• Altistart ATS 48. The Altistart 48 soft start soft stop unit is a controller with 6 thyristors which is used for the torque controlled soft starting and stopping of three phase squirrel cage asynchronous motors. Drive performance functions:. Exclusive Altistart torque control (patented by Schneider Electric) Constant control of the torque supplied to the motor during acceleration and deceleration periods (significantly reducing pressure surges) Facility for adjusting the ramp and the starting torque Starter can be bypassed using a contactor at the end of the starting period whilst maintaining electronic protection Wide frequency tolerance for generator set power supplies Starter can be connected to the motor delta terminals in series with each winding. Machine and motor protection functions:. Built in motor thermal protection Processing of information from PTC thermal probes Monitoring of start time Motor preheating function Protection against underloads and overcurrents during continuous operation. Functions facilitating the integration of the unit into control systems:. 4 logic inputs, 2 logic inputs, 3 relay outputs and 1 analogue Plug in I/O connectors Function for configuring a second motor and easy to adapt settings Display of electrical values and load state
