P159 programmer will carry an UP-SOAK-DOWN temperature cycle
following settings.
A. START TEMPERATURE
B. UP RATE
C. SOAK TEMPERATURE
D. DOWN RATE
E. OFF TEMPERATURE
2.0 DIGITAL DISPLAY

A. START TEMPERATURE
Push the SET button. The START LED will come on and the display will
flash, showing the previously entered start temperature. If this is the
required value it is the only necessary to push the ENTER button. If a
different value is needed, push the SET button. The thousands digit will
flash and the SET button can be used to set this digit to the required
value. Push the ENTER button. The hundreds digit will now flash and
again use the SET button to get the required value. It is worth noting
that if the SET switch is held down then the digit will continuously go
from 0 to 9 and it can be released when the required number is shown.
It is preferable not to make the switch operations too rapidly. The tens
and units are set in the same manner.
After the units digit has been entered all four digits will flash. Check
that this value is correct and push ENTER. However if the value is
incorrect push RESET and the display will show all zeroes with the
thousands digit flashing and the start temperature can be corrected.
Do not enter a temperature greater than 1250oC.
B. UP RATE
When the correct value for the start temperature has been entered the
UP LED will come on the display will flash showing the previously
entered value for the up rate in degrees/hour. The SET and ENTER
buttons are used in the same way as above to give the required value,
but in this case the entry is limited to 3 digits with a maximum setting
of 999oC/hour.
3.0 DEFINITIONS

C. SOAK TEMPERATURE
After the up rate has been entered, the SOAK LED will come on and the
soak temperature is entered in exactly the same way as described above
for the start temperature.
Soak time
When the soak temperature has been entered the SOAK LED remains on
and the soak time can be entered. The entry is in hours and minutes
with a decimal point separating the two.
D. DOWN RATE
When the DOWN LED is on entry is made in the same way as for the up
rate.
E. OFF TEMPERATURE
When the OFF LED is on the entry is made in the same way as for the
start temperature.

Running the program
After the off temperature has been entered the display will show ‘run’.
Pushing the RUN button starts the program.
When the program is started the load will rise uncontrolled to the start
temperature. The up ramp will not start until the load temperature gets
within 15oC of the start temperature. During this phase the up LED will
be on and the display will flash between ‘Hold’ and the load
temperature. When the load gets within 15oC of the start temperature it
will ramp up at the set rate. The ‘Hold’ feature also applies during the up
ramp, so that if the setpoint exceeds the load temperature by 15oC or
more the up ramp will hold.
When the soak temperature is reached it will remain there for the set
time. During the soak time the display will flash between the load
temperature and the elapsed time. When the elapsed time is shown a
decimal point separates the hours and minutes. It will then ramp down
at the set rate until the off temperature setting is reached when it
switches off, which is shown by all LEDS being off.
Showing the setpoint value
During the temperature cycle, pushing the SP button displays the
setpoint temperature instead of the load temperature. Also the UP,
SOAK or DOWN LEDS will show which segment of the cycle is being
done. If it is required to terminate the program at any time, pushing the
RESET button shows ‘rst’ in the display and the RESET button must be
pushed again while this is being shown. The display will then show the
load temperature and all LEDS will be off.

4.0 INSTRUCTIONS
Repeating a program
When a program has been run it is quite simple to run the same program
again. Push the SET button and the start temperature will flash. Push the
ENTER button, the up rate will flash, push the Enter button again until all
settings have been re-entered and ‘run’ is displayed.
Open circuit and reserve thermocouple protection
If the temperature exceeds 1250oC the display will show ’HIGH’ and the
output will be off.
If the thermocouple is inadvertently reversed then as the load is heated
the displayed temperature will go down. It will then display ‘-tc’ to show
that the thermocouple is reversed. When the temperature reaches a
value of about 80oC the output is switched off and the display shows
‘HIGH’.
Proportional band setting
The proportional band can be set to ±10oC , ±20oC or ±40oC. This can only
be done when the instrument is in the off condition. Push the ENTER and
RUN buttons together. On release the display will show Pb10, Pb20 or
Pb40. Pushing the SET button will change the display between these
three. Push ENTER when the required is shown. The best control is
achieved by using the smallest value but if the controlled temperature
tends to swing either side of the setpoint then a higher proportional
band setting must be used.
Power fail operation
If the power fails during a program, then when the supply is restored the
program will continue from the segment it was in when the power failed.
