Operation
6.2.2 Program 2 (without bypass voltage)
For gripping and laying stone layers using only the main clamp. This program is used, for example, if the
position of the laying clamp in relation to the block layer needs to be rotated by 180 degrees every second
laying cycle.
To use program 2, the stopcock (below the clamp suspension) must be moved from the horizontal position
(flow direction) to the vertical position (blocking position) (see illustrations below).
