4.8.2 Oil / air coolers (Option: CS2-X)
The maximum ambient temperature is 40 °C. If higher ambient temperatures may occur, verification
must be made by Getriebebau NORD prior to commissioning.
The permissible lubricant temperature range depends on the lubricant type.
Maximum permitted oil temperatures:
• For mineral oil, the maximum permissible oil temperature is 10 °C to 80 °C.
• For synthetic oil, the maximum permissible oil temperature is 10 °C to 100 °C.
An adequate supply of air must be ensured for oil/air coolers. A free space of at least 30° must be
provided for the air intake. The protective grills and the fan blades must be kept clean.
4.9 Oil heater (Option: OH)
WARNING
Risk of fire due to exposed heater elements
• Ensure that the heater bars are fully immersed in the oil bath before switching them on and during
heating operation.
• The oil heater must be switched off for operation of gear units with a reduced oil fill level (Option:
LCX, VL4, KL4, VL6, KL6, DRY).
The oil heater is equipped with a temperature sensor and a thermostat. The heater is pre-set to a
switch-off temperature of 20 °C. This means that the heater is in operation as long as an oil
temperature of 20 °C has not been reached. Please contact Getriebebau NORD for other switch-off
temperatures.
The oil heater must remain functional when the gear unit is shut down in order to ensure that the oil
temperature does not drop too much.
Information
If an oil heater is used, it is recommended that the gear unit is also equipped with a PT 100 to monitor
the oil temperature.
4.10 Temperature monitoring (Option: PT100)
NOTICE!
Gear unit damage through overheating
• The customer must connect the resistance thermometer to an evaluation device. The operator is
responsible for implementing this interlock
The PT100 is a temperature measuring resistance with which the oil temperature can be monitored.
The PT100 must be connected to a suitable evaluation device and the signal must be evaluated.
The triggering device must be set so that the drive unit shuts down when the maximum permissible oil
temperature is reached.
For mineral oil, the maximum permissible oil temperature is 85 °C.
For synthetic oil, the maximum permissible oil temperature is 105 °C.
