Programmer Servo Mode and Power Cycling
The way in which the program starts when ‘Run’ is selected or after the power is turned off and on again, is
determined by the SERVO MODE parameter, as follows:-
SP
The program will start from the current
setpoint
value.
On recovery from power failure, the program will reset. It will require to be run again manually. The working
setpoint will revert to SP1 or SP2 (depending on which was selected) and the whole program is repeated.
PV
The program will start from the
measured temperature
.
On recovery from power failure, the program will reset. It will require to be run again manually, but it will start
at the value of the PV at the point when the programmer is run again.
SP.rb
The program will start from the current
setpoint
value.
On recovery from power failure, the program will automatically run at the
last
ramp rate from the
original
setpoint value (SP1 or SP2)
, see the sketches below.
PV.rb
The program will start from the
measured temperature
.
On recovery from power failure, the program will automatically run at the
last
ramp rate from the
current
measured temperature
, see the sketches below.
The behavior of the programmer following a power failure is shown graphically below for SERVO = SP.rb and
PV.rb:-
PV
Power
off
Power
on
The SP (and PV) returns at the
previously set ramp rate and the
complete Dwell period is repeated
PV
SP
Power
off
The SP (and PV)
resumes at the
previously set
ramp rate
