The resulting reference can be shown on the LCP
control unit’s display by selecting Reference [%] in
parameters 0 09-012 Display readout and can be
shown as one unit by selecting Refere nce [unit].
The sum of the external references can be show n on

. Select External reference, % [25] in parameters

It is possible to have both references and external
references simultaneously. In parameter 214
Reference function a selection can be made
to determine how preset references should be
added to the external refe rences.
There is also an independent local reference in
parameter 003 Local reference,inwhichthe
resulting reference is set using the [+/-] keys.
When the local reference has been selected, the
output frequency range is limited by parameter
201 Output frequency low limit, f
MIN
and parameter
202 Output frequency high limit, f
