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. | 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.

The motor should be mounted to a 1/4 to 3/8 inch aluminum plate when possible to serve as a heat sink. The plate can then be spaced out from the frame with threaded rod for positioning toward the reaction plate. | |||
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. | 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. | ||

The motor control circuit needs some motion feedback from the bell to determine that it is swinging properly. We offer two types of feedback devices to accomplish this. The wiring requirements are the same for both. Four conductors of a telco or CAT5 cable usually suffice for this low current 12V signaling. | The motor control circuit needs some motion feedback from the bell to determine that it is swinging properly.

=== | === Precision rotary motion sensor (standard) === | ||
This option is used with a MagForce motor improved motion feedback. The rotary encoder is mounted to a non-moving part (like an A-stand) with pulleys and belt to sense the precise angular movement of the swinging bell axle. A separate logic translator is supplied in a weatherproof box and may be used as a junction box at the bell location. | |||
There are four wires used in the encoder cable that connect to the translator: | |||
Green to quadrature input '''A''' on the translator | |||
Gray to quadrature input '''B''' on the translator | |||
Brown to input '''+V''' on the translator (+5VDC) | |||
White to input '''0V''' on the translator | |||
The translator outputs connect one to one to the motion controller sensor inputs: '''P''' (pulse), '''D''' (direction), '''+''' (positive power, +12VDC), '''-''' (negative power). | |||
For rotary encoder systems, verify that the label on the CPU chip of the motor control system says "SENSOR." Use the '''[[IntelliSwing_Rotary_installation#Programming_the_controller|rotary motor programming procedure]]''' and set the Transmission value to 22.8. | |||
=== Proximity sensor === | |||
These sensors are not used in recent installations. | |||
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. | A three wire (60 inch cable) proximity sensor provides output when a bolt head or metal flag is about 1/4 inch away.

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. | 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: | Three wires are required for each bell's motor to the MagForce control box.

If the motor is sized to require an overload protector, the ''L1'' connection to the triac input will be routed in a serpentine fashion through the three overload circuits.

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. | The right cursor button will take you through the settings for each bell in the system.
