SP2.H Setpoint 2 high limit
SPrr Setpoint Rate Limit
Hb.ty Holdback Type for setpoint rate
limit (
OFF, Lo, Hi, or bAnd)
Hb Holdback Value for setpoint rate
limit in display units. (
Hb.ty ≠
Off)
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’

iP Input list - continued
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.
CAL.s Selected calibration point −
‘ nonE’, ’iP1.L’, ‘ip1.H’, ’iP2.L’,
‘ ip2.H’
AdJ * User calibration adjust, if CAL.s =
’ iP1.L’, ‘ip1.H’, ’iP2.L’, ‘ip2.H’
OFS.1 IP1 calibration offset
OFS.2 IP2 calibration offset
mV.1 IP1 measured value (at terminals)
mV.2 IP2 measured value (at
terminals), if DC input in Module 3
position
CJC.1 IP1 cold junction temp. reading
CJC.2 IP2 cold junction temp. reading
Li.1 IP1 linearised value
Li.2 IP2 linearised value
PV.SL Shows the currently selected PV
input - ‘
ip.1’ or ‘ip.2’
* Do not make adjustments using the AdJ
parameter unless you wish to change the
controller calibration.
