Automatic Transfer Switch Owner’s Manual 9
Section 4: Operation
Functional Tests and Adjustments
Following transfer switch installation and interconnection,
inspect the entire installation carefully. A competent,
qualified electrician should inspect it. The installation
must comply strictly with all applicable codes, standards,
and regulations. When absolutely certain the installation
is proper and correct, complete a functional test of the
system.
IMPORTANT: Before proceeding with functional tests,
read and make sure all instructions and information in
this section is understood. Also read the information and
instructions of labels and decals affixed to the switch.
Note any options or accessories that might be installed
and review their operation.
Manual Operation
A manual handle is shipped with the transfer switch. See
1 in Figure 4-1. Manual operation must be checked
BEFORE the transfer switch is operated electrically. To
check manual operation, proceed as follows:
1. Ensure the generator is in the OFF mode.
2. Turn OFF or OPEN both UTLITY and
EMERGENCY power supplies to the transfer
switch, with whatever means provided (such as the
main line circuit breakers).
3. Note position of transfer mechanism main contacts
by observing display windows in “A” and “B” (3 and
4 in Figure 4-1) as follows:
• Window “A” ON, Window “B” OFF - LOAD termi-
nals (T1, T2, T3) are connected to utility terminals
(N1, N2, N3).
• Window “A” OFF, Window “B” ON - LOAD termi-
nals (T1, T2, T3) are connected to emergency ter-
minals (E1, E2, E3).
Close to Normal Source Side
Before proceeding, verify the position of the switch by
observing Window “A” in Figure 4-1. If Window “A” reads
“ON”, the contacts are closed in the normal position, no
further action is required. If it reads “OFF,” proceed as
follows:
1.
Attach handle to the actuating shaft (see 2 in Figure 4-
1
).
2. Move handle in the direction of the arrow on the
switch cover until it stops — DO NOT FORCE.
3. Release handle slowly to allow the spring in the
switch box to relax. “ON” now appears in Window
“A” and “OFF” appears in Window “B”.
Close to Standby Source Side
Before proceeding, verify the position of the switch by
observing Window “B” in Figure 4-1. If Window “B” reads
“ON”, the contacts are closed in the EMERGENCY
(STANDBY) position. No further action is required. If it
reads “OFF”, proceed as follows:
1.
Attach handle to the actuating shaft (see 2 in Figure 4-
1
).
2. Move the handle in the direction of the arrow on the
switch cover until it stops - DO NOT FORCE.
3. Release handle slowly to allow the spring in the
switch box to relax. “OFF” now appears in Window
“A” and “ON” appears in Window “B”.
Return to Normal Source Side
Manually actuate switch to return Window “A” to the “ON”
position.
