Settings Menu (3/7) - VigiPacT RHU User Guide

Overview

The Settings menu displays the setting parameters.

The Settings screen allows to set the following parameters:

I alarm: Alarm threshold
t alarm: Alarm time delay
I pre-alarm: Pre-alarm threshold
t pre-alarm: Pre-alarm delay
Alarm reset: Manual or Automatic

A password must be entered in the settings menu to modify the parameters.

Select the parameter to set and press to display the parameter screen.

Functional Parameter Settings

Parameter	Description
Alarm threshold	Where, XX displays the alarm threshold setting value in mA/A. Factory setting: 30 mA Minimum value: 30 mA Maximum value: 30 A Setting step: 1 mA from 30 mA to 999 mA and 0.1 A from 1 A to 30 A. NOTE: After the validation of the new alarm threshold value: The pre-alarm threshold value is set by 50% of the new alarm threshold value.
Alarm time delay	Where, XX displays the alarm time delay setting value in seconds. Factory setting: 0 s Minimum value: 0 s Maximum value: 4.5 s Setting step: 0.01 s NOTE: The values between 0 s and 60 ms are prohibited (the setting values are: 0, 60, 70..., 4500 ms). When I alarm is 30 mA, t alarm is locked at 0 seconds. Under this circumstance, if you try to modify the t alarm, /!\ I alarm = 30mA is displayed in the third line.
Pre-alarm threshold	Where, XX displays the pre-alarm threshold setting value in mA/A. Factory setting: 15 mA Minimum value: 15 mA Maximum value: 30 A Setting step: 1 mA from 15 mA to 999 mA and 0.1 A from 1 A to 30 A. NOTE: The pre-alarm threshold value is locked and cannot be increased further if it is increased up to the alarm threshold value. The pre-alarm threshold value is locked and cannot be decreased further if it is decreased up to 20% of the alarm threshold value. When there is a new alarm threshold, the pre-alarm threshold value is set to 50% of the new alarm threshold value.
Pre-alarm time delay	Where, XX displays the alarm time delay setting value in seconds. Factory setting: 0.2 s Minimum value: 0 s Maximum value: 4.5 s Setting step: 0.01 s NOTE: The values between 0 and 60 ms are prohibited (the setting values are: 0, 60, 70 to 4500 ms).The pre-alarm time delay will be set to alarm time delay value automatically if the pre-alarm time delay is above the alarm time delay when the alarm threshold and pre-alarm threshold are equal.

Alarm Reset Mode

The Alarm reset screen allows to select the alarm reset mode as Manual or Automatic.

The alarm reset can be configured through the HMI and Modbus (only for VigiPacT RHU relay).

If the alarm reset mode is Automatic, then the alarm is reset automatically.

If the alarm reset mode is Manual, you can reset the alarm manually through one of the following options:

by pressing on the relay
by using a Reset button wired to the Reset input of the relay
by sending a reset command through Modbus communication (only for VigiPacT RHU relay)

NOTE: Depending on the selection of Manual or Automatic mode, the VigiPacT RHU/RHUs relay is considered as protection relay (Manual mode) or a monitoring relay (Automatic mode).
