> Failure of the measuring device
No sharp or heavy objects should be allowed to affect the cables. Avoid folding the cables.
> Damage or destruction of the cable, failure of the measuring device
1.3 Notes on CE Marking
The following apply to the induSENSOR DTD / MSC7401 / 7802 / 7602 series:
- EU Directive 2014/30/EU
- EU Directive 2011/65/EU
Products which carry the CE mark satisfy the requirements of the EU directives cited and the relevant appli-
cable harmonized European standards (EN). The measuring system is designed for use in industrial environ-
ments.
The EU Declaration of Conformity and the technical documentation are available to the responsible authori-
ties according to EU Directives.
1.4 Intended Use
- Das induSENSOR DTD / MSC7401 / 7802 / 7602 measuring system is designed for use in industrial
environments. It is used to control inductive displacement sensors based on the LVDT principle (Linear
Variable Differential Transformer) and for operation with LDR displacement sensors.
- The system must only be operated within the limits specified in the technical data, see 2.3.
- The system must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the system.
- Take additional precautions for safety and damage prevention in case of safety-related applications.

2. Functional Principle, Technical Data
2.1 Functional Principle
The DTD / MSC 7401 / 7802 / 7602 series are single- and multi-channel miniature sensor controllers for the
operation of inductive displacement sensors based on the LVDT principle (full bridge) and for half-bridge
sensors.
An electronic oscillator supplies the primary coil with an alternating current of constant frequency and ampli-
tude. For optimal control of the respective sensors, the frequency and the supply voltage can be set, see 5.
The demodulator electronics transforms the signal of the two (secondary) coils into the set output signal. With
the setting possibilities for zero point and gain, the user can adapt the equipment to the task to be performed,
see 5.
The output signal increases, when the plunger is moved into the sensor. If the reverse effective direction is
required (i.e. the signal becomes smaller when the plunger is inserted), replace the connections
Secondary + and Secondary -, or make the according setting in the controller, see 5.3.4.

2.2 Structure
A complete measuring channel consists of
- Sensor and controller (DTD, MSC7401 model)
- Two sensors and controllers (MSC7802 / 7602 models)
- Sensor cable
- Supply and output cable
Any type of half-bridge and full-bridge sensors can be connected to the amplifier electronics. However, if sen-
sors of other manufacturers are used you should check their functionality in conjunction with the controller.
MICRO-EPSILON recommends the inductive displacement sensors and gauging sensors of the induSENSOR
DTA and LDR series because they are optimally adjusted with the controller.

put cable. Avoid folding the cables
> Damage to or destruction of the sensor cable and/or controller
Do not bend more tightly than the minimum bending radius of the cables.
> Damage or destruction of the cables
> Failure of the measuring device
Check all plug-in connections for firm seating before starting operation.
iEnsure careful handling during installation and operation.
In addition with the DTD model:
iAvoid cyclic movements of the crimps and ferrite of the sensor cable. In the case of cyclic movements (e.g. use in a drag chain), fix the sensor cable additionally with suitable means.
