Configure the QDC Module's I/O

3-11
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.
Important: If your position sensor has a potentiometer to set the zero
reference, do so now.
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.
Important: If your position sensor has a potentiometer to set the span
(linear resolution), do so now.
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 Ejector Position Sensor
ATTENTION: Be sure to open the clamp sufficiently to allow
full ejector travel before proceeding. Otherwise, you could
damage the ejectors and/or the mold.
To complete the configuration for your ejector position sensor, do the
following and enter the results on Worksheet 3-E:
1. Move the ejector backward until it reaches its mechanical retract stop.
This is the zero position.
2. Remove ejector pressure and/or flow to stop movement.
3. Record this position value (normally 0000) on line 13 for MCC31 on
Worksheet 3-E.
