Delay start
Ramp soak can be automatically started (RUN) after a certain period of time has elapsed
since the power of the controller is turned on.
This function is enabled by setting the digital input function (DI n) and the digital output function
(DonT), and setting the delay time to set with dLYn.
The following steps will explain how to assign the delay start to DI 1, Do1 and to set the delay
time to five minutes.
PV start
When the ramp soak starts (RUN), this function searches the first point where the measure-
ment value (PV) and the program pattern match, and starts operation at that pooint.
If the measurement value does not match the pattern as with PV=
➂
, the normal operation
starts.
7-10
Digital Input Function
Each of the digital inputs (DI1 to DI3) can be assigned the following functions. The specified
function will run when an external DI signal enters the input.
The following steps will explain an example of how to set DI1 to switchover between standby
ON/OFF.

Caution
When “Switchover between local and remote” (DI setting value =3) is used for the
digital input function, the operation before turning off the power of the main unit
affects the DI operation when the power turns on again.
(For the DI operation when the power turns on under each state, see the table
below.)
