Page 3: Introduction
The MFC-400/I-VAC and MFC-400/I-VDC are precise, highly reliable and versatile mi- crocontrolled devices designed to read, display and retransmit AC or DC voltage values. Each MFC-400/I-VAC or I-VDC features one isolated RS-485 port, which can be used for communication using the MODBUS or DNP3 protocols. -

Licht http://www.licht-labs.com info@licht-labs.com 2 Front panel indication During operation, the MFC-400/I-VAC or I-VDC displays its voltage measurement. The presented value is equal to the measured voltage multiplied by the Sampling Factor para- meter. Figure 2.1 Front Panel Rev. A0 (20–05–09) MFC-400/I-VAC and I-VDC Technical Manual... -
Page 5: Configuration
3 Configuration Parameterization The MFC-400/I-VAC and MFC-400/I-VDC feature 4 keys to access their functions. The procedure to configure any parameter is as follows: 1. Press the P key to enter the parameters menu. 2. Enter the currently configured 4 letter password one letter at a time, using the keys to select each letter and P to advance between letters. -
Page 6: Programmable Parameters
4 Programmable parameters The MFC-400/I-VAC and MFC-400/I-VDC were developed to provide the user with the greatest possible flexiblity, such that all supervision and configuration can be executed on-site or remotely through the existing communication channels. We define all user-configurable parameters below. -
