Transfer Switch with RTC-50 Control
SECTION 5: FUNCTIONAL TESTING
YOU ARE READY TO ENERGIZE THE EQUIPMENT. VOLTAGES
WITHIN THE ENCLOSURE ARE CAPABLE OF CAUSING SEVERE PER-
SONAL INJURY OR DEATH. USE EXTREME CAUTION TO AVOID
CONTACT WITH ENERGIZED EQUIPMENT.
5.1 Preliminary Checks
Step 1: Check all loads connected to the ATS to ensure that they
are ready to be energized.
5.2 Energize the Switch
Step 1: Using a voltmeter, measure the line-to-line and the line-to-
neutral voltages across the utility line terminals to ensure
the utility voltage is correct.
Step 2: Close the upstream utility power source breaker or switch
to connect the ATS to the utility power source voltage.
Step 3: If the ATS unit is not already in the UTILITY position, and
the voltage is acceptable, the solenoid will engage and
the contactor will automatically switch to the UTILITY
position.
CONTACT WITH ENERGIZED COMPONENTS WILL CAUSE ELECTRI-
CAL SHOCK CAPABLE OF PRODUCING 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 generator control selector switch, located on
the standby generator, to the AUTOSTART position. (It
may also be labeled REMOTE START or AUTO.)
5.3 Operational Checks
Step 1: Open the upstream utility breaker
originally closed in Step 2 of Section 5.2.
THIS WILL SIMULATE AN INTERRUPTION OF THE UTILITY POWER
SOURCE.
Step 2: After a time delay (based on the generator settings), the
standby generator engine will start.
Step 3: Using a voltmeter, measure the line-to-line and line-to-
neutral voltages across the generator line terminals to
ensure that the generator emergency voltage is correct.
If necessary, make adjustments to the voltage regulator
on the generator according to the manufacturer's recom-
mendations to correct any voltage deviations. The ATS
will only respond to the correct voltage from the genera-
tor power source.
Step 4: Close the upstream generator power source breaker or
switch to connect the ATS to the generator power supply
source.

Step 5: The ATS Time Delay Normal (Utility) to Emergency (Gen-
erator) (TDNE) will begin to time after the generator
engine begins to run. After time out, the solenoid will
engage and the contactor will automatically switch from
the UTILITY to the GENERATOR position.
Step 6: Close the utility breaker described in Step 1 of
Section 5.2.
Step 7: The ATS Time Delay Emergency (Generator) to Normal
(Utility) (TDEN) timer will begin timing, and the solenoid
will engage and automatically switch from the GENERA-
TOR to the UTILITY position and the generator will shut
down after a cool down period.

5.4 Manual Operation

DO NOT ATTEMPT TO MANUALLY OPERATE THE ATS WITH THE
UTILITY OR GENERATOR AVAILABLE.
HIGH VOLTAGES ARE PRESENT IN AND AROUND TRANSFER
SWITCH EQUIPMENT. BEFORE ATTEMPTING TO MANUALLY
TRANSFER, DISCONNECT THE LINE POWER FROM THE EQUIPMENT
BEING SERVICED BY OPENING AND LOCKING OUT, IF POSSIBLE,
THE NEXT HIGHEST DISCONNECT DEVICE. FAILURE TO FOLLOW
THIS PROCEDURE COULD CAUSE SEVERE PERSONAL INJURY AND/
OR DEATH.
ALWAYS TURN THE UTILITY POWER OFF AND TURN THE GENERA-
TOR (IF A GENERATOR) CONTROL SELECTOR SWITCH TO THE
"OFF" POSITION BEFORE ATTEMPTING A MANUAL TRANSFER.
INSURE THE DEADFRONT IS INSTALLED PRIOR TO ENERGIZING THE
TRANSFER SWITCH.
To manually operate:
1. Disconnect all sources of power.
2. Disconnect the J5 connector from the RTC-50 controller.
3. Locate the manual lever between the solenoids.
4. Locate the handle used to manually transfer the switch.
5. Attach the handle to the manual lever.
6. Move the lever to the left to go to Utility or move the lever
down (200 A), or to the right (100 A), to connect
to Generator.
7. Reconnect the power.
8. If automatic operation is required, disconnect all sources of
power, reinstall the J5 connector, and reconnect the power.
