1.3 Product Overview
The RTC-100 controller is a comprehensive, multi-function, micropro-
cessor-based ATS controller. Designed to meet the needs of mar-
kets worldwide, the RTC-100 controller:
•
Is a UL Listed Component
•
Complies with UL 1008/ CSA 22.2-178
•
Complies with UL 991 humidity tests
•
Complies with IEC 61000-4-2, 61000-4-3, 61000-4-4, 61000-4-5,
61000-4-6, 61000-4-11, 61000-3-2, and 61000-3-3
•
Complies with CISPR 11, Class B
•
Complies with FCC Part 15, Class B
•
Meets European Standards Conformance (CE mark)
The RTC-100 controller provides an unmatched degree of pro-
grammed flexibility to address the needs of any system. It operates
on 240 VAC, single-phase at 50 or 60 Hz. The RTC-100 controller
monitors the condition of the line voltage of both the Utility and
Generator power sources. The RTC-100 controller provides the nec-
essary intelligence to insure that the transfer switch operates prop-
erly through a series of programmed sensing and timing functions.
A standard RTC-100 controller will:
•
Monitor Utility and Generator power source voltages
•
Provide undervoltage protection of the Utility and Generator
power sources
•
Permit easy customer set-up
•
Provide source status indications
•
Monitor and actively control two loads to ensure that the genera-
tor does not become overload by those loads.
•
Actively control, with external RLC-100 load control boards, an
infinite number of loads to ensure that overloading of the genera-
tor does not occur
•
Provide start signals for all makes and models of generators
(Utility sensing, 2 wire start, etc.)
1.4 Glossary
With respect to their use within this document and as they relate to
transfer switch and controller operation, the following terminology is
defined.
Available
A source is defined as “available” when it is within its undervoltage
setpoint range.
Connected
Connected is defined as when the input is shorted by an external
contact or connection.
Failed or Fails
A source is defined as “failed” when it is outside of the applicable
voltage ranges for the nominal voltage and for a time exceeding
0.5 seconds after the time delay emergency fail (TDEF) time delays
expires.
Failsafe
Failsafe is a feature that prevents disconnection from the only avail-
able power source and also forces a transfer or re-transfer operation
to the only available power source.
Re-Transfer
Re-transfer is defined as a change of the load connection from the
Generator to the Utility.
Utility
Utility is the primary source (normal source, normal power source, or
normal).
Generator
Generator is the secondary source (emergency source, emergency
power source, emergency, standby, or backup source).
Utility: Failed or Fails
Utility is defined as “failed” when it is outside of its undervoltage
setpoint range.
Generator: Failed or Fails
Generator is defined as “failed” when it is outside of its undervolt-
age setpoint range for a time exceeding 0.5 seconds after the TDEF
time delay expires.
Transfer
Transfer is defined as a change of the load connection from the
Utility to the Generator power source.
Unconnected
Unconnected is defined as when the input is not shorted by an
external contact or connection.
