Temperature Controller
METICOM TM10 Module
6. PID self-adjusting function
(when SuP=453 or 845)
The controller will start to learn the system after power up (the process temperature should be less than 90% of set point).
Once the controller finishes "learning" the system, it returns to a standard PID control with the heat PID values automatically
set.
7. Boost (speed up heating) function
(when boS=1)
In normal (auto PID) control mode (soft start process is over or terminated), press MODE key to activate the boost function.
For the next 15 seconds (or until you press the MODE key again, whichever is sooner), 20% is added to the controller
output (100% output or parameter Pub limited maximum).
Normal indicator flashes.
8. Parameters
8-1. General parameters
1) SV: Setting Value, full scale.
2) ALH: high deviation alarm value.
When present value > SV+ALH, the buzzer is beeping, and the output is shut off.
No alarm when power on or after modifying the setting until new alarm happens.
3) ALL: low deviation alarm value.
When present value < SV+ALL, the buzzer is beeping.
No alarm when power on or after modifying the setting until new alarm happens.
4) LCK: parameter setting lock.
0: Off; 1: On, all parameters cannot be changed;
11: On, all parameters cannot be changed except SV.
8-2. Engineer parameters 1
1) A-n: initial power output percent for manual control, 0~100%, used with parameter nSL.
Note: When A-n is effective, its value is auto-refreshed by latest manual output percent.
2) P: control proportional band, 1~999.
3) i: integral time, 0~999s.
4) d: differential time, 0~999s.
5) Pb: PV bias, -120~120. Sensor correction is made by adding Pb to measured value (PV).
6) AdS: ambient temperature (internal mainframe) high alarm value, temperature unit is same as parameter C-F setting.
When Ads=0, this function is off.
7) SuP: SV setting upper limit / AT target setting (see AT function) / PID self-adjusting (see Section 7), full scale.
SuP ≤ 900, the controller executes auto-tune function by making 80% of setting value as target.
SuP> 900, the controller executes auto-tune function by making setting value as target.
SuP = 453 or SuP = 845, PID self-adjusting function is on.
8) nSL: Manual/Auto control mode.
