Electric Company Water Heater User Manual

Installation & Operation 2-15MN1800
LMDS Series Dual Axis Linear Stepper Motor
Items Required but NOT
Included
1. A regulated 80 PSI air supply with a 5 micron filter for each motor.
A water separator is also required.
2. Two or four phase, 2 ampere (micro) stepper motor driver/controller for each motor.
Cleaning the Forcer and Platen
Prior to placing the Forcer on the Platen both surfaces must be cleaned.
Use this method:
1. Apply masking tape to lamination surface of the Forcer. Removing the tape
removes large particle contaminants.
2. Using alcohol, clean both surfaces to remove any adhesive residue and any
other contaminants on the Forcer and the Platen.
Note: Apply small amount of alcohol to cloth for cleaning. Never pour or drip alcohol
or other chemicals onto the forcer or platen surfaces.
3. Wax and polish Platen and Forcer surfaces. ( i.e. Turtle Wax ). Remove any
visible residue.
Cleaning the Air Bearings Required if the forcer is not lifting between 0.0005″ – 0.001″ ( i.e. rubbing on the Platen ).
1. Using a small screw driver, unscrew one air bearing.
2. Blow compressed air through the bearing in both directions.
3. Screw the air bearing back to its original position.
Note: Do not mix the air bearings, they have to be installed at their original position.
Installation: Mounting the Forcer on the Platen
1. Before placing the forcer on the platen be sure there is at least 60 psi of
regulated and filtered air flowing through the forcer.
2. Use the lifting tool (in reverse) to gently, place the forcer on the platen. Be
careful not to place your fingers between forcer and platen.
Removing the Forcer from the Platen
1. Before moving the forcer, be sure there is at least 60 psi of regulated air supply
with a 5 µm air filter flowing through the forcer.
2. Place lifting tool (provided) in slot on the side of the forcer. Gently, pry the
forcer from the platen with the tool. Lift the forcer and remove it from the
platen. Be careful not to place your fingers between forcer and platen.
Maintenance Waxing of the Forcer lamination for corrosion protection is recommended every month (or
as needed) depending on environmental conditions (i.e. humidity and moisture).
Operation Considerations The motor must always be operated within the specified operating parameter limits.
Exceeding those limits will permanently damage the motor.
The following steps must be completed to ensure safe and proper operation.
1. Verify that all electrical wiring and cables are properly connected. Refer to the
manual provided with the control for this information.
2. Adjust the stepper driver current to match the motor’s current specification.
3. Strain relieve the wires prior to operating.
