VALVE 1
INTERNAL SWITCH
POINT
MODBUS register:
Data type:
Access:
7280
6402
Float
read
Displays the internal switch point of valve 1 (see function CLOSE VALVE 1 on
Page 138). The value displayed takes the fixed correction quantity and / or the
calculated after run quantity into account.
Display: max. 7-digit floating-point number [unit]
! Note!
The appropriate unit is taken from the function group SYSTEM UNITS
(see Page 15).
DRIP QUANTITY
MODBUS register:
Data type:
Access:
7281
6404
Float
read/write
Displays the after run calculated (averaged) internally.
The value displayed can be overwritten in this function and the after run can thus
be adjusted. The after run quantity is used to optimize the internal switch point of
valve 1.
User input: max. 7-digit floating-point number [unit]
! Note!
• If an after run quantity is specified in this function, it is only used for the first
batching process. The device uses the after run quantity calculated internally as
of the second batching process.
• The appropriate unit is taken from the function group SYSTEM UNITS (ACA),
(see Page 15).
VALVE 1 CLOSING
TIME
MODBUS register:
Data type:
Access:
7282
6406
Float
read
Displays the valve closing time calculated internally.
Display: max. 7-digit floating-point number [unit]
! Note!
• The valve closing time is the period between the switch point of valve 1 and
the first undershooting of the low flow cut off.
• The data can only be taken as a general trend.
BATCHING TIME
MODBUS register:
Data type:
Access:
7283
6408
Float
read
Displays the batching time for the current or completed batch process.
Starting at 0 seconds, the time displayed increases until the batch process is
completed.
Application: The batching time refers to the batch quantity determined in the
function BATCH SUM for the current or last batch process.
Display: max. 7-digit floating-point number [s]
! Note!
• Behavior when controlling the batching process by means of the BATCH
PROCEDURE function:
–STOP → BATCHING TIME is not reset and remains at the current value.
– START → BATCHING TIME is reset and starts at 0.
–HOLD → BATCHING TIME is not reset and remains at the current value.
– GO ON → BATCHING TIME is not reset and continues updating based on
the last time value.
• The BATCHING TIME is also updated during the batching process
