SuperNova PD500 PID Process & Temperature Controllers
Instruction Manual
21
Controller Operation
The controller can accept thermocouple, RTD,
voltage, or current inputs (4-20 mA with an external
resistor). The temperature or process input is
displayed as the Process Value (PV), in engineering
units from -999 to 9999.
A second line displays the Set Value (SV). This is the
desired value the controller will maintain. This value
can display -999 to 9999.
The PD520 and PD530 have a third line, the
Manipulated Value (MV) or output value. This is the
percent full scale of the control outputs. The MV may
be displayed on the SV display of a PD510 by
pressing the MD key.
Controller Powers-On in STOP Mode
For safety reasons, the controller enters STOP mode
on power-up by default. To enter RUN mode and
enable the control outputs, press and hold the SHIFT
key for two seconds.
In STOP mode, the controller will not display the MV
output percent, and the control outputs will be off.
The power-on mode may be changed in the Power-
On Operation Mode (PO.OM) parameter in the
Settings Group (G.SET).
Change Control Set Value (SP)
The Set Value can be easily changed to a new control
set point by pressing the SET key, and using the UP,
DOWN, and SHIFT keys to enter the new set point.
When the new Set Value is entered, press the SET
key to confirm.
The front panel function keys are also used to change
between automatic and manual control modes and
lock the controller to prevent accidental changes.
RUN/STOP Modes
The controller has a RUN and STOP mode. Switching
between these modes is done by pressing the SHIFT
(PAUSE/LEFT arrow) key for two seconds, or by
using digital inputs.
In RUN mode, control outputs, SUB alarm outputs,
communication, and all other functions operate
normally. Auto-tuning can only begin while in run
mode.
In STOP mode, control output will operate at 0%, and
auto-tuning will not be possible. The MV display will
not appear when in STOP mode. Other functions will
behave normally.
Menu Timeout
If the controller is left in the programming menus or
changing a parameter or set value, it will return to the
normal run mode display in 30 seconds.
