Relay outputs
The two relay outputs can be configured for Max or Min alarms for one sensor or for
several sensors at the same time. Min and Max values are linked to the alarm limits
(thresholds) set for the different sensors. The relays (with changeover contacts) open or
close (depending on the connection) when the measurement exceeds or drops below an
alarm limit. (Fig. 11)

Maintenance
The instrument is designed for minimum maintenance. The instrument housing is IP54
(NEMA3). The sensor cable is specially made in PUR™ with a strong shield and extra
strands for long life. The sensor and the cable clamps are of the MatchClamp™ type to
guarantee no leaky contacts or distorted cables.
