CU 362 (system), manually by switch (Auto/On/
Off) or via SCADA.
Operation
Shows how the system is being
controlled: automatically or manually.
Operating
hours
Number of hours the pump has been in operation
(can be changed if another pump is installed).
Latest runtime The latest operating period of the pump.
Time since
service
The time elapsed since the pump was last
serviced (can be reset by Grundfos Service).
Time for
service
Time until the next service is due.
Number of
starts
Number of pump starts since the pump was
installed/connected (can be changed if another
pump is installed).
Number of
starts/hour
Number of pump starts in the last hour.
Average flow
Requires an analog level sensor or flow sensor.
See section about pit configuration and flow
calculation.
Latest flow
The calculated/measured flow of the last pump
that was running.
Number of flow
measurements
Requires an analog level sensor.
See section about pit configuration and flow
calculation.
Motor current
The actual average current consumption. 0 A
when the pump stops.
Latest current
The current value when the pump stopped. The
value updates when the pump is running.
Requires a current sensor/ammeter, an MP 204
or a CUE.
Start level
Requires an analog level sensor (not shown with
alternating operation).
Operating
parameter
Description
Stop level Requires an analog level sensor.
