1. Product Description
The UV drying systems manufactured by GEW (EC) Limited are designed for the instantaneous
drying of inks, varnishes and adhesives that are sensitive to ultra violet (UV) light.
A typical web colour printing press comprises several printing stations in line, each station applying
ink of a different colour. The ink printed on the first station must be thoroughly dry before entering
the second station to avoid contaminating the press. A drying unit containing a high power UV
lamp is located between print stations. The web passes through a ‘web slot' in the drier and travels
past the lamp. UV drying is effectively instantaneous, allowing the press to be run at high speed.
An extra drying unit may be located at the end of the web for drying varnish applied after the final
printing.
The
e
-Brick is a highly integrated power supply designed specifically for powering UV lamps in
drying systems. The
e
-Brick features integrated controls and all necessary hardware to control
the UV system including lamp cooling, safety interlock features, and a press interface allowing the
UV curing to be controlled automatically.
The
e
-Brick power supply is a component part of a GEW UV drying system. A complete system
would also include GEW UV dryer(s) e.g. VCP, custom cabling, fan cooling, ducting and a human
machine interface (HMI) to control the operation of the system. Systems vary in complexity and the
scope of supply differs depending on the application; all systems require commissioning by trained
personnel.
This manual should be referred to alongside the user manuals and installation information for the
other components in the system.
This user manual has been prepared in accordance with the guidelines set out in EN12100 and
EN60204.

If you experience difficulties in setting up this product, contact GEW at the address given at the
front of this manual. If in doubt, ask! We are always ready to help.
3.5.1. Installation
e
-Brick systems should be installed by GEW service technicians or, alternatively, by GEW
factory trained personnel. To validate the system warranty, a system specific code must be
entered on completion of installation and commissioning. When a system has not been
commissioned by GEW, a message will appear on the HMI every 20 hours reminding the
customer that the system is not under warranty:
“SYSTEM NOT UNDER WARRANTY. PLEASE CONTACT GEW, TEL: +44 (0)1737 824510”
To validate the warranty, enter the password supplied by GEW service.
3.5.2. Modifications
Each GEW UV system is engineered to meet the requirements of a given installation. Any
change in requirements may require re-commissioning or modification of the system; always
refer to GEW for advice before attempting to modify the UV system.
3.5.3. Markings and tamper evident seals
GEW products are clearly marked with safety warnings to draw attention to specific hazards.
Due to the hazardous voltages within the
e
-Brick, security screws are used to secure the
housing; in addition, tamper evident seals (see Figure 6) are fitted to indicate that covers
have been removed. If these seals are broken or damaged the GEW warranty will be void.
Figure 6: Tamper evident seal
3.5.4. Location of equipment
The user should ensure that no electrical controls are obstructed. Always site equipment to
allow reasonable access for servicing.
The installer should ensure that clearances around the equipment fall within the safety
regulations for use of electrical equipment. Impact from vehicles such as forklift trucks must
be prevented, typically by installing a protective crash barrier. This is the responsibility of the
customer.
Loose cables between distribution panels, the printing machine and the UV dryers must be
protected by galvanized trunking. This is the responsibility of the customer.

supply is on; the second indicates that the main contactor (K1) is enabled and that the
e
-
Brick output is on.
4.4.3. System Emergency stop
The
e
-Brick can only be enabled if the system emergency stop (E-stop) contacts on the
Press connector [P1] are closed, enabling the internal safety relay. The internal controls
monitor the E-stop status using auxiliary contacts on the safety relay; as a safety measure,
the relay can still disable the supply in the event of a control failure.
Warning! Refer to 5.4 for essential safety information relating to E-stop usage.
4.4.4. Contactor
The 3phase power to the main converter in the
e
-Brick is switched on using an internal
contactor. By design, the contactor coil can only be energised when the press E-stop is
enabled and a second relay is switched on. The second relay is switched on by the
embedded controller and is enabled from the HMI screen.
4.4.5. Temperature & cooling
Fan failure detection Generates warning to HMI
Internal temperature warning Generates warning to HMI
Over temperature trip Automatic shutdown of
e
-Brick
4.4.6. Output protection
Voltage limit Output voltage is limited to a specified maximum
Current limit Output current is limited to specified maximum
Short circuit protection Output circuitry will tolerate an indefinite short circuit
Warning! Under no circumstances should either lamp output terminal be electrically connected
to chassis ground; this will invalidate the
e
-Brick warranty and is likely to result in severe damage
to the
e
-Brick.
