Preventive Maintenance and Fault-finding

Reference Guide: SM6610, SM6615, SM6620 and SM6625 Satellite Modulators

Page 8-3

ST.RE.E10152.2

8.1 Introduction

This chapter provides the schedules and instructions, where applicable, for

routine inspection, cleaning and maintenance which should be performed

by an operator. There are also some basic fault-finding procedures to

follow in the event of a suspected failure of the SM66XX Satellite

Modulator.

8.2 Routine

Checks

8.2.1 Cooling

Fans

There are no routine checks associated with this equipment other than to

ensure that the unit is adequately cooled. This equipment must never be

operated unless the cooling fans are working; this should be checked

periodically. A fan fail alarm will be enunciated via the control interfaces if

any of the fans stop working.

CAUTION…

The fans contained within this unit are not fitted with insect/dust filters. Pay particular attention to the

environment in which it is going to be used.

8.2.2 Cleaning

Unplug the equipment from the supply before cleaning. Do not use liquid

or aerosol cleaners. Use a damp cloth for cleaning the exterior of the

Modulator.

8.3 Servicing

8.3.1 Conditions

Requiring

Servicing

WARNING…

DO NOT ATTEMPT TO SERVICE THIS PRODUCT AS OPENING OR REMOVING COVERS MAY

EXPOSE DANGEROUS VOLTAGES OR OTHER HAZARDS. REFER ALL SERVICING TO SERVICE

PERSONNEL WHO HAVE BEEN AUTHORISED BY TANDBERG TELEVISION.

The following is a list of conditions which may indicate the need for

servicing:
1.  When the power-supply cord or plug is damaged.
2.  If liquid has been spilled, or objects have fallen into the product.
3.  If the product has been exposed to rain or water.
4.  If the product does not operate normally by following the operating

instructions. Adjust only those controls that are covered by the

operating instructions, as an improper adjustment of other controls

may result in damage and will often require extensive work by a

qualified technician to restore the product to its normal operation.

5. If the product has been dropped or the case has been damaged.
