4.2. Description of the operation and control functions
After the plug of the safety foot switch has been plugged into the socket (Pos.-No. 2) and the
key of the power switch (Pos.-No. 1) has been turned the working process can be initiated
by actuating the safety foot switch (Pos.-No. 7). The crimping process proceeds
automatically and stops by itself when the max. pressure has been reached. The crimping
process can be stopped at any time by releasing the safety foot switch. The power control
lamp (Pos.-No. 3) indicates the user that the tool is ready to operate.
The tool is equipped with a brake which stops the crimping process immediately after the
safety foot switch have been released.
On demand the operating pressure can be monitored by a pressure clock.
4.3 Description of the crimping procedure
A crimping process is characterized by the closing motion of the dies. The cable lug or
connector will be positioned in the stationary half of the die. The piston will push the
moving part of the die towards the compression point.
The crimping process is complete when the dies are completely closed and the maximum
operating pressure is reached. When the max. operating pressure is reached the safety valve
opens and directs the pressure medium (hydraulic oil) back into the reservoir.
Detailed description about the assembly of the connecting material can be taken from the
assembly instructions in our catalogue chapter 12.
