Yes The actuator board is okay. Replace valve #43.
No NOTE that VALVE #43 (ONLY) will be checked and proceed to page 78,
TROUBLESHOOTING
FIL- 3.0.7 CHECK FOR AIR
a) CAREFULLY return the female connectors to their
probes on top of chamber #39. Brown wire on top!
IMPORTANT!
b) Place BOTH dialyzer connectors
into the shunt!
c) With the shunt door open and referring to the
Figure (right), check the external dialysate line filter
#73 (if present) for restrictions.
d) Close the shunt door.
IMPORTANT!
e) ASSURING Dialysate flow is ON
(Dialysate Flow on/off LED off), allow one minute.
f) From debug screen 1, watch FILACT for one minute. Proceed accordingly:
FILACT = 1 (constant): See procedure number FIL- 3.0.8 (page 173).
FILACT = 1 (intermittent): See procedure number
FILACT = 0 (constant): Reseating the connectors may have remedied the problem. Do NOT
continue.
FIL- 3.0.8 CHECK FILLING PROGRAM
a) Turn the machine off for two minutes then turn it back on.
b) Place the machine into Dialysis program (remember to press the 'CONFIRM' key).
c) Allow eight minutes for Temperature and Conductivity to stabilize.
d) From debug screen 1, does FILACT remain = 1 constant?
Yes See procedure number
No Do NOT continue!
FIL- 3.2.0 CHECK AIR SENSOR CIRCUIT
a) Referring to the Figure (right), CAREFULLY place one of the resistor
plugs, from the four-resistor Temperature set, into distribution board
position labeled "AIR-SEN". This simulates 'no air in chamber #69'.
IMPORTANT!
b) Allow 30 seconds. FILACT response is not
instantaneous! From debug screen 1, is FILACT = 0 constant?
Yes The female X6 connector is bad (see
171).
No a) ASSURE the resistor plug is placed correctly (at distribution board "AIR-SEN") before
continuing! If not, repeat procedure number
b) See procedure number
