3.24 Connecting the oil heater (Option: OH)
WARNING
Risk of fire due to exposed heater bars
• Ensure that the heater bars are fully immersed in the oil bath before switching them on and during
heating operation.
The oil heater is already installed prior to delivery. Observe the manufacturer’s instructions for
connecting the oil heater.
Information
Prevent excessive heat dissipation
The gear unit heat loss is particularly high in installation locations where there are extremely low
ambient temperatures or strong air movements. In such cases, it may be necessary to provide
protective devices against excessive gear unit heat losses if the oil heater cannot sufficiently
compensate for the heat loss.
3.25 Adjusting the brake
WARNING
Risk of brake malfunction from faulty adjustment
A brake malfunction may cause serious injury.
• Adjust the brake correctly as described in the operating instructions before commissioning.
• Use additional monitoring functions (e.g. Option SLW).
Read and observe the instructions of the brake prior to assembly, commissioning and adjusting work.
For details on the options described below, please refer to the dimension sheet or order confirmation.
The brake is delivered in a pre-adjusted state only. Check the settings and correct them as necessary.
The brake is delivered in an applied state.
The brake specifications must always be verified if the operating conditions (power, speed, changes to
the drive or the driven machine) change.
3.25.1 Automatic lining wear correction (option: LWC)
While being operated, the brake lining of a mechanical brake is subject to wear. The option LWC
compensates for this wear by automatically adjusting the brake lining. But the adjusting range is
limited. To maintain an even braking effect, you must check and if necessary correct the adjustment
(residual stroke) in line with the manufacturer’s specifications and during or briefly after commissioning
in particular.
Information
Decreasing braking effect
The braking effect will decrease if the mechanical wear of the brake lining exceeds the adjusting
range of the LWC option. This has a negative effect on the brake response time and the braking
distance.
