3.1 Slip Ring Encoder SRE
Fig. 3.2 Slip Ring Encoder (SRE)
The SRE (ref. Fig. 3.2) is the core part of the detection system as it detects the
thermovoltage and rotational signal and ultimateley delivering the monitoring of the
engine.
The SRE is adapted to a speci c engine with a custom mounting board/ ange. This
ensures high compatibility across engine types and an easy dismount of the SRE
for maintenance. It’s highly rugged design ensures a trouble free operation under
typical conditions (refer to Chapter 2 General Technical Data) and it’s redundant
thermovoltage read-out satis es even high security demands.
Info: The shaft and the mounting  ange are determined, designed and manufactured
by motcom GmbH or by its authorized partners for each engine type. Only
in this case correct operation and trouble-free transmission of measurement
signals are guaranteed.
The connector-set for the socket at the SRE: Art. No. 9 300 12 10000 has the wiring
assignment as listed in Table 1, Chapter 12 Appendix, for the connector-set with
the Art. No. 9 30012 20000.

The Evaluator (Fig.3.3) consists of a IP66 compliant, shock resistant metallic case,
a LCD, three LEDs (Shut-down, Pre-Alarm, System Ready), four control keys
( , , , ) and one reset button .
The Evaluator can be operated between 0-70°C and 0-80% relative humidity,
suitable for installation close to the engine. It displays all measurement values and
parameters and is used for diagnostics of the BeCOMS® system.
The installation of the Evaluator is performed via two assembly rigs. If required, the
Evaluator can be mounted vibration-free.
Strain on plugs and cables must be avoided at any time.

The control keys of the Evaluator are made as lm-press buttons. Do not press
them with any sharp items like knifes, screw-drivers or ball-pens. Just touch the
buttons with a slight pressure by a ngertip.
The keypad can be wiped with a mild cleaning agent. Please never use a solvent!
After installation and commissioning by service technicians approved by motcom
GmbH, the settings of the Evaluator should not be changed. The Evaluator does
not require regular maintenance.
Note: Available Firmware updates are only to be applied by approved service
technicians.
Firmware updates are free of charge. Please contact motcom GmbH or an
authorized representative for details and further information.
