Control Loops (Single Set point Operation)
The loop view screens provide direct viewing options for the control and monitoring of the display control
loops. The loop screens allow the user to adjust the current loop set point (SP) and view the process
variables (PV) and percentages of output (%) for each loop.
Loop View
The loop view screen
is accessed from the home “View” menu. It can display from 1 to the maximum amount
of loops configured in the system. The screen provides loop control functions not available on the Overall
view screen. These functions are accessed by the Manual Control, Start and Halt control buttons.
The
left
and
right arrow buttons
allow you to switch between each loop in the system if more than one loop
is available. If the display is configured as a single loop system, the left and right arrow buttons will not be
shown.
The
loop name
, shown at the top right of the loop view, will update as each loop is shown. The unit display
field will update as well, in order to provide the user with the units of measurement for the selected loop.
The
set point entry field
is the area where the screen can be touched in order to bring up the keypad entry
window. Using the numeric entry keypad, a new set point can be entered. Once entered, the new set point
will be shown in the set point entry field. Adjustment of the set point is locked out if an automated ramp/soak
program is running.
IMPORTANT:
When operating in single set point mode, the set point is saved in the loop control board’s
memory once every 5 minutes. If the set point is changed and power is removed prior to the
5 minute time period, when power is re-applied, the loop set point will return to the previous
value. Make sure that power remains on the unit for 5 minutes after a set point change in
order to have it power-up with the desired set point the next time power is applied.
