SAFETY DURING INSTALLATION

Electrical

1. A protective electrical ground connection to a reliable earth ground is essential for safe operation. Without one, all acces- sible conductive components (including knobs and controls that appear insulated) can render an electric shock.

2. A disconnect switch with lockout capability must be provided between the power source and the equipment.

3. The power supply wire gauge and insulation must be sufficient to meet the temperature and power requirements.

4. Only fuses of the correct type voltage rating and current rating should be used. Refer to the Nordson equipment parts list for fuse recommendations. Using incorrect or nonrecommended fuses can present a fire hazard.

SAFETY DURING OPERATION

DO NOT operate Nordson equipment under the following conditions:

1. At a pressure higher than the rated maximum working pressure of any component in the system.

2. Near volatile or otherwise explosive gases or materials.

3. Without the covers, panel and safety guards properly installed.

4. At atmospheric temperatures below 20°F (-6°C) or above 120°F (50°C).

5. With hoses enclosed in any material that interferes with heat dissipation. This includes electrical conduit, insulation of any type or tight metal covers.

6. With large areas of hose in contact with a cold floor, cold sup- ports or other such surfaces. Cold points along the hose restrict the flow of adhesive inside the hose and can create potential problems during operations.

Pub. No. 107 917A

Temperature Controller Manual 46-69 Page l-3

7. In drafty areas with the applicator guns unshielded from the draft. Rapid heat dissipation due to air movement across the guns may cause operational problems.

8. (If a handgun is used) with the handgun trigger left unlocked while the gun is unattended.

in addition:

1. Use only the metal base when attempting to lift or move an applicator. DO NOT use equipment covers, doors, panels or hose connectors as braces or grips.

2. NEVER use Nordson equipment as a ladder or stepping stool.

3. Route all hoses to prevent damage from kinking, abrasion and other physical damage. DO NOT allow a hose to be installed with a bend radius of less than 6 inches (150 mm).

4. NEVER point an applicator handgun at yourself or anyone else.

SAFETY DURING SERVICING

1.

2.

3.

4.

5.

6.

DO NOT perform internal service or adjustment on any equipment unless another person capable of rendering first aid and resuscitation is present.

Only qualified personnel should service Nordson equipment.

To avoid personal injury, never touch exposed connections and components while power is ON. Dangerous voltages exist at several points in the equipment.

Disconnect, lock out and tag external electrical power before removing protective panels or replacing electrical components.

Remove all jewelry (rings, watches, etc.) before servicing equipment.

If possible, stand on a rubber mat when servicing Nordson equipment. DO NOT work on equipment if standing water is present. Avoid working in a high-humidity atmosphere. Cover exposed terminals and work areas with rubber sheeting to avoid accidental contact while the Dower is ON.

Manua146-69 Page1-4


7. Always wear safety glasses, protective gloves (Nordson P/N 902 514) or equivalent and long-sleeved protective clothing to prevent injury from hot applicator parts, splashed hot melt adhesive and hot gun surfaces.

8. To prevent serious injury from molten adhesive under pressure, always relieve system hydraulic pressure (by triggering the gun, for example) before opening any hydraulic fitting or connection.

9. NEVER use an open torch, drill or broach when cleaning a noz- zle.

10. NEVER operate equipment with a known leak in the system.

SAFETY WHEN USING HOT MELT ADHESIVES AND SOLVENTS

Hot Melt Adhesives

1. Use extreme care when working with molten material. They solidify rapidly at high temperatures and present a hazard. Severe burns can occur if the molten materials come in contact with the skin. Even when first solidified, they are still hot.

2. Always wear protective clothing and eye protection when han- dling molten material or working near equipment containing hot melt adhesives under pressure.

3. IF MOLTEN MATERIAL COMES IN CONTACT WITH THE SKIN.

l DO NOT try to remove molten material from the skin.

l Immediately immerse the affected area in cold, clean water. Keep the affected areas immersed until the material has cooled. DO NOT try to remove the cooled material from the skin.

l Cover the affected area with a clean, wet compress.

l In cases of severe burns, look for signs of shock. If shock is suspected, have patient lie down, use a blanket to preserve body heat and elevate the feet several inches.

l Call a physician immediately.

Temperature Controller Manual 46-69 Page l-5

Heat Solvents

1. DO NOT use an open flame or uncontrolled heating device to heat solvents (for example, a small pan on an unregulated hot plate).

2. Avoid fire hazard by using a controlled heating device to heat solvents (for example, a small deep fat fryer or thermo- statically controlled hot plate).

3. DO NOT USE PAINT-TYPE SOLVENTS UNDER ANY CIR- CUMSTANCES! These solvents are volatile and may be a fire and/or toxic-vapor hazard even at room temperature.

4. Always be sure the work area is adequately ventilated. Avoid prolonged or repeated breathing of solvent vapors.

5. Halogenated Hydrocarbon Solvents are dangerous when used to clean aluminum components in a pressurized fluid system. No available stabilizers prevent halogenated hydrocarbon solvents from reacting under all conditions with aluminum components in a pressurized fluid pumping system.

6. NEVER clean any aluminum component or flush any system using halogenated hydrocarbon solvents. Use Type R (P/N 270 755) solvents or contact your solvent or hot melt supplier for a non-halogenated hydrocarbon solvent for cleaning and flush- ing. Halogenated fluids include the following solvents:

SECTION 4 OPERATING INSTRUCTIONS

DESCRIPTION OF OPERATION

The Single Channel Temperature Controller maintains the integral air heater’s temperature at the desired level by controlling the integral air heater’s power supply. A Resistance Temperature Detector (RTD) installed in the integral air heater provides feed- back to the temperature controller.

The white “power on” light on the front of the cabinet indicates when the unit is energized. The load light on the display panel indicates when power is being applied to the integral air heater. Under normal conditions, the load light will glow steadily while the air heater is warming up, and will then blink regularly as the controller maintains the air heater at the set temperature. The “Band” adjustment on the front panel is factory set and should not be changed.

NOTE: Any changes to the factory setting of the ‘Band” will seriously impair the temperature controllers performance.

SETTING THE REMOTE TEMPERATURE CONTROLLER

1. Turn the incoming power main circuit breaker ON. (Figure 4-l)

2. Turn the temperature controller rocker switch ON. The white light on the front panel will come on.

3. Push in and hold the control knob on the front of the controller. The digital readout will be the set point for the integral air heater. Turn the knob clockwise to increase and counterclock- wise to decrease the set point.

4. Release the control knob. When the knob is released the ac- tual temperature of the air heater is indicated.
