For each load cell connected to the web tension electronics PFEA111/112, a maximum load
memory, with the range ±6.5 x Fnom, will store the highest load that is applied to the load cell.
The maximum load consists of:
• Load cell zero signal (with no load on the load cell)
• FRT, applied force component of tare in the measuring direction of the load cell
and
• FR, measured force (force component of tension in the measuring direction of
the load cell).
The maximum load memory can be reset if a load cell is replaced.
3.12.9.2 Reset A/B
Reset A sets “MaximumLoad A” to zero.
Reset B sets “MaximumLoad B” to zero.
3.12.9.3 Simulation function
Simulation can be set to ON or OFF.
If simulation is set to ON, the parameters PercentOfFnomA and PercentOfFnomB will be
displayed. PercentOfFnomB is not shown if Single side A has been selected in ObjectType and
PercentOfFnomA is not shown if Single side B has been selected in ObjectType.
The parameter PercentOfFnom can be set between –100 and +200 in steps of one. When
simulation is set to ON, it replaces the measured value from the load cells. The value +100
means that the value is the same as load cell loaded to Fnom.
Zero set can not be used when simulation is activated. When simulation is set to ON, the red
status led is lit and on the display the message “Simulation” is shown. If “ok” is pressed, the
message is moved to the bottom of the Operator menu in the same way as failure and warning
messages.
SetFactory Default sets the simulation to OFF.
When simulation is set to ON, the default values are:
– PercentOfFnomA = 55%
– PercentOfFnomB = 45%
