PGC5000 Series Service Instructions 5 Diagnostics and troubleshooting
SI/PGC5000-EN, Rev B 20
If CR7 remains solid red and CR8 is OFF, an unexpected fatal condition occurred. CR1 (MSB) through CR6 form a binary code as
follows indicating the error:
000001 flash erase error
000010 flash write error
000011 powerfail interrupt
001000 no viable CANbus detected after 10 tries
001001 no auxiliary board detected
If CR7 and CR8 stay solid red (after the Digital Temperature Controller is operational) an unhandled interrupt has occurred. CR1
(MSB) through CR6 form a binary code indicating the error as follows:
000001 INT1.x
000010 INT2.x
000011 INT3.x
000100 INT4.x
000101 INT5.x
000110 INT6.x
000111 SCI-A RX
001000 SCI-A TX
001001 SCI-B RX
001010 SCI-B TX
001011 eCAN 0
001100 eCAN 1
001101 user trap
001110 PIE_RESERVED
001111 rsvd_ISR
010000 CPU timer 1
010001 CPU timer 2
010010 data logger
010011 RTOS
010100 emulation
010101 non-maskable
010110 illegal operation
Other LEDs also indicate various procedures, as noted on the previous figure, occurring via the board and are noted below:
CR10: Green. Blinking CANBus active.
CR12: Green, Blinking CANBus active.
CR13: Red, blinking Power to zone 2 heater.
CR14: Red, blinking Power being applied to zone 3 heater.
CR15: Red, blinking Power being applied to zone 4 heater.
CR16: Red, blinking Power being applied to zone 5 heater.
CR17: Red, blinking Power being applied to zone 1 heater.
CR18: Red PIC has enabled the main heater switch.
CR20: Green DSP power voltages good
Red DSP Power issue
5.3.5 Detector CANbus node identification
The Detector CANbus node identification is set at the factory by jumpers per ABB Bulletin 851J003. This bulletin is supplied
with all replacement detector amplifiers. The bulletin covers all jumper settings required for any detector amplifier. To ensure
correct jumper settings are applied to the new detector amplifier, take a picture of the original detector amplifier and reference
this picture when applying jumpers to the new board.
