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 set temperature (set
point), but it can also be set as an absolute value when the event
alarm mode is selected. Set the alarm value by using the up or down
key while
al
is displayed. The message is not displayed if the alarm
mode selector is set to position 0.
Proportional Band:
p
While
p
is displayed on the PV display, the proportional band (P
constant) can be changed using the up or down key. The new value
will be displayed on the SV display. The P constant can be set in a
range from 0.0
°
to 999.9
°
C/

F in units of 0.1
°
C/

F. The factory set-
ting is 40.0

F.
Integral Time (Reset Time):
i
The integral time (I constant) can be changed when the character
i
is displayed on the PV display. Use the up or down key to change the
I constant. The allowable range is from 0 to 3,999 seconds in units of
1 second. The factory 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. Use the up or down key to set or
change the D constant. The allowable range is from 0 to 3,999 sec-
onds in units of 1 second. The factory setting is 60 seconds.
Input Shift:
in-5
When pin 3 on the internal operating mode selector DIP 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 illustrated 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, as follows:

While
in-5
is displayed on the PV display, the input shift, the value
by which the measured temperature is shifted and displayed, can be
set and displayed on the SV display. The range in which the input
shift can be set differs depending on whether a thermocouple or
temperature resistance thermometer is used as the temperature
sensor. When a thermocouple is used, the allowable range is from
–999 to 9,999
°

F when a temperature resis-

(SW201) is changed to the OFF position after the input shift value
has been set. If the displayed temperature does not need to be
shifted, set 0
