Table 6-0: Main CPU Faults
Faults
Description
Possible Cause/Suggested Fix
IHS I/O
Failed Off
Inspection High Speed
I/O Failed Off. This
input is used with an
electronic Bucher
valve. The IHS input
or output failed off.
• Faulty IHS input. Replace or relocate the input board.
• Faulty IHS output. Replace or relocate the output.
IHS I/O
Failed On
Inspection High Speed
I/O Failed On. This
input is used with an
electronic Bucher
valve. The IHS input
or output failed on.
• Faulty IHS input. Replace or relocate the input.
• Faulty IHS output. Replace or relocate the output.
Inspection Input Flt
More than one input
is on in the inspection
string. The inspection
string condition is also
shown on the safety
processor.
• Faulty Top of Car inspection wiring. Verify voltage on CTA
and ICA terminals when car top inspection switch is in the
run position. Verify INS input when switch in the inspection
position.
• Verify that one and only one in
spection string inputs is on:
AUTO, MRI, INS, ICI and ACC.
• Faulty inspection string input: AUTO, MRI, INS, ICI or ACC.
Replace faulty input chip
Inspection Up/Dn Sw
An up or down
inspection run input
was on when first
entering into
inspection operation.
This caused from a
faulty inspection up or
down switch or from
someone holding the
up or down run
button when placing
the car on inspection.
• Faulty inspection up or down input: IU, ID, MRIU, MRIU,
BAD, BAU, TAD or TAU. Replace faulty input chip.
• Faulty inspection wiring keeping an inspection up or down
input on.
• Placing the car on inspection while holding an up or down
run button
Invald DT or DT1 Cnt
Invalid DT or DT1
Count. The position
count for DT is greater
than the count for DT1
•
Invalid hoistway learn or the hoistway learn is not
complete. Re-learn the hoistway or complete the hoistway
learn.
• The bottom terminal floor limits are calculated and
stored when the bottom floor is learned. Bring the car to the
bottom floor and re-learn the floor position.
• If this problem
is not corrected with a hoistway learn, contact the factory
