Does the PM550 have to be plugged into anything (other than AC power) for the red 'DC good' light to come on ? If so what pins on what connector need to be jumpered to verify 'dc good' ?
Thx all

TI PM550 power light
- Thread starter Capt_Davey
- Start date
I can't remember if the PM550 power supply has to have a load to get the light but.... there's a terminal block with contacts for it.Capt_Davey said:
They were used to do the same thing, if there was an issue with a bad power supply the contacts would let you know.
Can you just plug it in and check the state of the contacts?
I may have one around but there's no way to get to it today.
I'm amazed to find out that they are still out there!! I used to swap these units for newer PLCs quite some time back, especially on printing presses (Harris comes to mind) but the printing industry died about 7-8 years ago and everything is outsourced to China nowadays.

OK I tried the contacts but still no 'DC good'. I do not have the rest of the system to plug it into to test is why Im asking if its needed to activate 'DC good'. I found the 'smoking gun' problem (bad capacitor) but want to verify it is indeed fixed. Dont laugh but I have 4 of them I'm working on ..... LOL
Thx

If you do not have the rest of the system (CCU & I/O) the light will remain OFF.Capt_Davey said:
If the entire system is connected and in RUN Mode the DC Monitor light will be lit as long as there's no problem with the system.
I won't laugh!
I still have the manual for the hardware, the manual for the VPU200 and a Power Supply(PM550-210) plus the PLC (CCU) which is the high end one!!
16 Loops!!
Last I checked both the Power Supply and CCU were going strong.
Anyways, good luck.

DRATS ! I was fearfull of that 
Is there any way to jumper anything to see if the 550 will go active and show the 'DC good' light ?
PS: Thx for your help with this

Which Model Power Supply have you??Capt_Davey said:DRATS ! I was fearfull of that

PM550-210
PM550-212...
I can take a look in the manual and give you the pinout layout.
That will be a way to check for 24V, 9V, 5V etc.

2 Word docs attached here.Capt_Davey said:PM550-212 bkottaras Thx a million !
First shows the actual voltage on each pin.
The second one shows each pin and a description of potential (voltage).
Hope this helps a bit.
Let me know if you need the TCAM/LAM info, it is pretty straight forward though. +9V, Ground for each.
This connector is located below the DC LED.
Do you have a VPU by the way?
I can only borrow one from a local distributor and have had a hell of a time trying to Low-Format some of the "newer" 5.25" disks.
Let us know if you get it going!

Slightly off topic
I think we have a VPU in our instrument shop. I remember seeing it up on a shelf collecting dust. We upgraded our last 550 around '95 or so. I haven't opened the case, so the condition is unknown.
If some of you guys are interested, I could investigate, and see if everything is there.

is it the last generation VPU?
200 I think.
You can do pretty much everything with it on a PM550 system.
Just make sure when you transport, move the thing from place to place around the shop, a disk must be "parked" in the drive, otherwise the drive will get damaged instantly.
Haven't touched one in 4-5 years or so but it is nice to get to play with it when you do get a chance.
EDIT: Forgot to mention that you have to have the disk with the operating system in order for it to be fully functional.
I may have a disk or two around some place.
