Indication of operating states

• It is used to monitor the value of alternating or direct voltage in 1-phase circuits.

• Supply voltage from monitored voltage.

• Monitors voltage exceeding the upper voltage level (Umax) and falling below the

lower voltage level (Umin) – according to the selected function.

• Smooth adjustment of both voltage levels – the lower level Umin is set in % of the

upper level Umax.

• Adjustable time delay (to eliminate short-term voltage drops and spikes).

• Option to select functions with fault state memory (Latch).

• The fault state memory can be reseted by the control input (R).

• Measures true root mean square value of the voltage - TRUE RMS.

Warning

This device is constructed for connection in 1-phase network or direct circuit (according

to the type, voltage ranges must be respected) and must be installed according to norms

valid in the state of an application. Installation, connection, setting and servicing must be

carried out by quali ed electrician sta only, which have perfectly understood the instruc-

tions and functions. This device contains protection against overvoltage peaks and dis-

turbing impulses in the power supply network. For the correct function of the protection

of this device, there must be suitable protections of higher degrees (A,B,C) installed in front

of them and according to the standards, interference of switching devices must be secure-

ly eliminated (contactors, motors, inductive loads, etc.). Before installation, make sure that

the device is de-energized and the main switch is in the “OFF” position. Do not install the

device to sources of excessive electromagnetic interference . Ensure correct installation

by perfect air circulation so that during continuous operation and a higher ambient tem-

perature, the device does not exceed the maximum allowed operating temperature. For

installation and setting use a screwdriver with a width of approx 2 mm. Keep in mind that

this is a fully electronic device and approach accordingly with the installation. Non -prob-

lematic function of the device is also dependent on the previous method of transportation,

storage, and handling. In case of any signs of damage, deformation, malfunction, or miss-

ing parts, don‘t install this device and claim it at the dealer. The product must be treated as

electronic waste at the end of its life.

Connection

Technical parameters

OVER:

If the value of the monitored voltage is lower than the

set upper level „Umax“, the output contact is closed.

If the „Umax“ is exceeded, the output contact will

opens after the set delay (fault state).

If the voltage falls below the  xed hysteresis (O1

function) or the set lower level „Umin“ (O2 function),

the output contact will closes again.

If the OL function (OVER + Latch) is selected, when

the upper voltage level „Umax“ is exceeded, the

output contact remains open even when the voltage

returns from the fault state.

Fault memory reset can be done in three ways:

• Short-term interruption of supply voltage

• Using the control input (R)

• By setting the function switch to position R

(RESET) or any function without memory fault

The RESET state lasts for 3 s after switching the

function switch from the R position to a function

with a memory fault (UL, OL, WL).

When moving to any other function from the R

position, this delay does not apply.

UNDER:

If the value of the monitored voltage is higher than

the set lower level „Umin“, the output contact is

closed. When the voltage drops below the „Umin“,

output contact opens after the set delay (fault

state).

If the voltage exceeds the  xed hysteresis (function

U1) or the set upper level „Umax“ (function U2, U3),

the output contact closes again.

If the UL function (UNDER + Latch) is selected,

when the voltage drops below the lower level

„Umin“, the output contact remains open even

when returning from the fault state. Fault memory

reset can be done as in the previous case.

WINDOW:

If the value of the monitored voltage is lower than

upper level „Umax“ and at the same time higher

than lower level „Umin“, the output contact in

closed. If the „Umax“ is exceeded or drops below

the „Umin“, output contact opens after the set

delay (fault state).

To return from the fault state, a  xed hysteresis is

applied.

If the WL function (WINDOW + Latch) is selected,

the fault state is again stored in memory and

output contact stays open, even when returning

from the fault state. Fault memory reset can be

done as in the previous cases.
