Description:
This auxiliary control unit is a four-position device that can be used for double- and single-acting lifting cylinders. It has gate-sealed cylinder connections A and B. This means extremely low leakage rates is permissible at high loads. The consumer connections A and B can be found on the top and bottom of the housing. The device has a detent position in the lifting position that is equipped with an automatic hydraulic limit switch, and that releases at 180 bar. When switching via the lowering position, the locked float position is engaged. This cannot be unlocked hydraulically (consumer connections A and B are connected to the return line). The float position can be used on double- and single-acting lifting cylinders as locked lowering position. The auxiliary control unit can be switched from double- to single-acting and vice versa. This is also possible during operation. The control lever is included in delivery.
