PV：Normal mode：Present temp. Value
Level select mode：Parameter level 1~4
Parameter mode：Parameter name
SV：Normal mode：Setting value、Manual output percentage

(23)PID Control
1. Output control mode
Main : PID
Main : on/off
Main : PID
Main : on/off
2. Output heating &cooling control mode
Main :heating Aux. :cooling
Main :cooling Aux. :heating
Auxiliary output function assists main output function in avoiding
the temperature out of control. They have opposite modes to
control.
3. Alarm Hysteresis band :
The output cycle time is one of important factor in control.It's
necessary to evaluate the heating and cooling system effici-
ency to set the output cycle time.suggest that the output
cycle time >20sec in relay output. If the output cycle tim e=0,
it will be analog output mode for that the higher temperature
stability system is desired,and the time=1~19 are for voltage
output mode and lower stability system

and it 's avalible to set by user.
(12)Key Operation
1、Entry into level select mode and select level, and press
parameter mode.
2 、In parameter mode, press level key leave parameter mode to
Level select mode.
3、In setting mode, press level key for saving parameter and return to
parameter
mode.
1、Press set key enable set value.
2、In parameter mode, press set key for enable to set parameter.
3、In setting mode, press set key for saving parameter or setting
digit, and
return to parameter mode.
1、In level select mode,
press increment
2、In parameter mode,
press increment
3、In setting mode,
press increment
until high limit.
1、In level select mode, press decrement key to entry parameter mode
2、In parameter mode,
press decrement
3、In setting mode,
press decrement
until low limit,,

at the same time for 2 sec to start or stop self-tuning.
Press decrement key for 2 sec to start or stop control output.
Press increment key for 2 sec to start or stop manual output.
Press set key for 8 sec to set the pass word "0044" automatically
Press
to return to the head of level in parameter mode.
Press
for 2 sec to return to normal mode.
6. Differential Tim e : D
Range=0~250 units,1unit=0.1sec and 0 for disable.It's
avalible to set by user.
7. What is the "PID" Control?
"P" is proportional band and unit =
with the following equation:
P = [ ( SV - PV ) * 100 ] / proportional band
"D" is differential tim e and unit=0.1sec. If "D"=10,10*0.1=1
sec, it means that differential action will be executed once
per sec. The setting is smaller and the time is shorter and
the output percentage is fewer.
8. PID Value Self Tuning :
PID value self tuning has three types: The first is disable
for self tuning,the second is only once ,and the other is
every times after power on.
But it only will be executed by the following situations:
The setting value of heating system should be higher than
the present temperature for 45
value of cooling system should be lower than the present
tem perature for 45
or 85
is desired,it's necessary to start this one, to set value,and
to comfirm that the temperature range is enough to execute
it, then turn off the power supply and restart the instrum ent,
we will see the PID value and the flashing of decimal point
in the right-down horn.It will be shuted after changing value
during self tuning.
