Label

Details the labeling system and how labels are applied to the switches and accessories.

Control Circuit

⚠️ Warning: Installation and maintenance should only be performed by qualified electricians. Ensure the switch is de-energised before work. The control voltage (24Vdc) is non-isolated. Inductive loads require protection from voltage spikes.

Diagrams show the terminal connections for motor operator voltage supply, control terminals (push buttons or selector switch), and state information terminals.

Manual Operation

Describes how to operate the switch manually using an extension handle. Electrical operation is prevented when the manual handle is attached.

Illustrations show the attachment and use of manual operation handles (e.g., OHBZX200-275, OHBZV125) for different switch models.

Electrical Operation

⚠️ Warning: Do not open covers as dangerous voltages may be present. Exercise caution when handling cables and the unit.

Details the process of electrical operation, including the role of the motor operator and its fuse protection (F1).

Impulse Control

Explains impulse control sequences, showing how commands are processed based on timing (e.g., >100 ms). It illustrates the switch's response to sequential commands.

Note: If a new command is given before the switch reaches the previous position, the fuse (F1) may operate.

Continuous Control

Describes continuous control modes, illustrating the switch's behavior under sustained commands.

Locking

Details methods for locking the manual and electrical operation of the switches to prevent unintended changes. This includes using padlocks (Ø5...6 mm) on the switch mechanism.

Locking State Information
