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
message problem persists, call 
RP Automation Field Service

processor board

l Defective CMOS
board

m Blown AC fuse in 
low voltage power supply











n Defective 
solid state relay
a. Verify external interlocks 
or install auto start plug
in arm power port

b Check that system is 
initialized.  Initialize 
if necessary

c Check arm cable connections
Reconnect if necessary

d Check that "B" interface 
board is firmly seated in 
backplane and that board 
connectors are installed 
firmly.  Reset as necessary
Replace defective "B" interface 
board

e Replace Defective "B"
interface board


f. 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

g Remove arm cable.  Check
 for continuity on all 
lines.  Replace arm cable 
if continuity breaks are found



h Check board installation
(refer to label inside top
cover of controller)

i Replace defective "A" interface
board; then replace defective 
"B" interface board if problem 
is not resolved


j Replace defective board


k Replace defective board


l Replace defective board


m 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

n Try to turn on ARM POWER
Check voltage at lug 3 of K1

+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 if necessary

NOTE

If arm power problem persists,
cal RP Automation

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:

(1) Hazeltine 1410: DIP switches 
1  & 2 ON, remainder OFF.

(2) ADDS Regency 20: DIP switch 
5 ON, remainder OFF.

(3) UNIMATION Industrial CRT: 
Test Mode switch at NORMAL. 
Jumpers in 9600 Baud position 
(marked 960).

NOTE

For any terminal being used, 
ensure that FULLDUPLEX mode has 
been enabled.

c. Check terminal connections at 
back of terminal and at back of 
controller for tightness. 
Tighten as necessary.

d Check terminal cable wirinq 
for continuity. If any wire 
lacks continuity, replace 
terminal cable.

e Check cable jumpering for
adherence to the following:

1 CRT cable jumpered
from pin 2 to pin 9
for baud rate of 9600

2 TTY cable jumpered 
from pin 2 to pin 10
for baud rate of 300

f check seating of quad serial
board (DLV11-J), and 
check jumpering for
adherence to the following:

1 0-2-N lines jumpered
for baud rate of 9600

2 1-Y lines jumpered for
baud rate of 2400

3 3-T lines not 
jumpered

g Check seating of LSI-11/73
or LSI-11/23microprocessor 
board 

h 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
Lack of all voltage readings
is indicative of a
blown low voltage power 
supply fuse.  Replace fuse
if necessary.  

i Check seating of "A" interface 
board

j Checking seating of CMOS
board



k Disconnect all I/O modules 
and attempt to use the 
terminal.  If terminal 
communications are correct,
shut system down and 
reconnect on I/O module.
Continue this procedure
until the original proplem 
reappears.  Replace defective
I/O module

NOTE
If terminal response 
problem presists, call
RP Automation Service 
Department 

 
Garbled 
initialization 
message (ter-
minal powers up; 
controller 
powers up).
 
a. Loose terminal 
connections.




b. Board(s) not 
securely seated.


c. Defective boards).
 
a. Check terminal connections 
at back of terminal and at 
back of controller for 
tightness. Tighten as 
necessary.

b. Check boards in card cage 
for proper seating.


c. Replace boards in the fol-
lowing sequence, checking if 
problem persists after each 
replacement.

(1) Quad serial board
(2) "A" interface board
(3) LSI-ll microprocessor
(4) "B" interface board
(5) CMOS board
