3.2.2.2 Checking the DLP connection
In the device manager, we should see two devices as “DLPGTwo_Device”, that means both side of
the DLP are connected.
Fig.56: Checking the Device Manager
► Open Device Manager.
► Check if Device Manager displays two
Imaging devices.
3.2.2.3 Checking the connection and firmware version of the DLP module
When the DLP module and the DMD module have been changed, a software check for the latest Ver-
sion is needed.
Requirements
●
Machine is switched on.
Fig.57: Checking connection and firmware
► Open DLPG2Library_Tester.exe
► Select ModuleID:=0 for Select Device,
press Connect (1).
► Check that the connection is successful,
i.e. status becomes open success and
Message box (2) shows Open DLPG2
Device Success.
► Press Get Version (3) to obtain version
numbers.
► Compare version numbers with the follow-
ing. If not the same, please contact with
the engineers in charge (mentioned in IN-
TRODUCTION section).
Repeat steps with ModuleID:=1.

Removal and Installation
Fig.58: Removing the screws
► Remove the two screws(1) using an Allen
T shaped Allen key size 2.0.
► Carefully pull out the encoder reader(2).
The scale of the scale bars
CAUTION!
Fingerprints or scratches damage the
scale bars(3) which then need to be
exchanged.
Do not touch or scratch the scale of the
scale bars.
Be careful when pulling out the reader
and when putting it back again.
.
Fig.59: Changing the reader
► Change the reader including the en-
coder(1) and all cables.
► Replace the encoder and the reader.

Fig.60: Calibration of the new reader
► Check the gap between the encoder
reader(1) and the scale bar(2) by using
the spacer(3) provided.
► The gap between the encoder reader and
the scale bar must be 2.1 mm.
► Calibrate the new reader. See the external
Power Point file “Y1Y2 ENC install & ad-
just procedure”.
► Move the gantry slowly the whole travel
range backwards. Whilst doing that check
the light at the indicator.
► If the lights are not within the color range
the holder needs adjustments. See 3.3.2
"Color code for the encoder readers"
[}51].
► Proceed the same way with all other en-
coder readers.
3.3.2 Color code for the encoder readers
Color Indication Adjustment requirement
Purple Optimum set-up No
Blue Good set-up No
Green Good set-up No
Orange Acceptable set-up but below recommendation level. Yes, angle and gap.
Red Poor set-up, signal maybe too low for reliable oper-
ation
Yes, angle and gap.
