To help the organ builder identify rectifiers that are not adequately regulated Peterson includes a Power Supply Fault Detector on systems that we mount and wire This Fault Detector is otherwise optionally available The Fault Detector indicates out of range for high level and low level Voltages via latched LED indicators NOTE Organ indicators that flash and dim when pistons are pressed typically indicate an inadequate rectifier See Peterson s IMPORTANT PRECAUTIONS and ORGAN POWER SUPPLY AND FEEDWIRE SIZE WORKSHEET for more information We recommend replacing questionable older organ rectifiers with Peterson Inteli Power switch mode power supplies SAFETY PROCEDURES AND CAUTIONS 1 NEVER apply power to the system during installation All wiring must be completed and thoroughly checked Then follow the Initial Test procedure before applying any power 2 Organ rectifiers supply Voltages and currents similar to arc welders Due to these high currents it is highly recommended that the organ power be turned off whenever the system is being worked on 3 If it is necessary to work on the system while the power is on for your own personal safety we recommend removing jewelry such as watches rings or pendants before work is attempted Jewelry that shorts across the organ supply will heat up rapidly and may cause severe burns Electronic components can also be damaged 4 Do not lay tools wire solder hardware or any

A we highly recommend that the on and off coil wire cabling be bundled separately from the sense and piston wire cabling Do not run the wires of these two categories together since this has been found to occasionally cause problems under certain circumstances The sense contact is usually the same contact that is used to operate the relay or a stop action in the organ this is the simplest and preferred arrangement If this sense contact is connected to a magnet it is necessary that a flyback spark suppression diode be connected across the magnet to protect the combination action The polarity of the diode is important To determine polarity operate the magnet involved and measure the Voltage across it noting which is the positive end Always connect the cathode banded end of the diode to the positive end of the magnet Sense input protection circuit boards are available from Peterson These include flyback diodes for each sense input and plug onto the SBDS board s Flyback diodes for the on and off coils are built into the output of the SBDS boards Each stop magnet of each division should be assigned a number in some logical manner from left to right for example It would be a good idea to list the stop assignment on the form supplied Fig 3 For future reference Each position s on off and sense pins must all be connected to the same stop action magnet Stops can be contr
