VE- 7.0.0 ISOLATE VERR
a) From debug screen 0, RECORD the valve numbers of the valves whose ‘dots’ are BLUE!
One of
these valve circuits may be the problem!
These procedures isolate between them.
b) Call debug screen 1. NOTE VERR’s value for reference later. If VERR EVER reaches 255 return to
procedure number VE- 1.0.0 (
page 196
) to reset it.
c) Watch VERR until if it increases above what was noted in part b OR for five (5) minutes whichever
comes first! TWO (2) possible scenarios:
1)
IF VERR
DOES NOT
increase above what was noted in part b: A valve error is not
occurring at this time! Turn Dialysate Flow on. If a Flow Error reoccurs proceed to
page 30,
procedure number F- 2.0.0 .
2)
IF VERR increases above what was noted in part b: See procedure number VE- 7.0.1 (page
205).
VE- 7.0.1 ISOLATE VERR
a) At the distribution board (Figure below), unplug one of the RECORDED valves. This isolates the valves
solenoid and its wire harness.
Figure 40 – Distribution Board
b) Watch VERR until if it increases above what was noted in procedure number VE- 7.0.0, part b OR for
five (5) minutes whichever comes first! TWO (2) possible scenarios:
1)
IF VERR does DOES NOT increase: The last valve unplugged OR its blue wire harness is the
problem!
2)
IF VERR increases: Repeat procedure number VE- 7.0.1 until all RECORDED valves have been
unplugged. If after all these valve(s) are unplugged AND if VERR is still increasing, THREE (3)
possible bad components, see the Component List below:
Component List
Swap in each, one at a time, returning to Dialysis Program in between, until VERR remains = 0 for
10 minutes! 1) Actuator-Test Board; 2) Actuator Cable; 3) Distribution board
