MODES OF OPERATION
INITIAL START UP
SELF TEST OF LEDS
When the pump is plugged into the power supply, a self-test is conducted on
the LEDs, during which all the LEDs will light up in sequence for a few seconds.
INITIAL PRIMING
The pump will automatically be in
AUTO
mode set to
ON
.
There may be three possible conditions:
1.
Flow is present but with low pressure
: The pump exits the priming phase and
starts normal operation.
2.
Pressure is present but with no flow
: After 10 sec in this condition the pump
will switch itself off.
3.
No flow and no pressure
: The pump will switch itself off and the Dry-running
error will be displayed after about 3 minutes, indicated by the red LED in
SET-ALARM. Eliminate the cause and reset the alarm see 3).
OPERATION WITH CUT-OUT DISABLED (FACTORY SETTING)
CUT-OUT disabled means the following response occurs:
• The pump is activated if there is flow or pressure is absent, pressure is
less than CUT IN (in 10 secs).
• The pump will stop if pressure is present but flow is absent
continuously for 10 seconds.
The CUT OUT LED will be switched off during normal operation. To change the
setting see Mode Selection on page 10.
NORMAL OPERATION WITH CUT-OUT ENABLED
CUT-OUT enabled means the following:
• The pump will be activated if the pressure is less than the CUT IN
pressure.
• The pump will be stopped if the pressure is higher than the CUT OUT
pressure.
The CUT OUT will be switched on during normal operation. To modify the
setting see Mode Selection on page 10.
Stop the pump by switching off the power supply. If the water supply is
finished, disconnect the plug and switch off the pump. Avoid dry running.
