The controller output from the master instrument is multiplied by
Slave Factor
/100 % to get the slave instrument setpoint.
In systems other than FLOW-BUS via RS-485,
Slave Factor
is effective only if
Control Mode
is set to 'Analog slave', and the
analog output signal of the master instrument is redirected to the input of the slave instrument.
Example:
·
master output = 80 %
·
Slave Factor
= 50
_
slave instrument setpoint = 80 % x 50 %/100 % = 40 %

This parameter is only functional for FLEXI-FLOW™ models that are equipped with an (internal) shut-off valve.
On FLEXI-FLOW™ models that are equipped with an internal shut-off valve,
IO Switch Status
is used to actuate the valve.
Depending on the valve type, actuation leads to closing or opening the valve:
