—Safety recommendations

The warming contained in this document are all-important for safety; special attention must be paid

to the following symbols:

Installation and commissioning must be carried out by qualiﬁed person; Thytronic assumes no re-

sponsibility for damages caused from improper use that does not comply all warning and caution in

this manual.

In particular the following requirements must be met:

• Remove power before opening it.

• Verify the voltage absence by means suitable instrumentation on relay connections; attention must

be paid to all circuits supplied by external sources (binary input, CT, etc...)

• Care must be taken when handling metal parts.

—Insulation tests

After insulation tests, hazardous voltages (capacitor charges,...) may be arise; it is advisable to gra-

dually reduce the test voltage avoiding to erase it abruptly.

CAUTION Minor personal injury or property damage can result if proper precautions are not taken

DANGER Death, severe personal injury or substantial property damage will result if proper precautions

are not taken

WARNING Death, severe personal injury or substantial property damage can result if proper precautions

are not taken.

CAUTION

Settings must be established on the basis of a coordination study.

Numerical values inside examples have educational purpose only; they don’t be used, in no way,

for actual applications.

residual nominal currents, auxiliary voltage range and CE mark[1]:

• Test label with following informations: data, serial number and test operator signature[2].

—Environment

The XMR device must be employed according to the environment conditions shown (see technical

data).

In case of different environment conditions, appropriate provisions must be provided (conditioning

system, humidity control, etc...).

If contaminants are present (dust, corrosive substances, etc...), ﬁlters must be provided.

Start Leave an initial condition or reset condition (Pickup)

Trip Operation (with operate time)

Operating time Duration of time interval between the instant when the characteri-

stic quantity in reset condition is changed, under speciﬁed condi-

tions, and the instant when the relay operates

Dropout ratio The ratio of a reset value to an operate value in well-speciﬁed con-

ditions. The dropout ratio may be lower or greater than 1 according

as an over or under element is considered

Reset time Duration of the time interval between the instant when the characte-

ristic quantity in operate condition is changed, under speciﬁed con-

ditions, and the instant when the relay operates.

The stated reset time is related to a step variation of characteristic

quantity in operate condition to the reset condition.

Overshoot time The critical impulse time for a relay which is in its reset condition, is

the longest duration a speciﬁed change in the input energizing quan-

tities (characteristic quantity), which will cause the relay to change

to operate condition, can be applied without the relay switches. The

overshoot time is the difference from the operate time and the cri-

tical impulse time. The declared values for the overshoot time are

applicable with the lower setting value of the operation time.
