10.0 ERROR CODES
On power up, the UPR800 will enter a self-test mode to evaluate the condition of the
equipment. If an error is detected, the screen will show an error code number in the
upper display and the mnemonic
Err
, in the lower display.
10.1 Error Codes and Troubleshooting
The errors codes and their possible causes and solutions are as follows:
1
Error during EEPROM access.
Correction
: De-power the instrument and wait for 60 seconds. On power-on the
situation should clear itself. If it does not correct itself de-power 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.
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 SHUNT is turned on, and software
configuration is correctly. Also verify that the wiring is correct, especially that the
Orange wire is on Terminal 14, and the Blue wire is on Terminal 17 with the
Green wire. Disconnect the transducer from the wiring, and either replace the
wire, or check the continuity of EACH wire, and that there is no short between
any of the wires. If the cable is good, 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.)
6
Wrong Reference Junction Measure.
Correction
: The on-board thermocouple cold reference junction was read improperly.
Press RESET to try to clear. If this does not work, turn the instrument off, wait
about a minute, and turn the power back on. Verify that the instrument is not
outside its operating temperature (-20 to 60°C). If the error persists, send the
instrument to Dynisco for repair (See Section 11.)
11
Overload or short-circuit on primary strain gage input, or unconnected “+EXC” or
“-EXC” wire.
Correction:
An instrument set for primary strain gage input with NO transducer
connected will display this error. Connect a transducer to the instrument to
remedy this condition. If there is a transducer connected, disconnect it from the
wiring, and either replace the wire, or check the continuity of EACH wire, and that
there is no short between any of the wires. If the cable is good, 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.
13
Incorrect span value
14
Internal I2C bus communication error with eeproms
15
Internal I2C bus communication error with I/O expanders
RAM
Failure of RAM circuit. There is no correction; the device needs to be sent to
Dynisco for repair.
