TROUBLESHOOTING VALVE ERRORS IN DIALYSIS PROGRAM
If VERR = one (1) or more and / or is continuing to increase indicates a valve circuit resistance of less than
20 Ω and is used for troubleshooting. HOWEVER, if VERR reaches it maximum of 255 it becomes useless!
A) From here forward, Figure right, if (and ONLY if) a “Dial
Valve Failure” OR “Act Byp Valve Fail” banner EVER
appear proceed to page 711, Section 26
B) For now, ignore a “V104/108 Stuck Closed” or “V105 Stuck Closed” alarm if one occurs!
C)
CLOSE the SHUNT door!
D) ENSURE a “No Water” alarm NEVER appears!
E) FIGURE BELOW, a previous procedure may have already placed a resistor plug in the distribution
board’s AIR SENSOR position

th
connector cap i.e. 5
th
position FROM THE LEFT!
F) TWO (2) possible scenarios below:
1) IF (and ONLY if) a resistor plug is ALREADY in place: See procedure number
VE- 1.0.0
(page 214).
2) IF a resistor plug IS NOT in place: See parts a THROUGH e next page:
