Interlocking
Interlocking mechanism
Interlocking mechanism of the module is based on operation of an interlocking shaft that can be rotated clockwise or
counter-clockwise. When the interlocking shaft is rotated clockwise the module becomes acceptable for “close” and
“open” operations. Hereinafter this position of the module is called “unlatched”. When the shaft is rotated in reverse
direction, i.e. counter-clockwise, the module becomes “open and locked”.
If the module is closed, rotation of the interlocking shaft from “unlatched” to “open and locked” position leads to the
manual tripping of the module and afterwards to the mechanical blocking of the actuator.
Working principle of the mechanical interlocking mechanism (Figures 28, 29, 30, 31, 32).
Figure 28
Interlocking shaft in unlatched position. ISM is open.
Figure 29
Interlocking shaft in unlatched position. ISM is closed.
Figure 30
Initial state: ISM is closed. Turn interlocking shaft
counter-clockwise to locked position (manual tripping).
Figure 31
Interlocking shaft in locked position. ISM is open.
Figure 32
Initial state: ISM is open and locked.
Turn interlocking shaft clockwise to unlatched position.
