This
is the 2nd in our series of end of life/obsolete elevator control
systems. This one is a big one for
Colley Elevator, we installed hundreds of these elevator controllers in the mid
to late 1960’s and early to mid 1970’s.
Colley and ERM had a close relationship for many years and we still take
care of many ERM/Oliver Williams elevator controllers. For many years we have been letting the building owners know that they should consider replacement of these elevator controllers.
Who
this impacts
– This end of life/obsolete correspondence is for ERM/Oliver Williams
controller owners that have controllers from the mid 1970’s and before.

Mention
of SSD1 Drives
– We have had this letter since 2010 but we didn’t pay much attention to the
mention of the World Electronics SSD1 drive that is found on Virginia Controls,
US Elevators and other traction elevator controllers of this era. Our interpretation is that the SSD1 Drive
also called the GFC IIA drives are also at end of life and should be considered
obsolete. We have had more than a few run ins with these drives and once they
go, we have had a hard time resurrecting them to be safe and reliable service
with a repair. World Electronics does indicate on their website they repair the devices and supply new ones.
Take
away –
If you have any of these elevator controllers or drives you should be planning
for a elevator modernization. Talk to
your elevator contractor about reliability, safety and repair concerns you have. If you
have a 1975 ERM controller, that controller is now 45 years old and you now
have the end of life letter from the manufacturer. Get prices and get the equipment replacement
on the books.
