Determine Clamp Position Sensor Values
Important: The following procedure and subsequent set-up information
must be utilized for every different mold used on a hydraulic machine. On
a toggle clamp (with die height adjust), it must be completed only once.
ATTENTION: Incorrect values entered in DYC09 through
DYC12 may result in rapid clamp motion and potential damage
to your mold and cylinder seals. We strongly recommend
utilizing a “dummy” mold on hydraulic machines and no mold
on toggle machines.
To complete the configuration for your clamp position sensor, do the
following:
Important: If your position sensor has zero and span potentiometers to set
the zero reference and linear resolution, do so during this procedure.
1. Move the clamp forward until it reaches its mechanical close stop.
This is the zero position.
2. Remove clamp pressure and/or flow to stop clamp movement.
3. Record this position value (usually 0000) on line 9 of Worksheet 3-E
for MCC23.
4. With your programming terminal, read the signal level returned in
SYS35 (Pro-Set 600 address N41:187) from your position sensor.
You may wish to zero your position sensor at this time.
5. Record this value on line 11 of Worksheet 3-E 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 by the clamp.
9. Record this distance on line 10 of Worksheet 3-E for MCC24.
10. With your programming terminal, read the signal level returned in
SYS35 (Pro-Set 600 address N41:187) from your positioning sensor.
You may wish to span your position sensor at this time.
