Err3	Signal reversed or not connected.	Connect the loadcell correctly.
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.
HH	Gross Weight Upper Limit Alarm in Stop state.	Refer to parameter [209] ‘Gross Weight Upper Limit’. 1. Modify the set value of ‘Gross Weight Upper Limit’ if it’s too small. 2. Do ‘Manual Dump’ if the weighing hopper has been filled with too much materials.
Pr-PAUSE	Pause state with unexpected power-off.	With unexpected power-off in the auto-batching process, the controller will enter pause state after re-power-on. Press DI button ‘Start/Dev.Ack’ or【ENT】to recover running.

Modify the set value of ‘Gross Weight Upper Limit’ if it’s too small, and then press DI button ‘Start/Dev.Ack’ or【ENT】to recover running. 2. Stop batching and do ‘Manual Dump’ if the weighing hopper has been filled with too much materials.
dI-PAUSE	Manual Pause.	Press DI button ‘Start/Dev.Ack’ or【ENT】to recover running.
OV-PAUSE	Pause state with Positive Deviation Alarm.	Press DI button ‘Start/Dev.Ack’ or【ENT】to recover running.
dn-PAUSE	Pause state with Negative Deviation Alarm.	It’s allowed to do ‘SP3 Manual Re-feed’. Press DI button‘Start/Dev.Ack’ or【ENT】to recover running.
