ST-707 Rotations Control
regulator, in which the blow-in and fuel feeding proceeds automatically
according to the PID algorithm, oscillating around the temperature set by
the user. If the temperature unexpectedly rises by more than 5
o
C above
the set value, the so-called
supervision mode
will be activated.
Supervision mode –
this mode will activate automatically, if the
temperature in the operation cycle rises by more than 5
o
C above the set
value. In such a case, in order to reduce the temperature of circulating
water, the controller will change the PID regulation to manual settings
(according to the parameters in the installer's menu) and the following
message will be shown on the display:
"PID: SUPERVISION"
.
Extinguishment –
if the flue gas temperature drops below 37
o
C (preset
extinguishment threshold) and does not rise above this value for 30
seconds (preset extinguishment time), the regulator switches to the
extinguishment condition. In this state the blow-in and the feeder stop
working and the following message is shown on the display: "PID:
EXTINGUISHED".
II.2. Homepage
During normal operation of the regulator, the
main page
is visible on
the
graphic
display. Depending on the operation mode, one of the
following screens is displayed:
Pressing the
knob
of the
pulse generator
brings the user to the first
level menu. The first three menu options are shown on the display. Turn
the knob to move to subsequent options. Press the knob to select a given
function. Similar actions are made when changing parameters. To
introduce changes it is necessary to approve them by pressing the pulse
generator when the
APPROVE
message is shown. If the user does not
want to make any changes in a given function, they should press the
pulse generator when the
CANCEL
message is shown. To exit the menu
select the
exit
option.
