Rinse or Heat Disinfect: See procedure number
Dialysis: See procedure number
VE- 2.0.2 CHECK VALVE ERROR IN RINSE
a) Place the machine into Rinse Program and allow four minutes.
b) Call debug screen 1. Is VERR greater than 5?
Yes Assuming that all above procedures were performed correctly, three possibilities: 1) Bad
actuator board; 2) Bad actuator cable; 3) Bad distribution board. To isolate between the
three see procedure number
No Reseating the connectors may have remedied the Valve Error.
VE- 2.0.3 CHECK VALVE ERROR IN RINSE
a) Place the machine into Dialysis Program (remember to press the 'CONFIRM' key).
b) IMPORTANT! Allow 30 seconds then call debug screen 1. Is VERR greater than 5?
Yes Assuming all above procedures were performed correctly, three possibilities: 1) Bad
actuator board; 2) Bad actuator cable; 3) Bad distribution board. To isolate between the
three see procedure number
No Reseating valve connectors may have remedied the Valve Error.
VE- 3.0.0 TROUBLESHOOTING VALVE ERRORS
These procedures check solenoid resistance ( ) from the actuator board, through the actuator cable,
distribution board, and the valve's blue wiring harness:
Check ALL NOTED valves
CAREFULLY read the meter's numeric AND units display (M
ohms; K = Thousand ohms; "OL" = resistance too big to read)
IMPORTANT!
a) Turn the machine off!
b) Open the card cage and place a meter lead at chassis ground (see
c) Referring to Figure 41
(rear) side is arranged in two rows. Odd numbered pins (1, 3, etc) in the bottom row; even numbered
(2, 4, etc) in the top. As instructed
There is NO NEED to check all pins! ONLY the NOTED valves per
