I need to program a Square D Class 8003 MICRO-1 controller to time a kiln but I am running into a problem. I need to be able to run a bank of fans for 12 hours, stop wait a minute or so (to let the fans run down) and then run in the rev direction for 12 hours. The problem I am having is from my reading this PLC's timers can only be set to a max of 9.999 sec. That is not going to work for me. My Question, Is there a function or some other type of timer I am missing that can time 12 hours?

SQUARE D MICRO 1 PLC MANUAL. Additionally, it lets you split your recordings into tracks and helps you clean up your audio with effective sound cleaning filters. The international forum for control engineers, system integrators, and industrial automation professionals.

I am new to PLC's so this may be a dumb question but I am still at the level of asking dumb questions. Any help would be super great. Thanks in advance. Welcome to the forum! From what I understand the timers have a 100 millisecond or.1 sec timebase to a maximum of 999.9 seconds. I would set up a self resetting timer for 600 tenths or 60 seconds or 1 minute.

I would then use that timer output on another rung to trigger a counter with 720 counts (minutes) for a total of 12 hours. I would then use the counter output for whatever you want timed. Just curious, since it is a very old type, do you have the software and cable interface to program the plc? By the way, you can use WindLdr software by Idec to program this plc. Square D just private branded and re-labeled this plc, Idec was the parent manufacturer. If you have a copy of the current program on the plc, zip it and post it here. Maybe I or someone here can edit it and re-post it for you.

Sir thank you very much for your reply. Sorry I have not responded sooner but I was called out of town unexpectedly. As I said I am very new to PLC programing and have not been able to make a counter work with a timer to give me my needed 12 hours.

I dont have anything to upload as of yet. I have not got to that point yet.

What I need is very simple. I have only 1 input. That is just a power on line from the panel. All I need is 2 outputs. 1 for the forward run of 12 hours, a delay of 50 seconds to let the fans run down and 1 for the reverse run of 12 hours. Then a 50 second delay and start over. Any help would be of a BIG help.

Picture Publisher 9 more. Thanks again. I still think using the Idec software WindLDR is the way to go.

Having said that, here is a link to a manual that is for how the units were originally programmed with a hand-held Type PR-3 programmer. They were also programmed with SFW-30 Square D software.
