Output Transistor Replacement
Check Fuse First If all of the transistor outputs fail to work, check the 1A fuse shown in Figures 17 & 18.
Also check to be sure that a 10–30 VDC power supply is connected to TB 11, Figure 6.
Correct Problems Chips will most likely be damaged by one of two events:
• A short circuit connected to one of the transistor outputs.
• A load exceeding 50 mA connected to one of the transistor outputs.
Before replacing a transistor output chip, fix the problem that damaged it.
Proper Placement When replacing a chip, be sure that all of the pins are properly seated in the socket.
Position the notch on the end of the chip as shown below.
