Table 4.12 Fault Codes
Err
Code
Description Possible Cause Things to check Correction
100 Test or CAL mode
dip switch with no
remote power con-
trol key press
The Remote Power Control
Key must be depressed
when power initialized
until the test tones sound.
Release this key before the
last tone sounds.
Cycle system power while press-
ing the Remote Power Control
Key and determine if this error is
repeated.
Replace the
Controller assembly.
101 Controller/Monitor
DIP switch mis-
match
The System Controller and
the Monitor do not detect
the same settings for the
Configuration Dipswitches.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
102 Corrupted com-
munications
between the System
Controller and
Monitor
The data transmitted from
the System Controller to the
Monitor through the HPI
port is faulty.
This could be caused by
damage to components
associated with the HPI bus
on the Controller, permit-
ting electromagnetic inter-
ference to upset one of the
processors.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
103 Corrupted com-
munications
between the System
Controller and RF
Controller
The data transmitted from
the System Controller to the
RF Controller through the
HPI port is faulty.
This could be caused by
damage to components
associated with the HPI bus
on the Controller, permit-
ting electromagnetic inter-
ference to upset one of the
processors.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
104 Monitor TOKEN
not incremented,
monitor program
scrambled
The data transmitted from
the System Controller to the
Monitor through the HPI
port is faulty.
This could be caused by
damage to components
associated with the HPI bus
on the Controller, permit-
ting electromagnetic inter-
ference to upset one of the
processors.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
105 Controller failed
ram test
The System Controller
memory errors have been
detected during POST.
Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
