PJRL250 Technical and Maintenance Manual

R.V.R. Elettronica S.r.l. (Bo)

  Pag. 26

This section provides general maintenance information and electrical

adjustment procedures for the PJRL250 Amplifier.

Maintenance is divided into categories dependent upon the complexity of the

procedure and the test equipment required to complete the maintenance.

4.1 SAFETY CONSIDERATIONS

WARNING! WARNING! WARNING! WARNING! WARING! WARNING! WARNING! WARNING!

When the amplifier is operated with the top cover removed,

hazardous voltages are accessible on the AC line voltage selector and

heavy currents are accessible on the exposed terminals of the power

supply filter capacitor and power transistors mounted on the RF

amplifier heat sink assembly.

Use the insulated tuning tool provided for any adjustment and do not

touch any component within the amplifier when power is applied.

Ensure all primary power is disconnected from the amplifier before

attempting equipment maintenance.

FIRST LEVEL MAINTENANCE

4.2 ORDINARY MAINTENANCE

The only regular maintenance needed by PJRL250, is the periodic

replacement of the blowers, and the cleaning of dust filters and any dust

accumulated inside the amplifier.

The time between overhauling of the blowers depends upon several environmental

factors, temperature, humidity, dust pollution etc.

Blowers should be checked every 6 months and replaced if noisy. They should

be replaced any way after 18 months of service.

SECOND LEVEL MAINTENANCE

4.3 CARDS SUBSTITUTION

This section contains useful information for card replacement.

WARNING! TO RE-INSTALL THE CARDS IS ENOUGH TO EXECUTE

OPERATIONS SEQUENCE IN THE OPPOSITE WAY.

4.4 POWER SUPPLY REPLACEMENT

1)

Open the top cover.

2)

Take note of the wiring of J2, J3, J4, and J5 Low Pass

Filter's connectors.
