optiview panel

[heavymetaldad]

stopped in on 1 of mine - (2) yt design 'j' electro-mechanical starters.both run remote by bas. machine online purring like a kitten.
the other machine off - ready to start - in the box where fault is listed - motor pulldown limit. THE MACHINE WAS OFF!!. won't reset on the panel toggle, had to de-energize & reboot to reset. didn't show in the history section,(but why would it). i have a tinge saying this will reappear again, probably limiting the machine on a day when the sh@t hits the fan with the dog days rapidly approaching
any comments? :confused:

What happens when you switch or run machine in local mode in optiview panel

Was the panel in "remote" or "ISN"?

machine room is run remotely. when the message was seen - machine was off line, ready to start. thanks for response

Let me re-phrase. Are they talking to a microgateway or just a contact closure?

i'm sure it's not relay logic. they change setpoint from their room downstairs, they've had previous issues with the siemens automation. (phantom chiller starts w/ no a/h's in the wee hours.had multiple hi disch. temp. failures. siemens techie found the start command buried deep in his program.)
if bas would limit loading, would it be displayed w/ machine off? (ready to start?) why, then , did the message 'reset' (disappear) when rebooting? (the opti) but,you got me thinking, that this may be an issue with the automation.
thanks for your reply

I should be easy to tell. If there is a 3x4 board mounted in the top left side of the Optiview, it has a microgateway. Whether they are using it or not,you would have to check. Sounds like they are. Could be a communication problem between them.

If it is new, they could be using the "e-link"

believe it's a gateway. bldg. had field installed 2-3 yrs. ago, to tie in automation.
