Scb
FILt
Input Shift
PV input filter
Parameter Scb is used to make input shift to
compensate the error produced by sensor or input
signal itself.
PV-after-compensation=
PV-before-compensation + Scb.
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.

INSTRUMENT INSTALLATION AND WIRING
Wiring graph for instruments with dimension 1/4 DIN; 1/8 DIN Vertical and Horizontal
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.

DISPLAY AND OPERATIONS
① Upper display window, displays PV,
parameter code, etc.
② Lower display window, displays SV,
parameter value, or alarm
③ Setup key, for accessing parameter
table and conforming parameter
modification.
④ Data shift key, and auto tuning.
⑤ Data decrease key
⑥ Data increase key
⑦ LED indicator. MAN, PRG, MIO,
COM, OP2, AL2, AU1 and AU2
Com indicators is non-applicable.
OP1 and AL1 will indicate I/O operation of the corresponding module.
Basic display status:
When power on, the upper display window of the instrument shows the process
value (PV), and the lower window shows the set-point (SV). This status is called
basic display status.
When the input signal is out of the measurable range (for example, the
thermocouple or RTD circuit is break, or input specification sets wrong), the upper
display window will alternately display “orAL” and the high limit or the low limit of PV,
and the instrument will automatically stop output. If the lower display window
alternately display “HIAL”, “LoAL”, “HdAL” or “LdAL”, it means high limit alarm, low
limit alarm, deviation high alarm, and deviation low alarm happening.

OPERATION DESCRIPTION
z Set Value Setting:
In basal display status, if the parameter lock “Loc” isn't locked, we can set
setpoint (SV) by pressing 、 or . Press key to decrease the
value, key to increase the value, and key to move to the digit expected
to modify. Keep pressing or , the speed of decreasing or inscreasing
value get quick. The range of setpoint is between the parameter SPL and SPH.
The default range is 0~400.
z 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
、 or 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.
● AI artificial intelligence control and auto tuning
When AI artificial intelligence control method is chosen (CtrL=APId), 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 change
the value of At from “oFF” to “on”, then 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 confirm, then the auto tuning process will be
cancelled.
Note 1: 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. For the ovens with good
heat preservation, the setpoint can be set at the highest applicable
temperature. Depending on the system, the auto-tuning time can be
from several seconds to several hours.
Note 2: Parameter Ctl (on-off differential, control hysteresis) has influence on the
accuracy of auto-tuning. Generally, the smaller the value of Ctl, the
higher the precision of auto tuning. But Ctl parameter value should be
large enough to prevent the instrument from error action around setpoint
due to the oscillation of input. Ctl is recommended to be 2.0.
Note 3: The 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 excellent control result will be obtained after a
period of time because of self-learning.
