Troubleshooting Energy Reduction Maintenance Settings (ERMS)

Unable to engage ERMS using the ERMS switch.

Loss/insufficient power applied to the Micrologic X control unit via the circuit breaker's ULP port.

If the ERMS is in the disengaged (OFF) state (ERMS LED located on the the control unit is not illuminated) and the ERMS switch is set to the engaged (ON) state the control unit will remain in the disengaged (OFF) state.  This is the case if the control unit is being powered by only USB port, Voltage Power Supply (VPS), and/or by current passing through the circuit breaker.

Check power supply connections and voltage level applied to the Micrologic X control unit.

Loss of communication between ESM module and Micrologic X control unit.

If the ERMS is in the disengaged (OFF) state (ERMS LED located on the the control unit is not illuminated) and the ERMS switch is set to the engaged (ON) state, the control unit will remain in the disengaged (OFF) state.   An alarm will display on the Micrologic X control unit indicating that there has been a loss of communication with the ESM module.

Check to see if there is an alarm displayed on the Micrologic X control unit's HMI screen.

ESM module is not declared in the Micrologic X control unit.

—

Use EcoStruxure Power Commission PC app to declare the presence of the ESM module.

Incorrect connections to the ESM module and/or ERMS switch.

—

Check connections to ESM module and ERMS switch.

Unable to engage ERMS using the EcoStruxure Power Device app.

ERMS Digital module is not installed.

—

Purchase and/or install ERMS digital module.

ERMS unintentionally switches to the engaged (ON) state.

Loss of external signal source to the input of the ESM module.

—

Verify connections to the ESM module and to the ERMS switch.

Input signal source voltage is too low.

—

Verify that the signal voltage at the input to the ESM module connections is sufficient.

Unable to modify ERMS protection settings.

ERMS function is in the engaged (ON) state.

ERMS protection settings can not be modified while the Micrologic X control unit is in the engaged (ON) state

Disengage (set to OFF) ERMS function and then make changes to the ERMS protection settings.

ERMS Digital module is not installed.

ERMS digital module should be factory installed for circuit breakers ordered with ESM module.

Purchase and/or install ERMS digital module.

Unable to disengage ERMS using ERMS switch.

Loss/insufficient power applied to the Micrologic X control unit via the circuit breaker's ULP port.

If the ERMS is in the engaged (ON) state (ERMS LED located on the the control unit is  illuminated) and the ERMS switch is set to the disengaged (OFF) state the control unit will remain in the engaged (ON) state.  This is the case if the control unit is being powered only by the  USB port, Voltage Power Supply (VPS), and/or by current passing through the circuit breaker.

Check power supply connections and voltage level applied to the Micrologic X control unit.

Loss of communication between ESM module and Micrologic X control unit.

"If the ERMS is in the engaged (ON) state (ERMS LED located on the the control unit is  illuminated) and the ERMS switch is set to the disengaged (OFF) state, the control unit will remain in the engaged (ON) state.   An alarm will display on the Micrologic X control unit indicating that there has been a loss of communication with the ESM module."

Check to see if there is an alarm displayed on the Micrologic X control unit's HMI screen.

ESM module is not declared in the Micrologic X control unit.

If the ESM module is not declared in the Micrologic X control unit while the ERSMS function is in the engaged (ON) state, the ERMS cannot be disengaged through the ERMS switch.

Declare ESM module using EcoStruxure Power Commission PC app.

ERMS is still engaged through the EcoStruxure Power Device App.

To disengage (set to OFF) the ERMS function, all methods used to engage (ON) the ERMS function (ERMS swtich and/or EcoStruxure Power Device App) need to be set to the disengaged (OFF) state.

Disengage the ERMS function through EcoStruxure Power Device App.

Unable to disengage (set to OFF) ERMS using EcoStruxure Power Device.

ERMS is still engaged (ON) through the ERMS switch.

To disengage (set to OFF) the ERMS function, all methods used to engaged (ON)  the ERMS function (ERMS swtich and/or EcoStruxure Power Device App) need to be set to the disengaged (OFF) state.

Disengage the ERMS function through the ERMS switch.
