COMMISSIONING AND OPERATION (Fig. 3)
The green "Power on" light on the front panel of the unit indicates voltage is present while a yellow "Pump on" lamp indicates that the
pump is operating. When the unit is plugged in, the green and yellow lights will turn on. the yellow light indicates that the pump has
started (Fig. 3 / A); it remains in operation for a few seconds to pressurize the system. If this time is not sufficient, the red light comes
on, in this case hold down the red button Restart and wait until water comes out of an opened sampling point. After closing the
sampling point, the device switches off the pump and then remains in standby mode; the green light stays on and the device is ready
to carry out all further command and control steps in complete autonomy (Fig. 3 / B). When opening a sampling point, the device
switches on the pump; This remains in operation until the sampling point is closed again (Fig. 3 / A). After closing the sampling point,
the device restores the maximum pressure in the system, switches off the pump and returns to standby mode (Fig. 3 / B). If there is a
lack of water during priming, the unit switches off the pump, signals it with the red light (Fig. 3 / C) and thus protects it from running
dry. Once the fault that caused the blockage is eliminated, it is sufficient to press the red "Restart" button to resume normal
operation. In the case of a temporary interruption of the power supply, the device restarts automatically as soon as the power returns.
PROBLEMS
•
The pump does not start.
•
The pump does not turn on.
•
The pump runs intermittently.
•
The pump does not turn off.
•
The pump is blocked.
MAIN CAUSE
Faulty power connection.
The water column is too high.
Water loss of the system less than the minimum flow.
Water loss in the system greater than the minimum flow.
Priming problems.
