Sect. 1) Description of the controller operating modes
The controller features various different operating modes:
•
controller in STOP mode
the controller is in STOP mode when no cycle is being run. The lights next to the
ST
O
P
S
T
A
RT
and
buttons are both off. The controller simply measures the
temperature of the kiln and shows this on the “MAIN” display. This mode allows the
following to be performed
select the cycle (see section 3)
display the total time and energy consumed in the last cycle (see section 2)
immediately run the selected cycle or set the start time, by modifying the delay time
as required (see sections 5, 6, 7)
•
controller in RUN mode
the controller is in RUN mode when a firing cycle is in progress, that is, when the
controller is controlling the temperature of the kiln according to the data set in the
cycle. In this mode, the light next to the
ST
O
P
ST
A
RT
button is on. The PRG and STEP
displays indicate the cycle and step in progress. The group of lights
indicate whether, in the current step, the temperature is increasing (heating),
stabilising or decreasing (cooling).
The energy consumed and the time elapsed since the start of the RUN can be
checked in this mode, including any pauses if the kiln cannot follow the required
temperatures. The cycle can be moved forwards or backwards to a desired point.
Each pressing of the
button moves forward one minute. Each pressing of the
button moves back one minute. When the cycle is finished, the controller
shows the message “END” on the “MAIN” display. To return to STOP mode, simply
press the
ST
O
P
S
T
A
RT
button.
•
controller in RECOVERY mode
the controller goes into RECOVERY mode when a cycle is interrupted by a
blackout. When mains power returns, the controller performs an extra step at a fixed
gradient (defined by the installer) to return to the setpoint prior to the blackout, and
then continues the affected cycle. This condition is signalled by the blinking of the
ST
O
P
S
T
A
RT
light, and the message “r” on the “STEP” display.
