Appendix A - Fault Codes
NOTE: Although many of the Possible Causes of the Err Codes are digital IC’s, their failure rates are very
low. Eliminate other possibilities (such as IC sockets, open pull up resistors or shorted bypass capacitors)
before changing them.
ACC CODES MEANING
FS Monopolar Footswitch Shorted.
LH Left Handswitched Monopolar
Accessory Shorted.
rH Right Handswitched Monopolar
Accessory Shorted.
bP Bipolar Accessory Shorted.
CP “xx” Control Panel key
Note: “xx” displayed in
Bipolar Power window corresponds
to the stuck key using Figure 2.1 as
a reference. Multiple keys show as “88”.
POSSIBLE CAUSES
-Monopolar footswitch pressed
while turning power on.
-Faulty ribbon cable or connector.
-Shorted Footswitch.
-Shorted bypass capacitors or open pull up
resistors on control lines.
-A3U11 Failure (8255).
-Left Handswitched Accessory pressed while
turning power on.
-Shorted Left Handswitched Accessory
-Faulty ribbon cable or connector.
-A5 U2 or U3 shorted.
-Shorted bypass capacitors or open pull up
resistors on control lines.
-A3U11 Failure (8255).
-Right Handswitched Accessory pressed
while
turning power on.
-Shorted Right Handswitched Accessory.
-Faulty ribbon cable or connector.
-A5 U5 or U6 shorted.
-Shorted bypass capacitors or open pull up
resistors on control lines.
-A3U11 Failure (8255).
-Bipolar Accessory pressed while turning
power on.
-Shorted Bipolar Accessory.
-Faulty ribbon cable or connector
-A5 U1 shorted.
-Shorted bypass capacitors or open pull up
resistors on control lines.
-A3U11 Failure (8255).
-Control Panel key pressed while turning
power on.
-Shorted Control Panel key.
-Faulty ribbon cable or connector.
-A2Q4, Q5 or Q6 shorted.
-A2U2 (8279) or A2U4 (NE5090) Failure.
