The options of level 7 are shown on figure 29, below.
STAT (State) - it allows the user to activate the programmable setpoint (ON),
disable the programmable setpoint (OFF) or to indefinitely suspend (SUSPENDED)
setpoint execution; in that case, the setpoint value remains stationary at the setpoint
value which was under development when the selection SUSPENDED was assigned
to parameter STAT. To reverte, enable the option (ON).
Before enabling the programmable setpoint one should program the setpoint
values (SP-1, SP-2,... SP-10), the elapsed times to reach those values (t1, t2,...t10)
and the number of times (L.C.) this setpoint sequence should be repeated. Note that
t1 is the time interval for the setpoint to develop from the local setpoint to the first
programmable setpoint SP-1; t2 is the time interval it takes to reach SP-2 starting
from SP-1, etc.
