5 Axial piston variable pump | A4VSO Series 10, 11 and 30
Operating data monitoring – X parameters
Operating data monitoring – X parameters
Safety instructions for temperature class T3–T1
ATEX category II 3G Ex h IIC T3–T1 Gc X
To observe the maximum leakage temperature of 90 °C,
at least one of the following measures must be taken and
checked regularly:
▶ Check the leakage temperature at port T or R(L)
(maximumdistance 30cm)
▶ Check the maximum inlet temperature of 60°C at the
suction port
▶ Check a maximum inlet temperature that must be
determined for the following operating points when
commissioning:
– Maximum working pressure and maximum
possible flow
– Maximum working pressure and minimum flow
Also monitor the reservoir level. Take appropriate action if
the temperature exceeds limits.
ATEX category II 2G Ex h IIC T3–T1 Gb X
To observe the maximum leakage temperature of 90°C,
the following measures must be taken:
▶ Continuously monitor leakage temperature at each
pump with a temperature sensor on ports T or R(L)
(maximum distance to port 30cm).
▶ Connect the temperature sensor with a switching-off
for the system at the limit temperature of 90°C.
▶ This shut-off function should be tested during
commissioning; see Chapter8.1.1 of the instruction
manual.
▶ Reservoir level monitoring is also required.
Safety instructions for temperature class T4
ATEX category II 3G Ex h IIC T4 Gc X
To observe the maximum leakage temperature of 80 °C,
at least one of the following measures must be taken and
checked regularly:
▶ Check the leakage temperature at port T or R(L)
(maximumdistance 30cm)
▶ Check the maximum inlet temperature of 50°C at the
suction port
▶ Check a maximum inlet temperature that must be
determined for the following operating points when
commissioning:
– Maximum working pressure and maximum
possible flow
– Maximum working pressure and minimum flow
Also monitor the reservoir level. Take appropriate action if
the temperature exceeds limits.
ATEX category II 2G Ex h IIC T4 Gb X

(maximum distance to port 30cm).
▶ Connect the temperature sensor with a switching-off
for the system at the limit temperature of 80°C.
▶ This shut-off function should be tested during
