How to clear and install I/O units and Arc sensors for the VAMP321 arc flash mitigation relay

Issue

How can the connected I/O units and arc sensors be cleared, reset, and reinstalled on a VAMP 321 arc flash mitigation relay?

Product

VAMP 321 Arc Flash Mitigation Relay

Environment

Relay configuration, arc protection setup, I/O units, and arc sensor installation.

Cause

The VAMP 321 may require the existing arc sensor and I/O unit configuration to be cleared and reinstalled when connected devices are added, replaced, removed, or need to be rediscovered by the relay.

Resolution

To clear the I/O units and arc sensors, press the Down Arrow until Arc is selected, then press OK. Scroll down to Clear, press the “i” button, and then press OK. When prompted for a password, enter the default edit password 2 and press OK. The relay will return to the Clear selection. Press OK, select Clear, and press OK again. This resets the arc sensors and I/O units configured on the VAMP 321. To reinstall the connected devices, scroll to Install, press OK, select Install, and press OK again. The relay will then reinstall the I/O units and arc sensors connected to the device.
