DESCRIPTION
The Series 2000 Load Banks are designed for electrically loading and testing power
sources. The Load Bank is designed for production line and job site use.
Refer to the schematic for the load bank KW (Current), voltage, phase and frequency
rating. Using the toggle switches on the control panel, any combination of the available
load steps may be selected to achieve a desired load.
The control panel is integrally mounted on the Load Bank. The controls/metering on the
control panel will vary depending on the model and available accessories. Refer to the
schematic for specific controls associated with the load bank provided. The general
arrangement for the control is:
MODELS 2100/2200
1. MASTER LOAD ON/OFF switch – Applies power to the Load Bank fans and allows
the instantaneous connection and disconnection of all switched ON load steps.
2. OVER TEMP/VOLT indicator – Indicates an air failure/insufficient cooling airflow or
an over voltage condition.
3. VOLTAGE SELECT switch – Configures load resistor circuit for dual voltage
applications if applicable.
4. LOAD STEP switches – Connect and disconnect load steps. Load values are shown
above each switch.
5. ANALOG/DIGITAL METERS – Displays Volts and Amps of Load Bank.
MODEL 2400
1. POWER ON/OFF switch – Applies power to the Load Bank and fan. The POWER
indicator lights when power is applied.
2. BLOWER FAILURE indicator – Indicates an air failure or insufficient cooling airflow.
3. MASTER LOAD ON/OFF switch - Allows instantaneous connection and
disconnection of all switched ON load steps.
4. LOAD STEP switches – Connect and disconnect load steps. Load values are shown
above each switch.
