AutoSet Troubleshooting

As you are running your press, you may come across some situations that you will need to
correct. Here are some situations that you may encounter and how to troubleshoot them.

When none of the load or setpoint LEDs are displayed

If you are not getting any load or setpoint readings:
Check that you have power. Also check that power is present at both sides of
fuse #1. Refer to "Connecting AC wires to power source" in Chapter 2.
Check the wiring of the strain links. Refer to "Mounting and connecting strain links" in
Chapter 2 of this manual. If you are still having difficulty, contact Data Instruments.

When either of the load displays shows no tonnage

If one or both of the load displays always reads "0" tons:
If you had installed the optional zero cam switch (LMCS), check that it has been
connected properly. Be sure that the zero cam is closed to ground during the top
of the stroke and open at bottom. Look at where the red and blue magnets are
positioned on the crankshaft. Refer to "Installing a zero cam" in Chapter 2.
Check that the mounting and wiring of the strain link affected was done correctly.
Were the strain links mounted on a flat, clean surface? Were they wired correctly?
See "Mounting and connecting strain links" in Chapter 2 for more information.

When the tonnage is lower than it should be

If when running your press, you find that that tonnage is lower than you think it should be:
If new installation or calibration:
If you had installed the optional zero cam switch (LMCS), check that it is closed
to ground during the top of the stroke and that it opens at bottom. Also look at
where the red and blue magnets are positioned on the crankshaft. See the section,
"Installing a zero cam", in Chapter 2 for more information.
Check that the mounting and wiring of the strain link(s) affected was done
correctly. Were they wired for tension or compression? See the section
"Mounting and connecting strain links" in Chapter 2 for more information.
Check that the calibration was done properly. Are the calfactor(s) correct? Are
the calfactor(s) you set the same as the one(s) you wrote down during the
calibration? Refer to Chapter 3 AutoSet Calibration if needed.
If existing installation:
Check for a stretched or broken tie rod on straight side presses.

What happens when power is turned off and restored

When the power to the AutoSet is turned off, the tonnage readings and setpoints are lost.
However, the calibration information and full scale tonnage settings are retained. When
power is restored, the tonnage displays will read zero and the setpoint displays will read
120% of full scale tonnage. The AutoSet will automatically recalculate setpoints after
the appropriate number of strokes.
