2) IF any “24V” alarm OR “Loading Software….Please Wait” lasts longer than one (1) minute:
Proceed to
page 625
, procedure number
3) IF a “24V” alarm has never occurred but “Failed Sending Data To Actuator Board” has:
If the
“Actuator Board” alarm reoccurs one of the card cage boards may be interfering with communication
between the Actuator-Test Board and the Functional Board. The most likely culprit is the Actuator-
Test Board itself.
4) ALL other scenarios:
(page 624).
P- H.4.1 ISOLATE “5V High” OR “5V Low OR “12V Power Fail”
The following procedure describes how to use the debug screens to m5 and +12 volts:
a) Select the screen’s ‘Dialysis’ button but
DO NOT
press CONFIRM yet!
b) Call debug screen 1 and locate
5V Est
AND
12V Est
(Figure right):
•
5V Est:
If EVER less than 4.8 (“5V Low”) OR more than 5.3 (“5V High”) OR
unstable (changes more than +/- 0.1) see procedure number
(page 624).
•
12V Est:
If EVER less than 11.7 OR more than 12.3 (“12V Power Fail”) OR unstable (changes
more than +/- 0.1) see procedure number
(page 624).
c) At the bottom of the screen, select the ‘Dialysate’ tab, THEN press ‘CONFIRM’ to return to Dialysis
Program!
d) Call debug screen 1.
e) WITHOUT LOOKING AWAY, watch
5V Est
AND/OR
12V Est
for ten (10) minutes or longer.
Does
5V
Est
OR
12V Est
become UNSTABLE (changes more than +/- 0.1)?
Yes
Unstable! See procedure number
(page 624).
No a) To generate cabinet temperature place the machine into Heat Disinfect then call debug
screen 1. If debug does not appear press ‘Escape’ then call screen 1.
b) If
5V Est
OR
12V Est
BECOME unstable see procedure number
(page 624).
If Heat Disinfect completes without a voltage-related alarm occurring the
Troubleshooting Guide cannot locate an immediate problem!
P- H.4.2 HEAT-RELATED FAILURE?
a) The most likely cause of this failure is the Power Logic Board (see Figure 4A and NOTE A (page 9)).
Replace it with a known good then see part b
(page 624) to watch
5V Est
AND/OR
12V Est.
. ALLOW
SUFFICIENT TIME! If the problem reoccurs next try a known good Sensor Board then see part c.
(page 624) to watch
5V Est
AND/OR
12V Est.
. ALLOW
SUFFICIENT TIME. If the problem reoccurs see procedure number
(
page 610
