TP-6807 12/11 26 Section 5 Scheduled Maintenance
Servicing the transfer switch. Hazardous voltage can
cause severe injury or death.
Deenergize all power sources
before servicing. Turn off the main circuit breakers of all
transfer switch power sources and disable all generator sets
as follows:
(1) Move all generator set master controller
switches to the OFF position. (2) Disconnect power to all
battery chargers. (3) Disconnect all battery cables, negative
(--) leads first.
Reconnect negative (--) leads last when
reconnecting the battery cables after servicing. Follow these
precautions to prevent the starting of generator sets by an
automatic transfer switch, remote start/stop switch, or engine
start command from a remote computer. Before servicing any
components inside the enclosure: (1) Remove all jewelry. (2)
Stand on a dry, approved electrically insulated mat. (3) Test
circuits with a voltmeter to verify that they are deenergized.
Short circuits. Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage . Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
NOTICE
Hardware damage. The transfer switch may use both
American Standard and metric hardware. Use the correct size
tools to prevent rounding of the bolt heads and nuts.
NOTICE
Electrostatic discharge damage. Electrostatic discharge
(ESD) damages electronic circuit boards. Prevent
electrostatic discharge damage by wearing an approved
grounding wrist strap when handling electronic circuit boards
or integrated circuits. An approved grounding wrist strap
provides a high resistance (about 1 megohm),
not a direct
short , to ground .
Screws and nuts are available in different hardness
ratings.
To indicate hardness, American Standard
hardware uses a series of markings and metric
hardware uses a numeric system. Check the markings
on the bolt heads and nuts for identification.
5.2 Testing
5.2.1 Weekly Generator Set Exercise
Use the exerciser or a manual test to start and run the
generator set under load once a week to maximize the
reliability of the emergency power system.
5.2.2 Monthly Automatic Control
System Test
Test the transfer switch’s automatic control system
monthly. Refer to the RDC2/DC2 controller operation
manual for the test procedure.
D
Verify that the expected sequence of operations
occurs as the switch transfers the load to the
emergency source when a preferred source failure
occurs or is simulated.
D
Watch and listen for signs of excessive noise or
vibration during operation.
D
After the switch transfers the load to the standby
source, end the test and verify that the expected
sequence of operations occurs as the transfer switch
retransfers to the preferred source.
5.3 Inspection and Service
Contact an authorized distributor/dealer to inspect and
service the transfer switch annually and also when any
wear, damage, deterioration, or malfunction of the
transfer switch or its components is evident or
suspected.
5.3.1 General Inspection
External Inspection. Keep the transfer switch clean
and in good condition by performing a weekly general
external inspection of the transfer switch. Check for any
condition of vibration, leakage, excessive temperature,
contamination, or deterioration. Remove accumulations
of dirt, dust, and other contaminants from the transfer
switch’s external components or enclosure with a
vacuum cleaner or by wiping with a dry cloth or brush.
Note: Do not use compressed air to clean the transfer
switch because it can cause debris to lodge in the
components and damage the switch.
Tighten loose external hardware. Replace worn, missing,
or broken external components with manufacturer-
recommended
replacement parts. Contact an
authorized distributor/dealer for specific part
information and ordering.
Internal Inspection. Disconnect all power sources,
open the transfer switch enclosure door, and inspect
internal components monthly or when any condition
noticed during an external inspection may have affected
internal components.
Contact an authorized distributor/dealer to inspect and
service the transfer switch if any of the following
conditions are found inside the transfer switch.
D
Accumulations of dirt, dust, moisture, or other
contaminants.
D
Signs of corrosion.
D
Worn, missing, or broken components.
D
Loose hardware.
D
Wire or cable insulation deterioration, cuts, or
abrasion.
