2Getting Started
Read the sections on Safety and Specifications and check the PP600 fulfils
your requirements. See inside the front cover for other Gardasoft Vision
lighting controllers.
Connect the PP600 up to a supply and an LED lighting unit as described in
“Connections.” Note that the supply voltage must be connected to three
terminals. When the PP600 powers up it should show two alternating lines on
the display to indicate that it is operating properly.
Read the section on “Operation” and use the Simple Set Up to make the PP600
supply a small continuous current to the LED unit. Check that the LED unit
illuminates.
Users who have a PP610 or PP612 should refer to the PP610 section and read
how to send RS232 commands.
Mount the PP600 as described in “Mechanical Fixing” using a DIN rail or the
mounting holes. In particular read the notes on heatsinking.
Set up the PP600 for the desired operation and test.
See the appendix on Application Notes for additional information on the use of
the PP600. Visit www.gardasoft.com for more Application Notes.
Throughout this manual, references to the PP600 refer to all variants in the
PP600 range unless otherwise stated. The symbol “us” is used to denote
microseconds.

3.1.1 PP600 – Safety
Please read this before using the PP600 family of products. If in doubt, contact
your distributor or Gardasoft Vision.
Where this symbol appears in the manual, refer to the text for
precautions to be taken.
3.1.2 Heat
The PP600 can get very hot. It should be positioned where personnel
cannot accidentally touch it and away from flammable materials.
Do not exceed the power ratings given in the manual. Note that at the
maximum ratings the case temperature can reach 80oC.
If the output load is short circuited then the heat dissipated within the unit will
greatly increase, resulting in a further rise in temperature.
3.1.3 Electrical
The user must ensure that the potential difference between any combination of
applied signals does not exceed the supply voltage. WARNING: Higher
voltages may cause a danger to personal health.
The PP600 does not have complete tracking isolation of inputs and outputs.
Transients caused by inductive loads must be suppressed external to the PP600.
The metal case is not connected to PSU 0v. This is a change from previous
revisions of the PP600.
3.1.4 General
The PP600 must not be used in an application where its failure could cause a
danger to personal health or damage to other equipment.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

4.1.1 Sicherheitshinweis PP600
Bitte lesen Sie sich diesen Sicherheitshinweis gründlich durch, bevor
Sie die Produkte der Serie PP600 benutzen. Sollten dennoch Zweifel
Ihrerseits bestehen, zögern Sie nicht sich mit uns in Verbindung zu
setzen. Die Stellen im Handbuch, an denen dieses Symbol erscheint, beziehen
sich auf den Text zur Beachtung der Vorsichtsmaßnahmen.
4.1.2 Wärmeentwicklung
Die Geräte können während des Betriebes sehr heiss werden. Sie
sollten daher dort untergebracht sein, wo Personen keine
Brandverletzungen erleiden können und wo sich keine entflammbaren
Materialen befinden.
Überschreiten Sie nicht die im Manual angegeben Höchstspannungen.
Beachten Sie, dass die Temperaturen bei der maximalen Spannung 80 °C
betragen können.
Wird pro Kanal mit hohen Blitzspannungen und kurzen Blitzzeiten gearbeitet,
steigen die Temperaturen nochmals an!
4.1.3 Elektrischer Betrieb
Stellen Sie sicher, dass die Spannungsdifferenz bei keiner Kombination der
angelegten Signale die Versorgungsspannung übersteigt. ACHTUNG: Höhere
Spannungen können sich Gesundheitsgefährdend auswirken.
Ein- und Ausgänge haben keine komplette Leiterbahnisolierungen.
Überschläge, die aus Induktion resultieren können, müssen ausserhalb des
PP600 abgehalten werden.
Das Metallgehäuse ist nicht mit PSU 0V verbunden. Dies ist eine
Veränderung zu früheren Versionen des PP600!
4.1.4 Generell
Die Controller der PP600 Serie darf nicht in Applikationen eingesetzt werden,
in welchen ein Fehlverhalten des Gerätes gesundheitliche Schäden verursachen
könnte oder technische Ausrüstung zerstören könnte.
Wenn das Gerät auf nicht vom Hersteller spezifizierte Weise benutzt wird,
können seine Schutzvorrichtungen beeinträchtigt werden.

5General Description
The PP600 current controller provides repeatable intensity control of LED
lighting for machine vision applications. It includes the power supply, intensity
control, timing and triggering functions required for machine vision systems.
LED lighting needs a constant current supply as small variations in voltage can
cause large variations in light output. Currents can be specified in 0.25mA
steps below 1A and in 1mA steps above 1A.
Three modes of operation are provided separately for each channel:
Continuous:
In continuous mode the output is a continuous current.
Selected Continuous:
In selected continuous mode one or both inputs can be used to select an
output current. For each state of the inputs, the output current is fixed.
Strobed:
In this mode output is pulsed once per trigger. One input is used as a
trigger. The delay and pulse duration can range from 20us to 1 second in
20us or 2ms steps.
The PP600 is set up using four push buttons and a four digit seven-segment
display.
Configurations are saved in non-volatile memory so that the PP600 will resume
operation after a power cycle.

7Mechanical Fixing
The PP600 can be mounted onto a flat surface using the threaded holes in the
base, see diagram. The PP600 should only be mounted either vertically or with
its base horizontal. It should be mounted at least 15mm away from the sides
of plastic enclosures. Likewise leave a similar space between the PP600 and
any parts which could be affected by high temperatures.
The enclosure of the PP600 is used to dissipate power in the form of
heat. For this reason the material to which the unit is attached must be
suitable, preferably metallic with ability to dissipate the produced heat.
This is particularly important if the power dissipation of the PP600 (as defined
by PDthe section on Specifications) exceeds 10 Watts.
The PP701 kit is available for mounting the PP600 on a DIN rail.
The PP600 does not have an IP rating and should be mounted so that moisture
and dirt cannot enter the unit.

10
To avoid a fire hazard consider the implications of overheating in the
unlikely event of a fault in the PP600. The power dissipation in a fault
condition is approximately given by the sum of the following for
the two channels:
(<Power supply voltage> - <rated voltage for lighting>) * <max current delivered by Power supply>
Either limit the power supply output current(s) so that not more than 30W can
be dissipated in the PP600, or mount the unit in an enclosure.
To limit the power, set the power supply output voltages to the minimum value
required by the LED light and the PP600 together. Chose a PSU that limits its
output current by design, by setting the current limit on the supply (if this
feature exists) or use fuses. Remember to derate the fuse, if mounted in an
enclosure, as the temperature will be higher than ambient.
An enclosure may also be required for other parts of the system such as power
supplies and will provide mechanical and environmental protection in
industrial applications.
If an enclosure is used, the enclosure should be metal or plastic (with a
flammability rating of UL94 V1 or better); with no holes below or to the sides
of the PP600 when mounted. Cable entries below the PP600 should be via
glands that have a flammability rating as before. Observe the specified gap
between the PP600 and any other part or side of the enclosure.
