[DB600] General Instruction Manual MODE 3
- 83 -
5-5-3 Setting 8 parameters for each group
8 sets of the control related main parameters including SV for constant value operation can be set on this
instrument. They are registered as group No. 1 to 8. You can just select a group No. that contains desired
parameters and start operation immediately.
Settable parameters are listed below.
 SV for constant value operation (8 types)
 Event 1 to 4 (8 types)
 PID (8 types)
 Output limiter (8 types)
 Guaranty soak (8 types)
Note that a change made in the input type, unit, measuring range, linear scale, alarm event type, etc. may
change the setting range automatically.
 Setting 8 types of event
Set an event value. The event modes of event 1 to event 4 can be set individually, but the setting is
common in 8 types. Event mode can be set in MODE4.
 Setting 8 types of PID
Adjust manually beforehand to set the PID constant for 8 types. Auto tuning can also be executed (see the
section 6-5).
See the section 6-6 for PID control.
 Setting output limiter
Set the operation range (higher/lower limit) of output signal. The output limiter functions in conjunction with
PID in the same group. Also, it is effective in auto tuning and manual output operation.
This function is used to protect the load or improve controllability.
 Setting guaranty soak
This function is used to stop timing and perform constant value operation if a measured value (PV) is out
of the guaranty soak setting range for a setting value (SV) at the time of proceeding to the next step in
program operation. The next step will be taken when PV falls within the setting range.
Reference

If a set value is small, it may be passed before the next loading, preventing the
guaranty soak from functioning.

When the guaranty soak is active, a program stops at the last step and the step No.
blinks.
It is possible to proceed to the next step using program operation ADVANCE, but
the next step will be entered automatically when a deviation value is met.
