Appendix VIII
In Case of Difficulty
Setra scales are designed to be easy to use. If, however, you have reached a state in
which the scale will no longer follow your instructions, you may wish to “reset” the
scale. It is possible to do so by following this sequence.
1. Remove all weight from the pan.
2. Press the
—
and
clear
keys to clear the display and set all registers to zero.
3. Press the
zero
key. This sets the displayed reading to zero.
If this procedure does not solve the problem, try briefly unplugging the scale from its
power source; then, plug it in again. If any unusual messages are displayed during
the warm-up period, contact a Setra Authorized Service Center or Setra Systems,
Inc., as service may be required. (During the first 30 seconds of operation, the scale
normally performs a segment test, says “HELLO”, then counts down to zero.)
If the scale displays "d-noS", press the
setup/cal
key as described under "Restoring
the Factory Defaults" in Appendix II. After returning to the factory defaults it may be
necessary to reenter User Defined Units (see Appendix I) and User Set-Ups (see
Appendix II). These include X units , T units, printer formats, bar code label formats,
baud rate, the dual scale mode, minimum sample size, minimum accuracy, tone
enable/disable and span calibration. If these user units and user setups are not
reentered the scale will default to factory settings.
If the scale displays "UnAbLE" during calibration, make sure you are using the
correct calibration weight. See Appendix III, "Calibration." Try performing the steps
above to reset the scale prior to calibration.
If you are experiencing difficulty in sampling during a counting operation, check the
setups of the scale. See Appendix II, "Setup Functions."
For problems with the RS-232 interface, first make certain that the RS-232 cable is
securely fastened to the scale and the peripheral device. Next, reset the baud rate of
the scale and external device to be sure that they are identical. See Appendix II,
"Setup Functions." Now, make certain the data formats are identical. See Appendix
VI, "RS-232 Serial Data Communications." If data transmission or reception is still not
possible, be certain that the cable is the correct type. (When communicating with
certain types of devices, especially computers, it may be necessary to "cross" the
receive and transmit lines of the interface. That is, the receive line of the scale must
connect to the transmit line of the external device. Likewise, the transmit line of the
scale must connect to the receive line of the external device. These special cables
can be purchased from a computer dealer.) See Appendix VI for more information.
If the problem still persists, contact your dealer or Setra Systems, Inc.
