1.3 General function description
The rotary measuring system
•PSEN enc mx eCAM is an absolute multi-turn position measuring system with
synchronous serial interface (SSI).
•PSEN enc sx eCAM is an absolute single-turn position measuring system with
synchronous serial interface (SSI).
The measuring system consists of a redundant, dual-channel system, in which
optical and magnetic sensing units are arranged on a drive shaft, designed as a
hollow shaft or solid shaft.
1.3.1 Main features
●SSI interface, to output data from measuring channel 1
●SSI interface, to output data from measuring channel 2
●Measuring channel 1:
- Single-turn: optical single-turn sensing via code disk (transmitted light)
- Multi-turn: optical single-turn sensing via code disk (transmitted light) and
magnetic multi-turn sensing
●Measuring channel 2:
- Single-turn: magnetic single-turn sensing
- Multi-turn: magnetic single and multi-turn sensing
●Additional incremental interface
●Mechanically, the two systems are connected only by the common drive shaft and
the housing
●Measuring channels have a common voltage terminal, but are electrically isolated
internally via two separate power supplies
●A common drive shaft
●2 Installation Types:
- Hollow shaft version: PSEN enc m1 eCAM and PSEN enc s1 eCAM
- Solid shaft version: PSEN enc m2 eCAM and PSEN enc s2 eCAM
The optical system has greater accuracy due to the technology.
The magnetic sensing system is a fully-fledged second measuring channel and
operates independently from the first measuring channel. The two measuring systems
have their own SSI interfaces, which transmit the same data format.
The data from measuring channel 1 is also output via an incremental interface.

2.7 Safety information
Please note:
– Wiring work should only be carried out when the supply voltage is
switched off; the same applies when opening and closing electrical
connections.
– Do not undertake any welding operations if the measuring system is
already wired / switched on.
– An appropriate heating/cooling measure should be used at the
installation site to prevent the ambient temperature exceeding or falling
below the permitted limit values.
– The measuring system must be installed so that direct moisture cannot
affect the measuring system.
– Appropriate ventilation/venting or heating/cooling measures at the
installation site must prevent values falling below the dew point
(condensation).
– If an overvoltage of >36 VDC is applied inadvertently, the measuring system
must be inspected on site and the reasons/circumstances stated.
– Checks must examine the potential hazards arising from interaction
with other systems and devices which are or will be installed in the
vicinity. It is the user’s responsibility to take appropriate measures.
– The supply voltage must be protected with a fuse appropriate for the
cable cross section.
– Cables must be suitable for the relevant temperature range.
– The measuring system should not be operated if it is defective.
– Ensure that the installation environment is protected from aggressive
media (acids etc.).
– Shocks to the shaft (e.g. hammer blows) should be avoided during
installation.
– The measuring system must not be opened.
– The nameplate specifies the technical properties of the measuring
system. If the nameplate is no longer legible or is missing altogether,
the measuring system must no longer be put into service.

4 Assembly
4.1 Solid shaft version
The measuring system is connected to the drive shaft via an elastic coupling. The
coupling absorbs any deviations in the axial and radial direction between the
measuring system and drive shaft. This prevents excessive load on the bearing.
The centering collar with selective fit is used for centering in relation to the shaft. The
device is fixed to the machine using three screws in the flange.
All the fixing screws must be secured to stop them coming loose unintentionally.
4.1.1 Requirements
As the installation is application-dependent, the following instructions do not
claim to be exhaustive.
An appropriate coupling with positive-locking connection must be used in
the application.
The instructions and installation specifications provided by the coupling
manufacturer must be observed.
In particular you must ensure that
– the coupling is suitable for the specified speed and the potential axial
offset
– the device must be installed on a greaseless shaft
– the coupling and measuring system must not have an axial load
– the clamping screws must be tightened with the torque defined by the
coupling manufacturer
– the coupling screws must be secured to stop them coming loose
unintentionally.
The coupling fixing should prevent axial slippage of the measuring
system on the drive shaft, see Figure 2, 1 .
Positive locking using a parallel key/groove combination (Fig. 2, 2 )
should prevent radial slippage of the measuring system on the drive
shaft; a coupling with groove should be used for this purpose.

4.2 Hollow shaft version
4.2.1 Requirements
As the installation is application-dependent, the following instructions do not
claim to be exhaustive.
The measuring system should be installed on a greaseless shaft.
The clamping ring fixing should prevent axial slippage of the measuring
system on the drive shaft, see Figure 3.
Additional measures may be required to prevent axial slippage of the
measuring system.
The clamping of the measuring system must not have an axial load.
The screw on the clamping ring must be tightened to 3 Nm using a
torque wrench.
The screw on the clamping ring must be secured to stop it coming loose
unintentionally.
Positive locking using a parallel key/groove combination should prevent
radial slippage of the measuring system on the drive shaft; the
measuring system must be fixed to the drive side using a dowel pin, see
Fig. 4.
