results in a decrease in the control output. Ex, heating control.
A=1,
direct action control mode. When this mode is selected, an increase in PV
results in an increase in the control output. Ex, cooling control.
B=0,
without the function of alarm suppressing at power on or setpoint changing.
B=1,
having the function of alarm suppressing at power on or setpoint changing.
Refers to the description in the latter text.
For AI-518P,
C=0,
When the instrument work as a program generator, the upper window displays
the program step;
C=1
, it displays PV ( measurement value).
D=0,
The unit of program time is minute;
D=1
, the unit is second.
For AI-518,
C=0,
The setpoint is restricted between LoAL and HIAL;
C=1
, no restriction on the
setpoint.
D=0,
Sends PV during retrasmission;
D=1
, Sends SV during retransmission.
E=0,
disable the function of sectional power restriction
E=1,
enable the function of sectional power restriction
F only works on A2/C3 dimension instrument which has a light bar.
F=0,
light bar indicates output value
F=1,
light bar indicates measurement value
G=0,
When alarm is triggered, the alarm symbol is alternatively displayed on the lower
