Reference:
- Letter, D. L. Renberger to R.
H. Engelken, Same Subject, June 29, 1977.
Dear Mr. Engelken:
The reference letter stated that no ITE pneumatic time delay relays are used in safety related systems and that all pneumatic time delay relays used in safety related systems will have a repeat accuracy range smaller than
+ 15/.
We will continue to keep you advised should additional findings become known which modify our response for this or other IE Bulletins or IE Circulars.
s'i Continued follow-up to assure compliance and additional investigation by our Architect/Engineer revealed. that ITE Type J13P20 relays will be used in safety related systems.
These relays have been manufactured in 1974 and later, thus comply with IE Bulletin 77-01.
Very truly. yours, 4
ma/?~
