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 overfrequency. The devices are de- signed for the nominal voltage range U = 0…300 V.
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 overfrequency < f and > f. •...
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 18). The following predefined response values will be set automatically: VME420 operating range Response value < U, < f Response value > U, > f 230 V 196…253 V...
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). If the fault memory is set to "con“...
With the password protection activated (on), settings are only possible after entering the cor- rect password (0…999). If you cannot operate your device because you cannot remember your password, please contact info@Bender-service.com. 3.12 Factory setting FAC After activating the factory setting, all settings previously changed are reset to delivery status.
Function 3.14 Alarm LEDs show which relay is in the alarm state When the menu item LEd is activated, the alarm LED AL1 indicates that K1 is in the alarm state. When AL2 lights up, K2 is in the alarm state. An alarm relay cannot switch to the alarm state unless an alarm category has been assigned to it.
Function 3.16 Frequency alarm in case of measuring voltage failure (Menu -> AL -> <U Hz) If the voltage of the monitored system falls to the point where the frequency can no longer be determined, this parameter is used to set how the frequency alarm should behave. On: The device sets the underfrequency/overfrequency alarm (factory setting).
Installation and connection 4. Installation and connection Only qualified personnel are permitted to carry out the work necessary to install, commission an d run a device or system. Risk of electrocution due to electric shock! Touching live parts of the system carries the risk of: •...

Installation and connection 1. DIN rail mounting: Snap the rear mounting clip of the device into place in such a way that a safe and tight fit is ensured. 2. Screw fixing: Use a tool to move the rear mounting clips (a second mounting clip is required, see ordering information) to a position that it projects beyond the enclosure.

5.3 Menu structure All adjustable parameters are listed in the columns menu item and adjustable parameters. A display-like representation is used to illustrate the parameters in the column menu item. Dif- ferent alarm categories can be assigned to the alarm relays K1, K2 via the submenus r1, r2. This is done by activation or deactivation of the respective function.
