3.2.6.1. Alarms
History of alarms. Displays type of alarm, value at which alarm triggered,
state of alarm.
3.2.6.2. OCM
Flow logs. Displays head and flow values.
3.2.6.3. Daily Totals
Daily totals for both totalizers. Displays maximum and minimum values for
flow and temperature, average flow, and daily totalizer (DT) and running
totalizer (RT) values.
3.2.6.4. PV
Primary Variable. Displays PV type (e.g. Level), PV value and temperature.
3.2.7. Pump Records
Relay usage.
3.2.7.1. Run Time Relay 2
Read or set the total running time of Relay 2 in hours.
3.2.7.2. Run Time Relay 3
Read or set the total running time of Relay 3 in hours.
3.2.7.3. Relay Pump 1
Read only. Relay assigned to Pump 1.
To change the relay assignment, see
2.7.1.2. Relay Pump 1
.
3.2.7.4. Relay Pump 2
Read only. Relay assigned to Pump 2.
To change the relay assignment, see
2.7.1.3. Relay Pump 2
.
3.2.8. Temperature Peak Values
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.)]. This information can help trace problems with both built in and
external temperature sensors.
3.2.8.1. Highest
Value
View the highest process temperature encountered, as measured by the
transducer in ° C.
3.2.8.2. Lowest Value
View the lowest process temperature encountered, as measured by the
transducer in ° C.
Note: PV is controlled by the mA function (see
2.5.1. Current Output
Function
). Therefore, the LUI operation can be changed (via
2.1.2. Sensor
Mode
) without affecting the process being controlled.
