On-off control mode , or PID control with the function of parameter auto tuning.
5. Output: SSR 5VDC/30mA output ,Relay contact output ,open normally
6. Alarm function: High Alarm, Lower limit alarm,Deviation High Alarm.
7. Power supply voltage rating: 100-240VAC, -15%, +10% / 50-60Hz.
8. Power consumption: ≤3W.
9. Ambient temperature: -10~+60℃, Humidity: 0~90RH%
IV. Basic display status
1.Change given Set Value:
When powered on, it shows the basic display status, upper window displays real
process value (PV) while lower window displays the set value (SV). If the real
value overruns measure range(thermocouple breaks for example), upper window
will display "orAL" and the highest and lowest values, at this time, controller will
automatically stop controlling the output.
In controller's face, basically there are 6~10 LED lights,OP1,AU1,AU2,RUN which
respectively stand for output, fi rst alarm, second alarm, and working condition.
2.Change SV setting
In basal display status, if the parameter lock "Loc" isn't locked, we can set setpoint
(SV) by pressing
、 、
. Press key to decrease the value,
key to increase the value, and
key to move to the digit expected to modify. Max
parameter of SPL and SPH, is limited to be 0~400C.
3 AI artifi cial intelligence control and auto tuning:
When AI artifi cial intelligence control method is chosen , the PID parameters can be
obtained by running auto-tuning. In basal display status, press
for 2 seconds,
the "At" parameter will appear. Press
to active the auto-tuning process. During
auto tuning, the instrument executes on-off control. After 2-3 times of on-off action,
the instrument will obtain the optimal control parameter value. If you want to escape
from auto tuning status, press and hold the
key for about 2 seconds until the "At"
parameter appear again. Change "At" from "on" to "oFF", press
to confi rm, then
the auto tuning process will be cancelled.
Note1 : AI-218 is with advanced PID, which makes it high accuracy.
Note2: If the setpoint is different, the parameters obtained from auto-tuning are
possible different. So you'd better set setpoint to an often-used value or middle
value first, and then start auto-tuning. Depending on the system, the auto-
tuning time can be from several seconds to several hours.
Note3: Setting of CHYS may have influence on AT.. The lower value of CHYS the
higher accuracy. But too low CHYS isn't advice, CHYS=2.0 is advice.
Note4: At the beginning after AT, the result maybe not table but it will get best result
after a time.
2 seconds auto tuning
V. Parameter Setting:
In basal display status, press and hold for about 2 seconds can access Field Parameter
Table. Pressing
can go to the next parameter; pressing 、 、 can
modify a parameter. Press and hold
can return to the preceding parameter. Press
(don't release) and then press key simultaneously can escape from the
parameter table. The instrument will escape auomatically from the parameter table if
no key is pressed within 30 seconds. Setting Loc=808 and then press
can access
System Parameter Table.

Small value can improve control

For SSR output, generally 0.5 to 3.0
seconds.
For Relay output, generally 15~40
seconds, because small value will cause
the frequent On-Off of mechanical
switch and shorten its service life. CtI
is recommended to be 1/4 ~ 1/10 of
derivative time. When control under
on-off control,Ctl use as restart delay

The value of FILt will determine the
ability of fi ltering noise.
If great interference exists, then you
can increase parameter "FILt" gradually
to make momentary fluctuation of

When the instrument is being
metrological verified, "FILt" s can be
set to 0 or 1 to shorten the response
