2. Check that the system being monitored is operated with a nominal voltage of Un = 230 V and 50 Hz. This is the precondition for an auto-matic setting of the response values (Preset) after the first connection to the nominal voltage.

3. Make sure that the voltage monitor is in the delivery status (factory set-ting has not been changed). In case of doubt, restore the factory set-ting (page 34).

4. When the conditions 1 2 and 3 are satisfied, you can connect the volt-age monitor to the system to be monitored according to the wiring diagram (page 16). The following predefined response values will be set automatically:

The devices provide two separately adjustable measuring channels (overvoltage/undervoltage). When the measuring quantity exceeds the response value (Alarm 1) or falls below the response value (Alarm 2), the time of the response delays "ton 1/2" begins. After the expiry of the response delay, the alarm relays switch and the alarm LEDs light. If the measuring value exceeds or falls below the release value (response val-ue plus hysteresis) after the alarm relays have switched, the selected re-lease delay "toff" begins. After the expiry of "toff", the alarm relays switch back to their initial position. With the fault memory activated, the alarm relays remain in alarm state until the reset button R is pressed. Also in the event of complete power failure of the system being monitored, the delay times are effective during the energy backup discharging time.

3.2.1 Preset functionAfter connecting the system to be monitored for the first time, the re-sponse values for overvoltage and undervoltage (Alarm 1/2) are auto-matically set once to:Response value overvoltage ( > U): 1.1 Un Response value undervoltage ( < U): 0.85 UnResponse value overfrequency ( > f) at 1Response value overfrequency ( > f) at Response value underfrequency ( < f) atResponse value underfrequency ( < f) a

it is necessary to set the response values for Alarm 1 (AL1) and Alarm 2 (AL2) manually. A detailed description of the process is given in the chapter "parameter setting.After restoring the factory settings, the preset function is automatically active again.During operation, the preset function can be started manually via the menu SEt.

3.2.2 Automatic self testThe device automatically carries out a self test after connection to the system to be monitored and later every hour. During the self test inter-nal functional faults are detected and appear in form of an error code on the display. The alarm relays are not checked during this test.

3.2.3 Manual self testAfter pressing the internal test button for > 1.5 s, a self test is performed by the device. During this test, internal malfunction will be determined and appear in form of an error code on the display. The alarm relays are not checked during this test.While the test button T is pressed and hplay elements appear on the display.

3.2.7 Time delays t, ton and toffThe times t, ton and toff described below delay the output of alarms via LEDs and relays.

3.2.8 Starting delay tAfter connection to the voltage Un to be monitored, the alarm indication is delayed by the preset time t (0...300 s).

3.2.9 Response delay tonWhen the response value is reached, the voltage monitor requires the response time tan until the alarm is activated.A preset response delay ton (0...300 s) adds up to the device-related op-erating time tae and delays alarm signalling (total delay time tan = tae + ton).If the fault does not continue to exist before the time of the response delay has elapsed, an alarm will not be

3.2.13 Erasable history memoryThe first alarm value that occurs will be stored in this memory. Subse-quent alarms do not overwrite this "old value. The memory can be cleared using the Clr key in the menu HiS.

3.2.14 Alarm LEDs show which relay is in the alarm stateWhen 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.

When the menu item LEd is deactivated, AL1 signals overvoltage, AL2 signals undervoltage, both LEDs AL1 and AL2 light up in case of frequency alarm.

3.2.15 Starting a device using a simulated alarm S.ALIf the menu item S.AL has been activated in the out menu, K1 resp. K2 switches back to the alarm state once the supply voltage is applied. This alarm state is maintained for the set duration t + ton1. Once this time has elapsed, K1 resp. K2 switches back to the initial position provided that no fault is detected at the measuring input. The following diagrams show the effect of a fault during a simulated alarm.

Faults at the measuring input and the resulting condition of the alarm relay K1 (K2) are shown as a hatched area.The fault for K1 shown in the time diagram below, by way of example, has started during the S.AL phase:

After connecting a brand-new VME421H-D-2 to a standard sys-tem of Un = 230 V 50 Hz, the response values are automaticallyset by the internal preset function:Overvoltage = 253 V (230 V + 10 %) (50 Hz + 1 Hz)Undervoltage = 196 V (230 V - 15 %) (50 Hz - 1 Hz)Other operating ranges of the preset function are given in thetechnical data "response values" and in the description of thefunction.37
