2 The SMART function is not able to apply the step change because the manual output value
plus the step value is over / under the output limits.
Correction: Check that the step change is correct; if it appears to be so, lower the change to
a minimal value and try again. If the error still remains, send the instrument to Dynisco for
repair (See Section 11.)
3 Wrong zero measure.
Correction: Check that the wiring is correct. Check that there is NO pressure applied on the
transducer. If there is no pressure on the transducer, and the wiring is correct, contact
Dynisco Technical Assistance at 800-221-2201.
4
SMART function aborted due to an over / under range of the input measure.
Correction: Check that transducer for correct operation, and check the wiring. If both are
working correctly, contact Dynisco Technical Assistance at 800-221-2201.
5 Input calibration error.
Correction: Check that there is no pressure applied to the transducer. If the transducer is at
zero pressure, verify that the wiring is correct. Substitute a known good transducer to
determine if the transducer is damaged. If the good transducer shows the same error, send
the instrument to Dynisco for repair (See Section 11.)
7
SMART function aborted due to a high delay time over constant time ratio.
Correction: Check that the Time Constants (either
AT.TO or AT.TAU) are not too large. If so,
it is necessary to run SMART tuning again, or manually tune the system.
8
Error during the automatic compute of the filter time constant.
Correction: Check that the Filter Time Constants (AT.AFL, AT.FL, A1.FL, A2.FL, A3.FL, or
RO.FL). If they seem correct, change them to a different value and reset the instrument. If
the error cannot be cleared, contact Dynisco Technical Assistance at 800-221-2201, or send
the instrument to Dynisco for repair (See Section 11.)
9 Too many attempts during process estimation.
Correction: The SMART tuning system has reached its limit of tuning attempts, and cannot
calculate a stable parameter set. Try changing the type of tuning, (from PID to PI or vice
versa). If the error cannot be cleared, contact Dynisco Technical Assistance at 800-221-
2201, or send the instrument to Dynisco for repair (See Section 11.)
10 SMART function aborted due to a negative time or a negative process gain.
Correction: The SMART tuning system has inadvertently tuned a negative parameter, and
has stopped. Check either
AT.TO, AT.TAU, or AT.KP and make greater than zero and try
again. If this error persists try changing the type of tuning, (from PID to PI or vice versa). If
the error cannot be cleared, contact Dynisco Technical Assistance at 800-221-2201, or send
the instrument to Dynisco for repair (See Section 11.)
11 Overload or short-circuit on strain gage power supply, or unconnected “-4-EXC” or “-EXC”
wire.
