APPLICATION DATA

4USE: This model provides a complete, self-contained system for the testing of generators, UPS's, & other sources of varying kilowatt
and voltage ratings. Typical users are generator set & electrical power equipment manufacturers. Other users are assemblers and
installers to provide performance verification of their equipment. This portable unit is easily transported and moved on-site to provide a
complete test system. This model also provides a complete, self-contained system providing the means of meeting NFPA 70, National
Electrical Code Standard, Article 700-4 for the exercising and operational support of a standby/emergency generator set. A load bank
sized for the "maximum anticipated load" of the facility will provide an optimum maintenance load in accordance with NFPA 70. It also
fulfills the exercising requirements of NFPA 99 & 100. Load bank use also prevents "wetstacking." Wetstacking is a condition that can
exist in diesel engines when all the fuel is not completely burned and passes into the exhaust system. In Diesel generators, wetstacking
usually occurs because the engine is running at only a small percentage of its capacity; therefore the engine does not achieve its optimum
operating temperature. Wetstacking may be detectable when there is a black oily residue exiting the exhaust, poor stability of the
generator, or when poor generator frequency occurs. Wetstacking can shorten the life expectancy of a diesel generator engine. Utilizing a
load bank to supplement the source load (or as the only test load) will help maintain the engine's optimum output rating and will eliminate
wetstacking (if the load bank is properly sized). Load banks may also be of necessity for the diesel engine's oxidation catalyst (soot trap)
system. Many air quality control districts require these emission reduction systems. In order for the oxidation catalyst system to function
properly, the engine exhaust must be maintained at a minimum output temperature. The exhaust temperature must be maintained at the
specific minimum level to regenerate the oxidation catalyst system to meet air quality standards.
4CONTROL: This load bank is controlled by an advanced dual processor embedded controller with integrated metering. The operator
controls the load bank via an intuitive LOADTEC® Digital TOUCHCOMMAND® Touchscreen O.I.P. (operator interface panel) Controller with
a monochromatic graphical LCD display for superior daylight operation. Upgrades to the latest control features can be achieved with a
simple firmware upload. Multiple Resistive and/or Reactive LOADTEC Load Banks equipped with the TOUCHCOMMAND®
Touchscreen controller can be networked together to create a larger system with a single-point, intuitive & intelligent
control*. The Touchscreen Controller requires only a single CAT 5 communication cable for connection and no additional
control power is needed if located within 250 feet of the load bank.
4CONSTRUCTION: This load bank is designed and constructed for a long and reliable life in industrial environments. This model is
constructed of galvanized steel that is primed & painted using UV Resistant Premium High Performance Acrylic Enamel. The enclosure
meets U.L. & Nema 3R outdoor weatherproof construction standards and is standardly provided with lifting eyes, forklift provisions,
stainless exterior hardware, and hinged access doors for connection & control compartments.
4RESISTAR® LOAD RESISTOR: The RESISTAR® is designed specifically for high-density applications. The resistor is continuously-
supported to minimize shorting contact with surrounding resistors. These resistors are terminated and supported with ceramic
components; no plastic or polyester glass laminates are used. They are then mounted in small trays that are easily removed in the field
and serviced by a single individual. The resistors are conservatively designed, therefore the RESISTAR® does not require a cool down
period and carries a standard; industry-exclusive, 3 year limited warranty.
4COOLING: This load bank is forced-air cooled by a direct drive airfoil propellers using (4) TEFC motors with disconnect and overload
relay. These motors contain sealed bearings that do not require lubrication or maintenance during the life of the motors.
4PROTECTIVE CIRCUITS: The load bank is protected with fusing for each load section and control circuit. It is also provided with an
airflow and temperature sensor to disconnect the load bank on a failure condition. Voltage and Frequency ranges are also monitored to
protect the control power circuits and during alarm exercise failures.
