![]() When the bottle is in position and 0.5 seconds have elapsed, the solenoid ( 032) will open the filling valve and remain ON until the photoeye (PE) detects a proper level. The feed motor M1 will be energized once the system starts ( M2 ON) it will stop when the limit switch detects a correct bottle position. Once the start push button is pushed, the outfeed motor ( output 031) will turn ON until the stop push button is pushed. Before using the ZEN, read this manual carefully so that you can use the ZEN correctly. Its development has drawn on OMRON's advanced control technology and expertise in manufacturing various types of controllers. ![]() Timer for 0.7 sec delay after level detectįigure 2 illustrates the PLC ladder implementation of the bottle-filling application. The ZEN is a compact and highly functional controller that can be used to easily automate small-scale applications. Wiring work is greatly reduced because separate wiring is not required for devices such as timers and counters. This single Unit easily provides relay, timer, counter, and time switch functions. Timer for 0.5 sec delay after position detect Saves Space, Wiring, and Installation Steps Versatile functionality in a compact body (70 mm wide × 90 mm high). Table 2 – Internal output assignment Device These assignments include the start and stop process signals. ![]() Table 1 shows the I/O address assignment, while Tables 2 and 3 present the internal and register assignments, respectively. ![]() The program will include start and stop circuits for the outfeed motor and the start of the process. Herewith you can do a lot of bigger scale automation whereas the 10 I/O versions are just to short of I/O’s. After the bottle is filled, the control program will wait 0.7 seconds before moving to the next bottle. ZEN-20C Programmable Relay Unit Omron With the ZEN-20 I/O you get in one unit 12 Inputs and 8 Outputs relays or transistor. ![]()
