Click PLC Motor Warning Delay Time Example

Click PLC Motor Warning Delay Time Example Many times a warning delay timing circuit is used before starting any machine movement from motors or actuators. Looking at rung 3 of our ladder logic sample, if the start internal bit C1 is on and the 10-second timer has completed then the motor output is turned on. Rung 4 will control the red light output. If C1 is on and the timer is not finished the light will flash with the 1-second clock pulse. If C1 is off then the light is on. Rung 2 controls the on-delay timer. C1 will start the 10-second timer. The first rung has a pushbutton start (X1). This passes through the pushbutton stop (X2) to turn on C1. C1 is then used to latch itself so that the X1 condition does not matter. This is a common circuit in many applications. Programming and examples of the Click and Click PLUS PLC series can be found at this URL: https://accautomation.ca/series/click-plc/ https://accautomation.ca/click-plc-timers-and-counters/ There are several reasons why we are using the Click and Click PLUS PLCs. Here are just a few. - Investment is low for the hardware and the software is free - Standalone PLC with built-in I/O - Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc. - Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly.
