OPERATION
The ASPMETER Series Branch Current Monitor is a device designed to measure the
current, voltage, and energy consumption of up to for 46 circuits (42 branch circuits, 1
3-phase main, and 1 neutral).
The ASPMETER consists of a data acquisition board and two 21-unit current sensor
strips, with four auxiliary inputs. The strips are mounted on each side of the panel
board along the termination points of each breaker. The conductor passes through
the appropriate current sensor before terminating at the breaker. Each strip transmits
the current data to the data acquisition board.
Data is transmitted using an RS-485 Modbus protocol. Each data acquisition board
requires one Modbus address for the set of two current sensors and four auxiliary
inputs. Data is updated roughly every two seconds. As a circuit approaches the user-
defined threshold, the ASPMETER activates the alarm indicators.
The ASPMETERA measures both current and power for the mains and branch circuits.
The ASPMETERB measures both current and power for the mains, and current only in
each circuit. The ASPMETERC measures current only for the mains and branch circuits.

1. 50-Pin Ribbon Cable Connectors (Data Acquisition Board): 18 inch (457
mm) ribbon cables are provided for easy connection of current sensor strips to this
point of the data acquisition board.
Note: Connect CT strips to the correct ribbon cable connectors for each panel.
The top connector is for Strip A, and the bottom conector is for Strip B.
2. Auxiliary Inputs: These 0.333 VAC inputs are used for monitoring the main
breaker or other high amperage source.
3. Control (Mains) Power Connection: Easy 2-wire 90-277 VAC 50/60 Hz
connection.
4. Control Power Fuse: 600 VAC, 500 mA time lag, factory-replaceable.
5. Alive LED: Red/green/amber LEDs. Blink codes are on page 3.
6. Voltage Taps: 1, 2, or 3 phase plus neutral connections. For voltage sensing and
power calculations (no voltage taps on the ASPMETERC).
7. Communications Address DIP Switches: Each Modbus device must have a
unique address. Switches are binary weighted. Left-most switch has a value of 1;
right-most switch has a value of 128.
8. Communications Settings DIP Switch: Configures baud rate, parity, 2/4 wire
communications.
9. RS-485 2 Connection: Used for Modbus serial communications. The Universal
plug accomodates 2 or 4 wire connections.
10. RS-485 LEDs: The RX LED (closest to DIP switches) indicates the RS-485
is receiving information; the TX LED (farthest from DIP switches) indicates
transmission of information.
11. Power LED: Indicates power to main board
12. Current Sensors: Each current sensor is capable of monitoring conductors rated
up to a maximum of 100 amps.
13. 50 Pin Ribbon Cable Connectors (Current Sensor Strips): Connects current
signal from the sensor strip to the main board via the ribbon connectors.
