SIGN ALARM CAUSE SOLUTION
Err0 Weighing Signal Type Error. Power-on again after making sure that the set value of parameter [111] ‘Weighing Signal Type’ and the switch position of DIP1/DIP2 are matched with the actual weighing input signal.
Err1 RAM Failure. Replace the chip RAM.

Err2.1

Err2.2

 EEPROM Failure. Replace the chip EEPROM.
Err3 Unused.  
Err4 ADC Failure. Replace the ADC module.
oV-Ad Over ADC Range.

Weighing signal exceeds A/D conversion range.

1. Check if the loadcell is connected.

2. Check if the capacity of loadcell is too small.

3. Check if the loading weight is too big.
oL Overload Alarm.

Gross Weight > (Scale Capacity + 9 × Scale Division).

1. Check if the loadcell is connected.

2. Check if the capacity of loadcell is too small.

3. Check if the loading weight is too big.
oV-tr Not meet the condition of Maunal Tare. When Gross Weight is at the state with negative value display, overload alarm or dynamic variation, ‘Manual Tare’ will be invalid.
oV-nZ Over ‘Manual/Auto Zero Limit’. Refer to parameter [123] ‘Manual/Auto Zero Limit’.
tXX.XX Preheating Time Countdown [min.sec].

 Refer to parameter [128] ‘Zero Upon Power Up’, [129] ‘Power Up Zero Time’ and [130] ‘Power Up Zero Limit’.
oV-Zr Over ‘Power Up Zero Limit’. Wait for the preheating time over or press any key to exit.
