14) Return the transfer switch to utility power by re-closing the upstream utility
breaker. The load should re-transfer back to the utility supply and the engine
should stop as described in item #13 above.
15) Repeat tests #12 through 14 two (or more) times to ensure correct operation.
16) Automatic Plant Exercise Operation (OPTIONAL): If an automatic weekly plant
exercise feature is desired, press the GENERATOR EXERCISE Mode push
button on the TSC 80 faceplate. Hold the push button “ON” for approximately 5
seconds until the LED light changes state. Once the mode is initiated, the engine
will immediately start and the generator will transfer on load as previously
described. Note: The generator may or may not transfer on load, which is
dependent on the TSC 80 configuration setting. The factory default setting is for
a “Load Transfer” plant exercise test. The engine will remain operating on load
until the plant exercise time delay period expires, then the load will re-transfer
back to the utility supply following the 2-minute utility return timer. The engine will
be automatically re-tested on load every week (i.e.7 days) at the same time of day
that the first test was initiated. Refer to the TSC 80 manual for further
information.
17) On completion of commissioning ensure all controls are left in automatic.
18) If required, forward document or drawing updates to the equipment supplier if
revisions are required and provide the end user with a set of marked-ups to be
retained on site.
19) Ensure copies of manuals for the equipment are on site.
20) Record and forward list of deficiencies to the appropriate parties where applicable
