5.1.3 Control Module

Tavrida Electric Control modules provide the following advantages:
Low Power Consumption
Low energy required to close or trip the ISM, no energy consumption by the ISM in its closed or open state and
optimization of the CM electrical diagrams leads to low CM power consumption – not more than 42 watts while
CM capacitors are charging and no more than 7 watts in standby mode.
Optimal ISM Control
One CM can drive several different ISM types, but is programmed for use with a particular ISM type. The result is
optimal ISM close and trip through a wide range of temperatures.
Self-Diagnostic Functionality
The CM has an internal self-diagnostic system that monitors ISM connection, power supply level and internal states
of the CM. As a result, the CM can indicate issues through the use of LEDs and built-in relays. Unlikely malfunctions
are indicated by the number of corresponding LED blinks.
Wiring Optimization
The CM controls the ISM main contact state via the same circuit used to close or trip the ISM. Therefore, only one
circuit connection between the ISM and the CM is required. The CM can provide external circuits with information
about the ISM main contacts state through the use of built-in relays, which simplifies the switchgear secondary
wiring signifcantly 1) .
Compact Dimensions and Small Weight of CM
The compact size and small weight of the CM (190x165x45 mm, 1 kg) simplifies the installation. The aluminum
housing of the CM provides a high EMC level ("Table 14 - CM EMC Parameters").
The CM is delivered with mounting brackets for mounting on fat surfaces. The LED indicators are visible from two
directions.
1) The position indication of ISM provided by the CM can be incorrect if the CM is not operable due to an absence of auxiliary supply. The
relay keeps its state after the CM power supply disconnection. For demanding applications, conventional mechanical microswitches located
at the ISM can be used.
