Fig. 68
Slide the scale holder (with the
17.
affixed scale) into the guide of
the plastic housing. (Fig. 68).
Note direction of flow (lower
scale value toward the input side
of the device).
Loosen, then remove the socket
18.
from the switch contact and con-
nect a continuity meter or other
suitable test equipment. Note
the pin assignment. For Nor-
mally Open Contact pin 1 and
pin 2, for Change Over Contact
pin 1 and pin 3.
Loosen the set screw of the
19.
switch contact so that it can still
move freely.
Push the switch contact slowly
20.
against the direction of flow until
the contact closes. Then slowly
move the switch contact in the
direction of flow until the contact
opens. Proceed as precisely as
possible, as this affects the
measurement accuracy of the
device.

Secure the switch contact with
21.
the locking screws, observing
the proper tightening torque
( Ä Chapter 11.1 "Tightening
torque of screws" on page 85)
and ensuring that the switch
contact position does not
change. The arrow on the switch
contact rating plate should now
be in line with the first tick mark
of the positioning aid (scale on
the guide rail) respectively, the
body scale. If this is not the
case, the switch contact rating
plate or the positioning aid and
body scale must be removed
and repositioned. Parallax errors
must be avoided.
Loosen the set screws of the
22.
switch contact and position on a
tick mark in the middle of the
body scale, then lock the set
screws of the switch contact,
observing proper tightening
torque. ( Ä Chapter 11.1 "Tight-
ening torque of screws"
on page 85)
Hold the device vertically and,
23.
using the test rod, move the float
in the flow direction until the
switch contact switches (con-
tinuity meter). Then slowly move
the float back to the starting
position and, using the continuity
meter, determine at which scale
value the switch contact cuts off.
