1-3. Checking Fan Operation

The unit is provided with a fan. It is designed to turnautomatically when internal temperature rises over 80dC orDC output reaches 40 W. If there is any doubt that the fanor fan motor control circuit fails, check the fan operation asfollows.

Equipment Required. Electric Load

Hewlett-Packard HP6051A + HP60501B

1. Set the electric load to 8 A in the CC (constant current)mode.

2. Connect the electric load as follows and make sure thatthe fan starts up within ten minutes.

3. Disconnect the electric load after the fan turns andmake sure that the fan stops in the order of tenseconds.

SAFETY CHECK-OUT

After correcting the original service problem,perform the following safety checks beforereleasing the set to the customer :

Check the metal trim, “metallized” knobs,screws, and all other exposed metal parts for ACleakage. Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part toearth ground and from all exposed metal parts toany exposed metal part having a return tochassis, must not exceed 3.5 mA. Leakagecurrent can be measured by any one of threemethods.

1. A commercial leakage tester, such as theSimpson 229 or RCA WT-540A. Follow themanufacturers’ instructions to use theseinstruments.

2. A battery-operated AC milliammeter. TheData Precision 245 digital multimeter issuitable for this job.

3. Measuring the voltage drop across a resistorby means of a VOM or battery-operated ACvoltmeter. The “limit” indication is 5.25 V, soanalog meters must have an accurate low-voltage scale. The Simpson 250 and SanwaSH-63Trd are examples of a passive VOMthat is suitable. Nearly all battery operateddigital multimeters that have a 20 V AC rangeare suitable. (See Fig. A)
