Gardasoft Vision also produce the PP101, an eight channel current controller with computer control. Connect the PP600F up to a supply and an LED lighting unit as described in “Connections.” Note that the supply voltage must be connected to three terminals. -

Page 7: General Description
General 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. -

Page 9: Mechanical Fixing
Mechanical 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. - Page 10 The PP600 does not have an IP rating and should be mounted so that moisture and dirt cannot enter the unit. 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>...
- Page 11 Connections General All connections except RS232 are available on screw terminals. The opto- isolated inputs require a voltage between 4.5v and 24v DC for a positive logic level. Open circuit or less than 1v gives a negative logic level. The case of the PP600 is not connected to the GND supply connection.

Page 12: Power Supply
GND, GND1 and GND2 must all be commoned. See section 9.2. Ensure that the wire gauge used for these connections is appropriate for the current to be drawn. Ideally, wires should be double crimped or independently secured to ensure they cannot come loose. Route low voltage and mains wiring separately. - Page 13 8.2.1 Single Supply Applications The diagram below shows the normal supply wiring scheme for the PP600. The three ground connections and VS connections are commoned. 8.2.2 Split Supply Applications It is possible to run the two channels and digital system from two or three separate supplies as shown below, though this will rarely be necessary.

Page 14: Operation
A trigger is a leading edge on an input signal, that is a transition from 0V to 5V on the input. On the PP600F range, output 1 can only be triggered from INPUT1 and output 2 can only be triggered from INPUT2. - Page 15 For selected continuous output the current is constant. The amount of current is selected using one or both digital inputs. Mode “SE 1” uses INPUT1 to select between two current values. When INPUT1 changes state the output current changes. Mode “SE 2” uses INPUT2 to select between two output currents.
- Page 16 Pulsed output Simple Set Up cannot be used to set up: Continuous output in steps of 0.25mA Continuous output, selected by digital input Setting current protection Extended Set Up can be used to set all features but is slightly more difficult to use.
- Page 17 9.3.6 Setting Up Continuous Output Continuous output can be set up using Simple Set Up. Set up continuous mode as follows. Note that pressing and holding MODE at any time will cancel the operation. Do not set the output current higher than the rating for the LEDs.
- Page 18 9.3.7 Setting Up Pulsed Operation Pulsed operation can be set up using Simple Set Up. PP600 is ready Press and hold SELECT for one second Use UP or DOWN to select which output channel to set up - "CH1" or "CH2".

Page 22: Command Structure
The PP610F and PP612F can be programmed via a serial communications link either from within the user’s custom code using MSCOMMS32.OCX or using the PP600COM DLL or OCX provided by Gardasoft Vision (see www.gardasoft.com). Alternatively a utility such as HyperTerminal running on a PC can be used to program an individual unit. - Page 23 If a command is invalid, one of the following error codes is echoed as well as being displayed on the LEDs. E33 Unrecognised command or parameters. E44 Illegal mode or channel number in command. Commands take effect immediately they are issued. Because of this, if the settings are being changed from high current Pulsed Output mode to a Continuous Output mode, it is advisable to set the current values to 0 using the RC command before changing mode.

Page 25: Continuous Output Mode
10.1.2 Continuous Output Mode In this case the mode of operation is selected and a single current output value defined. Set the mode of operation Syntax: RSfSm Where: f = output channel (1 or 2) m = 0 for continuous current Set the output current for the selected channel Syntax: RCfCcVvEe... - Page 26 c = output selection (0, 1, 2, or 3) v = output current (mA) e = (optional) maximum current rating of the LEDs. If it is not required, leave the Ee off the command. Note: This command must be sent for all output selections defined by the mode command.
- Page 27 m is the Mode 1 = Trigger on Input 1 2 = Trigger on Input 2 3 = Trigger on both Inputs p = pulse width (ms) d = delay before pulse (ms) The RT command will not allow a delay to be set which is less than the minimum for the current setting.
- Page 28 PP602F & PP612F – CCS Version The PP602F and PP612F have the same screw terminals as on the PP600F and PP610F. In addition they also have connectors for CCS lights. Power input and the digital inputs are only available on the screw terminals. The connectors are not labelled on the case.
- Page 29 Data on the RS232 port will increase the variation in the pulse delay but not the pulse width. After a trigger occurs, the PP600F halts all other operations while the pulse delay and pulse width periods occur. This means that if both trigger inputs happen simultaneously, then the output pulse for one trigger will be delayed until the other has finished.

Page 30: Error Codes
B. Error Codes Error codes may be displayed by the PP600. These are shown as “E nn”, where nn gives the number of the error. To cancel the error message, press “SELECT”. The error codes are: EC 1, EC 2 The current to one of the outputs has been turned off because the maximum output energy has been exceeded. - Page 32 Gardasoft LED Lighting Controllers The following products are available at the time of writing. New products will be introduced. See www.gardasoft.com for details of the current range. PP500 Range 2 output channels up to 10A each • 2 digital inputs •...
