Ramp/Soak control (Timer function 3, Timer function 4)
Timer function 3 and Timer function 4 can be used to link Set values 1 to 4 (SV1 to SV4) for
ramp/soak control. In addition, the repeat function can be used to execute repeated ramp/soak control.
If a power failure occurs while the timer time is elapsing, restart will take place from
SV1 (Timer time 00:00) when the power is restored.
Action of Timer function 3 and Timer function 4
When the power is turned on or STOP is switched to RUN, control always starts from Set value 1
(SV1) and ends at Set value 4 (SV4).
SV selection is invalid in Timer function 3 and Timer function 4.
Timer function 3: After the timer time of Set value 4 (SV4) elapses, control continues using SV4.
Timer function 4: After the timer time of Set value 4 (SV4) elapses, control stops.
