2. Safety instructions 2.1 General safety instructions Part of the device documentation in addition to this manual is the enclosed "Safety instructions for Bender products". 2.2 Work activities on electrical installations Only qualified personnel are permitted to carry out the work necessary to install, commission and run a device or system.
Safety instructions 2.3 Intended use The voltage monitor VME420 monitors AC/DC systems in the frequency range DC/15…460 Hz for undervoltage, overvoltage, underfrequency and overfre- quency. The devices are designed for the nominal voltage range = 0…300 V. Separate supply voltage U is required.
3. Function 3.1 Device features Undervoltage and overvoltage monitoring of AC/DC systems 0…300 V in the frequency range DC/15…460 Hz Preset function: Automatic response value setting for undervoltage and overvoltage, < U and > U as well as for underfrequency and over- frequency <...
3. When the conditions 1 and 2 are satisfied, you can connect the voltage monitor to the three-phase system to be monitored according to the wiring diagram (page 22). The following predefined response values will be set automatically: VME420 Preset Response Response...

3.7 Functional fault If there is an internal functional fault, all three LEDs flash. The display shows an error code (E01…E32). In such a case please contact the Bender Service. 3.8 Fault memory The fault memory can be activated, deactivated or can be set to continuous mode (con).
3.11 Password protection (on, OFF) With the password protection activated (on), settings are only possible after entering the correct password (0…999). If you cannot operate your device be- cause you cannot remember your password, please contact info@Bender- service.com. VME420_D00026_03_M_XXDE/04.2019...
Function 3.12 Factory setting FAC After activating the factory setting, all settings previously changed are reset to delivery status. In addition, the preset function allows automatic adaptation of the response values in relation to the nominal voltage U 3.13 Erasable history memory The first alarm value that occurs will be stored in this memory.
