Dover LMH Information

Looking for information on Dover LMH controls. Any help is appreciated.

Is there something in particular that you want, or want to know.

I posted a different problem today with a fire service issue
2 stop unit, manual freight doors, main and alternate backwards.
I tried reprogramming them via the Omeron programmer. The main floor is the top(2nd) and alternate is the basement (1).
So per the book I have.
On the tool...
TRS,CNT,1,Read,2 enter :to set the main recall to 2nd floor

Then
TRS,CNT,2,Read,8 enter: to set the alternate floor.
Initially I used a 1 instead of the 8 here, but there is a note in the book saying on a two stop it has to be set at 7(top landing)
Either way the results were the same.
Car tries to recall to correct floor, stops at the floor then will run to the other floor. It continues to cycle like this. As far as I can tell I can view the IO info via the tool MON(add) function and they match what is on or off.
So, not sure if I am missing a step or might have a defective ee2 chip. It is an FA-2 junior unit with a 4k EE2 chip.module

Are you talking about lmh-plc?

I asked you some questions on the other post. The IDEC IZUNI Corp FA-2 is the programmer that I have used in the past. I am not familiar with the Omeron programmer, but as long as they change the counters correctly, it probably doesn't matter.

Count the pi outputs on the plc. You may only have 6 floors. TOP floor would need to reflect controller's configuration.

Counters take effect after power cycle. Good luck.

Which software makes a lot of difference with how to program. LMH Lite requires a top floor setting, others do not. What version of software do you have?

Here is what the book shows. For some reason there is a note about the two stop job counter being set at 8 instead of what would seem logical. Either way it doesn't work

Counter1 =8. main floor top
Counter2=1. alt floor bottom

Post a picture of the plc. Need software version and available I/os.

I believe those settings are for 8LIL software, but we don't know which software you have, so the settings may not be correct.

Thanks for the reply. I'll get by there and see if I can get the version. I have a spare E2module. I don't know what's still out here in terms of available programs.
