Removing the Limiter (ET Analyzers).
1.One of the limiters is secured by a plastic clamp. The clamp has two arms that snap
open and closed. To open the clamp, pull up on the end of the arm on top.
2.When removing a limiter from cabling, first loosen the nut that is captured on the
limiter and disconnect that end of the limiter.
CAUTION When applying significant torque to the nut, use a wrench or pliers to keep
the end of the semirigid cable from rotating.
a.If the limiter is connected to J6 via a semirigid cable (rather than directly
connected), remove the cable (see item 13 inTable 7-9on page7-13) before loosening
the nut on the other end of the limiter.
3.When loosening the nut on the other end of the limiter, use the 7/32-inch wrench to keep
the body of the limiter from rotating.
Installing the Limiter.
1.Reverse the procedure used to remove the limiter.
2.If the limiter is secured with a plastic clamp, first place the more narrow arm of the
clamp against the body of the limiter. Then press the second arm over the first arm
until its end snaps securely onto the first arm.
Installing the Receiver Assembly
CAUTION Be very careful when reconnecting the semirigid cables (items numbered 1
and 4 inTable7-2on page7-4) They are not interchangeable. Ensure that
one cable is not confused with the other. It is possible to force the wrong cable
onto the wrong connector, resulting in damage to the connectors/cables.
Tighten to 10 in-lb of torque.
1.Before inserting the receiver assembly into the chassis, be sure to inspect all cabling to
make sure it is below the level of the top of the couplers.
2.To install the receiver assembly into the analyzer, reverse the steps of the“Removing
the Receiver Assembly”on page3-13.
