Debug Screen 0 – Hydraulic Flow

Note: This screen will be different if Online Clearance (OLC) or Diasafe is not installed.

ACID

The number of acid pump steps (per stroke) sent to the actuator board from the functional board.
The actuator board will step the acid pump motor this many steps away from the end of stroke
sensor. This value is determined by the currently selected concentrate and should make the acid
pump deliver APV.

AACID

The actual number of acid pump steps sent to the acid pump by the actuator board. The actuator
board will step the acid pump motor until the end of stroke is sensed. AACI is the number of steps
counted until this end of stroke. If AACI does not equal ACID, an EOS error will be generated.

board. The actuator board will step the acid pump motor this many steps away from the end of
stroke sensor. This value is determined by the currently selected concentrate and should make the

LINOFF

Lines off. This pin = 1 if both the red and the blue dialysate connectors are out of the shunt. Both
dialysate lines must be in the shunt (LINOFF = 0) to start the cleaning modes.

sensor board, is fully on. This pin should be = 1 since there is no voltage available to the triac. If
the pin goes low (TRIAC = 0) during this time a “HEATER RELAY TEST FAIL” will be issued by the

needle operation, when the arterial blood pump runs, the venous blood pump does not and vise
versa. This pin monitors the blood pump during so that the functional board can control the venous
clamp. When the arterial blood pump runs, in single needle operation, the venous clamp is closed.

Access Flow Calculation Errors (three total) ;

Note Decn is the Kecn1 recalculated at the same Qb and Qd as the second OLC test for AF.

0 - No error
1 - Kecn1 = 0
2 - Qd = 0
3 - Qb = 0
4 - Special case that would cause an illegal divide by zero:

0.85*Qb = Qd

5 - Special case that would cause an illegal divide by zero:

0.85*Qb = Kecn

6 - Special case that would cause an illegal divide by zero:

(exp[(1 – Qb/Qd)* KoA/Qb] – Qb/Qd) = 0
7 - Decn1 = 0
8 - Special case that would cause an illegal divide by zero:

Decn1 = Kecn2

Decn1 & Decn2

The first OLC test is recalculated at the same Qb & Qd as the second OLC test for Access Flow.

Qd

Current dialysate flow rate, ml/min.

Time to Adj.

The time (min:sec) until the next time a new Cal-DAC value will be calculated.

T.Stability

The temperature stability value:

• Note: T is the average temperature sample over 2 seconds

• X180 = ((Avg (T1 to T180)) - (Avg (T121 to T180)) )2

• Tiinst180 = 110 – X180 (Limit to 0 - 100)

• Tiavg210 = Avg (Tiinst 181 to Tiinst210)

T.Set DAC

The temperature set DAC value:

C.DAC/C

The calibration DAC change necessary to get a 1°C change in monitor temperature at
Qd 500:

Avg.Mon.T

This is the average monitor temperature (6 min avg.)

Curr.Cal DAC

The is the Cal DAC being used by the machine (same as the table value for the current
Qd).

No Chg.Reason

The reason that the Cal-DAC was not adjusted at the last opportunity.

0- Monitor temp at 37, no change necessary or adjusted at the last opportunity.
Message: Not necessary

1- Not yet time for first adjustment after startup.
Message: Too early

2- Temp Stability not > 70.
Message: Temp Stability < 70

3- Dialysate flow rate change delayed adjustment.
Message: Qd adjusted

4- Fill Program delayed adjustment.
Message: Fill program

5- Heater off condition delayed adjustment.
Message: Heater off condition

6- Cal-DAC is at lower limit of allowed adjustment.
Message: Cal-DAC at low limit

7- Cal-DAC is at upper limit of allowed adjustment.
Message: Cal-DAC at high limit

DiaSafe

The setting for the DiaSafe option.

Cal Pre-Post Delta

The difference between the Pre and Post temperature sensors at 500 ml/min when the machine is
in bypass (during a calibration step).

Target DPC

This is the target DAC counts per degree C. This is shown only during the test.

Calc DPC

This is the calculated DAC counts per degree C determined by the test.

T Pre

Curr. = The current NTC3 (pre) or NTC4 (post) reading (2 sec avg.)
Avg. = The current NTC3 (pre) or NTC4 (post) average reading (6 min. avg.)
Mon. = The current monitor reading (NTC3 + monitor offset)

T Post

Curr. = The current NTC3 (pre) or NTC4 (post) reading (2 sec avg.)
Avg. = The current NTC3 (pre) or NTC4 (post) average reading (6 min. avg.)
