T- 7.0.3 TROUBLESHOOT 'NO FLOW' THROUGH FLOW INDICATOR
a) Activate the [TEMP DAC] data box (it turns bright yellow) and set its value to "20". This should turn
2
the heater off. K machines ONLY pressing the 'CONFIRM' key twice activates [TEMP DAC].
b) Press the 'CONFIRM' key (the data box turns pale yellow). IMPORTANT NOTE! If the data box
turns gray the 'CONFIRM' key was accidently pressed twice. In this event, press the
'Escape' key then return to Calibrate Sensors
procedure number
c) Allow twelve minutes. Does the [Monitor Reference] data box decrease to and remain 38° C or
lower?
Yes See procedure number
No See procedure number
T- 7.0.4 CHECK DIALYSIS PROGRAM ALARMS / ADJUST TEMP DAC AND MONITOR REFERENCE
a) Turn the machine off, back on and return to Dialysis Program (remember to press the 'CONFIRM' key).
b) If (and ONLY if) a "No Water" message appears on the screen, proceed to page 64,
WATER.
c) Call debug screen 0 and watch Flow Error for two minutes If (and ONLY if) Flow Error = 1 (constant or
intermittent) proceed to page 14,
d) Place the machine into Service Mode
e) Activate the [TEMP DAC] data box (it turns bright yellow) and decrease it by 40. Example: if [TEMP
DAC] = 145 set it to 105. K
f) Press the 'CONFIRM' key twice to activate the screen's [Monitor Reference] data box (it turns bright
yellow).
g) Set [Monitor Reference] as low as it will go then press the 'CONFIRM' key twice to save the calibration.
h) Return to procedure number
T- 7.0.5 CHECK TEMPERATURE INCREASE
a) During these remaining procedures, keep a watchful eye on the external flow indicator. If (and ONLY if)
the 'bob' EVER STOPS moving up for longer than 5 seconds press the 'Escape' key then return to
procedure number T- 7.0.2
b) From the external meter's reading, proceed accordingly (three scenarios):
1) Increases to (but does not remain) 41° C or greater: Return to Dialysis program (remember to
press the 'CONFIRM' key) then see procedure number
2) Remains less than 35° C: See procedure number
3) Remains greater than 35° C but NEVER exceeds 41° C: See procedure number
124).
T- 7.0.6 CHECK HEATER VOLTAGE
a) Unplug the connector from the
position from the left (labeled "CON-NTC"). This is NTC #2.
b) CAUTION! 120 Volts AC possible! Referring to the Figure
(right), measure AC voltage (
heater connector, between the: Old style heaters: BROWN
and BLUE wires; New style heaters: BLACK and WHITE
wires.
