3. Introduction
The valve tester is designed to verify the correct operation of EGR valves and throttle
valves. Electrical drive units and units with position sensor(s) can be tested.
Its operation consists of making a series of activations on the valve motor and capturing
the response of the sensor (or sensors) to compare it with the expected signal. The
expected signal consists of a margin (tolerance).

7. How to use
1 – With the tester properly positioned, the power supply can be connected to a
suitable power outlet and to the tester device.
2 – Next, we can activate the switch on the rear side in the ON position.
3 – After viewing the startup progress bar, the screen will remain black for a few
seconds before displaying the screensaver.

4 – Click anywhere on the screen to exit the screensaver.
Note: The screen saver will automatically appear again if the machine is idle for more than
5 minutes.
5 – The first screen that we will see is the main menu. In this we can change the
language of the interface by pressing the corresponding flag in the upper right corner.
We select the type of device that we want to check (EGR or Throttle valve) using the
two buttons at the bottom.
6 – After selecting the type of device we will access the part number selection screen.
We slide the list until we see the desired part number and clickon it, or use the numeric
keypad to search for the desired part number manually.

Note: The part number is found on the product box label and engraved on some surface of
the valve to be tested. In this example image we have selected the part number AF07676 -
93023.
7– On the next screen we can see the selected part number as confirmation. In this
interface, the cable number to be used for this device is indicated. Connect the
corresponding cable to the tester.
Note : Each of the included cables has a colored label with the cable number. The circular
connector of the tester has a precise mounting position: rotate the connector on the base
until it clicks, and screw the clamp gently.

8–Place the valve to be tested in a
horizontal position on a soft surface
(cardboard, cork, expanded
polyethylene, etc.) and connect the
other end of the cable to it.
Note: It ' simportant to connect the
cable carefully and not to force the
connector at any time, so as not to bend
or damage the valve pins or the
connector terminals.
To initiate the test,press the button in the lower right corner.
Note: If we have selected an incorrect part number we can press the button in the
lower left corner to return to the previous selection view.
9 – Next, it can be observed 4 verification steps carried out by the tester.

Verification of the tester´s
electronic status.
Verification of the device
parameters recorded in the
database.
Verification of the system power
supplies (0V, 5V and 12V)
Verification of pin configuration,
detection of motor and sensors
If a fault is detected in any of the checks, the following alert will appear with the fault
number (in this example 27) and a brief description.
Note: See section 10 of this manual fordetailed information oneach fault.
10 – If all verifications are correct, the valve testing process is initiated.

In this phase, 4 activations will be carried out where the valve will move at
different speeds. Each activation lasts approximately ten seconds. Aprogress bar will
be visible for each of them with 4 states:
1. Green color: Activation has been completed successfully.
2. Red color: Activation is complete, but failures have been detected.
3. Gray color and moving: This activation is running.
Important note: During the activations, the valve´s operation will be audible, and it will
produce a vibration typical of the movement of the valve motor. These effects are
normal during the test. If the vibration of the valve produces a displacement of it on the
table, we must hold the soft surface on which we have placed the valve to
prevent it. Under no circumstances should we touch the valve when it is in
operation (it has moving parts and could cause crushing injuries).

11 – After the activations are completed, and after a few seconds of processing, the
graph viewer located onthe first ofthe four pages will be displayed.
At the top we can see valve information formed by EGR or THR (throttle valve) followed
by the part number. Just below we find the unique identifier of the test. In the upper
right corner we can see what page we are on.
In the example we can see that the tested device is an EGR with part number AF07676 and
that the test identifier is 03097785_17D296ABEC3.
At the bottom we will see the icon indicating that, in this activation of the
example, the test has been successful. This means that the signal has not gone outside
the limits defined by the tolerance at any time.
With the buttons and we can move between the four graphs.
On the last page (4/4) there will be a button to return to the initial menu and
to repeat the test on the same valve.

is displayed at the bottom, indicating that the verification
In the second test,
did not pass successfully.
This means that the signal has gone beyond the limits set by the tolerance at some
point during the activation, as we can see in the example.
Note: If a signal has produced a fault, all points of the signal that are out of tolerance
during activation will be marked in red.

Some throttle valves have a second sensor. In this case, the secondary sensor will
be displayed in a magenta tone (both signal and tolerance).

8. Test result
The favorable result of the tests implies that the tested valve is within the specifications
and operating tolerances approved by the manufacturer and the quality control of Alfa
e-Parts.
An unfavorable test result indicates that the operation of the testedvalve exceeds the
limits set for its correct operation.
In the event that the valve tested with an unfavorable result is within the stipulated
warranty period, it must be sent to Alfa e-Parts, together with the ID of the test, for
examination in the laboratory and to determine the cause of its failure. For this process,
you must follow the guarantee protocol established by Alfa e-Parts.
Any manipulation, modification or foreign body found in the valve will cause the loss of
the guarantee and will be returned toits sender.
Before turning off the tester:
Once the verification is finished, if the machine is connected to the internet, we must
wait a few seconds before stopping it so that it can correctly send the captured
data. During this time,we can take the opportunity to disconnect the adapter cable
from the valve and from the tester.
Note: It is important to disconnect the connectors with caution.You should always pull on
the connector, never on the cable. Otherwise the wiring could be damaged.
