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
°C/°F.
Integral T
ime (Reset T
ime):
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 T
ime (Rate T
ime):
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:
Input shift value
Temperature
measured by
sensor
Displayed
temperature
0 (without shift)
100°C 100°C
10 (of
fset by 10
°C) 100°C 110°C
–10 (of
fset by
–10°C)
100°C 90°C
This function can be used mainly for fine tuning compensation,
while
leaving the
set temperature unaf
fected. 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
°C/°
F in
units of 0.1
°C/°
F when a temperature resis
-
tance thermometer is used. The input shift function remains ef
fec-
tive even if pin 3 on the operating mode selector DIP switch
(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
°C/°
F in response to
in-5.
