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.

Essential safety information

2.7 Safety information

English

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.
