A sump pump control system for monitoring and driving AC pumps that are supplied by directly either by AC utility power, or converted DC battery power. AC power is continuously monitored and the control automatically switches to DC battery supply in the case of power failure. DC battery power is converted to AC power. The control is equipped with unique pump switching circuitry allowing the pumps to be configured in parallel or staggered positions. Both pumps automatically alternate to prevent damage to pumps from humidity and corrosion that can result from remaining idle. Each pump has its own float switch to control operation. A third float switch controls both pumps in case of failure of either pump or float switch. Multiple visual and audio signals are included, displaying present power and pump conditions as well as alerting to any pump malfunction. The control utilizes two 12 volt deep cycle lead acid batteries that are being monitored for voltage level and continuously trickle charged to maintain maximum capacity. Batteries can be paralleled to obtain longer pump running time when AC power fails. The control system also allows for use of a single pump in the absence of a second pump.

A magnetic chuck control system employing solid state circuitry including a power output circuit adapted to apply a DC voltage to an object such as a magnetic chuck or the like so as to magnetize the same. The power output circuit employs a triac reversing circuit and is interfaced with a digital control circuit and a digital-to-analog converter circuit so as to apply alternating polarity voltage signals of successively reduced magnitude to the chuck during a demagnetizing operation. All high voltage is confined to the power output circuit so as to provide significant safety protection to the operator.

Prior art magnetic chuck control systems do not utilize state of the art components and do not sufficiently isolate the power output from control circuits. The instant invention discloses a magnetic chuck control system employing solid state circuitry including a power output circuit (24) adapted to apply a DC voltage to an object such as a magnetic chuck (12) or the like so as to magnetize the same. The power output circuit employs a triac reversing circuit and is interfaced with a digital control circuit (26) and a digital-to-analog converter circuit (30) so as to apply alternating polarity voltage signals of successively reduced magnitude to the chuck during a demagnetizing operation. All high voltage is confined to the power output circuit so as to provide significant safety protection to the operator. Various control functions such as full power, variable power, residual power and release have digital interlocking so that an operator must effect full power or variable power after a residual power function.
