Two-hand control modules SAFEMASTER
Pressing, punching as well as cutting and/or shearing devices have one thing in common: hazardous closing movements that can cause injuries to the operating personnel. Two-hand switch relay from DOLD on machines and systems protect against such injuries. Safely positioned outside of the area of danger, the operator cannot enter this area before the dangerous movement has come to a complete stop. The DOLD two-hand switching modules not only offer safety, they also save you money as conventional safety controls are no longer necessary.

Technical Information and Features

DOLD safe operation with two-hand switches.

Pressing, punching as well as cutting and/or shearing devices have one thing in common: hazardous closing movements that can cause injuries to the operating personnel. Two-hand switch relay from DOLD on machines and systems protect against such injuries. Safely positioned outside of the area of danger, the operator cannot enter this area before the dangerous movement has come to a complete stop. The DOLD two-hand switching modules not only offer safety, they also save you money as conventional safety controls are no longer necessary.

DOLD BG 5933 and BH 5933 description.

The BG 5933 or BH 5933 enables and disables a safety circuit in a safe way. It is used to protect people and machines in applications with 2-hand buttons on presses for metal products as well as for other production machinery with dangerous closing movements.
Your Advantage:
- Compact, ready to connect 2-hand safety circuit
- Cost reduction by replacing conventional contactor circuits
- Feedback circuit Y1 - Y2 to monitor external contactors used for reinforcement of contacts
- EC-type examinated circuit according to the requirements of the health and safety authorities

DOLD two-hand control module characteristics.

DOLD two-hand control module characteristics.

DOLD two-hand control module technology.

Two-hand control consist of an operating panel featuring two operating elements (control push buttons) which have to be arranged so that both hands must be used for operation. The DOLD elevator module only releases once both control elements are operated simultaneously within 500 ms. The release command is present as long as both control elements remain operated. When one control element is unhanded a new control command can only occur if the other control element is also unhanded and both elements are operated again.
