12.5 MOUNTING THE SENSOR LA25S INTO THE FLOW CHAMBER LS25
If individual components are assembled by the customer, the sensor is mounted as follows:
•
Insert the sensor with the pre-assembled union nut and the pre-assembled pressure and cutting
ring into the screw fitting and tighten the union nut. First tighten the nut hand-tight, then tighten
the nut exactly 1 1/4 turn with a flat spanner. The nut is then correctly fitted.
13 SUPPLY CONNECTIONS
13.1 ELECTRICAL CONNECTIONS
W A R N I N G !
Incorrect supply voltage may destroy the equipment. Please take
care of the correct voltage as indicated on the type plate!
The supply voltage may vary from the indication on the type plate
by max. ± 10%.
N O T E !
When setting high-power electrical units with nominal voltages of
up to 1000V, attention must be paid to the requirement of IEC 364
(DIN VDE 0100) as well as the associated standards and
stipulations!
The electronic controller
LA1.1 are equipped with a mains selector switch S3 for 230/115 V. At works,
this selector switch is adjusted to 230 V. Check the desired voltage before starting and, if necessary,
change the selector switch by using a screw driver.
The electronic controller
LA1.4 in 24 V version are suitable for both, constant voltage and alternating
voltage.
The sensor cable should not be too short at the mounting fitting, so that the sensor can be easily
disassembled during inspection or cleaning.
N O T E !
Only the sensor types LA1S and LA25S provide a line break
control.
N O T E !
The connection cable of the LA1S or LA25S sensor is a standard
2-wire cable and can be extended up to 100 m via standard
terminals if required.
The connection cable of the old sensors LA1, LA25 and LA1-H is a
special HF cable which must not be extended and connected to
standard terminals, otherwise the cable shielding will be
interrupted.
