3. Record this position value (usually 0000) on line 9 for MCC23 on
Worksheet 3-E.
4. With your programming terminal, read the signal level returned in
SYS35 (N40:187) from your position sensor. You may wish to zero
your position sensor at this time.
5. Record this value on line 11 for MCC25 (should be at minimum
signal if you zeroed your position sensor in step 4).
6. Move the clamp backward to the mechanical open stop.
7. Remove clamp pressure and/or flow to stop clamp movement.
8. Measure the distance travelled.
9. Record this distance on line 10 for MCC24.
10. With your programming terminal, read the signal level returned in
SYS35 (N40:187) from your positioning sensor. You may wish to
span your position sensor at this time.
11. Record this value on line 12 for MCC26.
You may now download your adjusted values to the QDC module using
the MCC download procedure presented earlier in this chapter.
Determine Values for the Ram (Screw) Pressure Sensor
To complete the configuration for your ram (screw) pressure sensor, enter
on Worksheet 3-E minimum and maximum pressures and corresponding
signal levels from manufacturer’s specifications in MCC17-20. Most
applications require no further spanning. If your application requires
greater accuracy, follow the procedure below:
1. Release system pressure to obtain minimum ram (screw) pressure.
2. Read the pressure gauge at the ram (screw).
3. Record minimum pressure (normally 0000) on line 5 for MCC17 on
Worksheet 3-E.
4. With your programming terminal, read the signal level returned in
SYS34 (N40:186) from your pressure sensor. You may wish to zero
your pressure sensor at this time.
5. Record this signal level on line 7 for MCC19. It should be at
minimum signal if you zeroed your pressure sensor in step 4.
