CT 9000? ADV
Fault # 015
PWM stop would not turn on
Occurs when:
During Power-up testing, the PWM STP STATUS
line, U5 pin 3, is checked to ensure that the DEAD STOP line, U6
pin 1, can turn the PWM stop on by itself. The failsafe is toggled
which causes U5 pin 1 to be high. U6 pin 1 is toggled low, causing
U5 pin 2 to be low. If the output of U5 pin 3 is low, the CPU will
display the Fault message at the end of Power-up testing.
Corrective action:
Check U5, U6 U14, and U16 on the Mother
board.
Fault # 016
Position is not calibrated
Occurs when: Calibration position parameters are stored in two
addresses within chip U17 on the CPU board. During power-up
testing and before an Injection is enabled, these two parameters
are compared. If the parameters do not match, the Fault message
will be displayed.
Corrective action: Re-calibrate the Powerhead position. If the error
persists, replace chip U17 on the CPU board.
Fault # 017
Lost power head communications
Occurs when:
During operation of the CT 9000, the CPU continu-
ally checks for signals from the powerhead. If a 3 second lapse
occurs between receiving signals from the powerhead, 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 on the Mother board and U1 on
the Powerhead board.
Fault # 018
Lost console communications
Occurs when: This Fault message is only visible when two con-
soles are active. If this problem occurs while using a one-console
system, the Fault Indicator light (the Injecting light) on the
Powerhead will flash and the console keyboard will be locked-up.
Corrective action: Check the console cable to ensure it is securely
connected to the connectors in the rear of the console and the rear
of the electronics cabinet. If the console does not respond to these
actions, replace the Console board.
