Interlocking shaft of ISM15_LD_8, MD_1, MD_3, HD_1 operation by release cable
The release cable operating stroke is 37±0,5 mm, which is equal 90 degrees rotation angle of cam as shown
in the Figure 100. Minimal bend radius for cable is 100 mm.
There is a possibility to install two remote interlocks which can operate independently of each other. For
ISM15_LD_8, MD_1, MD_3, HD_1 interlocking shaft torque is as follows:

ISM15_MD or ISM15_HD interlocking shaft torque
The interlocking process might be divided into next steps:

“a-b” – backlash;

“b-c” – blocker contacts the magnetic actuator plate;

“c-d” – blocker interacts the magnetic actuator plate;

“d-e” – switching module turns off;
