Function
(display) Description
OUT
(Setting for the
1st output)
OUT2 (Setting for
the 2nd output,
optional) Output switching mode for channel 2: flow or
temperature
Factory setting: flow
Temperature unit selection (°C/°F)
NOTE: Function only visible if switching mode
(MODE) is set to temperature in the 2nd output.
Switch output function:
hysteresis function NC contact or NO contact (see
diagram)
4…20 mA
Enter value 5…100% in increments of 1%.
Factory setting: 50%
Or optionally for SP2:
Enter value -15…85 °C (-5…185 °F) in increments
of
1 °C (1 °F) if the switching mode (MODE) is set to
temperature.
Factory setting: 55 °C (131 °F)
Take current flow rate as SP.
Enter value 0…95% in increments of 1%.
Factory setting: 40%
Note: The value has to be at least 5% smaller than
the switch point (SP or SP2).
Or optionally for RSP2:
Enter value -20…80 °C (-4…176 °F) in increments
of
1 °C (1 °F) if the switching mode (MODE) is set to
temperature.
Factory setting: 50 °C (122 °F)
Note: The value has to be at least 5 °C (9 °F)
smaller than the switch point 2 (SP2).
