10.2 Control bits (transmitted data bytes 0…3)
Byte Bit Name Description
0 Start / stop 1 = Start feeding (filling of scales). Allow signal to remain until status bit "Dribble feed" = 1.
1 Clear bag counter / total
1 = Bag counter is reset and total weight is cleared (only possible in step 1 or 9 and with TCON.CCLR = ON)
2 Abort 1 = Switch to step 1
3 FC alarm 1 = Fault in frequency converter when TCON.FINV = ON (generates alarm FINV)
4 Discharge release 1 = Discharge of scales released.
Allow signal to remain until status bit "Discharge" = 1
5 Continue feeding 1 = Continue feeding without zeroing. The signal must be on with "Start". This also enables feeding of a started bag to be completed after an interrupt (e.g. big bag).
6 Acknowledge "Tolerance alarm"
1 = Acknowledgement of tolerance alarms.
Allow signal to remain until status bit "Tolerance alarm" = 0 0
7 Acknowledge "New values ready"
1 = Delete status bit "New values ready" (leave until "New values ready" = 0).
0 Surge hopper empty 1 = Probe in surge hopper is uncovered. Each bag weight is checked and corrected (always check cycle).
1…3 n.u.
4 Release adjustment to nominal value
1 = The bed depth adjustment of the MWSK belt feed to the nominal value is released.
5 Release closing 1 = Closing of the bed depth adjustment of the MWSK belt feed is released.

Byte Bit Name Description
0 Operation 1 = During feeding up to discharge. 1 No. of bags reached Only with bag preselection.
1 = The preselected number of bags is reached.
2 Weighing completed 1 = The weighing process is completely finished (step 5). 0 = When switching to step 8.
3 Feeding completed 1 = The feeding process is completely finished (step 4). 0 = When switching to step 8.
4 Release bagging 1 = Without bag preselection, if the preselected nominal value has not yet been reached.
0 = The preselected number of bags is reached. 5 Dump pulse 1 = Pulse from start of discharge (length 1 s).
6 Tolerance alarm 1 = The bag weight is outside the set tolerance limits REC.TOL+, REC.TOL–.
0
7 New values ready 1 = New values are available (total weights, actual rate). 0 = Control bit "Acknowledge new values ready" = 1. 0 Dribble feed 1 = Filling of scales in dribble flow mode
(also release of frequency converter). Also activated during fast flow. 1 Fast flow 1 = Filling of scales in fast flow mode. 2 Discharge 1 = Discharge of scale.
3 Weight of checked bag
1 = Current bag has been checked (check cycle).
4 Gate opens 1 = The gate of the bed depth adjustment of the MWSK belt feed opens.
5 Gate closes 1 = The gate of the bed depth adjustment of the MWSK belt feed closes.
6 Slide gate in position
1 = The gate of the bed depth adjustment of the MWSK belt feed is in the nominal position (open).
1
7 Gate closed 1 = The gate of the bed depth adjustment of the MWSK belt feed is closed.
0 Discharge delayed 1 = Off-delay signal "Discharge" according to REC.FDEL.
1 Filter cleaning 1 = 200 ms pulse of every nth bag for cleaning a filter according to TCON.CLN.
