.
SL = slave appears automatically on the
display of the right-hand pump.
The definition: left-hand pump as master and
right-hand pump as slave is thus selected. In this
case, the rotary knob on the slave pump is no longer
of significance. It cannot be used for settings.
The display's position setting cannot be defined at
the slave pump. The position setting at the slave
pump is applied from the specification of the
master pump.
