Overview The HD Series Electric Gun Driver (HD gun driver) represents three types ofgun drivers: HD2A, HD2B, and HD4A.

HD gun drivers enhance performance of automatic guns by producingextremely fast valve action. HD gun drivers ensure precise adhesivedeposits by delivering high voltage DC power to the electric applicator coils,providing sharper cutoff and increased pattern placement accuracy.

The information in this manual is generally common to the three HD gundrivers. Differences are noted where applicable.

Description The following information provides a system description of the three HD gundrivers.

HD2A Gun Driver The HD2A gun driver accepts two independent inputs from a patterncontroller or a 5−24 VDC input source, and provides two independentoutputs. The two inputs can be connected so that a single input drives boththe outputs. Each output can drive up to four standard E100/M100/EM100automatic modules or eight E900/EM900 automatic modules. The HD2A

gun driver has two 8-position DIP switches and one 4-position DIP switch toconfigure the performance settings.

� Duration mode maintenance cycle settings



Installation This section provides information to position and connect the HD gundrivers.

Unpacking and Positioning the HD Gun Drivers The HD gun driver kit includes all the mounting hardware, conduit holes forpower hook up, timer input signal and output wires.

1. Exercise care to prevent equipment damage during unpacking.

2. Inspect for any damage that may have occurred during shipping. Reportany damage to a Nordson representative.

3. Install the HD gun driver close to the pattern controller and melter butaway from excessive vibration or moisture.

4. Mount the HD gun driver, refer to Figures 4 and 5 in Dimensions.

Electrical Connections

WARNING: HD gun drivers are designed for use with specific automaticguns, photosensors, pattern controllers, or customer-supplied timers. Donot connect HD gun drivers to any other device. Serious injury or propertydamage may occur.

WARNING: HD gun drivers produce a high voltage DC signal that couldcause fatal injury. Disconnect power at power source and wait 3 minutes forcapacitor to discharge before performing maintenance to this or any otheradhesive system component, such as wiring, plugs or terminal connectors.

Make sure that the DC output signal wires from the HD gun drivers aresufficiently rated to withstand a voltage of 600 volts, 0.620 mm2 (20 AWG)wire or equivalent.

WARNING: Automatic guns must be completely isolated from all othercircuits. Do not attempt to connect this gun driver through test circuits(provided on systems or other equipment). Consult a Nordsonrepresentative for any questions regarding installation.



WARNING: HD gun drivers must be properly grounded and fusedaccording to its rated current consumption. Failure to follow the safetyprocedures can result in serious injury.

CAUTION: When a recommended pattern controller is used, all signaloutputs are optically isolated. If another type of pattern controller is used,isolate the PELV (Protective Extra Low Voltage) circuits before connectingthe output signal from pattern controller/input to the HD gun drivers.

Plan the wiring route carefully as they are an integral part of a successfulinstallation. Consult a Nordson representative for recommended cables.

1. Connect the HD gun driver to a ground for safe operation. Verify that allconduit and cabling shields are properly grounded.

NOTE: If the HD gun driver ships from the factory as part of a system, itcomes grounded to the melter chassis.

2. Connect the HD gun driver to a fuse-protected switched circuit. The HD gun driver is fused with two 2.5 A slow-blow fuses, and is connectedto the melter�s main circuit breaker.

3. Use separate shielded cables for each signal line. Signal wiringincludes photosensors, tach generator, and communication wiring.

4. Use the twisted pair wire for HD gun driver output.

5. Connect the power cables to a grounded conduit. Run the signal wiring,power wiring and HD gun driver output separately if possible. Do notrun all three together. If the signal and the power wiring must share thesame conduit, the signal leads must be completely shielded.

NOTE: The signal and power wiring should be as short as possible.

6. Install the pattern controllers and peripherals away from electrical noisesources such as transformers, motors, high voltage lines, large powerswitches, or welders.



HD Gun Driver Configuration HD gun drivers are configured at the factory according to customerspecifications. If application requirements do not change, the factorysettings will be sufficient for normal operation.

The following factors can affect HD gun driver performance andconfiguration settings:

� AC source voltage

� Ambient temperature

� Adhesive pressure

� Type of gun (number of modules per gun)

� Module coil voltage rating

� Adhesive viscosity

� Module style

� ON/OFF cycle rate (glue and gap lengths)



HD2A Gun Driver Configuration The three variables that determine the configuration of the HD2A are:

� Maintenance cycle switches for Output 1 and output 2

� Input signal configuration

� Output signal configuration

Re-Installing the HD Gun Driver Module After reconfiguring the HD gun driver, re-install the HD gun driver module.

Make sure that the switches on new HD gun driver module are set to matchthose on the module being removed.

1. Connect the ground wire to bottom of the HD gun driver module.

2. Reattach the five orange plastic connectors to the new control panel inthe module enclosure.

CAUTION: Verify that the wires are not pinched between the connectors.

3. Tighten the four screws loosened in step 2 under Removing the HD gunDriver Module.



Startup WARNING: The HD gun driver must be properly grounded and fusedaccording to its rated current consumption. Failure to follow safetyprocedures can result in serious injury.

Once the HD gun driver has been installed, it may be turned on by pressingthe ON/OFF switch.

� When the HD gun driver is in operation the power indicatorilluminates with a yellow light.

� When the HD gun driver is not in operation the power indicatorremains illuminated until the capacitor discharges.

Maintenance WARNING: HD gun drivers produce a high voltage DC signal that couldcause fatal injury. Disconnect power at power source and wait threeapproximately three (3) minutes for the capacitor to discharge beforeperforming any maintenance procedures to this or any other adhesivesystem component, such as wiring, plugs or terminal connectors.

WARNING: Allow only personnel with appropriate training and experienceto operate or service the equipment. The use of untrained or inexperiencedpersonnel to operate or service the equipment can result in injury, includingdeath, to themselves and others, and damage to the equipment.

WARNING: When damaged parts pose a risk to the operational safety ofthe unit and/or safety of personnel, switch off the unit and have thedamaged parts replaced by qualified personnel. Use only original Nordsonspare parts.

Preventive Maintenance Nordson recommends that the HD gun driver undergo preventivemaintenance as required. Maintenance is important for operating safetyand extending the operational lifetime of the HD gun driver. The frequencyof maintenance is dependent on the operating environment of the HD gundriver.

Observe the following preventive measures:

� Keep the HD gun driver module free of dust

� Clean the HD gun driver module at least once a year



Troubleshooting WARNING: Allow only qualified personnel to perform the following tasks.Follow the safety instructions in this document and all other relateddocumentation.

This section contains troubleshooting procedures that cover only the mostcommon problems. If the problems cannot be solved with the informationgiven here, contact the local Nordson representative.

Problem Corrective Action

1. Power Indicator does not illuminatewhen Power Switch is in the ONposition

Check the input voltage between terminals L1 and L2. If thevoltage is present (90−260 VAC), replace the HD gun driver.

2. No input signal light Check trigger signal polarity. The voltage must be between5−24 VDC. A green signal light shows trigger state. The HDgun driver does not need to be powered.

3. No output indicator light The front panel power switch must be in the ON position. TheRUN/OFF/TEST switch must be in the RUN position. The inputsignal light must be ON. If there is still no output light, replacethe HD gun driver.

4. No output to solenoid or valve coil If the output indicator light is on but there is no output to thesolenoid, check the wiring and the solenoid.

5. Electric guns fail to open, or fail toremain open for entire adhesivedispensing event

Request technical assistance from a factory representative.

Repair WARNING: HD gun drivers produce a high voltage DC signal that couldcause fatal injury. Disconnect power at power source and waitapproximately three (3) minutes for the capacitor to discharge beforeperforming any maintenance procedures to this or any other adhesivesystem component, such as wiring, plugs or terminal connectors.

CAUTION: The protection rating of the enclosure must be maintained afterinstallation or maintenance. If seals around the Lexan cover or hole plugsare broken, reseal with high temperature silicone to ensure the integrity ofenclosure.
