Programming Notes
Programs can be created in Level 1 or Level 2 of the 3508 Controller.
For the P10 and P25, new programs can be created while the current program is
operating.
To avoid unwanted heating at the end of a program, set the controller setpoint
temperature to zero before operating a program.
All new unused programs show only 1 segment of type 'End'.
The minimum number of segments for a program is 2. The second being an 'End' type.
Ramp-to-setpoint control. To achieve this, create a two segment program. Set the first
segment type as 'Rate' or 'Time'. Set the second segment type 'End' type' Dwell'.
For the P10 and P25, programs can be linked together using a 'Call' segment. However,
a lower number program can not be called and a program can not be ended with a call
segment.
A program can be ended in four ways:
1. With 'End' segment set to S.OP the power to the elements is turned down to 0%,
no matter what the 'Setpoint' temperature is.
2. With 'End' segment set to 'Reset' and the 'Setpoint' temperature turned down to
zero, power to the elements will be 0%. To do this set the 'Setpoint' temperature
to the minimum possible. For type B thermocouples this will be below zero.
3. With the 'End' segment set to 'Reset'. The controller will try to reach and maintain
the 'Setpoint' temperature in place before the program started.
4. With the 'End' segment set to 'Dwell'. The controller will dwell at the 'PSP' of the
last segment ("RUN" indicator flashes), until it is reset.
To reduce the number of segments in a program, change the last required segment to
an 'End' type.
You will be asked to press
to cancel or
for OK.
To cancel all segments in a program, change the first segment to an 'End' type.
