READ THE FOLLOWING PARAGRAPHS BEFORE PROCEEDING TO ''TEST PROCEDURE''.
{THIS PROCEDURE IS ONLY TO BE PERFORMED BY AUTHORIZED PERSONNEL)
CAUTION:
Loads controlled by Bypass/Isolation Transfer Switch may cause PER
SONAL INJURY by UNAUTHORIZED PERSONNEL operating or testing
this equipment.
Check all wiring diagrams that have been supplied for added options that
may affect external equipment: For example; Starting and Stopping of
Elevators and Motors.
A 'Control Panel Test' or a test with the ATS in the TEST LOCATION runs
the EMERGENCY SOURCE with no load. A no load operation may be
detrimental to the engine, and the Engine/Generator Manufacturer should
be consulted.
Allow sufficient time on the U timer for engine to safely cool down.
RECOMMENDED TIMER SETTINGS:
T -
Restoration to Normal .............. 30 minutes (Factory set)
U -
Engine Cooldown/Stop ..............
5
minutes (Factory set)
W -
Engine Warmup .................... 1 second (Factory set)
P1 - Engine Start. .....................
3
seconds (Factory set)
TEST PROCEDURE
The A TS can be tested in either of two locations:
1 ).
AUTO LOCATION
2). TEST LOCTION
1).
"AUTO LOCATION":
Full Transfer Test -
This test checks the complete operation of the ATS by transferring
and interrupting the load's power source from 'Normal' to 'Emergency'.
Depress TS (Test Switch) until Generator starts and the 'W' timer times out (timer will indicate ON).
ATS will transfer to Emergency.
Release TS (this resets TS to AUTO). Normal restoration timer
'T'
will time out (will indicate ON)
which will energize the CR relay causing ATS to retransfer back to Normal.
Engine/Generator will shut down after timer U times out. Full Transfer Test is now complete.
2).
"TEST LOCATION":
This procedure is recommended for Preventive Maintenance (PM) of ATS without interrupting the
Load thru the BYPASS/ISOLATION SWITCH. Refer to Page 8 (Step 3).
NOTE: TEST LOCATION is recommended after maintenance of ATS.
