12 Ronk Vigilant®Owner’s and Installation Manual
INSTALLATION AND WIRING
Power Connections
Proper power cables need to be installed to the transfer switch
and should be installed by licensed electrical contractors.
Improper installation or connections of these power cables are
extremely dangerous and may cause severe injury or death. All
power connections are to be connected to the proper lugs, which
are included on the switch contactor and neutral block assembly.
Connect the utility, generator, neutral and load cables to the
terminals, which are clearly marked on the transfer switch (see
Figure 5). Verify that all connections are correct before tightening
lugs. All power cable lug connections must be tightened to the
proper torque values as shown in Table 1 and Table 2.
!
WARNING
Low-voltage wire cannot be installed in the same
conduit as power voltage wiring. It could result
in shock due to short circuit as well as cause
electromagnetic interference resulting in
non-operation of the system.

requires a reference to neutral for AC sensing, which it obtains
from the distribution system via Battery -.
RSC1 and RSC2 need to be connected to the remote start/stop
connections of the generator to allow automatic starting. These
are N.O. dry contacts.
An optional customer-supplied test switch may be installed by the
customer using the TEST 1 and TEST 2 terminals. A closed circuit
between the test connections will simulate a utility failure. See
wiring diagram for details.
The battery charger needs to be of high quality. Low-quality
battery chargers will often go into full recharge mode due to VTS2
controller current draw. This will quickly wear out the battery.
14 Ronk Vigilant®Owner’s and Installation Manual
GENERAL OPERATION
Vigilant®Series General Operation
The Vigilant®switch in combination with the control board timing
module will allow for the automatic transfer of an electrical
load to a standby power source in the event of an over/under
voltage or frequency condition on any or all phases of the utility
power supply.
In the event of an over/under voltage or frequency condition of
utility power, the onboard control board sensing circuitry will
begin the initiation of the transfer process. Upon initial sensing of
a loss of utility power, the Vigilant®transfer switch is specifically
designed to allow an engine start time delay period (TDES) to
expire before starting the generator. This engine start time delay
is user-adjustable from the VTSC100, preventing unnecessary
engine starts from a temporary loss of utility. In the event the
utility source is not restored after the engine start time delay has
expired, the remote contacts will close, sending a signal to the
generator’s automatic start controller.
When the control board senses that the generator has started,
and is within acceptable limits, the transfer switch will wait until
the utility to generator time delay (TDNE) has expired before
switching to the generator position. All connected loads will be
transferred to the generator power source.
While the transfer switch is in the generato position, the control
board will constantly monitor the utility source voltage and
frequency status. Once the utility source is restored, the transfer
switch will wait until the generator to utility time delay (TDEN) has
expired before switching back to the utility position. All connected
loads are transferred to the utility power source.
When connected loads are transferred back to the utility power
source, an engine cooldown period (TDEC) will be initiated,
allowing the generator to run in a no-load condition. This engine
cooldown time delay is user-adjustable from the control board,
allowing the generator to continue running for an adjustable
period after the utility is restored.

TDEC Time Delay Engine Cool: This delay allows the engine to continue running after the transfer switch returns to the normal (utility) position. When
the control board recognizes that the transfer switch is in the normal (utility) position after an emergency generator) to normal (utility) transfer, the
generator will continue to run under a no-load condition until the engine cool time delay has expired.
TDES Time Delay Engine Start: This delay prevents unnecessary engine starts. When the control board determines a utility failure, it will wait for the
Engine start time delay to expire before trying to start the generator
TDNE Time Delay Normal (utility) to Emergency (Generator): This delay allows the generator to stabilize before any load is transferred. This normal
(utility) to emergency (generator) time delay allows the generator to be fully running before supplying power to a load.
TDEN Time Delay Emergency (Generator) to Normal (utility): This delay allows the utility source to be monitored for stability. This emergency (generator)

Controller test switch
Test
Utility/Normal
Manual testing of the Vigilant®transfer switches may be achieved
by manual adjustment of the test switch located on the control
board. The controller test switch will allow manual testing of the
transfer switch. The purpose of the test switch is to simulate a
utility power failure. Normally the test switch would be set to the
utility position, allowing proper sensing for normal utility faults.
To simulate a utility fault when no fault actually exists, the test
switch would be set to the test position, allowing the transfer
switch to transfer to the generator position. After testing, utility
power can be restored simply by setting the test switch back to
the utility position.
Remote test switch
The remote test switch will allow remote testing of the transfer
switch. The purpose of the test switch is to simulate a utility
power failure. The remote test switch may be installed by a
licensed electrical contractor; the switch would be installed at
the TEST 1 and TEST 2 on the terminal block. Normally the test
switch would be set to the DISABLE position, allowing proper
sensing for normal utility faults. To simulate a utility fault when
no fault actually exists, the test switch would be set to the
ENABLE position, allowing the transfer switch to transfer to the
generator position. A SPST test switch rated at a minimum of 1A
should be used.
Exerciser
The purpose of the exerciser is to perform a test of the transfer
switch either manually or automatically. The exerciser may be
adjusted by a licensed electrical contractor to any specific time
or day in which to perform a test. The exerciser can perform a
test for a load or no-load condition. For details instructions on
operational and setting instructions, see ENGINE EXERCISER
AND EXTERNAL LED ANNUNCIATION on page 22.

MANUAL TRANSFER
Manual Transfer of Mechanism
!
WARNING
Never perform a manual transfer while the
transfer switch is under load. Manual transfer is
not recommended. If performing an emergency
manual transfer, be certain to isolate the transfer
switch from all power and load sources.
Manual transferring is not recommended. If the transfer switch
fails to transfer in an emergency, an optional manual transfer
may be performed. Caution must be taken to confirm that the
transfer switch is isolated from all possible load sources before
transferring. Please note the flat side of the removable handle
must face away from the power connection side of the switch
mechanism as seen in Figure 12 for easy transferring. Always
remove the handle from the manual transfer handle lever location
after each transfer.
100A/200A Manual Transfer
In 100 and 200A transfer switches, the manual transfer lever
located on the contactor is used to manually transfer between the
utility and generator position. With the lever facing up toward the
normal side, the switch will be in the normal position. With the
lever down facing toward the emergency side, the switch will be in
the emergency position.
!
WARNING
Never allow the removable lever handle to come
in contact with live wires or terminals.

mechanical damage.
Inspect the transfer switch for loose hardware Check all hardware including controller, exerciser, terminals, etc. for any looseness due to
vibrations, etc.
Check for any overheating due to loose connections Check for any discoloration, melting or blistering of wiring or connections.
Perform regular testing of the transfer switch Perform regular testing of the switch to check for proper operation in case of emergency.
Maintenance
Always maintain a 3 feet (92 cm) clearance around the Vigilant®
transfer switch. Once a month, visually inspect the outside of the
switch for accumulation of dirt, moisture and/or corrosion on the
enclosure.
The homeowner or end user is responsible for following all
maintenance and periodic testing procedures and guidelines of the
generator owner’s manual to ensure proper operation.
