INSTRUMENT INSTALLATION AND WIRING
Wiring graph for instruments with dimension A, E or F
Note:The compensation wires for different kinds of thermocouple are different, and
should be directly connect to the terminals. Connecting the common wire between the
compensation wire and the terminals will cause measurement error.

Note: it is recommended to use the SCR power module,which includes a pair of SCRs and
diodes. Compared to TRIAC, it is more reliable and consumes less electricity
possible different. So you'd better set setpoint to an often-used value or
middle value first, and then start auto-tuning. For the ovens with good heat
preservation, the setpoint can be set at the highest applicable temperature. It
is forbidden to change SV during auto tuning. Depending on the system, the
auto-tuning time can be from several seconds to several hours.
Note 2:Parameter CHYS (on-off differential, control hysteresis) has influence on
the accuracy of auto-tuning. Generally, the smaller the value of CHYS, the
higher the precision of auto tuning. But CHYS parameter value should be
large enough to prevent the instrument from error action around setpoint due
to the oscillation of input. CHYS is recommended to be 2
℃
Note 3:AI series instrument has the function of self-learning. It is able to learn the
process while working. The control effect at the first run after auto tuning
is probably not perfect, but optimal control result will be obtained after a
period of time because of self-learning.

FILt
PV Input
filter
The value of FILt will determine the ability of filtering
noise.
When a large value is set, the measurement input is
stabilized but the response speed is slow.
Generally, if great interference exists, then you can
increase parameter “FILt” gradually to make momentary
fluctuation of measured value less than 2 to 5.
When the meter of the instrument is being examined at
laboratory, “FILt” should be set to 0 or 1 to short the
response time.

For instruments with dimension F, just clockwise
rotate the graph 90 degree and the terminal
