★1. Whenever setting pressure, make sure the full cut-off pressure never exceeds the maximum intermittent pressure.
★2. When operating the pump exceeding the rated pressure, operating conditions are restricted.
Refer to page 31 for the details.
★3. Maximum flow differs to shaft speed.
The value listed above indicates shaft speed of 1800 r/min.
For other shaft speed calculate by the ratio of shaft speed.
■ Pipe Flange Kits
For Pipe flange, refer to form of pressure compensator type on page 32.
■ Instructions
● Input Signal
The pump is on unload condition when the pump is operated without input signal voltage.
● Electric Source
Always turn off electric source whenever the connector for swash plate tilt angle sensor is removed.
● Compensation of Pump Maximum Regulated Flow at Frequency
If the same maximum flow is required at 50 Hz or 60 Hz, connect short plug in the amplifier to 60 Hz at the place where supplied
frequency is 60 Hz. At this condition, maximum flow comes to the same value at 50 Hz.
If short plug is used at 60 Hz without making the change, maximum flow increased in proportion to frequency.
● Painting on Amp. Box and Solenoiod
To maintain suitable radiation effect, the amp. box and the solenoid of the control valve should not be painted.
