9 MAINTENANCE, SPARES, REPAIR AND SERVICING

The DSE2157 is designed to be Fit and Forget. As such, there are no user serviceable parts. In the

case of malfunction you should contact your original equipment supplier (OEM).

11 DISPOSAL

11.1 WEEE (WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT)

Directive 2002/96/EC

If you use electrical and electronic equipment you must store, collect, treat,

recycle and dispose of WEEE separately from your other waste.

11.2 ROHS (RESTRICTION OF HAZARDOUS SUBSTANCES

Directive 2002/95/EC:2006

To remove specified hazardous substances (Lead, Mercury, Hexavalent Chromium, Cadmium, PBB &

PBDE´s)

Exemption Note: Category 9. (Monitoring & Control Instruments) as defined in Annex 1B of the WEEE

directive will be exempt from the RoHS legislation. This was confirmed in the August 2005 UK´s

Department of Trade and Industry RoHS REGULATIONS Guide (Para 11).

Despite this exemption DSE has been carefully removing all non RoHS compliant components from

our supply chain and products.

When this is completed a Lead Free & RoHS compatible manufacturing process will be phased into

DSE production.

This is a process that is almost complete and is being phased through different product groups.

Suggestion

Ensure the host controller is correctly

configured to send signals to the 2157

Check polarity and size of the connected DC

supply are within the specifications of the

DSE2157

This means the the communications link to the

host controller has been lost.

Check the connection of the DSEnet paying

particular attention to the cable type being used

and the positioning of the termination resistors.
