244 Operating Instructions, 07/2019, A5E33329501-AC
Run Time Relay 3 (3.2.7.2.)
Read or set the total running time of Relay 3 in hours.
Relay Pump 1 (3.2.7.3.)
Read only. Relay assigned to Pump 1.
To change the relay assignment, see Relay Pump 1 (2.7.1.2) (Page 185).
Relay Pump 2 (3.2.7.4.)
Read only. Relay assigned to Pump 2.
To change the relay assignment, see Relay Pump 2 (2.7.1.3) (Page 185).
9.3.2.8 Temperature Peak Values (3.2.8.)
This feature displays the high and low process temperatures in °C.
If the device is powered up without a temperature sensor connected, the default fixed
temperature value 20 °C is displayed [see Fixed Temperature (2.12.1.4.) (Page 219)]. This
information can help trace problems with both built in and external temperature sensors.
Highest Value (3.2.8.1.)
View the highest process temperature encountered, as measured by the transducer in ° C.
Lowest Value (3.2.8.2.)
View the lowest process temperature encountered, as measured by the transducer in ° C.
9.3.2.9 Echo Quality (3.2.9.)
Figure of Merit (3.2.9.1.)
This value measures the quality of the reported echo value: higher values represent better
quality. This measure combines the noise level, quality of tracking, and signal strength. (For
more details see Echo Processing (Page 291))
