From ON to OFF, automatically when the lit-on cause disappears. In case of auxiliary power supply failure the status of the leds is recorded and reproduced when power supply is restored. Copyright 2010 - Microener Firmware: 1.0X... -
Page 7: Output Relays
Each relay is identified by its programmable address code (NodeAd) and can be called from the P.C. A dedicated communication software (MSCOM) for Windows 95/98 (or later) is available. Please refer to the MSCOM instruction manual for more information. Microelettrica Scientifica. Copyright 2010 - Microener Firmware: 1.0X... -
Page 8: Digital Inputs
Complete test activated by the keyboard or via the communication bus either with or without tripping of the output relays. If any internal fault is detected, the display shows a fault message, the Led "PROG/IRF" illuminates and the relay R5 is deenergized. Copyright 2010 - Microener Firmware: 1.0X... -
