Electrical connection
The temperature sensors are
mounted in the terminals of the
calculator as shown above. Jumpers
are used when mounting 2-wire
sensors.
In connection with flow sensors
V1 and V2, the below-mentioned
colours are used for connection of
ULTRAFLOW® and electronic pick-up
units.
Flow sensors with Reed switch
output must be connected
to terminals 11-10 and 11-69,
respectively.
