general information.

1. This Service Guide provide s you with all technical inf ormation relating to the BASIC
CONFIGURA TION decided for Acer’s “global” product offering. To better fit local
market requirements and enhance product competitiveness, your regional office MAY
have decided to extend the functionality of a ma chine (e.g. add-on card, mode m, or
extra memory ca pa bility). These LOCALIZED FEA TURES will NOT be covered
in this generic service guide. In such ca ses, ple ase contact your region al off ices or the

responsible personnel/cha nnel to provide you with further technical details.

2. Plea se note WHEN OR DERING FRU PARTS, that you should check the most up-

to-date information available on your region al web or channel. If, f or whatever reason,

a part number cha nge is ma de, it will not be noted in the printed Service Guide. For

ACER-AUTHORIZED SERVICE PROVIDERS, your Acer office may have a DIFFER

ENT part number code to those given in the FRU list of this printed Service Guide.
You MUST use the list provided by your regional Acer of fice to order FRU parts f or
repair and service of customer machines.

Lamp Specification

1.Product Scope

The product is a lamp system consisting of a short arc burner in a reflector, and a lamp
driver.

Lamp type UHP 200W-150W 1.0

Driver type EUC 200V/01 TopValue

2. SYSTEM SPECIFICATIONS

2.1 Driver conditions

See driver specifications for more information
EUC 200V/01

* If the lamp voltage is below 35V continued over 90s, the driver shuts down.

** If the lamp voltage reaches over 140V, the driver shuts down immediately.

2.2 Run-up time

Run-up time to 80% of the stabilised luminous output is < 60s.

2.3 Ignition

2.3.1 Cold ignition

The criterion for reliable ignition is defined as a maximum of three ignition
failures on 30 attempts per amp however none of these ignition failures
may occur subsequently.
During the ignition phase of the lamp (run-up-time), no cooling of the burner
recommended. Cooling of the burner can lead to ignition failure.

3 Chapter 1

It is known that asymmetric cooling after switching the lamp off, can lead to
ignition failure in the next attempt due to condensed mercury on 1 of the electrodes.
Therefore Philips advises to build in multiple attempts (max. 5 for safety reasons) to
start the lamp. Between 2 attempts one has to wait 15s.
Philips suggests after a successful starting attempt to keep the lamp burning for
at least 15 minutes.
The cable has an isolation value of 2.5kV
To limit voltage loss of the ignition pulse, the mutual capacity of the cables may
not exceed 40pF.
To ensure this, Philips recommends to:

Avoid twisted cables
Never tie the cables together

Avoid contact to conductive plates, especially if those are connected to ground

(e.g. via PE)

If possible keep the cables straightened having a mutual distance (of 1 to 2 cm

between the

A suitable electrical enclosure should be provided in the end-product. Creepage
and clearance distances to high voltage parts and traces have to be evaluated in
the end-product. Special consideration has to be given to the distances from earthed
mounting screws to hazardous voltage traces on the lamp driver PCB.

2.3.2 Hot restrike

At max. bulb temperature of 300 oC+ -25oC : 98% ignition reliability of the total
number of switches.
At max. bulb temperature of 300 oC+ -25oC : 99.9% ignition reliability of the total
number of switches.
A restrike of the system can be applied 15 seconds after shut down.
Restrikes of the system can be repeated up to max. 5 times, if the lamp has not
successfully started from the first time.
Philips suggests after a successful starting attempt to keep the lamp burning for at
least 15 minutes.

4 INSTRUCTION FOR USE

- To replace the lamp, the power should be switched off.

- The burning position is horizontal ± 20°.

- Never touch the burner or reflector mirror with bare hands. If bare hands have touched
it, it should be cleaned with a lint free towel before installing the lamp.

- The lamp should be operated on the lamp driver as mentioned in paragraph 1.

- Fast switching cycles will reduce lamp life (e.g. 10min on 10min off).

- Max torque on the side and centre connector: 0.8Nm.

- The screw, which connects the cable with the side connector, may not touch the

reflector surface.

- The set maker must design a lamp house to keep glass pieces in the lamp house.

- Visible arc instability has to be suppressed by set optics.

5 ENVIRONMENTAL LAWS

EU

At end of service life, UHP Lamps should be treated as chemical waste (in view of
mercury content), and be
disposed of in compliance with national regulations/law.

USA

To comply in accordance with the Law of Vermont, that obliges the visible notification
on a lamp in case it
contains mercury, a Hg logo will be added on the reflector of the lamp. Besides the
reflector, also lamp
packaging with destination USA needs to notify the customer that the packaging
contains mercury added
products.
For more information about Hg marking, check the website of the Law of Vermont.
