assembly if necessary.
2 Network sub-
voltage
• The network voltage has
fallen below 180VCA.
• The interface will reset when
the voltage rises over 209VCA
again for at least 6 seconds
3 temperature • Motor temperature too high
(+100°C)
• Motor temperature too low
(-20°C)

the voltage returns to a
normal value.
6 Motor sha jammed • Motor start-up impossible
• The motor has stopped
• Break the pump circuit
