4.4 TEST
- permits performing a FUNCTIONAL TEST of the pumps (both the variable-speed pump and the fixed-speed
pump) during first installation or subsequent inspection
- The test procedure is automatically interrupted if not operations are performed from the keyboard for over
60 seconds; DGBOX automatically returns to OUT OF SERVICE mode.
- To access the TEST mode, place the DGBOX in OUT OF SERVICE mode and then press the TEST key (see fig.
below).
For model MW30 use the UP/DOWN arrows to select the pum to test (pump 1 or pump 2).
Variable-speed pump: when the test is started, the pump is supplied at MINIMUM FREQUENCY, to which its
performance will be consequently reduced.
The only operation which can be carried out is to manually INCREASE and subsequently DECREASE the work
frequency (see fig. below) to gradually and reliably determine maximum pump performance.
The exit from TEST mode stop the pump (STOP) and strike ESC, or strike ESC only; DGBOX will exit from TEST
mode and will stop the pump, and then return to OUT OF SERVICE mode.

The only operation which can be performed is to SWITCH the pump ON or OFF to determine its performance.
