Service mode

You can use parameters P4016 to P4019 to set the pumps in service mode respectively.
When a pump is in service mode, the inverter locks the corresponding relay, which allows
you to perform troubleshooting of this pump without interrupting the operation of other pumps.
Danger to life due to unconnected low-voltage circuit breakers
If a pump is not connected to the mains and inverter through a low-voltage circuit breaker,
troubleshooting the pump in service mode can result in electric shock and unexpected
movement of the pump, causing serious personal injury or death.
• Make sure that all pumps are connected to the mains and inverter through low-voltage
