3.1 General instructions for use of the instrument
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter "Connecting to
power supply")
• Tighten the cable gland or plug connector
• À½ÆÅÇÍÆÌÁÆ¿ÀÇÊÁÒÇÆ̹ÄÄÑƓÌÍÊÆÌÀ½ÀÇÍËÁÆ¿ËÇÌÀ¹ÌÌÀ½»¹ºÄ½

To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.

3.2 Mounting instructions
Mount NivoGuide 3100 in such a way that the distance to vessel
installations or to the vessel wall is at least 300 mm (12 in). In non-
metallic vessels, the distance to the vessel wall should be at least
500 mm (19.7 in).
During operation, the probe must not touch any installations or the
vessel wall. If necessary, fasten the probe end.
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
nearly down to the lowest point of the bottom. Keep in mind that
measurement all the way down to the tip of the probe may not be pos-

If this is not possible, use short sockets with small diameter.
Higher sockets or sockets with a bigger diameter can generally be
used.They can, however, increase the upper blocking distance (dead
band). Check if this is relevant for your measurement.

4.1 Connecting
The voltage supply and signal output are connected via the spring-
loaded terminals in the housing.
Connection to the display and adjustment module or to the interface
adapter is carried out via contact pins in the housing.
Information:
The terminal block is pluggable and can be removed from the
electronics. To do this, lift the terminal block with a small screwdriver
and pull it out. When reinserting the terminal block, you should hear it
snap in.
Proceed as follows:
1. Unscrew the housing lid
2. If a display and adjustment module is installed, remove it by turn-
ing it slightly to the left
3. Loosen compression nut of the cable gland and remove blind
plug
