IC698CPE040-JP Fault Alarm System

IC698CPE040-JP a variety of electric valves, solenoid valves should be open failed to open, the closed failed to close in place, because the actuator did not act in accordance with the requirements of the PLC control, so that the system can not work properly, reducing the reliability of the system. To improve the reliability of the entire control system, we must improve the reliability of the input signal and the accuracy of the action of the actuator, otherwise the PLC should be able to detect the problem in a timely manner, with sound and light and other alarms to prompt the operator to troubleshoot as soon as possible, so that the system is safe, reliable, and work correctly.

IC698CPE040-JP in the design of the automatic control system we have designed a 3-level fault display alarm system, the first level is set up in the control site of the control cabinet panel, with the indicator lamps to indicate the normal operation of the equipment and the fault situation, when the equipment is running normally when the corresponding indicator is bright, when the equipment is running with a fault when the indicator lamp flashes at a frequency of 1Hz. In order to prevent damage to the indicator bulb can not correctly reflect the work of the equipment, specially set up a fault reset / light test button, the system runs at any time to continue to press the button for 3s, all the indicators should be fully lit!
