I.B. ATS-RM05
Effective 6/01
5.3 OPERATIONAL CHECKS
Step 1: Open the upstream normal breaker originally
closed in Step 2 of Section 5.2.
This will simulate an interruption of the normal
power source.
Step 2: After a brief time delay of 10 seconds, the
standby engine generator will start.
Step 3: The ATS Time Delay Normal to Emergency
(TDNE) will begin to time after the engine
begins to run. After time out, the motorized
transfer mechanism will engage and automati-
cally switch from the NORMAL to EMER-
GENCY position.
Step 4: Using a voltmeter, measure line-to-line and
line-to-neutral voltages across the emergency
line terminals to ensure that the emergency
voltage is correct. If necessary, make adjust-
ments to the voltage regulator on the generator
according to the manufacturer’s recommenda-
tions to correct any voltage deviations. The
ATS will only respond to correct voltage from
the emergency source.
Step 5: Close the normal breaker described in Step 1.
Step 6: The ATS Time Delay Emergency to Normal
(TDEN) timer will begin timing, and the motor-
ized transfer mechanism will engage and auto-
matically switch from the EMERGENCY to
NORMAL position and the generator will shut
down.
SECTION 5: FUNCTIONAL TESTING
YOU ARE READY TO ENERGIZE THE EQUIPMENT.
VOLTAGES WITHIN THE ENCLOSURE ARE CAPA-
BLE OF CAUSING SEVERE PERSONAL INJURY OR
DEATH.
USE EXTREME CAUTION TO AVOID CONTACT
WITH ENERGIZED EQUIPMENT.
5.1 PRELIMINARY CHECKS
Step 1: Check all loads connected the ATS to ensure
that they are ready to be energized.
5.2 ENERGIZE THE SWITCH
Step 1: Close the upstream normal source breaker or
switch to connect the ATS to the normal source
voltage.
Step 2: If the ATS unit is not already in the NORMAL
position, the motorized transfer mechanism will
engage and automatically switch to the NOR-
MAL position.
Step 3: Using a voltmeter, measure line-to-line and
line-to-neutral voltages across the normal line
terminals to ensure normal voltage is correct.
CONTACT WITH ENERGIZED COMPONENTS WILL
CAUSE ELECTRICAL SHOCK CAPABLE OF PRO-
DUCING SEVERE PERSONAL INJURY OR DEATH.
USE EXTREME CAUTION TO AVOID CONTACT
WITH ENERGIZED COMPONENTS WHEN USING A
METER FOR VOLTAGE CHECKS.
Step 4: Position the engine control selector switch
located on the standby engine generator to the
AUTOSTART position. (It may also be labeled
REMOTE START.)
Step 5: Close the upstream emergency source breaker
or switch to connect the ATS to the emergency
supply source.
