Fault # 029
Pressure is not calibrated
Occurs when: Calibration pressure parameters are stored in two
addresses within chip U17 on the CPU board. During power-up
testing these two parameters are compared. Before an injection is
enabled, the software performs a limit check on the stored calibra-
tion pressure parameters. İf the parameters do not match, the Fault
message will be displayed.
Corrective action: Re-calibrate the Powerhead pressure. If the
error persists, replace chip U17 on the CPU board.
Fault # 030
Illegal state transition
Occurs when: The software has inadvertently moved into an erro-
neous siate.
Corrective action: Cycle power to correct problem. If this problem
persists, replace chips U10, U12, and U15 (RAM and ROM) on the
CPU board.
Fault # 031
Bad power head communications
Occurs when: The power pack detects a number of invalid commu-
nications packets from the powerhead.
Corrective action:
Replace U13 on the Mother board and/or U3 on
the Powerhead board.
Fault # 032
No power head detected
Occurs when: During Power-up tests, the CPU checks for signals
from the powerhead. If signals are not found, the Fault message
will be displayed.
Corrective action: Check the powerhead cable to ensure it is
securely connected to the connectors in the rear of the powerhead
and the rear of the electronics cabinet . If the Fault message contin-
ues, replace chips U13 and U14 of the Mother board and U1 of the
Powerhead board.
