STATUS-NOT-SET | Power-on-delay-(co)-yuzZjoo.dita
5.7 Power-on delay
With this function it is possible to delay the startup of the pump after
the power supply has been switched on. The purpose is to avoid
disturbing the main power network which could happen if several
pumps start up immediately when the power supply is switched on.

STATUS-NOT-SET | Dry-running-protection-(co)-yjADxMQ.dita
5.8 Dry-running protection
If the pump is running and the liquid level in the tank or pit becomes
lower than the dry-running level, the dry-running protection will stop
the pump to ensure that it is not damaged.
Dry-running protection is dependent on a feedback signal from a
level sensor installed in the tank or pit.
