2.5 Safety awareness
In addition to the safety information contained in this operating manual and the
intended use, the following safety regulations shall be complied with:
▪Accident prevention, health regulations and safety regulations
▪Safety regulations for handling hazardous substances
▪Applicable standards, directives and laws
2.6 Software changes
The software has been specially created for this product and thoroughly tested.
Making changes or additions to the software or parts of the software is prohibited.
2.7 Explosion protection
!DANGER
Always observe the information on explosion protection given in this section when
operating the product in potentially explosive atmospheres.
The standard design of the KSB Leakage Sensor is not approved for use in potentially
explosive atmospheres.
The KSB Leakage Sensor may be used in potentially explosive atmospheres (II2GT5-
T1) provided that an inductive sensor1) approved for use in potentially explosive
atmospheres and a switching amplifier1) are used.
In this case, it must be ensured that the switching amplifier and the display unit are
located outside of the potentially explosive atmosphere. (ðSection9.2.2,Page30)
This operating manual’s additional sections containing information on use in
potentially explosive atmospheres must be observed. In addition, observe the
operating manuals provided by the manufacturers of components supplied with this
product that are marked as explosion-proof.
The KSB Leakage Sensor does not have its own marking (mechanical part: housing
parts and balance scale without inductive sensor) as it is considered an integral part
of the pump.
KSB Leakage Sensors fitted on pumps of a make other than KSB must not be used in
potentially explosive atmospheres.

5.1 Safety regulations
WARNING
Sensor housing and piping take on the same temperature as the fluid handled
Risk of burns!
▷Fit protective equipment/devices if necessary.
WARNING
Mechanical loads acting on the connections between pump (set) and sensor
Fluid could spurt out!
Burns, scalding!
▷Never subject the connections and piping between the pump (set) and sensor
housing to mechanical loads.
▷Verify proper installation of the sensor.
NOTE
Comply with all safety regulations of the corresponding pump (set).
5.2 Checks to be carried out prior to installation
NOTE
The KSB Leakage Sensor can be supplied pre-mounted on the pump (set) or
supplied but not fitted.
Observe the operating conditions of the pump (set).
Always contact the manufacturer if the device is to be used under ambient
conditions other than specified.
5.3 Installing the sensor
Observe the following:
▪No forces must act on the sensor housing via the leakage lines.
▪Do not insulate the piping to the leakage sensor. Ensure sufficient leakage
cooling.
▪The inside diameter of the leakage drain line must be equal to or greater than
that of the leakage inlet line. Otherwise large quantities of leakage can cause
backflow in the sensor housing and a malfunction of the sensor.
▪The inside diameter of the leakage lines must not be smaller than 6mm.
▪Never cover the vents in the upper housing half.

5.3.1 Installing a KSB Leakage Sensor that has been supplied but not fitted
üThe operating manual for the pump (set) is available.
üAssembly tools are available.
üAll safety instructions have been observed and carried out.
üThe pump (set) has been taken out of service and secured against unintentional
re-start.
üThe pump (set) has cooled down to room temperature.
1. Position sensor housing 105 on a level surface next to the pump, e.g. on the
baseplate of the pump.
ðSelect a sensor housing position that keeps the line leading from the pump
to the sensor as short as possible.
ðSelect a sensor housing position that keeps the distance to any hot pump
components and system components as large as possible.
ðIf the leakage inlet 8E is positioned on the same side as the leakage drain 8B,
the upper half of the sensor housing can be taken off, rotated by 180° and
mounted in this position. (ðSection7.3.2,Page25)
2. Mark the position of the drilled holes at the two lower recesses of sensor
housing 105 on the pump baseplate.
3. Carefully place aside sensor housing 105. Drill holes (M5) into the pump
baseplate.
4. Position the sensor housing again. Fasten it to the pump baseplate with
hexagon socket head cap screws 914.2.
5. Verify the levelling of sensor housing 105 with measuring instrument 690
(bullseye level). If necessary, undo hexagon socket head cap screws 914.2 and
level the sensor housing with suitable shims. Re-tighten hexagon socket head
cap screws 914.2.
6. Use the supplied compression fittings and L-pipe to connect the leakage drain
hole of the pump (set) with leakage inlet 8E of the sensor housing.
ðIf necessary, shorten the leakage line (pipe) accordingly.
7. Use the supplied compression fittings and L-pipe to connect the leakage drain
hole 8B of the sensor housing to the site-supplied leakage collector.
ðFit the leakage line with a continuously falling slope towards the site-
supplied leakage collector.
5.3.2 Installing a pre-mounted KSB Leakage Sensor
üThe operating manual for the pump (set) is available.
üAssembly tools are available.
üAll safety instructions have been observed and carried out.
üThe pump (set) has been taken out of service and secured against unintentional
re-start.
üThe pump (set) has cooled down to room temperature.
1. After the pump set has been installed, verify the levelling of sensor housing 105
with measuring instrument 690 (bullseye level). If necessary, loosen hexagon
socket head cap screws 914.2 and level the sensor housing with suitable shims.
Re-tighten hexagon socket head cap screws 914.2.
2. Use the supplied compression fittings and L-pipe to connect the leakage drain
hole 8B of the sensor housing to the site-supplied leakage collector.
ðFit the leakage line with a continuously falling slope towards the site-
supplied leakage collector.

5.5.2 Analog output
The analog output supplies a 4-20mA signal, indicating the averaged leakage rate
depending on the sensitivity level set via the DIP switches (ðSection5.4.4,Page19)
as per the following table.
