Breaker trip unit that limits mean power by switching loads and counts voltage quality events.

The ABB Emax 2 with Ekip Touch trip unit is an air circuit breaker that can keep the mean power of a site under a limit by switching loads and can count voltage quality events. This Modbus RTU template reads the power limit, mean power, load status and the daily sag, swell and harmonic counters, and lets you set power limits, time windows and thresholds from ModbusCloud.

Protocol: Modbus RTU
Connection: RS485, 19200 baud
Registers: 414, read and write

Brand: ABB
Key readings: Actual power limit · Mean power · Shed loads · Load input status · Voltage sags and swells · Voltage unbalance · Harmonic distortion duration
Available commands: Power limits · Load priority and times · Weekly time windows · Power quality thresholds
Compatible models: Ekip Touch · Ekip Hi-Touch · Ekip G Touch · ABB SACE Emax 2 E1.2, E2.2, E4.2 and E6.2 with Ekip Com Modbus RTU, trip unit firmware 3.xx, with the Power Controller or Network Analyzer function

If a device is not in the library yet, we build the template for free as soon as we have the register data.

Use cases

Show mean power against the active power limit on a dashboard for the main distribution board.
Get an alarm when the number of shed loads rises above zero during opening hours.
Keep a year of daily voltage sag and swell counts to discuss supply quality with the grid operator.
Raise a lower power limit for a weekend from ModbusCloud without a site visit.
Alert on a load alarm flag so the technician knows which feeder failed to switch.

Installation

Fit the Ekip Com Modbus RTU module in the Emax 2 terminal box and give the trip unit and module auxiliary supply.
Wire the RS485 pair of the module to RS485 A and B of the ModbusCloud Gateway and terminate the bus with 120 ohm at both ends.
Check on the Ekip Touch display that the power controller or network analyzer function is present, and note address, baud rate and parity (default 247, 19200, even).
In ModbusCloud, add a Modbus device with the same settings, or use the device of the core Emax 2 template, and import this template.
Check that mean power and the actual power limit come in and match the trip unit display.

Things to watch for

All power controller values stay at zero. Why?

The power controller and network analyzer are optional functions of the trip unit. If they are not installed or not enabled, the parameters read as zero. Check the function list on the Ekip Touch display and the enable flag of the power controller.

The module does not answer at all. What should I check?

Check the auxiliary supply of the Ekip Com module and that address, baud rate and parity match the Gateway (default 247, 19200, even). Swap A and B if needed and terminate the bus at both ends.

Why do the scheduling and configuration values look like odd numbers?

Several settings pack more than one field into one value, such as the start and end hour of a time window or the priority and type of a load. Split the value into its bits or bytes to read each field.

Can I change power limits from ModbusCloud?

Power limits, load parameters and thresholds are writable, but the trip unit only accepts new settings inside a programming session, which you start and end with commands in the core Emax 2 template. Write one value at a time, check it on the display, and agree changes with whoever is responsible for the switchboard.
