ASPMETER

INSTALLATION GUIDE

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 userdened 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.

4. To determine an address, simply add the values of any switch that is on.

For example:

LSB

Switch number 4 has an ON Value of 8 and switch number 6 has an ON Value of 32.

(8 + 32 = 40). Therefore, the address for the ASPMETER is 40.

See the Address Setup section (page 8) for a pictorial listing of the rst 63 switch positions.

DEFAULT DIP SWITCH SETTINGS

The ASPMETER includes two DIP switches, as shown below. Switches are shown in their default positions.

2. Address Conguration: Each Modbus device on a single network must have a unique address. Set the switch block to assign a unique address before the device is connected to the Modbus RS-485 network. If an address is selected which conicts with another device, neither device will be able to communicate.

INSTALLATION GUIDE

SAFETY

If ASPMETER products are used in installations with circuits higher than the product ratings, the circuits must be kept segregated per UL508A Sec. 17.5.

Note: 277/480 VAC Wye connected (center grounded) power systems operate within the 300 VAC line to neutral safety rating of the ASPMETER series, and the operational voltage limit (single-phase connection) as the line to neutral voltage is 277 VAC in such power systems. Corner-grounded delta 480 VAC systems would not qualif y, as the actual line to earth voltage is 480 VAC on each leg, exceeding the ASPMETER ratings.

Note: ASPMETER internal circuitr y (cables and CTs) are not circuits as dened by UL508A, as they do not extend beyond the ASPMETER itself without further safety/re isolation.

UL listed under standard 508 as an “open type device.”

Maximum ambient air temperature for use is 60°C.

Installation categor y: CAT III

The ASPMETER Series must be installed in an appropriate electrical and re enclosure per local regulations.

9. Connect 2-wire 90-277 VAC power to main power terminals. Observe polarity. For the ASPMETERA and ASPMETERB, connec t voltage lines to the voltage taps (Figure

8). Equip voltage lines with fuses.

ASPMETER

• Check the unit Modbus address to ensure that each device on the daisy chain has a unique address.

• Check Parity.

• Check the communications wiring.

• Check that the daisy chain is properly terminated.

• Check for reversed polarity on Modbus comms.

• Check for sucient biasing on the Modbus bus. Modbus physical specication calls for 450-650Ohm biasing.

This is usually provided by the master.

• Check that the 1A and 1B CT strips are connected to the left top and left bottom ribbon cable connections; 2A and 2B must be connected to the right top and right bottom ribbon cable connections (see illustrations in the product install).

• Verify ribbon cable connectors are inserted in the correct orientation.

• If cables are correct, reset main board to re-initialize product.

• Verify serial number on strips matches serial number on main board.

• One or more channels is clipping, this can be caused by a signal greater than 100 A or 277 V L-N, or by a signal

with high THD near the gain stage switching points (1.5 A and 10 A).

• Everything is wired properly and the main board has power.

• Light may be red briey while device powers up.

• If light is red for more the 60 sec. device has encountered an error. Contact technical support.

• Verify voltage taps are connected in appropriate phase rotation.

• Verify strip conguration register matches actual strip installation.

• Verify phase rotation of breakers (rmware rev. 1.012 or higher allows for custom rotation if needed).

• Verify strip conguration register matches actual strip installation.

• Verify ribbon cable is fully seated and in the correct orientation.

• The product cuts o at 50 mA, and will set the reporting register to 0 mA for currents near or below this range.

• Verify using the latest release of E3x Cong Tool as older versions may not support all features in current product
