Applications
The overtravel distance tester 3TK2835 is intended for checking the overtravel
of linearly operating hydraulic, pneumatic and spindle presses in accordance
with VBG 7n5.2 §11.
Functions
The overtravel distance tester 3TK2835 has four safety circuits, three NO con-
tacts and one NC contact. Two LEDs indicate the functions.
The 3TK2835 tests the overtravel distance in connection with a position switch
every time the control voltage is switched on. The permissible overtravel
distance corresponds to dimension 's' of the cam that is used to operated the
position switch (Fig. V). Obtain dimension 's' from the press manufacturer in
accordance with ZH 1/456 (published by the German Central Office for Accident
Prevention and labour safety, Cologne).
