CONTROLLING A PROFILE
Profile Start Operation
A profile starts at the segment selected with the Starting Profile
Segment parameter,
PSg
(factory setting is Segment 0). Link-started
profiles use the last used target setpoint level as the starting point. A
profile is started from the end mode, which places the controller into the
run mode. To re-start a running profile from the beginning, it is necessary
to first stop the profile.
Start Operation From The Controller Status Display (
S
)
1.Verify the Controller Status Line 2 parameter (
S
) and Starting Profile
parameter,
ProF
are enabled in Display Locks programming (set for
P
, or

).
2.If you are changing to a different profile, navigate to the Starting Profile
parameter,
ProF
and select the profile you wish to run, using the up/
down keys. Enter the selection with the P key.
3.Navigate to the
S
display and select run using the “up/down” buttons.
Enter the selection with the P key to start the profile.
Start Operation Using the User Input selected for Stop/Run (
S
)
A user input de-activation starts the profile that is selected in the
Starting Profile parameter,
Po
.
Start Operation at Power-Up
If power is interrupted or removed from the unit while controlling a
profile, the profile will re-start when power is restored.
Start Operation Via Serial Communications
Any profile can be started via MODBUS communications. See the
MODBUS frequently used register table.
Profile End/Stop Operation
A profile can be terminated in several different ways. It can end by
running to completion or it can end by a user input or function key
activation. When running to completion, the profile can configured to end
and control to the last setpoint (Profile Link parameter,
LN
# =

) or it
can configured to end and disable PID control (Profile Link parameter,
LN
# =
StP
).
End/Stop Operation from the Controller Status Display (
S
)
1.Verify the Controller Status line 2 parameter (
S
) is enabled for the
desired display loop in Display Locks programming (set for
SP
,
P
,or

).
2.Navigate to the r-S parameter and press the up/down keys to select
P
or
StP
, and press the P key to enter the selection and perform the
selected action.
End/Stop Operation at Power-Up
If power is interrupted or removed to the unit, the profile can be
programmed to automatically end when power is restored. In the
Setpoint Profiles Module (
Po
), each profile can be configured to the
desired end action. See Profile Power Cycle Status parameter for details.
Profile Advance Operation
Advancing a profile ends the currently active phase and begins the
next phase of the profile. The total run time of the profile is shortened by
using the advance operation. Profiles in the pause mode must have a
continue operation performed before an advance operation. The profile
can be advanced from the delay mode.
Profile Advance from the Controller Status Display (
S
)
1.Verify the Controller Status Line 2 parameter (
S
) is enabled in Display
Locks programming (set for
SP
,
P
, or

).
2.Navigate to the
S
display. Select
P
using the “up/down” buttons.
3.Press the P key to perform the profile advance action.
Profile Advance using the User Input selected for Advance (
P
)
A user input activation advances a running profile to the next segment.
