1.6 Section V, Installation and Checkout
This section provides instructions for installing and checking your system to ensure correct
operation. The procedures are step-by-step instructions for assembling a system and are
divided
as
follows:
a. Preliminary checkout of individual units. For example, instructions are given on how to
check the laser transducer head and receiver prior to mounting them on your
equipment.
b. Physical installation of the laser transducer head, receiver, and optics. This procedure
references Section II, LASER TRANSDUCER AND OPTICS, and the layout measure-
ment paths you have prepared.
c. Recommended mounting and interconnection of electronics. Section V contains detailed
information to install and interconnect the system. Details of the cable connectors are
given in Appendix C. If the cables need to be fabricated, refer to Appendix E.
d.
A system checkout procedure, including some simple programs, to verify that your
system i s operating correctly.
e.
Any critical adjustments necessary to bring your system on-line (e.g., power supply
adjustments).
1.7 Section VI, Troubleshooting
This section tells you what to do when your system fails in order to return it to proper oper-
ation in the shortest possible time. The troubleshooting information is presented in the fol-
lowing manner:
a. A general discussion of how to troubleshoot and repair the Laser Transducer System.
b. Troubleshooting tips for rapid fault isolation. This will tell you how to quickly locate
a problem after your system has been operating.
A detailed troubleshooting procedure that is keyed to the system checkout procedure.
By structuring the troubleshooting procedure in this manner it i s possible to make
valid assumptions of equipment condition at different points in the checkout procedure.
For example, if the system controller has been checked and i s functioning properly,
it can be eliminated a s a source of trouble at that time. This approach allows the use
of the troubleshooting procedure during initial installation and checkout, and also if
a problem can not be located after the system has been operational. The latter is done
by disassembling your system and reperforming the installation and checkout proce-
dure. One caution about the use of any troubleshooting procedure is that somewhere,
sometime
a
trouble will occur that defies analysis by written procedures. At that time,
the only- solution is a knowledgeable, patient person tracking down the symptoms
until each has been corrected.
