The stations are intended for remote control of electric drives for machines and mechanisms in stationary plants and on ground, sea vehicles, where they
are driven manually by operator, as well as for signaling associated with the specified electric drives or other electrical devices.
The stations are intended for operation with 1ExdIIBT6 explosion protection marking – within explosion hazardous industrial areas, vehicles and storage facilities for products of chemical, oil-refining, gas and other branches of industry.
Station explosionproof metal enclosure consists of the body and cover. By the Customer’s request inside the enclosure button cells with contact blocks of
BKV type ensuring switching of electric circuits; instruments; switches; light indicators are installed on the cover.
“Stop” button drive is made in mushroom form with self-locking. The main actuator of the stations are contact blocks. The blocks have one normally open (NO) and one normally closed (NC) contacts. Terminal clamps of blocks allow connecting of two wires with cross section up to 2.5 mm2 each or one wire with cross section up to 4 mm2.
PVK – Х1 – Х2 – Х3 – Х4 – Х5 – Х6 – Х7 – Х8 – Х9
Х1 – designation of used enclosure and its overall dimensions
Х2 – number and type of buttons by nPх-nSх diagram, where n- number of buttons, P – cylindrical button “START”, S – mushroom button “STOP”, x -button color (G – green, B – blue, R – red, Bl – black, Y – yellow)
If necessary contact diagram shall be indicated. For standard version of “Start” button 1 normally open contact (1NO) is used, for standard version of “Stop” button 1 normally closed contact (1NC) is used. For standard version “Stop” button has self-locking. For version without self-locking index “(w/o s/l)” shall be indicated additionally.
In case of button absence X2 index shall not be indicated.
Х3 is an explosion protection marking. Figure “2” indicates 1ExdllBT6
