Thermocouple, RTD input:
If measured value exceeds Indication range high limit value, the PV Display flashes “ ”.
If measured value drops below Indication range low limit value, the PV Display flashes “ ”.
If measured value goes out of the Control range, OUT1 (Limit control output) is turned OFF.

DC input:
Indication range: [Scaling low limit value–Scaling span x 1%] to [Scaling high limit value +Scaling
span x 10%]
However, “ ” or “ ” flashes when a range of –1999 to 9999 is
exceeded.
Control range: [Scaling low limit value–Scaling span x 1%] to [Scaling high limit value +Scaling
span x 10%]
DC input disconnection:
When DC input is disconnected, the PV Display flashes “ ” for 4 to 20 mA
DC and 1 to 5 V DC inputs, and “ ” for 0 to 1 V DC input. 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 or 0 V input.
[Burnout]
When the thermocouple or RTD input is burnt out, OUT1 (Limit control output) is turned off, the PV
becomes its maximum value and the PV Display flashes “ ”.
[Self-diagnosis]
The CPU is monitored by a watchdog timer, and if an abnormal status is found on the CPU,
the controller is switched to warm-up status.
