FAULT REPAIR PROCEDURES

8.POWER SUPPLY FAULT

This section explains the fault repair procedure when any of the faults shown in Table 5-10occur.

Table 5-10 PWR Supply Fault Situation

FAULTY SITUATION	REFERENCE SECTION

Fuse Blown Fault	Section 8.2, Fuse Blown Fault

Circuit Breaker OFF, Fault in PWR Supply	Section 8.3, Circuit Breaker OFF Fault in PWR Supply

Fault of Alarm Lamps on PWR Supply	Section 8.4, Fault of Alarm Lamps on PWR Supply

8.1Check Point

When repairing a power supply fault, consider the following items:

(1)Before checking the system, check the rectifier, battery, and power cables.

(2)The PWR circuit card is equipped with the circuits to supply ringing signal and howler tone. When a fault occurs that causes the bell of the telephone not to ring, or howler tone cannot be heard, etc., check the alarm lamp on the PWR circuit card.

(3)Figure 5-13through Figure 5-15show the block diagrams for the power supply to each module.
