Automation The unit is equipped with an electrical control panel. The process variables (pressure and level) are maintained by digital regulators or PLC control logic. Front panel controls/lights: main switch, emergency push-button, switch for local/remote system start with system in operation light, blocks reset button, power supply and alarms lights. Feed-back available (SPDT contacts): power supply, system in operation, alarm (cumulative). Digital input (stable contacts): external consent/alarm, remote system start.
