|
a Check terminal connections
at back of terminal and at back of
controller for tightness.
Tighten as necessary
b Begin startup sequence
again . Terminal must be on
with a visible cursor before
turning controller power on
c Check boards in card cage
for proper seating
d Check connector J76
VIDEO for the following
voltage levels:
1 Pins G & J = +12vdc
2 Pins G & C = -12 vdc
3 Pins G & K = +5 vdc
e Replace defective board
f Replace defective board
g Replace defective board
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

f E-Stop pushed in
g Fault light on
h Boards installed
improperly
i Defective Arm Signal
interface board or
Arm interface board
j Defective I/O
module
|
a. Verify external interlocks
or install CX jumper plug
in J145
b Check that a teach
pendant is installed or
teach pendant jumper
installed
c Answer yes or no to
initialize question
d Check continuity of arm
cable and retry to start
system again
e Ensure that remote
interlock are correct
or place remote local
switch into local mode
f. Ensure all e-stops are
set and controler e-stop
is out
g Ensure the fault light is
out if not look in controller
for red error leds
h Check board installation
and ribbon cable. Then try
to restart system
i Replace defective Arm Signal
interface board; then replace
defective Arm interface board
if problem is not resolved
j 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

seated
k Defective I/O
module
|
a. Check CRT and TEACH PENDANT
displays for error messages.
Refer to Chapter 5 for service
procedures in the
Unival Equipment Manual
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 set for baud rate
of 9600
f check seating of ribbon
cables on distribution board
Then restart system
g Check seating of SCM CPU
board
h Check connector J76 at
terminal port for the
following voltage levels:
1 Pins G & J = +12vdc
2 Pins G & C = -12 vdc
3 Pins G & K = +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 TP
board
j Checking seating of extended
memory 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
