In Case Of Difficulty; Appendix Vi - Setra Systems L Series User Manual

Setra balances 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 tare 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 cal key as described under "Restoring the
Factory Defaults" in Appendix I. After returning to the factory defaults it may be
necessary to reenter User Defined Units (see Section IV) and User Set-Ups (see
Appendix I). These include X units , T units, baud rate, 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 II, "Calibration." Try performing the steps above to
reset the scale prior to calibration.
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 I, "Setup
Functions." Now, make certain the data formats are identical. See Appendix IV, "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 IV for more information.
If the problem still persists, contact your dealer or Setra Systems, Inc.
