Danger or injury to the operator or damage to the property
•Connection to power supply must be performed in accordance with safety
instructions for electrical facilities and performed only by qualified personnel.
•Any alteration, reconstruction or extension of the sensor is not allowed!
•The sensor must be operated only within values specified in the catalog or
datasheet.
•The danger of personal injury and danger of property damage due to a
malfunction of the sensor in machines or systems must be excluded by
additional safety measures.
•In safety-relevant applications, additional facilities shall be provided for
maintaining safety and preventing damage.
•Check whether the protection class of the sensor is suitable for the
application.
Risk of crushing and cutting injury due to pre-tensioned spring being released
from housing when opened!
•Do not open the sensor.
Risk of cutting injury due to uncontrolled retraction of the tape
•Do not damage the measuring tape!
•Do not let the measuring tape spring back uncontrolled!
•Do not exceed the maximum tape extension range!
•Do not bend the measuring tape!
•Do not let the measuring tape be dragged on objects!
Mechanical damage or destruction of the sensor
•Avoid impact and shock to the sensor.
•Do not allow the measuring tape to spring back uncontrolled.
•Do not pull out the measuring tape beyond the range of the sensor.
Malfunction due to the accumulation of dirt on the measuring tape
•Do not oil or lubricate the measuring tape.

positape®Tape Extension Position Sensor with an integrated inclinometer are used to measure both linear
and inclination position at the same time. Both output parameters – linear position and inclination – are
independent of each other.
The ranges for the measuring length and inclination as well as the information on environmental compatibility
and connection data given in the data sheet must be observed. The sensor is used as intended if it is
operated within its specified technical data and ambient conditions.
The installation and operating instructions supplied with the unit must be observed and all maintenance and
service work must be carried out. The data sheet of the respective sensor is part of this instruction manual.
If not available, it may be requested by stating the respective model number.
The sensor must not be improperly mounted, operated or serviced. In addition, operation of the sensor in
faulty condition is prohibited.

2 Transport and storage
Risk of damage to the measuring tape
•Do not lift the sensor by the tape.
Observe storage and transport temperatures according to the operating temperature (see data sheet)
Max. rel. humidity 60%, condensation must be excluded
The device must be secured against slipping and tipping during transport.
Unpacking
Do not unpack sensor by holding it at the tape or tape stop.
Shipment damages
Check sensor immediately for shipment damage. In case of any damage or equipment not operating
appropriately, please contact your supplier. Avoid bending the tape stop while packing the sensor.

3.1 Mechanical installation
Risk of injury from touching the moving measuring tape or moving parts
during operation
•Operate the sensor only with a suitable protective device (eg. tape cover) to
prevent injury!
Choice of installation position
•Select a protected installation position for the measuring tape.
This prevents damage of the measuring tape.
•Preferably mount the sensor with the tape outlet pointing downwards.
This prevents liquids from entering through the tape outlet.
•Screw the sensor onto a flat surface or provide a three-point mounting.
This avoids distortion and damage to the sensor.
Fitting the sensor
Depending upon the sensor model, holes in the base plate or threads in the sensor housing enable
attachment of the sensor. Dimensions required are listed in the data sheet and the catalog.
Tape attachment device
For fastening the tape clip the 5 mm dia. bore is provided.
Damage to the measuring tape due to incorrect installation
•Prevent the measuring tape from binding.
•Ensure sensor is installed and aligned correctly to prevent damage to tape. Where
required use a tape diverting pulley WBR1.
Damage to the measuring tape due to an axial twist
•Do not exceed the maximum twist of 90° of the measurement tape
•A single tape twist of 90° is possible. Before twisting the tape, a distance of at least
30 cm from the tape outlet must be kept in axial direction. While retracting the tape,
it must be twisted back at the distance of at least 30 cm before the tape entirely
enters the tape outlet.

Damage to the measuring tape due to the tape misalignment
•Tape travel should only be axial to the tape outlet - no misalignment is allowed!
•Tape misalignment shortens service life of sensor and causes error in
measurement. Warranty will not be granted for damage caused by misalignment.
correct incorrect
If tape travel axial to the tape outlet is not possible, a tape guide wheel must be used in
order to divert the tape. The deflection is possible only in one axis - on the flat side.
Pulley wheels with the diameter of >15 mm are recommended (see chapter
“Accessories” in the catalog positape®).
