Programmer
‘
TM.CFG’ = ‘ProG
’.
Function code CP is an eight segment programmer consisting of four ramp/dwell pairs. Each ramp
consists of a controlled rate of change of setpoint to a target level. Each ramp is followed by a dwell at that level. The
ramp rate, target level and dwell time are set by the user. The program profile is shown in the diagram below.
Notes:-
1.
When a step change is required, the ramp rate
should be set to ‘OFF’.
2.
Where ramp/dwell pairs are not required, the ramp
rate should be set to ‘OFF’ and the target setpoint,
TSP, the same as the preceding segment
3.
TIMER END - when the end type is SP2, Timer END
does not occur until the ramp is complete or SP2 is
achieved. It is more usual to use a DWELL (default)
or RESET end type
A single program event output is also available. To use
this refer to section 13.2.3.
