6.2 Ready indication
The signal relay is active when the pump is in operation or ready for
operation.
See section 6.4 Functional diagram.
6.3 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 6.4 Functional diagram.
