9 Operation
risk of explosion and/or fire due to ignition of an explosive atmosphere or of
combustible dust on a hot case surface!
Insufficient monitoring during operation may result in excessively high case
temperature. Serious injury caused by blast pressure and fire may result.
▶
During operation, monitor the fluid level and temperature in the reservoir.
▶
Comply with the specified case leakage pressure and case leakage temperature.
▶
For equipment Category ii 2G ex h iiC t4-t1 Gb X: Monitor the leakage
temperature in accordance with the specifications in this manual.
▶
Observe the operating data; see the data sheet (Part II).
risk of explosion and/or fire due to ignition of an explosive atmosphere or of
combustible dust resulting from damage to a bearing or the rotary group!
Early bearing damage will cause the interior of the axial piston unit to heat up.
Overheating can pose an ignition risk.
▶
Perform both an inspection for unusual noise development and a visual
inspection of external integrity daily.
▶
Check the leakage temperature (or inlet temperature) daily.
(Realized automatically for Equipment Category II 2G Ex h IIC T4-T1 Gb X by
integrated temperature monitoring).
▶
Observe the maintenance interval for the axial piston unit.
(see Table 17).
Only use the product within the performance range specified in the technical data;
see the data sheet (Part II). The machine/system manufacturer is responsible for
proper project planning of the hydraulic system and its control.
Do not alter the settings on the axial piston unit.
▶
If the axial piston unit can no longer achieve the specified torque (pressure),
shut the system down.
