Control bits (transmitted data bytes 0…3)
Byte Bit Name Description
0 Release (start / stop)
1 = General release (conveyor belt running). Release of weight check and automatic zeroing.
1 Clear bag counter / total
1 = Bag counter is reset and the total weight deleted
2 Activate weight check
1 = Ready for start (bag-detecting light barrier covered)
Edge 1 -> 0 = detection of end of bag when light barrier is no longer covered. Starting of time TCON.TSTD after which weight is adopted. 3 n.u. 4 n.u. 5 n.u. 6 n.u. 0 7 Acknowledge "New values ready"

Status bits (received data bytes 0…3)
Byte Bit Name Description
0 Operation 1 = Weight check is released (control bit "Release" = 1) 1 n.u.
2 Weight checked 1 = Bag has been checked. The signal remains active for the period TCON.TDO or, in case of an alarm, until the alarm is cleared.
3 Underweight 1 = Bag is underweight outside the tolerance REC.T1– or REC.T2–. The signal remains active for the period TCON.TDO or, in case of an alarm, until the alarm is cleared.
4 Overweight 1 = Bag is overweight outside the tolerance REC.T1+ or REC.T2+. The signal remains active for the period TCON.TDO or, in case of an alarm, until the alarm is cleared.
5 Weight in tolerance 1 = Bag is within the tolerances REC.T1 and REC.T2. The signal remains active for the period TCON.TDO or, in case of an alarm, until the alarm is cleared.
6 Weight is outside tolerance
1 = Bag is outside the tolerances REC.T1 and REC.T2. The signal remains active for the period TCON.TDO or, in case of an alarm, until the alarm is cleared.
