SCK,SCK= Standard value / Measure value.
3) P for setting proportional band. When take place regular oscillation of controlled temperature, the
proportional band should be increased and if controlled temperature drifts irregularly we ought to
decrease the proportional band.
4) I for setting the integral time. When the system takes place regular oscillation ought to I for
setting proportional band. When take place regular oscillation of controlled temperature, the
proportional band should be increased and if controlled temperature drifts irregularly we ought to
decrease the proportional band. ncrease integral time and if the system controlled can not remove
the static deviation in a long time ought to decrease the integral time.
5) D for setting the derivative time. Increasing the derivative time can decrease the overshoot of the
system.
6) T is Control Period, Relay output ≮20s,SSR and thyristor output≮3s continuous output,1s.
7) AL1 is alarm value 1, Measure value giving an alarm after deflecting setting value ∣AL1∣℃,
AL1 is set up giving an alarm for being to reach the end point at 0，
Upper limit alarm for AL＞0,
low Limit alarm for AL＜0.
8) At the regular time function option parameter ET is 0，No regular time function，Time sets up a
menu concealing；ET is 1 or 2，Demonstrate time setting up menu ST. If ST is 0, Do not mind
time then, ET is 1, After the electricity on the instrument, Reckon by time beginning, ET is 2,
While the temperature reaches setting value start timing. Adopt countdown way at the regular
time, Begin to reckon by time，
the upper row displays the Remain in time value，
Reckon by time
being over, the upper row displays STOP，
Run stoppage，
Export a cutoff, Have intermittent buzz
sound prompting at the same time, Push down any key but noise reduction. After press start/stop
key over 3 seconds, Can start or stop procedure work.
9) dP is that the temperature is sure to change option , dP is 0 , temperature display has no point,
dP is 1 , temperature display has point.
10) Pr is Upper limit constant temperature power percentages, Generally, The function big or
preserving heat if systematic power allocation is prejudiced is very good, Pr value responds to
small, Can prevent from rushing the temperature; Whereas Pr value responds to then big, Can
improve litre of temperature speed. One system is different generally in different setting up under
the temperature from P , I , D parameter that adjust reaches, Suggest setting up temperature
adjusting parameter being able to reflect system inertia nearby in the room temperature, But be
used for the high temperature litre of temperature is possibly slower time end, Effect adjusting Pr
value now being ok to make system can reach very good controlling within entire range.
