INSTALLING THE AMH-38 AUTOMATED MASS HANDLER
To install the AMH-38 mass handler on the PG7601 Platform, first install the mass set (see
Section 6.5.2). Then proceed as follows (see Figure 50).
Insert the mass lifting shaft into the AMH : With the AMH-38 sitting on a flat surface
and with all pneumatic and electrical connections in place, insert the mass lifting shaft
into the hole in the center of the AMH mass lifter and slide it down until the trim mass tray
sits on the top of the lifter. This arrangement trips the AMH’s internal proximity sensor
allowing the AMH system to be operated off of the PG7000 Platform without an actual
mass load.
Clear the AMH and test its operation : On the PG7000 Terminal, press [SPECIAL] ,
<8AMH> , <2control> , <3loadall> . The trim mass tray should rise approximately 2.5 cm
(1 in.) above the top of the lifter. Then the trim mass tray should be lowered back down.
The steps of this procedure are commented on the PG Terminal display as they occur. If
the sequence does not complete and/or any error messages are observed, see the AMH
Operation and Maintenance Manual for troubleshooting assistance. If the sequence
completes, the mass handler has been cleared and put into a known state in which all
mass holding ledges and pins are retracted so that it can safely be slipped down over the
mass set and installed on the PG7000 Platform (see Figure 50).
