7. The Program is divided into a flexible number of Segments each being a single time duration and containing details for each profiled setpoint The total number of segments available is 100 per program with a maximum of 600 for the Time to Target Programmer and 480 for the Ramp Rate programmer The 2704 programmer may store up to 20 programs as standard with up to 60 if purchased It is often necessary to switch external devices at particular times during the program Digital event outputs can be programmed to operate during those segments 4 1 1 Synchronous Programmer In a synchronous programmer all PSPs are run on a common timebase That is they all start at the same time and the time duration of a segment is the same for each PSP This is shown in Figure 6 1 Program 1 Segment N PV Segment 1 E Time I Profile i i Segment 1 Setpoint Target q l Profile Setpoint Profile Setpoint 3 z HEN EM Start Run 1h 2h 3h 4h 5h 6h 7h 8h Time 16 Up to 16 Digital Events for the program Figure 4 1 An Example of a Synchronous Setpoint Program 4 4 User Guide Part No HA026502 Issue 5 0 Dec 04 2704 Controller Programmer Configuration 4 1 2 Asynchronous Programmer In an asynchronous programmer up to three PSPs can be run with a different number of segments based on an independent t
