DMC Door Issue

Getting a 313 & 317 door fault on a DMC. Only getting 4V on my 5VDC on the door board, so only get 2V on my phase outputs instead of 2.5V. Have a PY2 door board. Any suggestions?

317 is your pulse cont is off and needs a relearn probably.
313 did reach door open limit.

have you checked the dol/dcl magnet holders are ok?

I don't know, I ain't a guru on this board specifically, but most processors like their voltage where it should be. 4v is very low for the 5v supply.

What is your 5vdc at in the cop?

There’s a capacitor in the door operator I’ve seen those cause weird problems.

my moneies is on the power supply in the COP. There starting to get that age.

We recently modernized 3 DMC’s. Best decision ever. Those darn operator are a pain, constantly recycling and minor adjustments that are very time consuming. Alpha controller with wittur LD 16 drive only retrofit. Haven’t had a single call in months.

Alto101 :
Did you get the LD 16 thru vertical express or Wittur direct?

We have had issue in the past and sent the door operator board for refurbishing to our local drive/board repairs vendor. what ever they did, fixed the issues.

Vertical express. Great concept. Really like the corded inspection station and magnetic corded light. We removed the alpha inspection station and wired in the VE components. A lot of extra stuff comes in the kit that was not used. This kit retains the original clutch and hallside hardware. Creativity with the mounting which we enjoyed fabrication with all the brackets provided.
DMC starting to be troublesome are such a headache. Usually the door operator and COP. Constant relearning of the door. Not to mention expensive software is needed to do this.
