⑩ Undershoot
⑪ Sensor type (resistance sensors Pt100, 3-wire thermocouples type K)
⑫ Basic hysteresis (10%)
⑬ Extended hysteresis (+10%)
Status display on analog devices:
Status Green LED "Ready" Red LED "Theta"
No supply voltage OFF OFF
Supply voltage + no overshoot/undershoot ON OFF
Supply voltage + overshoot/undershoot ON ON
Supply voltage + short-circuit ON ickers
1)
Supply voltage + wire break ON ashes
2)
Selected temperature measuring range is at the limit of two setting ranges ickers
1) 3)
Range overshoot or range undershoot ON Flashes
1) with a frequency of 8.0 Hz.
2) with a frequency of 0.5 Hz.
3) Status display depends on the sensor status
Note
In the event of an error (e.g. wire break or short-circuit in a sensor cable), the device enters sleep
mode (change-over contact 11/14 open, 11/12 closed)
