10'-50 ma output proportional controller. With the new bias board installed, the controller was reinstalled. The controller action was checked in MANUAL and AUTO modes and found to respond properly.
On ll/17/76 a poor cold soldered joint was found on a wire connected to the proportional band potentiometer. After resoldering this joint, the con-troller was bench tested for an hour before reinstalling. The controller action was checked in MANUALand AUTO modes and found to respond properly.
CAR 1108 was issued for this event.
