Connecting the internal relays
Statox 503 has three relays, each equipped with one make and one break contact. Two relays monitor
alarm threshold exceeding, one system failure.
System failure relay: The SF-relay coil is always active and drops out in case of a system
failure or voltage drop.
The alarm relay parameters can be set in the main menu. The SF-relay settings cannot be changed.
