Alarm:
al
When
al
is displayed on the PV display, the alarm value for alarm
output can be set on the SV display. When the temperature exceeds
or falls below the set alarm value, the corresponding alarm output is
produced and the ALM indicator on the front panel lights. Usually,
the alarm value is set as a deviation from the main setting, but it can
also be set as an absolute value when the event alarm mode is se-
lected. Set the alarm value by using the Up and Down Keys while
al
is displayed. The message is not displayed if the alarm mode selec-
tor is set to position 0. Factory-set to upper-limit, alarm value

When pin 3 of the operating mode selector switch (SW201) is set to
the ON position, the input shift function can be used. This function is
used to shift the temperature display from the measured value by a
desired value, as shown by the examples in the following table:

This function can be used mainly for fine tuning compensation,
while leaving the set temperature unaffected. Select this function by
pressing the Display Key three times in display level 0.
Proportional Band:
p
When the character
p
is displayed on the PV display, the propor-
tional band (P constant) can be changed using the Up and Down
Keys. The new value will be displayed on the SV display. It can be
set in a range from 0.1

NOTICE:
The output value will change according to the differ-
ence between the set value and the present value when
the proportional band is changed during control operation.
If this difference is too great, a drastic change will result.
Always switch to the manual output mode before changing
the proportional band.
Integral Time (Reset Time):
i
When the character
i
is displayed on the PV display, the integral time
(I constant) can be changed using the Up and Down Keys. It can be
set in a range from 0 to 3,999 seconds in units of 1 second. The fac-
tory setting is 240 seconds.
Derivative Time (Rate Time):
d
The derivative time (D constant) can be changed when the charac-
ter
d
is displayed on the PV display using the Up and Down Keys. It
can be set in a range from 0 to 3,999 seconds in units of 1 second.
The factory setting is 40 seconds.
