Notes:
1
– Occurrence of fault as "EEPROM Error" – the destruction of EEPROM indicates that the data of the
programmed parameters (Table 2.6) is damaged. To continue the operation, it is necessary to turn off UBZ and
restore the factory settings (5.4.7
– second method).
2
– Occurrence of fault as "Error CALIB" – UBZ improper calibration means that the calibration coefficients of
the measured data are damaged. The continued operation of UBZ is impossible. Re-calibration of the device is
required to be done at the manufacturer factory.
5.7 Emergency Conditions Logbook
When disabling the load relay in the event of fault, UBZ records in its memory the code of the fault, the value
of the parameter on which the fault occurred and time of occurrence.
Note
– The fault time is determined by internal clock of UBZ.
Number of simultaneously stored fault codes is 50. In case of subsequent faults occur, the fault information
is recorded in place of the oldest fault
To view the log, it is necessary to press button " WR/SEL ".
LED " SETUP " will on in flashing mode, and UBZ indicators will display the latest fault (Fig.5.18).
Line 1
– indication of mode (alarm logbook);
Line 2
– number of the fault (1 – means the most recent fault);
Line 3
– mnemonic of the fault as per Table 5.12 and the parameter value at the moment of the fault
occurrence;
Line 4
– time and date of the fault.
Fig.5.18
– Display in the view mode of the fault logbook
View the fault logbook by pressing the UP or DOWN button.
To exit the view log mode, press the button " WR/SEL " or exit will be automatically in 30 seconds after the
last pressing of any button.
Register addresses to read data log of faults via MODBUS Protocol are given in Table 5.8.
5.8 Motor control on UBZ front panel
Depending on the value of the parameter “MotorOp UBZ”, you can control the load relay of UBZ by
simultaneously pressing the UP and DOWN buttons:
– “Off” - no reaction;
– “Start” (motor start is enabled) - the load relay will enabled if ARS time has not finished;
