1)
Based on an operating viscosity of 140 mm
2
/s (cSt) at a back pressure of p = 5 bar.
2)
Mode S3 (periodic intermitent operation) describes the ratio between the pump cycle and the subsequent down time. The following limit values result from a relative ON-time of 20% and a cycle time of
1,25 to 25 min:
Min. cycle time: 1.25 min×0.2 = 0.25 min. Pump cycle with subsequent down time of 1 min.
Max. cycle time: 25 min×0.2 = 5 min. Pump cycle with subsequent down time of 20 min.
3)
When switching inductive loads, take suitable measures to protect the contacts.
4)
Minimum short-circuit current of 6A must be ensured.
