Programming the Controller
The following section defines the parameters in each
of the setup Group menus.
Set Value Group (G.SV)
The Set Value (SV) Group contains parameters used
to program a new Set Value, set limits on the Set
Value, or select from existing Set Values.
Set Value and Set Value Number
(SV.NO)
The active Set Value is the set point the controller will
attempt to maintain. There are four programmable Set
Values (SV1 to SV4).
The Set Value Number (SV.NO) parameter selects
which programable Set Value number, 1 to 4, is
active.
In addition to setting this parameter directly, digital
inputs may be used to select from SV1 and SV4 or
the remote Set Value input (REM).
The use of digital inputs and the remote SV input will
change the behavior of this parameter and selecting
which Set Value is used.
•
When the digital inputs are enabled the
digital input selection will take precedence
over the Set Value Number selected.
•
When the remote SV input (REM.E) is ON,
the set value number and programmed set
points will be ignored.
•
When both the digital inputs are enabled,
and the remote SV input is enabled, using
the digital inputs to select SV-4 will use the
REM input to select the Set Value.
SV-1 to SV-4 must be within the limits set by the SV
High Limit (SV-H) and SV Low Limit (SV-L)
parameters.
Set Value High Limit (SV-H) and Set
Value Low Limit (SV-L)
These may be used to prevent the setting of
unintentional Set Values. Both the selections of
SV.NO, as well as the REM SV are limited by these
parameters.
The Set Value High Limit (SV-H) will define the high
limit of the Set Value.
The Set Value Low Limit (SV-L) will define the low
limit of the Set Value.
Set Value 1, 2, 3, and 4 (SV-1, SV-2,
SV-3, SV-4)
SV-1, 2, 3, and 4 are the Set Values the controller will
try to maintain. Only one Set Value may be used at a
time by the controller.

1. Default value determined by the default unit of the selected input type.
2. The high and low SV limits are the high and low limit for the selected input type. FR.H/L is used when
thermocouple or RTD inputs are selected.
3. The high and low SV limits are the high and low limit for the selected input type. SL.H/L is used when mA,
VDC, or mVDC inputs are selected.
