Setup
206BBefore you operate the system, know the system components. Complete the steps
instructed below for safe and correct operation. Refer to the separate Installation
Guidelines for information on transportation and unpacking.
422BWarning: The following procedures should be done by qualified persons in accordance
with this manual and applicable safety regulations. A “qualified person” is defined as
“a person or persons who, by possession of a recognized degree or certificate or
professional training, or who, by extensive knowledge, training, and experience, has
successfully demonstrated the ability to solve problems relating to the subject
matter and work.” (ref. ANSI/ASME B30.2-1983.)
Installation
1. 36BPlug the machine into an appropriate power source. Refer to the legend plate on the
electrical enclosure door. The electrical service should be correctly grounded and
the power source clean. A line conditioner may be necessary if there is high power
equipment operating off the same source. Poor quality power can cause errors.
423BWarning: Failure to comply with electrical specifications can cause machine damage
and injury to installation personnel. Electrical hookups must be made by a qualified
electrician and comply with any applicable local standards.
2. 37BConnect the ¼” NPT female fitting at the rear of the machine to a source of clean,
dry air. A hose of ¼” inside diameter is sufficient.
3. 38BClose any access doors and engage the “Emergency Stop” button.
4. 39BTurn the main air supply to “SUP”.
5. 40BTurn the power switch on the electrical enclosure to “On”.

Revision D /January 2022 Page 12 of 47
6. Install the appropriate exhaust for your system. 600 CFM is required for each exhaust
blower connection. If your system has only top side lamps (or bottom side only), you
will only need one 600 CFM exhaust connection. If your Spectra has both top and
bottom side lamps, you will need two separate 600 CFM exhaust connections. The
facility exhaust must be able to draw 600 CFM at the inlet connection to the Spectra.
7. Ensure that the blower(s) in the Spectra are spinning in the correct direction. With the
factory exhaust connection disconnected, turn the blower on and make sure the
exhaust is coming out of the Spectra. Refer to Section 9.2 on how to turn the fans on
via the HMI.
8. If the blowers are running backwards, turn main power switch off then swap any two
incoming power legs feeding the blower.

been adjusted, use the hand crank to adjust the conveyor width.
1. 41BPut a board on the conveyor.
2. 42BTurn the hand crank clockwise to decrease the conveyor width or counterclockwise
to increase the conveyor width.
2BFigure 4: Hand Crank
3. 43BMove the board back and forth on the conveyor to make sure that it slides smoothly
and does not catch or drag. Continue to adjust the width as necessary.

Spectra UV
Revision D /January 2022 Page 14 of 47
SMEMA
210BFor manufacturing lines with conveyor systems, the SMEMA and Intermodule cables must
be correctly connected.
424BNote: On the diagrams, the J# refers to the label on the machine, not the label on the
cable.
211BThe Surface Mount Equipment Manufacturers Association (SMEMA) Electrical Equipment
Interface Standard is used to make sure the sequence of boards is correct. If these
connections are not in place, boards cannot move from one machine to another. SMEMA
cables have male 14-pin amp-type CPC connectors. The cables are straight-through so
orientation does not matter.
212BOn each module, the wire to the J1 plug must connect to the J2 plug on the machine
upstream. Similarly, the J2 plug on each machine must connect to the J1 plug on the
machine downstream, as shown in the following diagram:
