FIL- 3.0.1 CHECK OLC SENSORS
a) Call debug screen 0. Referring the Figure (right), if (and ONLY if)
the Post Dialyzer Cond and Temp sensors do NOT appear skip to
FIL- 3.0.2 (page 171).
b) Are 'pre and post-dialyzer' Temp values within 1.2 of each other?
Yes See procedure number
No See procedure number
FIL- 3.0.2 CHECK OLC SENSOR CONNECTORS/ CABLES
Referring to Figure 65 (page 170), reversed connectors x13 (post dialyzer cond cell) and x44 (post dialyzer
temp sensor) will cause Filling Programs. CAREFULLY trace each cable from the distribution board to the
sensors inside the hydraulics. Check also for insulation damage! Are they reversed or damaged?
Yes Plug them in correctly (if reversed) or replace them (if the insulation is damaged) then see
procedure number
No See procedure number
FIL- 3.0.3 CHECK AIR SENSOR #6 ELECTRICAL CONNECTIONS
a) Referring to the Figure (right), assure the air sensor connector is
plugged into distribution board position labeled "AIR-SEN".
b) Referring to Figure 66
"AIR-SEN" terminates at the male probes on top of chamber #69.
The brown wire should be at the top!
c) From debug screen 1, continue ONLY if FILACT = 1. Reseating
connectors may have remedied the problem!
d) Referring to the Figure (right) and without pulling on the wires
remove both female connectors from the male probes and connect
them snug together. This simulates 'no air in chamber #69'. Leave
them connected together until instructed otherwise!
IMPORTANT!
e) Allow 30 seconds. FILACT response is NOT
instantaneous.
