iP
Input list
FiLt
IP1 filter time constant (0.0 -
999.9 seconds).
FLt.2
IP2 filter time constant (0.0 -
999.9 seconds).
Hi.IP
Lo.Ip
Transition of control between
ip.1 and ip.2. (if configured)
The transition region is set by the
values of ‘
Lo.Ip’ and ‘Hi.Ip’.
PV =
ip.1 below ‘Lo.Ip’
PV =
ip.2 above ‘Hi.Ip’
F.1
F.2
Derived function, (if configured)
PV = (
f.1 x iP1) + (f.2 x iP2).
‘
F.1’ and ‘F.2’ are scalars with the
range -9.99 to 10.00
PV.ip Selects
‘
ip.1’ or ‘ip.2’

The next 3 parameters appear if User
Calibration has been enabled. (Refer to
Chapter 7.) By default they are hidden
when in Operator level. To prevent
unauthorised adjustment, we recommend
that they are only made available in
FuLL
access level.
CAL
‘
FACt’ - reinstates the factory
calibration and disables User
calibration. Next 2 parameters
will not appear.
‘
USEr’ - reinstates any previously
set User calibration. All
parameters below now appear.

PV.SL
Shows the currently selected PV
input - ‘

* Do not make adjustments using the
AdJ
parameter unless you wish to change the
controller calibration.
