1. Selection of the monitored medium:
Factory setting: Monitoring of liquids. For monitoring of gases: Link
terminals 23 / 24.
2. Setting of the power-on delay time:
Factory setting: Power-on delay time = 10 s. To define other times
for t1: Connect an external resistor (R) between the terminals 22
and 23.
t1 [s] 15 20 25 30 35 40 45 50 55 60 65 70 75 80
R [kΩ] 10 18 27 39 47 56 68 82 100 120 150 180 220 270
3. Apply the operating voltage. After the power-on delay time has
elapsed, the unit is ready for operation, (during this time the out-
put relay is energised).
4. Set the preset flow and keep it constant. Turn the setting poten-
tiometer (2) until a green LED lights. The farther the green LED lit is
away from the yellow LED, the safer is the adjustment (excess gain
for flow or temperature fluctuations).
5. Set the setting potentiometer for the temperature monitoring (3) to
the requested limit temperature.
