CONTROLLING A PROFILE
Profile Start Operation
A profile always starts at the first ramp phase and the setpoint value ramps
from the current temperature value. The profile can be programmed to ramp
from a known setpoint value (see Ramp Phase section). Link-started profiles
use the last target setpoint level as the starting point. A profile is started from
the off 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 Profile Control Status Display
1. Verify the profile control status display (P-CS) is enabled in lockout
programming.
2. Profile must be in the off mode (no profiles running).
3. Press and hold “up” button for three seconds until “Pr-1” appears.
4. Select the desired profile by using the “up/down” buttons.
5. Press the “PAR” button to start the selected profile. The unit displays
“Strt” in the secondary display and starts the profile. If the “PAR”
button is not pressed within five seconds, no action is taken.
Start Operation From The Hidden Mode
1. Verify profile access (PrAC) in the hidden mode is enabled in lockout
programming.
2. Profile must be in the off mode (no profiles running).
3. Press and hold the “PAR” button for three seconds to enter the
hidden mode.
4. Scroll to “Prun” (if necessary) by pressing the “PAR” button.
5. When “Prun” is displayed, use the “up/down” buttons to select the
desired profile (Pr-1, Pr-2, Pr-3, or Pr-4).
6. Press the “PAR” button to start the selected profile. The unit displays
“End” in the secondary display and starts the profile. If a selection is
not made within ten seconds, no action is taken.
Start Operation Using The User Input
The user input can only start profile #1.
User Input Selected For Run/Stop (P1rS):
A low to high transition at terminal # 7 always starts profile 1.
User Input Selected For Run/Pause (P1rH):
A low to high transition at terminal # 7 starts profile 1, if no profiles
are in the pause mode.
Note: Refer to input module 1, user input section, for more details.
Start Operation On Power-Up
If power is interrupted or removed from the unit, the profile can be
programmed to automatically start when power is restored. In the Setpoint
Profiles Module (8-Pr), a profile can be programmed to automatically re-start
on power-up. The “Strt” option must selected for each profile (see power cycle
status parameter for details).
Start Operation Via The RS-485 Serial Option
Any profile can be started via the serial communications option. Transmit the
unit address, command letter with the value identifier and the desired profile
number via the serial port (see serial communication section for details).
Shown below is a typical command string.
