1 Safety
1.1 Definition of Warnings
DANGER!
Hint for possible dangerous situation. Ignoring the security terms
may cause death or serious injury.
WARNING!
Hint for possible dangerous situation.
Ignoring the security terms may cause injury.
CAUTION!
Hint for possible damage of property, if the corresponding protec-
tive measure were disregarded.
Further information
1.2 General Warnings
The system startup has to be carried out by trained qualified personnel, who is able
to evaluate the potential risks. All chapters of this instruction manual had to be read
and fully understood before startup.
On non-observance it’s not possible to assert a claim for the incurred losses from
the manufacturer. Any changes to the system, except those described in the
instruction manual and customer documentation, will invalidate any warranty.
DANGER!
Risk of Injury by Incorrect Installation
Incorrect installation can cause injury to persons directly while the
installation or during the subsequent startup
Note the Mounting Hint (see chapter 4, installation
instruction)
The system startup has to be carried out by instructed qualified
personnel that’s familiar with
– the professional handling of security relevant components,
–the valid regulations for operational safety und rules for acci-
dent prevention.
DANGER!
Risk of Injury by Unintentional Startup
Rotating or moving of parts by inadvertent startup of the machine
can cause injury .
During all mounting, demounting or repairing the system has to be
powered-off. Note the mounting instructions.
4 11021, 1, en_US
DANGER!
Risk of Injury by Movable Parts
While normal operation, as well as inadvertent loosening of parts
of the telemetry system during operation, present persons may be
injured if protective equipment is absent.
Check the safety function of the protective equipment particularly
– before each startup
–after each replacement of a component
– after a longer standstill
– after each defect
Independent thereof the safety function of the protective equip-
ment must be checked in suitable time intervals as part of the
maintenance work!
WARNING!
Risk of Burn Injury
While operation the sensor signal amplifier and the stator antenna
may become warm.
Avoid contact.
CAUTION!
Risk of Property Damage
If the connectors disconnected / connected while the
system is powered on the telemetry system as well as the
connected devices can be damaged.
Plug connectors must not be disconnected / connected
when the system is powered on.
11021, 1, en_US 5
2 Conventional Usage
Sensor telemetry systems are used for contact-free data and power transfer from
passive and active sensors (e.g. on rotating shafts).
DANGER!
Risk of Subsequent Damages caused by Malfunctions
If the telemetry system is used for controlling or regulating func-
tions it is not conceive for, subsequent damages up to injury to
persons can be caused.
The delivered system has to be used exclusively used for
the purpose for which it was ordered.
The operator must take care of his health and safety.
The operator of the equipment must prevent subsequent errors
following faulty measuring results. This is particularly necessary if
the telemetry system is used in controlling or regulating functions.
The customer, as the builder of a system with an integrated sensor tele-
metry system, is responsible for the correct and conform operation and also
assumes the responsibility for ensuring that the system at start-up com-
plies with all provisions of Directives 2014/53/EU and 2014/35/EU.
A telemetry system normally contains:
nEvaluation unit
nStator antenna
nRotor antenna
nSensor signal amplifier
nHF cable
For the detailed purchased parts package of the delivered tele-
metry system mind the corresponding shipping ticket.

NOTICE!
Possible Damage to the Rotor Electronics while soldering
A soldering that is too long or too hot can damage the sensor
signal amplifier. Keep soldering as short as possible. If necessary,
allow to cool.
NOTICE!
Damaging of Electronic
Condensation may cause unwanted contact between the pins
To prevent any effects of condensation the pin connections must
be waterproofed!
The sensor signal amplifier must be grounded by connecting the
GND pin to the rotor .
