| SYMBOL | WARNING | NATURE AND SOURCE OF THE DANGER |
|---|---|---|
| DANGER | Danger of death or injury to staff. | |
| WARNING | Potentially hazardous situation that could result in serious |
injuries or even death.
| NOTE| Tips and information for users.
1.2. INTENDED USE
| DANGER| In the event of incorrect use!
---|---|---
- Level probes are used to convert a hydro static pressure into a standardised electrical signal.
- The level probes in the various series referred to have been developed for applications measuring the relative or absolute pressure of water or fill levels depending on the type of probe.
- Make sure that the device is suitable for your correspond ding application. Please get in touch with your direct sales contact if you are unsure of any thing.
- Please refer to the relevant data sheet and agreed specifications for information about the level probe’s features.
- The technical specifications listed in the data sheet are only binding insofar as no other agreements have been made.
- The liquids used as measuring media must be compatible with the materials specified in the data sheet that come into contact with the media.
1.3. STAFF QUALIFICATIONS
The product must only be assembled, installed, put into operation, operated,
maintained, taken out of operation and disposed of by technically trained
staff.

MOUNTING
| DANGER| Danger of death by electrocution, pressure discharge or leaking
media!
The device must only be installed on systems when they are not pressurized or
connected to a power supply.
---|---|---
| DANGER| Danger of death in the event of incorrect installation!
The device must only be installed by specialist personnel who have read and
understood these operating instructions.
Follow the national standards and safety regulations during the assembly and
installation of the device.
3.1. INSTALLATION AND SAFETY INFORMATION
Only operate the level probe within its technical performance limits. You can
find these on the label, in the data sheet or in the specifications. The
device must not be operated for long periods in its overload range as this can
damage it.
The measuring medium must not be permitted to ice up.
Ensure that the material used for the selected level probe, including the
associated seals, is suitable for the medium to be measured.
As standard, level probes are delivered without accessories such as mounting
materials.
Avoid electrochemical voltage potentials.
DO NOT use the device to perform safety functions.
Do not remove the packaging until immediately before installation to avoid
damaging the diaphragm and/or the thread.
The output signal may be dependent on the installation position. Always
tighten the transmitter to the manufacturers’ instructions
Feed the cable output on pressure transmitters with cable into a dry terminal
box.
Avoid excessive tensile loads on the cable connections.
Make sure the holes in the end cap are free from impurities/dirt.
3.3. MECHANICAL INSTALLATION
Installation of screw able level probe with pressure connection
Before installation, make sure that the seal surfaces on the device and the
measuring point are clean and undamaged.
Make sure that the seal is intact and is in its intended position. Check that
the seal specifications correspond with the environment where it will be used.
Make sure that you do not damage the diaphragm. Front flush versions are to be
treated with particular caution.
Use suitable tools for installing the device.
Tighten the device with the appropriate torque.
Follow the instructions below to ensure optimum installation:
- Make sure that the seal surface seals correctly.
- Screw the device into the corresponding thread by hand.
- Using a suitable torque wrench on the spanner flats, tighten the device into place.
Install the device in such a way that it cannot be exposed to any prohibited mechanical tension. This could have a negative effect on the zero point and/or the characteristic lines.
3.4. ELECTRICAL INSTALLATION
Connect the device according to the electrical connections on the label or the
specification.
Prevent the cable from kinking.
The following minimum bending radius’s must be adhered to when installing the
cable:
Minimum bending radius for cables without capillary:
permanent installation: 6-fold cable diameter
flexible usage: 12-fold cable diameter
Minimum bending radius for cables with capillary:
15-fold cable diameter
Ensure adequate earthing via the cable shield.
For reference devices (relative pressure versions, PR), make sure there is
adequate, dry ventilation.
Make sure the cable is mounted securely, e.g. by using an additional retaining
cable, for cable lengths > 50 m.

- Ambient temperature too high/low
Action:
- Contact the manufacturer and, if necessary, replace the device
- Keep to the permitted temperatures given in the data sheet
SIGNAL SPAN DECLINES/IS TOO LOW
Possible cause:
- Mechanical overload
- Abrasive/aggressive medium; corrosion on the diaphragm/pressure connection
Action:
- Contact the manufacturer
CONSISTENT OUTPUT SIGNAL WHEN PRESSURE CHANGES
Possible cause:
- Mechanical overload
- Electrical fault
Action:
- Replace the device; if the fault occurs again, contact the manufacturer
NO OUTPUT SIGNAL
Possible cause:
- No supply voltage
- Device connected incorrectly
- Broken cable
Action:
- Check the supply voltage
- Correct connection in accordance with the electrical connections

SERVICING AND REPAIRS
6.1. MAINTENANCE
KELLER products require no maintenance and, if used in accordance with the
specifications, are fault free.
6.2. RECALIBRATION
Depending on the conditions in the area in which the device is used, its zero
point or signal span may change over time, causing an incorrect output signal.
We recommend that highly accurate devices with an accuracy of < 0,1 %FS are
periodically re calibrated or have their zero point adjusted.
6.3. RETURNS
Before returning a device for re calibration or repair, it must be thoroughly
cleaned and securely packaged. For faulty devices, use the KELLER returns form
and describe the fault in as much detail as possible.
If your device has come into contact with harmful substances, you must
