4.4.8 RELAY (OPTION)
The parameter definition of the limit contacts is completed within this function. Two
limit values are entered for each relay : 1 -, 1 + and 2 -, 2 +. The transmitter also has
the option to invert the relays and to set a delay time between 0 and 180 seconds.
This delay shall prevent the relays from being activated too quickly. If the measured
value exeeds a limit value, the transmitter will wait for the designated delay time before
activating the relay. If the value does not exceed the limit value after the delay time,
the relay will not be activated.
The unit and decimal point for level, distance, volume or temperature are
activated within this option as selected within the "UNIT" menu (see section
4.4.2).
The following conditions must be observed: 1-
≤ 1+, 2- ≤ 2+.
 Relay 1 : Non inverted with thresholds of 2 and 4 m

and no delay.
 Relay 2 : Inverted with thresholds of 6 and 8 m

and delay of 2 Sec.
1- and 2- = the low settings for both relays
1+ and 2+ = the high settings for both relays
