Automatic Electric Control Panel

Continuous change occurs through shift changes, operator rotation and load pattern progression. However, the system must start, transfer and stop without waiting for the operator’s intervention. We make Automatic Electric Control Panels intended for this type of use where electrical safety works together with sequence control. Each panel is designed specifically using the actual field input, the necessary response time, and an analysis of failure priorities, to ensure that the logic works correctly when the system is actually in use (not only during trials).

Our panels operate with either a PLC or dedicated control relays depending on the complexity of the process. Incoming power is constantly monitored for conditions of low voltage, phase loss and overcurrent protection. Output feeders for electric motors, electric heaters, electric pumps or utility loads are interlocked with permissive signals so the wrong sequence of operation will never occur. The panel has provisions for both automatic and manual selection with the needed electrical isolation necessary to perform maintenance on the panel.

The door-mounted status indicators indicate operation commands and healthy state, trip status and hold conditions. The internal wiring is grouped according to the function, which makes it easier when troubleshooting shutdown issues. The control supply is independent of the power supply so that the automation can maintain stability even if the power supply experiences transient disturbances.

Testing includes simulations of power failures, sensor failures, overload trips, and automatic restart sequences. After commissioning the panel will control ALL of the electrical devices in a predetermined logic flow, decreasing the operator's reliance on timing and increasing the overall efficiency of the plant with respect to changes in load conditions, as well as providing a uniform response to fault conditions within the plant.
