MagForce motor system installation: Difference between revisions

[http://www.chimemaster.com/swinging-motors Chime Master intelliSwing MagForce™] swinging bell systems feature a unique touch-less, friction-less and nearly silent motor technology. A stationary drive module induces electro-motive eddy-current forces into a reactor plate mounted to the free swinging bell assembly. A wall mounted motion control panel intelligently experiments and quickly learns the unique physical properties of your bell then carefully manages the energy required for accurate ringing.  

Motors can be mounted above the bell (at the same radius from the pivot point) if the weight of the reaction plate is taken into consideration when designing the head stock crank depth. This will also slow the ringing tempo. Do not mount the motors above the pivot on existing cranked head stocks, the bell will not ring properly.  

The motor induction housing should be painted with a polyurethane coating for UV resistance when used outside, and can be painted with the tower to match.

=== Mounting the reaction plate ===

Securely fasten the reaction plate to the wheel when possible, centered on the stationary motor brick. There should be about a quarter-inch gap between them and the mounting design should be rigid enough that you cannot pull them together by hand. During operation, the plate will be magnetically attracted to the motor, and the rigidity is required for sufficient swinging torque.

A three wire (60 inch cable) proximity sensor provides output when a bolt head or metal flag is about 1/4 inch away. Typically, a bolt is mounted to protrude from the bell wheel or head stock assembly. A stainless steel sheet metal flag is also supplied that can be mounted with dual adhesive foam tape or epoxy to the wheel or head stock.  

If you use a cable with other colors to extend these wires, make note of the colors you splice together, so the connections to the control computer circuit board are correct.

Three wires are required for each bell's motor to the MagForce control box. A cable (18 inch long) is permanently attached to the motor with seven wires (1-6 and ground). They are connected in the bell motor junction box as follows:

=== Using the Terminal ===

The right cursor button will take you through the settings for each bell in the system. From the status window, shown below, you can cursor left to select another bell. To change settings you can increment/decrement using the up and down arrow buttons, or input the value with the numeric buttons and save it with the EXE button.

For proximity (period) sensor systems, set the transmission value to 5.0. In order to calibrate the angle of the bell to the swinging period, set the Oscillation value as follows:

* Go to the 1Oscillation screen. The default value at the top of the display is 900. The bottom of the display should read "Stop" and "180" (if not set yet)

* Have someone move the bell by hand so that the proximity sensor begins to blink. At this point the number beside "Stop" should begin to change and there should be a blinking asterisk to the right of "Stop."  

** If this does not happen, check the sensor connections. If the light on the sensor is on when the flag is near it, and off when the flag moves away, the sensor has power (through the + and - wires), but the output signal is not getting to the D input on the control board.

* Swing the bell by hand (or by use the '''EXE''' key to electrically pulse the motor if you can not reach the bell) to a little more than 20 degrees. The bottom number will begin to change first, indicating what the controller estimates the maximum angle of the bell to be based on the fixed period on the top line.

** After five consecutively similar swings, the swing period at the top of the screen should change from the default value of 900 to the actual swinging period of the bell (in milliseconds).

* After the bell has coasted to about 20 degrees, watch for the period to update then press the '''ON''' key to save it current period. The display will say ''Stop'' and the top period will remain static. The bottom right number will indicate the approximated angle that the bell is swinging.

=== Select Swing Angle and other parameters ===

Make a record of the following settings for future reference when setup is complete:
