T- 2.1.4 DIODE 17 CHECKED GOOD OR POWER CONTROL BOARD WAS REPLACED
a) IMPORTANT! Figure below, ENSURE all cables are PROPERLY connected to the Power Control
board!
NOTE! A good diode 17 does NOT necessarily mean the Power Control board is good
b) If troubleshooting a DIALYSIS PROGRAM temperature problem return to it (“Select Program” →
‘Dialysis’ → ‘Enter’). If a HEAT DISINFECT problem return to HEAT DISINFECT.
c)
Set to volt meter to AC voltage (~ V, V
AC
).
d) Figure right, measure BETWEEN the Heater
Connector’s BROWN and BLUE wires. TWO (2)
possible scenarios:
1) IF more than 100.0 volts AC! Return NTC #2’s
connector to the
1st distribution board position
from the left, “CON-NTC”. The new boards fixed
the problem!
2) IF less than 100.0 volts AC! See procedure
number T- 2.1.5 (page 288).
T- 2.1.5 HEATER VOLTAGE LESS THAN 10 VOLTS AC
a) Set your meter to DC voltage (V
DC
).
b) Connect the black lead to chassis ground.
c) Measure again at the Power Logic board’s
T5 TOP pin. If necessary, refer to Figure 44 (page 282).
d) LESS THAN two (2.0) volts DC?
Yes T5 LESS THAN 2.0 volts! Proceed to
page 291, procedure number T- 2.1.8.
No T5 between 2.0 and 28.0 volts! See procedure number T- 2.1.6 (page 289).
