Title: Timers won't turn off
Post by: Carolyn on December 16, 2003, 07:19:54 AM

I'm trying to use a timer to increment a sequencer.  Basically, I have step 2 of Sequencer 6 energize a 5 second timer.  Once the timer is on, it will set Sequencer 6 to step 3, at which point the timer should turn off because power is no longer at step 2 of the sequencer.  In the simulation, however, the timer coil stays on and will not turn off.  Does anyone have a possible explanation for this?  I have a screen shot of the circuits, but I couldn't figure out how to post that here.  Thanks!

Try moving the rung that contains the timer coil to the further down the ladder rung from the sequencer. The reason is explained in Page A 1-3 of the Internet TRiLOGI Programmer's reference under the topics "3. Timer Contact Updating Process".

If this does not resolve your problem, your can email your program to support@tri-plc.com with explanation note on the problem area and we will examine your program and identify the problem in your codes.
