5.3.3. RELAY OUTPUT
P13: - - - a Relay function
a Relay function Also set:
0 DIFFERENTIAL LEVEL CONTROL
(Hysteresis control)
Relay is energised if the measured or
calculated value exceeds the value set in P14
Relay is de-energised if the measured or
calculated value descends under the value set
in P15

P14, P15
There is a need to set (in level
min 20mm) hysteresis between
P14 and P15
P14 > P15 – normal operation
P14 < P15 – inverted operation
1 Relay is energised in case of Echo Loss -
2 Relay is de-energised in case of Echo Loss -

Used for open channel flow metering.
A 140 msec pulse is generated every 1, 10,
100, 1.000 or 10.000 m
