Installation / Setup Procedure

ComTec GmbH 2-1

2. Installation / Setup Procedure

The delivery of a LW800 system includes a TX800 Discriminator / Transmitter module, a RX800

Receiver / Output module, a 50/125µm fiber cable of 2m in length and two AC adapters.

A spare low voltage connector is also provided. It might be used for connecting a custom-made

power supply e.g. a battery pack to power the TX800 module. A battery pack might be particularly

useful when the detector system and the TX800 respectively are at a high voltage potential. In

this case, the isolation capability of an AC adapter might not be sufficient.

Nowadays NiMH rechargeable battery cells are well available with a large capacity of e.g.

~2000mAh for Mignon types or ~8000mAh for Mono cells. Thus, considering the TX800's low

power consumption of approximately 200mA a battery pack consisting of 12 (x 1.2V = 14.4V)

NiMH Mignon cells will last for about 10 hours of operation. And, about 40 hours using fully

charged Mono cells. While 10 x 1.2V would be enough for a 12V supply the recommendation of

12 cells will assure safe operation even when the battery cells are getting near the discharged

state.

2.1. Cable connections

Connect the TX800 Discriminator / Transmitter Module and the RX800 Receiver / Output Module

with the supplied fiber cable.

The TX800 Discriminator / Transmitter Module uses a Class 1M LASER diode for optical signal

transmission. Please use appropriate LASER safety precautions when handling. The 850nm

LASER radiation is invisible to human eyes. Do not look directly into the LASER beam, as the

LASER radiation is potentially harmful.
