to save pulse count after scan is completed you must push sel,par,0,sav the with the selector cover off the light should blink as it scans and will advance to the next floor you can check to see if your scan is saved by pressing sel,par,1,E par 2 ect there will be a clc fault if you have a ivalid table hope this helps

First, When you scan the Hoistway on a DMC-I. You need to start in the Pit. The switch NEEDS to be right at 1 1/2 below the lowest landing. then on INSPECTION move up the hoistway WITH-OUT STOPPING until you get to the top limit. It needs to be set at 1 1/2 inch above the top landing. Once the car has stopped and while loking at the selector board LEDS bump the car down until you see the LED on the selector blink now it will be ok to save you hoistway scan. This is way of setting you the hoistway on a DMC. Take it from me I spent plenty of time adjusting them. Good Luck

Thanks everyone for you're responses. the 1 1/2" above the top floor and below the bottom floor was the fix for it. appreciate it very much!

If make sure that the battery on the main board has been replaced, this needs to be done every two to three years.
