RRS-4 Technical Manual 7/20/2011
1.0 Getting Started
The CBS ArcSafe® RRS-4 Remote Racking System is an upgraded version of the standard
RRS-1 Remote Racking System for rotary style breakers. The RRS-4 boasts many of the
same structural and mechanical components as the CBS ArcSafe® RRS-1 unit, which
make it the most portable, easily adjustable, and user friendly Remote Racking System
in the industry today. What makes the RRS-4 different from its RRS-1 counterpart, and
any other remote racking system on the market for that matter, is that it is operated
using a dual mode, source programmable, Programmable Logic Controller (PLC) based
control system.
This new PLC based control system offers two operating modes to choose from: CCM
Mode (drive motor current sensing mode) and SEK Mode (drive motor revolution
counting mode). Users are given the option of which control mode to choose upon
machine startup and can switch between the two during operation of different
switchgear.
CCM mode is a truly universal operating mode capable of racking virtually any rotary
style breaker and requires minimal setup. In SEK mode, users create a custom profile
for each breaker style being operated that includes real-time breaker location feedback.
Both modes are considered “Source Programmable”, meaning that all setup and
operation can be done in the field without factory assistance by following the setup
procedures detailed in this manual. Each of these two modes will be discussed in
greater detail later in this manual, for more specific operating information for each of
these modes please see the appropriate section of the manual.
The RRS-4 is powered utilizing an AC/DC power system, meaning that the unit can be
operated using standard 120VAC wall power or the internal batteries (which can provide
approximately 30-60 racking operations depending on the application) when wall power
is not available. The RRS-4 comes standard with both a corded 35’ pendant station
(extended lengths available) and a wireless radio remote pendant station capable of
operating the unit from over 100’ away.
