Minimum and Maximum Voltage :
The minimum and maximum voltage values are stored. User may read or delete
these values. Stored minimum and maximum voltage values remain stored,
when the power supply is off.
Setpoint ( s p v e s p
): When the AC current which flows through the device
is over the high setpoint value or it is under the low setpoint value, the output
relay is switched on in order to generate an error signal at the end of programmed
delay time ( The point which is on the below right corner of display blinks). If
the AC current value returns within preset limits, before the end of the delay
time, the relay resets itself and no tripping occurs.
Latch Function ( ) : Latch function is used to select the output relay
operation mode. Either oF or on position may be selected.
At position oF: If the current value returns to preset limits, output relay is
switched off.
At position on: Even if the current value returns to preset limits, output relay
remains switched on and switches off only by pressing the Set button.
Instant Tripping ( ) : If the AC current value is over the1,5 times of setting
value or it is under the 0,5 times of setting value, the output relay is switched
on without any delay time. This function is user-selectable.

EVM-3 (Voltmeter) :
EVM-3 is designed for accurate measuring of the AC RMS voltage and for
saving the minimum and maximum values of the measured voltages. Minimum
and maximum values remain stored in the memory when the power supply is
off. This stored values can be read when the power is on. Although EVM-3 is
mainly used for electrical panels, this device can also be used with any application
in which accurate voltage readings should be done between 10-600V. The
measurement (3-4) and power supply (1-2) connections are located on the rear
panel and the digital display is centered on the front panel.
EVM-3C (Setpointed Voltmeter) :
EVM-3C has the same functions of the EVM-3. In addition to these functions,
an high voltage level and time delay can be set. When the measured voltage
is over the high set point value, the output relay is activated at the end of the
adjusted time delay, generates an alarm signal and display starts blinking.
Note: If the measurement that the device made or the primary value is over
9999 V, k led on the device is on.
Note: If the voltage on the measurement input of the device is over 600 V or
measurement according to the ratio of entered primary/seconder is over 999.000
V, there will be   on the display.
Voltage Transformer Ratio: Voltage transformer can regulate the primary and
secondary voltage values separately. Primary value can be entered between
1-40.000 and the secondary value can be entered between 1-250.
Note: If the primary and secondary values changed, control the setpoint
and hysterisis values. This is important for the device working the way
that it was arranged.
Precautions For Installation and Safe Use
Failure to follow those instructions will result in death or serious injury.
Disconnect all power before working on equipment.
When the device is connected to the network, do not remove the front
panel.
Do not try to clean the device with solvent or the like. Only clean the
device with a dried cloth.
Verify correct terminal connections when wiring.
Electrical equipment should be serviced only by your compedent seller.
Only for rack panel mounting.
