Emerson KJ2201X1-PW1 original module eddy current sensor

Description

• If the valve is closed, isolate it hydraulically KJ2201X1-PW1 to prevent any bump when inserting

the new VP.

• Switch the MA driving the VP position to manual, and move the target position

to zero. This is done to avoid jostling the valve when the new VP is inserted.

• For large machines, switch the valves to ‘single’ or ‘full arc’ mode from

‘sequential’ or ‘partial arc’ mode.

• Keep fifirst stage, or impulse pressure, KJ2201X1-PW1 control loops in service to respond to any

upset during the maintenance.

• If the replacement is due to a suspected or intermittent problem, that can only

be corrected by replacement, but the VP is operating, fifirst close the valve by

switching the MA to manual, driving the valve to 0%, and then isolate it

hydraulically

1. Once the valve is closed and in a safe condition, remove the bad VP.
2. Insert the replacement VP into the base unit.

graphic.

4. View the reported feedback position. It should be close to 0%. If it is, the valve

can be operated without calibration.

5. View the servo voltage at terminal screws 14B and C, and 13B and C. Note that

if the servo voltage has integrated to a few KJ2201X1-PW1 volts negative, and hydraulic flfluid is

applied suddenly, the valve will ‘pop’, and the on-board PI will respond and

bring the valve back to the target position of 0%. If the target position of 0% is

less than ‘seatLimit’, servo voltage will be positive, thus driving the valve hard

to the seat.

6. With the valve closed, you can execute the 0% calibration sequence to fifind the

exact reading for the 0% position. If you believe KJ2201X1-PW1 the 100% calibration is close,

the valve can then be operated without calibrating the 100% position, since

there is little flflow change when the valve is fully opened.

7. Verify that the VP is in the normal operating mode as indicated by the card edge

LED.

8. When you determine that it is time to operate the valve, un-isolate the valve

hydraulically, drive the target position of the MA to the desired position, and

then switch the MA back to ‘auto.’
