Type Description
Bool If a 1 is applied on this input and if there is no fault, the
pump will be activated.
If the pump does not run or is not at a standstill the fol‐
lowing causes are possible:
PROFIBUS
n
Pump is not in PROFIBUS
n
PROFIBUS
n
Configuration is not correct
n
Pump is manually set to stop
n
Setpoint is on 0% (irSetpoint_0_100)
n
ixFault_Lock = 1 and oxError = 1 or oxProfibus = 1
n
Use Profibus Workaround
n
Adapt iiCycle_Error
Bool Resets the bit messages oxWarning, oxError and oxEr‐
rorProfibus. Resets the pump (positive flank sent).
Bool If 0, then the pump does not include a locking mechanism
for stored faults.
Logical link:
Start pump = ixStart_Stop
i.e. because the faults oxError and oxErrorProfibus
require acknowledgment, the pump automatically starts
up again if there is a fault on both sides.
If 1, then the pump does not include a locking mechanism
via fault messages oxError or oxErrorProfibus.
Logical link:
Start pump = ixStart_Stop & oxError = 0 & oxErrorPro‐
fibus = 0
i.e because the faults oxError and oxErrorProfibus
require acknowledgment, the pump does not automati‐
cally start up again if there is a fault on both sides.
Real Entry of the setpoint of the metering pump in %.
The formula of the calculation is:
Set frequency = MaxFrequency * irSetpoint / 100
Through the real number the speed on the stroke can be
precisely selected, because the entry of 49.99%, for
example, is possible.
Likewise a direct connection of the integrated S7 con‐
troller is possible. For this the output parameter LMN
must be connected on this input.
