1-10. Circuit Protective Elements
1-10. Circuit Protective Elements
The positive characteristic thermistor (for power supply) functions as a circuit protective element on the
AT-141, DPR-163, RC-86, IF-789A/789P (HKCU-901), FC-83 (HKCU-903) and LC-41 (HKCU-904)
boards of the unit. The thermistor increases the internal resistance and limits the current flowing to the
circuits when an overcurrent flows or when the ambient temperature increases and the element reaches
the specified temperature. If the elements operates, turn off the main power and inspect the HDCU
internal circuit. After removing the cause of the equipment abnormality and the temperature of the
element decreases, turn on the power again and operate the unit correctly. It takes about 1 minute for the
elements to cool down after the main power is turned off.

SAFETY CHECK-OUT
After correcting the original service problem,
perform the following safety checks before
releasing the set to the customer :
Check the metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC
leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to
earth ground and from all exposed metal parts to
any exposed metal part having a return to
chassis, must not exceed 3.5 mA. Leakage
current can be measured by any one of three
methods.
1. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The
Data Precision 245 digital multimeter is
suitable for this job.
3. Measuring the voltage drop across a resistor
by means of a VOM or battery-operated AC
voltmeter. The “limit” indication is 5.25 V, so
analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of a passive VOM
that is suitable. Nearly all battery operated
digital multimeters that have a 20 V AC range
are suitable. (See Fig. A)
