f) From debug screen 1, does FILACT = 0 constant?
Yes See procedure number
No After 30 seconds, If FILACT still = 1, see procedure number
FIL- 3.0.4 CHECK FOR MASKED FLOW ERROR
Filling Programs can mask Flow Errors. This procedure assures that a Flow Error is not present when
FILACT = 0.
a) Re-check loading pressure. If (and ONLY if) it is NOT peaking to between: 23 and 27 psi (equipped with
®
DiaSafe filter); 17 and 23 psi (NOT equipped with DiaSafe
number F- 2.0.4.
b) Call debug screen 0 and CAREFULLY watch Flow Error for two minutes or until if Flow Error = 1.
Proceed accordingly:
Flow Error = 0 (constant): See procedure number
Flow Error = 1 (constant or intermittent): Proceed to page 14,
DIALYSIS PROGRAM.
FIL- 3.0.5 CHECK VALVE #43 FLOW TO DRAIN
In Filling Program all flow goes through valve #43. This procedure checks if valve #43 is opening properly.
A 1000 ml graduated cylinder is required:
a) Disconnect the female connectors from each other but
chamber #69 yet! SEPERATE them so that they do NOT contact each other! This simulates 'air in
chamber #69.
b) Allow 30 seconds. From debug screen 1, ASSURE FILACT = 1 (Filling Program active) constant.
c) Referring to the Figure (right), at the far end of the
drain tubing, if a 'Quick Connector' is present, an
adaptor IS required to allow flow.
IMPORTANT!
d) Assure Dialysate Flow is ON
(Dialysate Flow on/off LED off).
IMPORTANT!
e) Do NOT reset alarms!
f) Allow 30 seconds
g) ACCURATELY measure drain flow for 30 seconds into a 1000 ml graduated cylinder. Two
measurements are recommended especially if the first is low. 250 ml or greater?
Yes See procedure number
No a) If Dialysate flow is NOT on (Dialysate Flow on/off LED off) repeat
from part d.
b) See procedure number
FIL- 3.0.6 ISOLATE VALVE #43 / ACTUATOR BOARD
IMPORTANT!
a) Place BOTH dialyzer connectors into the shunt and close the door.
b) From debug screen 1, ASSURE FILACT remains = 1.
c) Allow four minutes to allow valve #43's solenoid to become warm (if energized).
d) Referring to Figure 66
(i.e. energized)?
FIL- 3.0.4 (page 172).
FIL- 3.0.7
FIL- 3.0.6
(page 171), and after four minutes, touch valve 43's (black) solenoid. Is it warm
