Setting up and adjusting an AutoSet 1500 calibration kit
Follow the steps below if you are using another AutoSet 1500 with calibration kit for
calibrating your AutoSet 1500. The kit contains two load cells, calibration modules, and
cables. The steps below tell you how to set up and adjust the AutoSet to display the
correct tonnage applied to the load cells.
1. Find the calibration modules. They are small boxes with cables attached. The end
of each cable has a connector that fits into the strain link connector in the AutoSet
box. These modules also have a connector on the box where the load cell cable
connectors screw in.
2. Swing open the front cover of the AutoSet (the one you are using as the
calibration unit). If your unit does not have a plug, connect power to it as
described in Chapter 1—"Connecting AC power and stop circuit." (Do not
connect the stop circuit.)
WARNING
Make sure power supply cover is in place
If you remove the power supply cover to connect 115 Vac
wires, make sure you put the cover back on. The cover fits
over the power supply near the top of the enclosure. It
helps prevent shock if you are working inside the box with
power on.
3. For one cell calibration, take one calibration module and plug the cable into the
slot marked "left input" in the AutoSet box. This slot is at the lower right hand
corner of the box. The connector goes in one way only. If there already is a
connector plugged into this slot, remove it to plug in the connector to the
calibration module.
For two cell calibration, also plug the other calibration module into the slot
marked "right input."
For one cell calibration, you must attach a jumper wire to the connector on the
unused channel.
So pull out the connector from the right input slot. If there is no
connector in this slot, you will have to put one in. Put a jumper wire between slots
2 and 3 (see Figure 2-7 in Chapter 2). Plug connector back in slot. This connector
should have no other wires attached to it.
NOTE:
You can use either the right or left input for one cell calibration. We will
use the left in this procedure. The unused connector in the other slot must have
the jumper wires connected.
