Note
Lack of all voltage readings
is indicative of
blown low voltage power
supply fuse. Replace fuse
if necessary. Lack of a
single voltage level is
probably caused by a bad
connection or defective
power supply. If initialization

in arm power port
b Check that system is
initialized. Initialize
if necessary
c Check arm cable connections
Reconnect if necessary
d Check that clock terminator
board is firmly seated in
backplane and that board
connectors are installed
firmly. Reset as necessary
e Check that jumpers E1 to E2
and E5 to E6 are installed
on clock terminator board
Jumper as necessary
f Replace defective board
g. Disconnect all I/O modules
and attempt top turn on ARM POWER.
If ARM POWER comes on,
turn it off, replace
one I/O module, and attempt
to turn on ARM POWER again
Continue this procedure until
ARM POWER fails to
come on. Replace defective
I/O module
h Remove arm cable. Check
for continuity on all
lines. Replace arm cable
if continuity breaks are found
i Check board installation
per paragraph 5-4-1
correct installation as
necessary
j Replace defective board
k Replace defective board
l Replace defective board
m Replace defective board
n Check following on EPROM
board
1 All four jumper
inserted at top of
board (W1 to W4)
2 Sixteen pin dip socket
jumpered at positions
1,4,6, and 7
3 A and B EPROMS are
firmly seated, no
chips are missing,
and no pins are bent
or broken
o Check connector P23 at
CRT/TTY for the following voltage levels
1 Pins 3 & 4 = +12vdc
2 Pins 1 & 5 = -12 vdc
3 Pins 4 & 5 = +5 vdc
NOTE
Lake of voltage readings
are indicative of a blown
low voltage power supply
fuse. Replace fuse if necessary
p Try to turn on ARM POWER
Check voltage at lug 3 of the
solid state relay K1. The presence
of +3V or more indicates all
PC boards and high power
function board are good
K1 is faulty if ARM POWER
light is not on
Transformer T1 or Diode
Bridge BD1 is faulty if
ARM POWER light is on
Replace with know good
parts id necessary
NOTE
If arm power problem persists,

a. Check CRT and TEACH PENDANT
displays for error messages.
Refer to Table 5-1 for service
procedures in this table and the
User's Guide to VAL.
b Check CRT terminal switch
settings for adherence to
following:

supply fuse. Replace fuse
if necessary. Lack of a
single voltage level is
probably caused by a bad
connection or defective
power supply. If initialization
message problem persists, call

3 A and b EPROMS are
firmly seated, no
chips are missing,
and no pins are bent
or broken
l Diconnect all I/O modules
