 Caution

all possible ContingenCies that may arise during installation, 

operation, or maintenanCe, and all details and variations of 

this equipment do no purport to be Covered by these instruC-

tions.  if further information is desired by the purChaser 

regarding a partiCular installation, operation, or mainte-

nanCe of partiCular equipment, please ContaCt an authorized 

eaton eleCtriCal sales representative or the installing Con-

traCtor.

1.1 Preliminary Comments and Safety Precautions

This technical document is intended to cover all aspects associated 

with the installation, application, operation, and maintenance of the 

Automatic Transfer Switch Controller (RTC-100).  It is provided as a 

guide for authorized and qualified personnel only in the selection and 

application of the RTC-100 controller.  Please refer to the specific 

WARNING and CAUTION in Section 1.1.2 before proceeding.  If fur-

ther information is required by the purchaser regarding a particular 

installation, application, or maintenance activity, please contact an 

authorized Eaton Electrical Sales Representative or the installing 

contractor.

1.1.1 Warranty and Liability Information

No warranties, expressed or implied, including warranties of fitness 

for a particular purpose of merchantability, or warranties arising from 

course of dealing or usage of trade, are made regarding the informa-

tion, recommendations and descriptions contained herein.  In no 

event will Eaton be responsible to the purchaser or user in contract, 

in tort (including negligence), strict liability or otherwise for any spe-

cial, indirect, incidental or consequential damage or loss whatsoever, 

including but not limited to damage or loss of use of equipment, 

plant or power system, cost of capital, loss of power, additional 

expenses in the use of existing power facilities, or claims against 

the purchaser or user by its customers resulting from the use of the 

information and descriptions contained herein.

1.1.2 Safety Precautions

All safety codes, safety standards, and/or regulations must be 

strictly observed in the installation, operation, and maintenance of 

this device.

 warning

the warnings and Cautions inCluded as part of the 

proCedural steps in this doCument are for personnel safety 

and proteCtion of equipment from damage.  an eXample of a 

typiCal warning label heading is shown above to familiarize 

personnel with the style of presentation.  this will help to 

insure that personnel are alert to warnings, whiCh appear 

throughout the doCument.  in addition, warnings and 

Cautions are all upper Case and boldfaCe.

 warning

Completely read and understand the material presented in 

this doCument before attempting installation, operation, 

or appliCation of the equipment.  in addition, only qualified 

persons should be permitted to perform any worK assoCiated 

with this equipment.  any wiring instruCtions presented in 

this doCument must be followed preCisely.  failure to do so 

Could Cause permanent equipment damage.

1.2 General Information

Automatic Transfer Switches (ATS) are used to protect critical electri-

cal loads against loss of power.  The load’s Utility power source is 

backed up by an alternate power source such as a Generator.   An 

ATS is connected to both the Utility and Generator power sources 

and supplies the load with power from one of the two sources.  In 

the event that power is lost from Utility, the ATS transfers the load 

to the Generator power source.  Once Utility power is restored, the 

load is automatically transferred back to the Utility power source.
An intelligence system initiates the transfer when the Utility power 

fails or falls below a preset voltage.  An engine start is then initi-

ated by the Generator and the ATS transfers to the Generator power 

source when sufficient Generator voltage is available.  When the 

Utility power is restored, the ATS automatically transfers back to the 

Utility and the Generator will shut down after a time delay.  
ATSs automatically perform the transfer function, and include three 

basic elements:

1. Main contacts to connect and disconnect the load to and from the 

power sources.

2. Solenoids to make the transfer of the main contacts from source 

to source.

3. Intelligence/supervisory circuits to constantly monitor the condi-

tion of the power sources and thus provide the intelligence nec-

essary for the switch and related circuit operation.

This manual deals with the third basic element of the ATS, the 

required intelligence/supervisory circuits.  The RTC-100 controller 

advances the application of intelligence, supervisory, and program-

ming capabilities for ATS equipment.
