2Safety
DANGER!
This section provides an overview of all the important safety aspects that ensure
protection of personnel, as well as safe and trouble-free device operation.
If these safety instructions are not complied with significant hazard can occur.
2.1 Responsibility of the owner
The device is used in commercial applications. Consequently the owner of the device is subject to the
legal occupational safety obligations, and subject to the safety, accident prevention, and
environmental protection regulations that are applicable for the device´s area of implementation.
2.2 Intended use
The device has been designed and constructed exclusively for the intended use described here.
Series TDP 1,2 are used for speed monitoring, for instance of electrical and mechanical drives,
hoisting gear, and conveying machines.
Claims of any type due to damage arising from non-intended use are excluded; the owner bears sole
responsibility for non-intended use.
2.3 Improper use
Do not use the device in potentially explosive areas.
The device must not be subjected to mechanical loads in addition to its own weight and
unavoidable vibration and shock loads that arise during normal operations.
Examples for non-permitted mechanical loads (incomplete list):
-Fastening transport or lifting tackle to the device, for example a crane hook to lift a
motor.
-Fastening packaging components to the device, for example ratchet straps, tarpaulins
etc.
-Using the device as a step, for example by people to climb onto a
motor.
It is not permitted to use the device in locations higher than 1000 m above sea level.
2.4 Personal protective equipment
Wear personal protective equipment such as safety shoes and safety clothing to minimise risks to
health and safety when carrying out work such as installation, disassembly or commissioning. Adhere
to all applicable statutory regulations as well as the rules and standards determined by the owner.
2.5 Personell
Installation and commissioning as well as disassembly routines must be carried out by skilled
technical staff only.

2.6 Special dangers
Residual risks that have been determined based on a risk analysis are cited below.
2.6.1 Electrical current
Danger of death from electricity!
There is an immediate danger of death from contact with live components. Damage to
the insulation or individual components can be lethal.
Therefore: If the insulation is damaged turn off and isolate the power supply
immediately; ensure the insulation is repaired. Before commencing any work on the
electrical installation turn off and isolate the power supply to the installation. Ensure
live components do not come into contact with moisture. Otherwise, this can lead to a
short-circuit.
Danger!
fahr!
2.6.2 Rotating shafts and hot surfaces
WARNING!
Risk of injury from rotating shafts and hot surfaces!
Touching rotating shafts can result in serious injuries.
Therefore: Do not tinker with moving parts/shafts or work on rotating shafts. Do not
open covers during operations. Ensure no parts are moving before opening any
covers. The encoder can become very hot when operated for longer periods of time.
There is a risk of burns on contact!
2.6.3 Ensure the power supply cannot be reconnected
DANGER!
Danger of death from unauthorized reconnection of the power supply!
There is a risk that the power supply will be reconnected without authorization when
carrying out work, for example when rectifying faults. This represents a serious risk to
the life of those in the danger zone.
Therefore: Turn off and isolate all power supplies to the equipment before
commencing work. Ensure the power supplies cannot be reconnected.

3.6 General technical data, electric implementation
Magnet system design
The magnet system of these machines consists of two permanent block magnets, developed especially
for these machines and manufactured in AINi Co alloy.
The direction of magnetization is determined by the material's optimum direction of magnetization. In
order to guarantee operation free of ageing problems, the permanent magnets are aged artificially until
they reach optimum remanent energy density.
CAUTION!
Short circuits should be avoided because of their bad effect on the commutator; any burn
marks can give rise to additional harmonics.
Magnetization, external effects
The machines are magnetised when mounted via an external power source.
The magnetising field strength required to saturate the permanent magnets is about 4000A / cm
CAUTION!
After magnetization, the machine's magnetic circuit must not be interrupted, otherwise a
voltage drop of approx. 25 % occurs. It is vital to follow precisely the dismantling
instructions of the machine (please ask for special leaflet, see page 32).
Any effect on the tacho voltage due to magnetic or electrical field stray is largely prevented by
strongly formed machine yoke.
Insulation
The standard insulation complies with Insulation Class B (VDE 0530). Special insulation types can
be provided to enable the tacho to operate in the following conditions:
Insulation Class F (ambient temperature to max. 100 °C). See temperature coefficient.
Humid and tropical condition
Limited resistance to acid and alkaline fumes Winding test: max. 1000 V on repeat test.

Voltage
The listed voltages are detailed in the technical tables for the different, available machine types.
Intermediate values and special voltages are possible (optional)
When values are lower than the listed voltages (<10 V) the listed power rating must be reduced to 1/50
(brush voltage drop). Use version G if voltage values below the listed values (<10 V) are required
when utilizing double tacho-generators.
Nominal voltage tolerance
The nominal voltage tolerance indicates the deviation of the set voltage from the nominal value. It is
obtained from the energy contents of the permanent magnets being used, which are also subject to
tolerance. This results in different values from machine to machine when setting the operating point.
The maximum tolerance is +5%. A tighter voltage tolerance ± 1% is possible.
Power available
The maximum available power given in the selection tables is always referred to the rated speed of
1000 rpm. Should this power be fully utilised, the user should note that the linearity error worsens
(approx. 0,5% at 1000 rpm). The maximum permissible current, which is given in the selection tables,
should not be exceeded at maximum permissible speed.
Connections, polarity
Connection: Single tacho to a 2-pole terminal board. Double tacho to two 2-pole terminal boards.
Terminal board bolt size M 4.
When rotation is clockwise, the machine (seen from DE) has terminal A 1 positive and terminal
A 2 negative polarity.
See page 29
Construction with 15 pin industry plug (optional).
Terminal box
1 terminal box for single tachos
2 terminal boxes for double tachos (Note: Double tacho with tapered shaft only, 1 terminal box).
