KVE Series 2
For Explosion-Proof Contact Blocks:
KVE – Х1 – Х2Х3 –(wХ4)– Х5 – Х6-Х7-Х8 –Х9 … where
Х1 – series number 2
X2 X3 – type of contact configuration:
1 – normally open,
2 – normally closed;
Possible combinations: 21, 11, and 22.
w (optional) – the symbol is added when ordering a KVE unit with a pre-installed cable;
X4 (optional) – the symbol indicates the cable length in meters when ordering a KVE
with a non-standard cable length (different from 1 m);
X5 – voltage:
AC/DC12
AC/DC24-36
AC/DC110
AC220-380
AC/DC220
X6 – control type:
1 – momentary pushbutton;
2 – double pushbutton;
3 – mushroom-head latching pushbutton;
4 – mushroom-head latching pushbutton with key;
Х7 – text (by default, printed on an adhesive thermal label; for individual orders — on a stainless steel nameplate):
1 – (none)
2 – on
3 – off
4 – start
5 – stop
6 – auto
7 – manual
8 – fault
Other inscriptions available upon request.
X8 – colour:
1 – white;
2 – red;
3 – green;
4 – yellow;
5 – blue;
6 – black;
X9 – illumination:
0 – none;
1 – available (only for momentary pushbuttons)
* If any position such as X1, X2, etc., is not required, use “0”. If several positions at the end of the code (e.g., “options”) are not required, simply finish the code.
