7.
8.
Connect the encoder cable to J7 of the main circuit board.
Test the encoder by:
a.
Power-up the system. Be careful with the open electronics inside the unit.
b.
Move encoder arm up and down to ensure operation
—
moving arm up should decrease the reading and
moving arm down should increase the reading
c.
If working correctly, power-down system and remove power.
Replace the covers.
9.
10. Power-up unit and calibrate the encoder by using the Encoder Calibration procedure.
Calibrating the Digital Encoder
The Digital Encoder is calibrated at Dynisco prior to shipment. Because the arm is locked into place, calibration
is rarely required. If calibration needs to be checked due to suspected encoder damage, then the following steps
should be followed. If damage to the arm is suspected, then contact Dynisco for assistance.
The following part should be in the tool kit or included with the encoder based melt indexer:
•
Spacer -
.31” diameter x 80mm
long.
1.
Make sure the encoder arm will pivot upward after it is removed from its locking holder. Adjust the arm so it
will pivot upward by doing the following:
a.
If there is an Encoder housing around the encoder, remove it.
b.
Twist the balance nut so that it is against the head of the adjusting screw.
c.
Release arm and it should pivot upwards freely.

d.
Lower arm into its locking holder.
e.
Reinstall the cover and tighten all hardware.
