NOTICE! Gear unit damage
The gear unit may be damaged by overheating.
• The drive unit may only be commissioned after the pump and the pressure monitor for the pressure circulation
lubrication have been connected and commissioned.
• During operation, the function of the lubricant circulation must be ensured by means of a monitoring system.
• The gear unit must be shut down immediately in case of failure of the lubrication circulation.

All gear units equipped with lubricant circulation are usually equipped with a pressure switch to
monitor the pump function. The connection of the pressure switch and the evaluation of the signal
must be carried out by the operator. The pressure switch must be connected so that operation is only
possible if the oil pump has built up pressure. If the pre-set pressure is undershot, the applied electric
signal is interrupted by the pressure switch.
Information
Lubricant circulation
• If pressure circulation lubrication is used, the operational viscosity of the gear oil on start-up must not exceed
1800 cSt. For ISO-VG220 this corresponds to a temperature of at least 10 °C for mineral oil, and a
temperature of at least 0 °C for synthetic oil.
• The pressure monitor can only be evaluated after the pump has been put into operation, as a pressure must
first be built up.
• During commissioning, a lower pressure is permissible for a short period.
• The pressure monitor is usually set to 0.5 bar.
