F- 13.0.0 ‘BOB’ IS MOVING WHEN IT’S NOT SUPPOSED TO
The Temperature AND / OR the Conductivity window is REMAINING RED BUT the external flow
indicator’s bob is moving!
a) Per the Figure BELOW, trace the wires from Valve #24’s AND #26’s distribution board connectors, to
Valve #24 and #26 in the hydraulics to ENSURE they are wired to the CORRECT valve!
b) Figure left, open the plastic female cover from
Valve #26’s distribution board connector.
c) Valve #26 wires MUST be soldered between pins two
(second from the top) AND five (bottom). If between the
top and bottom pins Valve #26 is probably connected to
distribution board position “V24” and vice versa!
d) Return Valve #26’s connector to distribution board
position “V26”.
e) ENSURING [Dialysate Flow] is set to 800 ml/min AND is not blinking is the external flow indicator’s
‘bob’ still rising?
Yes ‘Bob’ moving! TWO (2) possible bad components: 1) Actuator-Test Board OR; 2) Valve
#24.
No ‘Bob’ NOT moving! If a Flow Error is still occurring, return to (ABOVE) procedure number
F- 6.0.0 (page 58). If the Flow Error never occurs do not continue.
