5.2 Ready indication

The signal relay is active when the pump is in operation or ready for opera-
tion.
See section 5.4 Functional diagram.

5.3 Operating indication

The signal relay is active as long as the pump is operating. If the pump is
stopped on the control panel, with the R100 or because of a fault, the signal
relay is deactivated and consequently gives a signal to an external control
system, e.g. a building management system.
See section 5.4 Functional diagram.
