0.0 Description The LogiComm OEM Gun Driver Board is a high-performance, four-channel, current-mode electric applicator driver. The driver controls coil current, which is the driving force behind the actuation of the module on an electric applicator. The driver electrical output is a spiked waveform that applies a high peak current to actuate the module rapidly, followed by a lower holding current to reduce power dissipation. The waveform can be adjusted to suit the application. The driver is shipped with factory default value settings that should work for all applications with e.dot & e.dot+ modules. For other applications using different modules, the driver has a number of parameters than can usually be programmed to achieve the application objectives. Programming of the driver is accomplished through software shipped with the driver. Application parameters such as peak current, peak time and hold current can be entered into the software to meet appropriate module requirements. The driver has two operating modes: bead and dot. In the bead mode, the driver electrical output corresponds to the input trigger signal. In the dot mode, the driver output is actuated by the input trigger signal for a short, programmable time that is independent of the length of the trigger signal. To purge the applicator in the dot mode, in addition to the trigger signal a purge signal must be applied. Once the purge signal is active, the output is actuated for as long as the trigger remains active. The dot mode is useful for applications that involve very short beads being deposited at a position(location) determined by the pattern controller or PLC. The driver has a number of useful visual indicators that aid in troubleshooting, such as the POWER, TRIGGER, OUTPUT, and FAULT LEDs. The LogiComm OEM Gun Driver Board is just one part of an electric adhesive-dispensing system. When used together, the LogiComm OEM Gun Driver Board in combination with an electric applicator for hot melt (i.e. e.dot+ ) or in combination with an electric applicator for cold glue (i.e. the LA820), provide a powerful, high-performance solution for many adhesive-dispensing applications.

0.0..�.�.�.�.��涆�@ Bead Mode The gun output operates in BEAD MODE if zero time value is selected on the two DOT TIME setting switches. Value on both zero switches is “zero”.

In BEAD MODE the gun output is activated as long a trigger signal is present on the appropriate gun input. 0.0..�.�.�.�.��溘�@ Dot Mode DOT MODE is active as soon as a time value is selected on the DOT TIME setting switches. Dot Time value greater than 0 ms. The dot time can be adjusted between 0 – 4.95 ms using steps of 0.05 ms. The total dot time is the result of the time values set on both switches. The left switch provides a scale from 0- 9 representing a time range from 0 – 4.5ms The right switch provides a scale from 0- 9 representing a time range from 0 – 0.45ms The dot time setting needs to be conducted with a small screw driver. The arrow on the selection dial points on the set value.

Example: Switch 1 setpoint = 2 ~ (2 x 0.5 ms)= 1,00 ms Switch 2 setpoint = 7 ~ (7 x 0.05ms)= 0,35 ms ----------

Total DOT TIME 1.35 ms On the rising edge of the trigger signal the appropriate gun output is activated for the selected dot time. The yellow Purge / Dot Mode LED (ref. Fig.1, item 3) indicates the individual channel being in DOT MODE. The LED shines continuously when in DOT MODE and starts blinking when the channel is purged.

4.0 SET-UP Before placing the driver into routine operation, use the service software to ensure that the driver’s default settings will provide the desired performance and will not damage the applicator module coil(s). The driver is shipped with factory default value settings for e.dot guns. For other applications, the driver has a number of parameters that can usually be programmed to achieve the application objectives. Follow these steps to change any of the driver parameters. NOTE: Programming can generally be accomplished while the applicator is actuating. However, Nordson Corporation recommends temporarily disconnecting or disabling the trigger input to prevent applicator actuation. The driver is equipped with a USB connector type B (ref. Fig.2, item 12) to set-up the driver parameters. NOTE: To setup the driver a customer supplied cable with standard USB connector on one end and a small USB connector type B on the other end is required. To set up the driver to work with different types of electric modules the settings for each channel needs to be done via the USB port using the ship-with service software. According to the electric gun type in use the following settings need to be adjusted. PEAK CURRENT The peak current determines the maximum current the driver provides to the coil. This current is required to allow the coil to generate the magnetic force needed to, open the module. HOLD CURRENT The hold current determines the current that is required to hold the magnetic force level required to keep the module open PEAK TIME The peak time is the time required the peak current needs to flow through the coil to ensure the module opens properly.

Depending on the module type connected to each channel the settings must be done according to the following table. Module Type PEAK Current [A] HOLD Current [A] PEAK Time [ms]
