2) Working with the ZT-SLIM Units
ZTSLM ZT-4
Pull Tabs
The ZT-SLIM are compact units with a lot of connections on the top and bottom. Use the Pull Tabs to
hang the units on the Din Rail as shown while you move the units around to make connections or
measurements.

3) Wire Termination
The ZT-SLIM package comes with wire ferrules of different sizes. Use them to terminate all wires.
They provide strain relief which make the wires connect better.

13) Calibration Procedures
1) Before calibrating the unit, verify each piece of hardware is connected and set up properly.
2) With the sensors placed in the best possible location, (see appendix), torque the sensors
down to 150 in-lbs on the sensor bolts. Do not put the sensor enclosure covers on yet.
You will need to test each sensor location.
3) Find the shut height of the press.
•Jog the press until the ram is at bottom dead center (BDC) or 180º without the load cells
or die in the press.
•Determine the amount of spacers needed with your load cell. Cycle the press without
load cells to insure correct height.
4) Place the load cells in the correct position in the press.
•All load cells should be equal distance from the sides and front and rear. For example,
12” from the sides, 10” from front and rear. Load cells are typically placed at each
corner of the press’s bed.
•Cycle the press without hitting the load cells first.
•Place cardboard on the top and bottom of the load cells.
5) Set ZT-4 dip-switches as shown. set all gain pots to fully clockwise, then dial each gain pot
about 12 turns counter-clockwise to start.

ZT-SLIM User’s Manual
6) Balance the tonnage sensors.
•Go to the Calibration page in SlimWare and select “Display Balance”.
•Adjust the ZERO pots until the Balance reads zero in each channel.
7) Cycle the press.
•Select “Capture Tonnage” in SlimWare.
•Further adjust the shut height so that the press impacts the load cells and generates a
load at 100% of press capacity. See warning below.
8) Adjust the gain.
•Run the press for 2 cycles at capacity.
•Compare the tonnage readings in SlimWare with the load cell readings.
•Adjust the GAIN pots.
•Repeat until the SlimWare readings match the load cell readings.
•If less gain is needed, change the Gain switch to X1.
WARNING
Depending on the press capacity and the size of the load cells
being used, loading the press at capacity with load cells could
indent the ram or bolster. If this is a concern, you may choose
to calibrate the press only up to 80% of capacity.
