6. POWER SUPPLY PCB The Power Supply PCB receives 230VAC power from the Electronic box This voltage can be measured using a Digital Volt Meter at J1 pins 1 and 2 on the Power Supply PCB The AC power passes through board bridge rectifiers converting the power to 9VDC which is used to power all of the 4 Scanner Motors This 9VDC can be measured at J2 pins 1 2 and 3 Pins 4 5 and 6 are ground connections This voltage must be adjusted after the installation of the Power Supply PCB Follow the procedure below to measure and adjust the output voltage to the scanner motors 1 Remove the weight tray 2 Place the positive lead of the Digital Volt Meter on Pin 1 Red wire and the negative lead of the Digital Volt Meter on Pin 6 Black wire 3 Use a small pocket screwdriver and adjust the pot to obtain a voltage reading between 9 9 5 VDC Adjustment Pot Pin 6 Pin 1 Effective Page 5 6 10 2006 OPTIMA POWER CLAMP ASSEMBLY The BFH Optima series balancer is equipped with a power clamp that eliminates the need for a standard or quick clamp nut The Power Clamp is activated by lifting up on the foot pedal mounted on the balancer The vibratory system has an optical sensor mounted on the shaft that senses variation on a visible encoder disk The opti switch looks to see if the shaft is spinning before operating the power clamp The power clamp will not open or close if the shaft is spinning The large pulley drives the power
