Event outputs can be selected as an individual segment or after other segment types have completed such as ramps,
soaks, steps and loop.
Outputs must be assigned as event outputs in setpoint 2 and/or setpoint 3 control settings menu before EOP’s can be
used. See section on PID Module settings.
Once outputs are configured select the correct EOP status for program segment.
None
No event output.
2D
SP2 output de-energised to mark event.
2E
SP2 output energised to mark event.
3D
SP3 output de-energised to mark event.
2E
SP3 output energised to mark event.
2D 3D
Both SP2 and SP3 outputs de-energised to mark event.
2E 3D
SP2 output energised and SP3 output de-energised to mark the event.
2E 3E
Both SP2 and SP3 outputs energised to mark event.
2D 3E
SP2 output de-energised and SP3 output energised to mark the event.
Note:
Only valid options will be displayed on the menu for selection. If required option is not shown ensure that
SP2 and SP3 outputs are configured correctly.
Event outputs are a change of state of SP2 or/and SP3. This state will remain until another event output is used to reverse
it or the program is stopped.
Event inputs
When an event input is used, a program is held at that point until a signal to proceed is received via a logic program.
When the program is held awaiting an event input, the temperature (or other process value) is held constant until the input
is received.
The event input number should be selected to match the event input in the logic program.
Call
If the same profile is required as part of a number of programs, it can be saved as a program and called into another
program when required. By inserting a call segment and choosing the required program the profile section will be added.
This will be shown on the profile chart as a shaded section.
Called
program
Loop
The loop function will run the same profile a specified number of times (recycle count). E.g. If a program has a recycle
count of 5 the profile will run 6 times in total.
Only one loop can be used in a program.
Once the number of loops are completed an event output can be triggered, see notes on Event outputs.
