3. Duplex Filter and Measurement Tube
The duplex filter (1, Fig. 3) and the measurement tube (4) are installed between the
lube oil tank and the lubricating pumps. The differential pressure sensor (6) monitors
the quantity of dirt in the duplex filter (1). If the filter is clogged, the differential
pressure sensor transmits a signal with a failure message to the alarm and monitoring
system. If the filter element becomes clogged, replace it (see paragraph 3.2).
Note: Make sure that the ball valve (8) is opened during operation.
3.1 Duplex Filter
It is necessary to bleed the duplex filter:
D At the first operation
D After you replaced a filter element.
3.2 Filter Element
It is possible to replace a clogged filter element during operation, thus it is not
necessary to stop the oil supply. Do the steps that follow:
1) Move the lever (2, Fig 3) to the other (clean) filter element.
2) Replace the clogged filter element.
