c) ENSURE [
Temperature
] is still less than 35.0° C.
d) Figure right, measure BETWEEN the Heater
Connector’s BROWN and BLUE wires. TWO (2)
possible scenarios:
1)
IF MORE THAN 100.0 volts!
The heater is on! See
2) IF LESS than 100.0 volts AC!

page
T- 2.0.4 HEATER ON (MORE THAN 100 VOLTS)
a)
Return NTC #2’s connector to the 1
st
distribution board position from the left,
“CON-NTC”.
b) Call debug screen 0. Watch for six (6) minutes to ENSURE
Flow Error
is NEVER = 1 and a “No Water”
NEVER occurs.
c) From the Home or Heat Disinfect screen, [
Temperature
] should increase to:
•
IF in Dialysis Program:
Between 35.0 and 39.0° C.
•
IF in Heat Disinfect:
After no more than thirty (30) minutes, more than 80° C!
d) The low temperature problem may be intermittent and occurs ONLY after the machine has been running
for a while with good temperature. In this event
DO NOT
turn the machine off!
e) ENSURING a “No Water” alarm OR a Flow Error are NOT occurring AND there is less than 10 volts AC
at the heater, unplug NTC #2. If heater voltage returns to more than 100 volts AC replace NTC #2. If (and
ONLY if) heater voltage remains less than 10.0 volts AC, TWO DC voltage measurements isolates the
entire heater circuit:
Measurement #1:
(page 263) at x2,
pin 6
. Good = more than 9.6 volts DC.
Measurement #2:
Per
(page 264), at
T5’s TOP
pin. Good = less than 2.0 volts DC.
f) TWO (2) possible scenarios:
Scenario #1: IF (and ONLY if) BOTH measurements are GOOD:
All card cage signals are okay.
There is an intermittent problem with the Triac or the Power Control Board in the power
supply.
Scenario #2: IF a BAD signal is measured:
TWO (2) possibilities:
If
pin 6
is less than 9.6 volts DC
(page 274). If
T5
is more than 2.0 volts DC see procedure
