PV and [ ] are alternately indicated in the PV Display.
For Manual control, the preset MV is outputted.
Burnout
If PV has exceeded Indication range, Control range, the PV Display
indicates [ ] and [ ] alternately.
If PV has dropped below Indication range, Control range, the PV Display
indicates [ ] and [ ] alternately.
OUT1 and OUT2 are turned OFF (for Direct current output type,
OUT1/OUT2 low limit value).
For Manual control, the preset MV is outputted.
If thermocouple, RTD or DC voltage (0 to 1 V DC) input is burnt out or
disconnected, the PV Display indicates [ ] and [ ] alternately.
If DC voltage (1 to 5 V DC) or current (4 to 20 mA DC) input is
disconnected, the PV Display indicates [ ] and [ ] alternately.
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.
[Output status when input errors occur] can be used only for controllers using Direct current and
voltage inputs, and Direct current output.
For manual control, the preset MV is outputted.

Warm-up indication
After the power supply to the instrument is turned on, the PV Display
indicates the input type, and SV Display indicates input range high limit
value (for thermocouple, RTD inputs) or scaling high limit value (for Direct
current and voltage inputs) for approximately 3 seconds.
Console
communication
By connecting to the tool cable (CMD-001, sold separately) to the
console connector, the following operations can be conducted from an
external computer, using the Console software SWC-BCx01M.
Console communication and Serial communication (C5W option) cannot
be used together.
• Reading and setting of SV, PID and various set values
• Reading of PV and action status
• Function change
Communication interface: C-MOS level
