BOARD FUNCTIONS A general description of the Master Control Board operation only is included in the following The Master Control PC Board performs the following functions 1 Filtering and transient protection of the power supply KV and current feedback signals 2 Properly scaled and buffered output signals to the front panel digital displays 3 Conversion and buffering ofthe remote control input and output signals 4 Supplies the HV ON overload inhibit timer so that the system can initially charge to voltage without nuisance overloads An LED located on the board is active during the inhibit cycle 5 Compares the overload setting with the actual high voltage outputcurrent and generates a latched overload condition that results in high voltage shutdown A factory set potentiometer is located on the board that fine tunes the overload trip point This should only be adjusted by trained ITW Ransburg personnel or with instruction from ITW Ransburg or an ITWRansburg representative FRONT PANEL BOARD FUNCTIONS Refer to Figure 12 The front panel Door Board contains the local operator controls digital display interfaces dis play scaling adjustments factory set and the overload full scale range select switch A buff ered supply voltage is generated from 15VDC input for the displays ir Ransburg MOTOR CONTROL BOARD The LECU4013 00 Motor Control PC Board Assembly receives the 0 10VDC KV feedback sign
11. ELECTRICAL NOISE Electrical noise refers to stray electrical signals in the atmosphere at various signal strengths and frequencies that can affect the operation of equipment One of the best ways to prevent this is to shield the equipment and cables within a continuous ground envelope such that any incident noise will be conducted to earth ground before it can affect the circuit conductors For conductors inside the control panel and power supply tank the grounded enclosures provide this envelope A conductive gasket has been used on the control panel door to ensure a continuous ground envelope between the door and cabinet For the control cable that runs from the control panel to the power supply tank a shielded cable has been used The shield consists of an overall foil shield in combination with an overall braided shield This provides the most effective shielding as the foil covers the holes in the braid and the braid allows for practical 360 termination at both ends of the cable The AC input cord is not shielded but instead is directed to an AC line filter as soon as it enters the cabinet This filter filters out any noise that comes in onthe AC line For maximum noise immunity the AC line should connect to the filter as soon as it enters the cabinet with as short of leads as pos sible Additional noise protection is provided by running the AC input line to the control panel in grounded conduit which is the recommended
