Tsv- 2.0.0 Isolate Valve Wires; Tsv- 2.1.0 Isolate Valve Solenoid; Tsv- 3.0.0 Check Solenoid - Fresenius Medical Care 2008K2 Troubleshooting Manual

TSV- 2.0.0 ISOLATE VALVE WIRES

a) THREE (3) checks, WHILE tracing the NOTED valve's wires from
the distribution board to the solenoid terminals (Figure right):
Check #1: ENSURE no pinched or bare wires!
Check #2: ENSURE both wires terminate PROPERLY at the
valve's solenoid terminals!
Check #3: ENSURE no corrosion at the solenoid terminals!
b) If no problems were located, see procedure number

TSV- 2.1.0 ISOLATE VALVE SOLENOID

a) Figure right, open the cap from the NOTED valve's
distribution board connector.
Except for Valve #26
b)
connected between the top and bottom terminals.
Valve #26 (ONLY!) MUST BE connected between the
second from top and bottom terminals! If wired
incorrectly this is the problem!
Set your CALIBRATED volt meter to RESISTANCE (Ω)!
c)
d) Where the wires are connected, place one meter lead on one terminal and the other lead on the other.
e) Figure right, reading the meter's numeric AND
UNITS (Ω), between 40 and 100
Between 40 and 100 Ω! FIVE (5) possible bad components (see Component List below).
Yes
Swap in one at a time and in between test the machine.
Component List: 1) The NOTED valve; 2) Actuator-Test Board; 3) Actuator cable;
4) Functional Board*; 5) Distribution board
* To prevent "Cond Offset Failure" place the machine into T and C (refer to
OPERATING MODES
Less than 40 Ω OR more than 100 Ω! See procedure number
No

TSV- 3.0.0 CHECK SOLENOID

Figure right, place one meter lead on one solenoid terminal and the other lead
on the other terminal. Between 40 and 100 Ώ?
Between 40 and 100 Ω! The valve's wiring harness is bad.
Yes
Less than 40 Ω OR more than 100 Ω! The valve's solenoid is bad.
No
