T- 1.1.0 CHECK TEMPERATURE ALARM
Referring to the Figure right, with Temperature between 35.1 and
38.9° C, is the Temperature window RED?
Yes a) ASSURE Temperature is set to 37° C per procedure number
b) If the Temperature window remains RED, three possibilities: 1) Bad actuator board;
2) Bad sensor board; 3) Bad function board.
No See procedure number
T- 1.1.1 CHECK CONDUCTIVITY ALARM
From the Home screen, is the Conductivity window RED?
Yes a) Per procedure number
274
resistor plug is placed correctly at distribution
board position labeled "COND"!
b) If the Conductivity window remains RED, see procedure number
No See procedure number
T- 1.1.2 CHECK FOR CONDUCTIVITY ALARM
a) Select the 'Dialysate' tab at the bottom of the screen to call the 'CONFIRM
Concentrate screen.
b) Using the screen's 'Alarm Position' and/or the 'Alarm Width' buttons are you
able to adjust the Alarm Limits until 'actual' conductivity is BETWEEN the
upper and lower alarm limits (see Figure right)?
IMPORTANT!
Yes
number T- 1.1.3
No See procedure number
T- 1.1.3 CHECK 'OUT OF BYPASS' FUNCTION
IMPORTANT!
a) ASSURE the shunt door is closed!
b) Is the Bypass LED (front panel) OFF constant?
Yes See procedure number
No Repeat from procedure number
here, and all above procedures have been performed correctly, three possibilities: 1) Bad
actuator board; 2) Bad sensor board; 3) Bad function board.
T- 1.1.4 CHECK 'OUT OF BYPASS' FLOW
a) From the Home screen set Dialysate flow to 500 ml/min (NOT "a500").
IMPORTANT!
b) Do NOT reset alarms!
c) Is the external flow indicator's (#75) 'bob' rising (at least ¼ way up) and falling (see
Figure right)?
Yes See procedure number
No a) CAREFULLY return Conductivity cell #7 and NTC #3 to their distribution
board positions (respectively labeled "COND" and "MON-NTC").
b) Proceed to page 14,
T- 1.1.1 (page 97).
T- 1.0.9 (page 96) ASSURE the
T- 1.1.3 (page 97).
Press the 'CONFIRM' key then see procedure
(page 97).
