Fault Description

Possible Causes

 

 

 

 

 

 

0041

State Invalid

S

The state machine implemented

Internal RAM error

 

 

 

within the CCU2 system software

CPU error

 

 

 

governs the operation of the PV225S.

 

 

 

 

 

This fault indicates that the PV225S

 

 

 

 

 

has detected an unknown system

 

 

 

 

 

variable and has encountered an

 

 

 

 

 

invalid state.

 

 

 

 

 

 

 

 

0042

Serial EEPROM

S

This fault indicates that the PV225S

Internal ROM error

 

Write Error

 

has detected a serial EEPROM write

CPU error

 

 

 

error. The CCU2 controller board

 

 

 

 

 

performs a verification check of data

 

 

 

 

 

written to ROM compared to what is

 

 

 

 

 

read back.

 

 

 

 

 

 

 

 

0043

Serial EEPROM

S

This fault indicates that the PV225S

Internal ROM error

 

Timeout

 

has detected that when writing data to

CPU error

 

 

 

the serial EEPROM, a confirmation

 

 

 

 

 

timer of 300mS has expired.

 

 

 

 

 

 

 

 

0044

Bad NOVRAM

S

This fault indicates that the PV225S

Internal NOVRAM

 

Memory

 

has detected that one of the two non-

 

error

 

 

 

volatile memory banks on the CCU2

CPU error

 

 

 

controller board has failed. The

 

 

 

 

 

CCU2 performs a series of tests to

 

 

 

 

 

confirm the validity of the

 

 

 

 

 

NOVRAM, and one of the two banks

 

 

 

 

 

has produced errors.

 

 

 

 

 

 

 

0045

Interrupt 2 Timeout

S

This fault indicates that the PV225S

• Internal A to D

 

 

 

has detected that an interrupt 2

 

converter error

 

 

 

timeout has occurred. The CCU2

CPU error

 

 

 

controller board performs a

 

 

 

 

 

conversion validation of analog-to-

 

 

 

 

 

digital data within the A to D

 

 

 

 

 

converters. If validation of the

 

 

 

 

 

conversion is not performed within

 

 

 

 

 

500mS, an interrupt 2 timeout fault

 

 

 

 

 

will occur.

 

 

 

 

 

 

 

 

0047

Software Test

S

This fault indicates that the PV225S

 

 

 

 

 

has detected that a software test fault

 

 

 

 

 

has occurred. This is a simulated fault

 

 

 

 

 

used for debugging purposes.
