Automatic Functions
In addition to remote monitoring and control, the GSC3000 and VRC2500 provide automatic control with
macros, actions and timed events. Macros are instructions for automated activities, which can include corrective
action in response to out-of-tolerance equipment, or complex routines such as a start-up procedures, power
trims, generator activation, etc. Actions runs when a channel has exceeded a limit and can issue commands, take
captures, or run a macro. Timed events initiate activities based on a schedule specified by you. Timed events may
be used to issue single commands, run macros or save site data for logging.
Data Collection & Automatic Logging
The GSC3000 and VRC2500 can store site data in onboard memory in the form of captures. Captures are
“snapshots” of instantaneous I/O unit conditions that are stored by the I/O unit, downloaded by Lynx, and
retained in the database for viewing and logging. Captures include metering values, status conditions, channel
muting status, and the current command state for each channel. When Lynx downloads these captures from the
I/O unit, the data they contain can be used for your site logs. Captures can also be set up to coincide with out-
of-tolerance channel conditions to provide operators with a complete summary of the unit data at the time the
condition occurred. Chapter 7 explains captures in more detail.
Logging is set up in the Site Wizard when you initially create your site in Lynx (see Chapter 2). Lynx can log site
data in two ways, and they can be used simultaneously or independently. The first method is to log site data
directly to Lynx (the software connects to your site and saves site data directly to your computer), and the other
is to download I/O unit captures (you set up captures to occur as timed events, and Lynx connects and
downloads the capture data). Direct logging is the simplest and most efficient way to log your site data.
Once you have logged data from your site, you can open the Report Writer (see chapter 9) to create and print
customized site reports. Data from captures, along with logging data, can also be viewed using the Capture
Browser and Data Browser, respectively (see pages 62 and 67).
Command Relays and Wiring Interfaces
Separate Command Relays and Wiring Interfaces provide a straightforward interface between your facility
equipment and the main unit. The Command Relay also provides isolation between the unit’s solid-state open-
collector outputs and your connected equipment.
POWER SUPPLY & SURGE PROTECTION
The power supply in the GSC3000 and the VRC2500 accepts an AC voltage input range of 100-240 VAC,
50/60 Hz. No modifications are needed for 120V or 240V operation. Power spikes and brownouts within this
range have no effect on unit operation.
Note: For additional specifications, see Appendix B.
Battery Backup
Both the GSC3000 and VRC2500 use an internal battery to retain configuration settings during a power outage.
Nonetheless, we strongly recommend connecting your GSC3000 or VRC2500 to a UPS battery backup system
so that it can remain powered long enough to start a generator or take other steps which you have programmed
to occur during a power loss. This will also allow the GSC3000 or VRC2500 to continue providing dial-out
alarm notifications. When choosing a UPS, make sure it provides enough power to operate
all GSC3000 I/O and
Voice Interface Units, or VRC2500s, at your site. Power output specifications for the I/O, Voice Interface, and
VRC2500 can be found in Appendix B.
