8.3 SP

8.3.1 Normal SP and Multi SP

In this instrument, values can be registered for normal SP and 8
kinds of SPs (multi SP) assigned to No.1 to 8. There is a couple PID
for each SP and it automatically switches to the PID to be used in
interlock with the SP to be executed (except when remote SP is
executed. Section 8.6 of this chapter).

8.3.2 Multi SP Setting, Switching and Ramping

When “use of multi SP” is set to “Used,” setting of multi SP, up/down
rate values and switching of multi SP are enabled. “Use of multi SP”
is set to “Not used” at factory setting. Setting and switching with
surface keys are executed on Operation screen. Switching of multi
SP can be executed from surface key, external communication or DI
contact. Multi SP is switched using a surface key by changing the SP
No. displayed on SP No. display in

display on Operation

screen with the dial. Every time the dial is turned, the SP that
corresponds to the SP No. is displayed on lower display (conditions
for multi SP switching Section 8.6 of this chapter).
The action when multi SP is switched varies as shown in the table
below by the setting for up/down rate. During SP ramping, the
decimal point on SP No. display blinks for each display of normal SP,
multi SP, bias, emergency SP, multi SP switching, up/down rate and
output.

Multi SP
switching

Rate setting

Action

Up rate is not
equal to OFF

SP ramping is executed to the new
multi SP according to up rate value.

Switching to
multi SP
larger than
current SP

Up rate is equal
to OFF

SP immediately shifts to new multi SP.

Down rate is not
equal to OFF

SP ramping is executed to the new
multi SP according to Down rate value.

Switching to
multi SP
smaller than
current SP

Down rate is
equal to OFF

SP immediately shifts to new multi SP.

Switching
from multi SP
to normal SP

Current SP is maintained regardless of
rate setting (current SP is moved to
normal SP without change). However,
it immediately shifts to remote SP
when the optional remote SP is
enabled.

[Caution]

The maximum value for ramping time is approx. 1165 hours (approx.
69905 min.). If ramping time exceeds this, display



for about 2

seconds at the start of ramping and execute ramping at the maximum
ramping time.
