Mounting and Wiring
Important notes:
♦
The switch is to be installed
on horizontal pipes only!
♦
Installation on 1" NPT plastic pipe
is NOT recommended!
♦
Use a proper sealant
(we recommend Teflon® tape)
and always check for leaks
prior to system start-up!
♦
Never use the housing to thread
the unit! Always use only
an appropriately sized wrench!
♦
Never over-tighten the unit!
Mounting
♦
Apply tape seal
to the process connection thread
and mount the unit on a T-pipe
as shown on the left.
♦
After installation, make sure
the paddle is parallel
to the cutting face of the pipe
and the flow direction mark
is parallel to the pipe
and to the ground.
Cable selection
♦
Use only one flexible cable
with 2 or 3 multi-core wires
depending on contacts used.
♦
To ensure IP65 protection class,
use cable with outer diameter
5.5...6.5 mm. Other cable
diameters require changing
cable gland rubber sealing.
Wiring
♦
Open the protection head.
♦
Unscrew the cable gland and
remove the protection seal.
♦
Run the cable
through the cable gland nut,
rubber seal, and head entry.
♦
Wire the changeover contact
leads via the respective
ceramic base terminals
as shown on the left figure.
♦
Screw the cable gland nut
to fix the cable well.
♦
Close the head.
Important notes:
♦
Strictly observe
the relay contact ratings
given in 'Specifications'.
♦
Ensure the protection head
cable gland is securely sealed.
