To start press motion, we recommend that you use the following bits:
• B151/03 – permit cycle start
• B151/04 – permit run
• B151/05 – permit downstroke (or delayed start)

Example
of the Permit Cycle Start Command B151/03
Use this command in single or continuous mode to ensure that the
piece is in place before pressing Run buttons to start the press.
Include B160/60 if you want to start only from the near-top position.
