Filtration
Remote charge pressure filtration
The remote pressure filter head is designed with a filter bypass valve and noncontacting bypass sensor.The pressure differential acting on the filter element also acts on a spring biased bypass spool. This spoolis designed with a magnetic area. When a certain spool position is reached, the magnet closes a switch inthe bypass sensor which allows R2 to be in parallel with R1. This occurs without any mechanical contactbetween the spool and the bypass sensor.
The position of the bypass spool is indicated by the change in the measured sensor
resistance. The change in resistance occurs when R2 is switched in and out of the circuit. When the filter isnot being bypassed, the nominal measured resistance is 510 ohms. When the switch is closed, thenominal measured resistance is 122 ohms.
The bypass spool is designed so the bypass sensor switch will be closed before oil bypasses the filterelement. This gives the machine operator an indication that the filter is very close to bypassing and afilter replacement is required.
For cold start conditions, it is typical that the filter may bypass for a short amount of time while the oil iswarming up. At normal operating oil temperatures, a system that does not yet need a filter replacementwill operate in the non-bypass mode. The addition of an oil temperature sensor and additional controllogic, is recommended to properly determine if a filter replacement is required.

Bypass valve and bypass sensor
A common spool is used to activate both the bypass sensor and bypass function leading to the assurancethat the bypass sensor will be closed before the bypass is engaged. The bypass sensor occurs at a filterpressure drop of 4.4 +/-0.7 bar. The minimum pressure drop between bypass sensor and open bypass is1.0 bar.

The bypass sensor is activated by the magnetic bypass valve. For proper function it is required to have nosteel parts around the sensor within in below radius. No steel parts are allowed within a radius of 150 mm[5.91 in]. Moving steel devices or parts are not allowed within a radius of 250 mm [9.84 in].
