YDT262 Operating and Servicing Manual DELPHI DIESEL AFTERMARKET
6 HL018, Issue 2
1. Introduction
The Dynamic Timing Control Box (YDT262) is used to determine the timing position of diesel fuel
injection pumps. It is used in conjunction with a host test bench (to mount and drive the fuel pump), a
rotary encoder (providing angular position information), and a piezo pickup (giving the point of
injection signal).
2. Definition of Terms and Abbreviations
The following terms and abbreviations are used in this manual and/or in the YDT262 software.
SP Start Position. The box records a reference point for starting position (effectively
0 degrees). This is used later when calculating the Overcheck Angle.
Offset The angular offset to be applied from the point of injection to the locking position.
Trigger Level The piezo signal trigger level at which the angular position is recorded.
POI Point of Injection
RLP Required Locking Position. This is equal to POI plus/minus the Offset.
Overcheck Angle The difference between SP and RLP.
3. Principle of Operation
The rotary encoder is mounted on the pump drive coupling and the piezo pickup is connected to one
of the pump delivery valves. The piezo pickup provides a signal once every revolution at the point of
injection. By comparing this signal with the angular position information from the rotary encoder, the
point of injection angle is found.
The actual position is found by taking a number of samples at a given speed. The software then
calculates the average position and, once the drive has been stopped, provides you with an angular
countdown so that you can rotate the pump around to that position.

4.2 Installation
The YDT262 requires a standard IEC single-phase power lead, to be purchased locally. An EMC
shielding ferrite is supplied with the kit. Clip the ferrite onto the single-phase power lead as shown in
Figure 4.3.

The YDT262 is designed to hang on the rim of the test stand. If using with Pumpmaster, AVM, or
PGM test stands, the additional adapter bracket will also be required.
4.3 Software Operating Sequence
The operating sequence for the box together with examples of the screen displays is given below.
Operating Step
Display Example
Power on
The display shows the version number and the last-used language.
Press Up/Down buttons to change language. Press Enter to
confirm and move on; the box records SP at this point.
VERSION 1.0
ENGLISH
Zero Angle Confirmation
The software confirms that the zero angle (SP) has been recorded.
Up/Down buttons disabled. Press Enter to confirm and move on.
If unsuccessful, the message “ZERO ANGLE ERROR” will be
displayed and all buttons will be disabled –refer to Section 5.3
Troubleshooting.
ZERO ANGLE
RECORDED
Offset Value
Display shows last-used offset value. Press Up/Down buttons to
change, scroll from 0.0 to 359.9in steps of 0.1. Press Enter to
confirm and move on.
OFFSET: 0.0 DEG
Trigger level setting
Display shows last-used trigger level. Press Up/Down buttons to
change –the following levels are available: 25%, 50%, 72%, 75%
of peak voltage, or 100mV, 200mV, 400mV, 800mV. Press Enter to
confirm and move on.
TRIGGER LEVEL:
25%
Variation
Display shows the angle between piezo signals. This gives an
indication of any problems with the input signals (it should read
360when the pump is running at constant speed). Press Enter
when value is stable and ready to test. Up/down buttons disabled.
VARIATION
359.8 DEG
Sampling
The box takes 100 samples of the piezo position, then calculates
RLP. All buttons are disabled during learning.

4.4 Setting / Overchecking the Timing Position
For details on setting and overchecking the timing position, refer to Delphi Service Instruction Note
number DT339.
4.5 Downloading an Alternate Language
The YDT262 is supplied pre-loaded with the following languages: English, French, German, Italian,
Spanish, and Portuguese. There is additional space allocated in the memory for one extra language,
which can be downloaded into the YDT262 from a PC.
When there is no additional language loaded the message “USER NOT AVALABLE” will appear when
you scroll through the languages. To escape from this message, press the Enter button.
To download an alternate language you will need the following:
Any PC with a serial communications program, e.g. Terminal or HyperTerminal (these are
standard programs supplied with Windows 3.x, 95, 98, and NT).
A standard 9-way D female to 9-way D female serial cable, e.g. RS Components part no. 215-
410.
Before downloading, you need to create the alternate language messages as a text file. An example
text file is given below (with English messages). Open Notepad and copy this example file,
translating where required. Note that each line can only have 20 characters maximum. Put 2
semicolons on the last line of the file as given in the example. Save the file and close Notepad.

The procedure below refers to HyperTerminal. Other programs will be similar –the important
information is the COM port setup given in steps 4 and 5; refer to the operating instructions for your
particular program to set these.
1. Connect the cable between the YDT262 and one of the PC COM ports. Do not switch on the
YDT262 yet.
2. The first time you use HyperTerminal you will need to configure the communication settings. To
do this, open HyperTerminal (Start > Programs > Accessories > HyperTerminal > HyperTerminal).
It will assume you are making a new connection. Enter a name for the connection, e.g. YDT262,
choose an icon, then press OK.
3. In the next box select the COM port you are using and press OK.
4. In the next box, configure the port as follows, and then press OK. Baud: 9600; Data Bits: 8;
Parity: None; Stop Bits: 1; Flow Control: None.
5. Under ASCII setup (File, Properties, Settings, ASCII Setup), ensure that the “Send line ends with
line feeds” option is selected, then click OK twice to return to the main screen.
6. Choose File, Save. This saves the connection information as a HyperTerminal file, and puts a
link to it on the Start menu. Next time, you can just click on this link (Start > Programs >
Accessories > HyperTerminal > YDT262.ht) and it will open HyperTerminal with the correct
settings.
7. Switch on the YDT262 while holding down the Up and Down buttons. The message “SEND
TEXT” will appear on the display. You are now ready to transfer the language file.
8. In HyperTerminal select Transfer, Send Text File, and then browse to find your language text file
and select Open.
9. When the download is complete, the box will display “READY”. Press Enter to return to normal
operating mode.
