5.10 Program Status
While a program is running the home display shows 3 values:
Top:
Measured temperature
Centre: Program setpoint (PSP)
Bottom: Power output percentage
To see more detail:
Press page once to go to the program status page. The top and centre values from the
home page remain on the display. The lower half of the screen now shows:
Current program number (P10 and P25 only)
Current segment number
Time remaining for that segment
Further presses of the scroll key while a program is running will reveal additional
information:
Status. This can be changed to Hold, Reset or Run by pressing up or down .
Program setpoint (PSP)
Current Segment Type. Step and Call segments are instant, so are only flashed on the
screen, unless Holdback is operating on that segment.
Target Setpoint
Segment Rate
Cycles left
Program Time Left
Program hold with holdback
If a holdback value has been set (see "Programming") and the program goes into a hold
state, the green HLD indicator will flash, until the measured temperature catches up.
If while in this condition the program itself is put into hold by pressing the RUN/HLD button,
the "HLD" indicator will stop flashing and remain on with the "RUN" indicator. When the
program is started again by pressing the "RUN/HLD" button, the "HLD" indicator will flash
again if the measured temperature has not caught up with the program.
Programming note:
For P10 and P25 models you can create or change other programs while the current
program is running, go to operator Page 3.
5.11 Power Failure Recovery
If there is a power interruption to the controller during a program, when power is restored
the controller pauses the program, then ramps the temperature back up to the current
Program Setpoint (PSP) before continuing the program.
Power fail during ramp segments: The ramp rate will be that of the current ramp
segment.
Power fail during Dwell segments: The ramp rate will be that of the previous ramp
segment. If a previous ramp segment does not exist, then the dwell will continue at
the current measured temperature.
