g.

Open fluid inlet valves (FV). Check for leaks.

Do not operate HFR without all covers and shrouds in place.

1.

Use feed pumps to load fluid

NOTE:

The HFR is tested with oil at the factory. Flush out the oil with a compatible solvent before dispensing. See

Flushing on page 52.

a.

Check that all machine connections are setup.

See Setup procedure, page 38.

b.

Check that inlet screens are clean before daily

startup, see page 56.

c.

Check level and condition of ISO lube daily, see

IsoGuard Select

Turn on component B (Blue) and component A

(Red) agitators, if used.

SA e.

Turn both PRESSURE RELIEF/DISPENSE valves (SA, SB) to DISPENSE .

Keep Components A (Red) and B (Blue) Separate

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (Red) and component B (Blue) parts. h.

Use feed pumps to load system. i.

For models with an EP, Fusion, or P2 gun only, hold gun fluid manifold over two grounded waste containers. Open gun fluid valves A (Red) and B (Blue) until clean, air-free fluid comes from valves. Close valves.

f.

Start feed pumps.

For models with an MD2 Valve only, hold

MD2 valve nose piece, without a mixer installed, over two grounded waste containers. Leave mixer off and trigger gun until both fluids flow freely from the nose piece without any air.

k.

To prime the pump, cycle the pump a few times or until air-free fluid dispenses.

Calibrate HFR

The HFR calibration procedure is a two step process.

The first step, Learn Mode, must be performed whenever the pump line is rebuilt or if any other maintenance is performed that may affect the mechanical tolerances in the pump line. If the machine does not appear to be utilizing the full extent of the pump stroke, or if the machine appears to be contacting the end of the hydraulic cylinder, follow the Learn Mode procedure.

The Learn Mode procedure will teach the system the mechanical limits of travel.

Learn Mode Procedure: a.

Navigate to the Calibration screen.

b.

Press the Learn Mode Calibration button and set the mode to run as the dispense applicator that is installed on the system.

NOTE: For circulation systems, set the mode as either

EP or MD2 valves. These settings will not dispense material.

c.

Place a waste container below the dispense valve. The next steps will cause the machine to dispense material for all other settings.

NOTE: During this process, the system learned the mechanical limits of travel. If the pump did not reach both the left and right extreme limits for any reason, repeat the procedure.

If the system is to be used in a Time or Volume Dispense Mode, system calibration is complete after the

Learn Mode procedure described above. However, if the system is to be used in Weight Dispense mode and the application requires that the dispense amount be accurate and consistent then the weight calibration procedure below must be followed.

Weight Calibration Procedure:

NOTE: Only perform Weight Calibration procedure if the system will be run in Weight Dispense mode.

The Weight Calibration procedure must be run with the system production-ready. Orifice sizes and hose lengths must be finalized, material should be at temperature and any conditioning zones that will be on during production should be turned on. Any variation in system setup between when this procedure is run and the production environment will result in a decrease is system dispense accuracy.

a.

Navigate to the Weight Calibration screen . b.

Navigate to the Cal. Setpoint text box then enter the desired set point (pressure or flow, based on selected Control Mode).

d.

Press the go right button and then the dispense button . The pump will travel to the right most extreme position.

e.

After the pump stops moving, press the go left button and then press the dispense button . The pump will travel to the left most extreme position.

f.

After the pump stops moving, press the continue button to go on to the next step in the calibration process or the page back button to return to the main Calibration screen.

c.

Press .

d.

Put a waste container under the dispense valve.

e.

Press or the footswitch to start the system characterization process. The pump will start to operate at the entered setpoint until it learns the proper control parameters, then repeat the process at 60% of that value. When it is complete, the icon will change back to .

f.

Press again to deactivate.

g.

Select the Cal. Point 1 of 2 text box under the scale graphic.

Startup h.

With a waste container under the dispense valve, press or the footswitch to dispense a

Cal. 1 shot. Discard the dispensed material. i.

Select the Cal. 1 Shot Average field then press

to erase the value.

j.

Select the Cal. Point 1 of 2 text box.

k.

Press or the footswitch to dispense a Cal. 1 shot.

l.

Weight the material dispensed and enter the weight in the text box.

m. Repeat the previous two steps three more times. The logic will automatically average the readings and provide the result in the second text box in the row.

n.

Select the Cal. Point 2 of 2 text box under the scale graphic.

o.

Press or the footswitch to dispense a Cal. 2 shot.

p.

Weight the dispensed material and enter the weight in the text box.

q.

Repeat the previous two steps three more times. The logic will automatically average the readings and provide the result in the second text box in the row.

r.

Press .

The system is now able to dispense accurate material amounts for the setpoint provided during the process. If a weight dispense operation uses a setpoint significantly different from the setpoint used in during calibration an advisory will be provided to inform the user that the dispense accuracy may be degraded.

3.

Set temperatures (Heated models only)

This equipment is used with heated fluid, which can cause equipment surfaces to become very hot. To avoid severe burns:

• Do not touch hot fluid or equipment.

• Allow equipment to cool completely before touching it.

• Wear gloves if fluid temperature exceeds 110°F

(43°C).

For detailed temperature adjustments, including alarm levels, or upon initial machine configuration, see Conditioning Screen 2 on page 77 for details. For minor adjustments to the temperature setpoint once the machine has been initially configured, see the Status

Screen on page 85.

4.

Set system control and dispense modes: See

System Screen 1 on page 73.

5.

Set pump sizes: See System Screen 1 on page 73.

6.

Define Shot Recipes a.

Navigate to the Shots screen.

b.

Press to enter the screen.

c.

Use the directional keypad to navigate to the shot detail column for the desired shot number.

d.

Type the desired setting for that item then press . e.

Repeat the previous two steps for all desired shot numbers.
