6.Operation instruction

6.1Display status

After power on, the instrument will conduct self-tuning, then enter measuring

and monitoring status automatically. PV window displays current measured

value, while SV window displays setting value; If “orAL” was displayed

alternately between PV and SV windows, it means input value exceeded measuring range (or sensors in open loop), or input setting is incorrect. When there was alarm output, SV window will alternately display characters related to the alarms:

HiAL(alarm for high limit),LoAL(Alarm for low limit), dHAL(alarm for plus deviation),dLAL(alarm for minus deviation).

6.2 View output value

Press “SET” key (no longer than 1 second), if SV window displays character “A”(for instance), it indicates automatic control mode, while if the displayed character is “M” (for instance: ), it indicates the manual control mode.

6.3 Automatic/Manual control switch

Press “«” key (no longer than 1 second), the temperature controller can

switch between automatic and manual control mode without interference to the operation. Under automatic control mode, RUN indicating light will off; and under manual control mode, RUN indicating light will on.

(remarks: if the running status of the function setting is “2: forbid manual mode”, above operation is invalid).

6.4 Value setting

When SV window displays setting value, press “ ” key (“ ” key) to increase (decrease) setting value. Press “«” key to move cursor to required numerical position. Keeping “ ” key or “ ” key to be pressed could increase or

decrease the value quickly.

6.5 Launch self-tuning function

When use the instrument for the first time, it’s a must to use the self-tuning

function of the instrument to determine control parameters (M50, P and t)

for an ideal control effect. Press “«” key for over 2 seconds, then the SV window will display characters “A” and “T” alternately, and the system will

enter self-tuning mode. When self-tuning, the temperature controller will conduct digital adjustment. After oscillation for 2 to 5 times, the instrument will automatically set the PID control parameters (parameters M50, P and T). After self-tuning, the system will return to PID automatic control mode.

During self-tuning, press “«” key for over 2 seconds to cancel self-tuning, then the characters “AT” displayed in SV window will disappear.

Attentions: for temperature controller which had run self-tuning before,

it’s a must to set parameter CtrL as “2” before launching another self-tuning (please refer to section “parameters setting and definition” in this manual

for detailed operation). The control parameter value will vary according to

setting temperature, therefore, it’s a must to run self-tuning with the most

frequently used setting value of the system. If the setting value often

changes, run self-tuning with the middle value of setting values.

6.8Parameters related to alarm output: “HiAL, LoAL, dHAL, dLAL、 dF, ALP, CF”

6.8.1Alarm parameters: "HiAL、LoAL、dHAL、dLAL". These parameters are for setting the alarm function of the instrument. When there is alarm condition, the system will output alarm signals to drive alarm relay to act (normally opened contact close/normally closed contact open), and alternately display the alarm reasons in the bottom screen. The alarm will be dismissed once the fault is fixed. Alarm conditions are as following:

HiAL: alarm when measured value is larger than HiAL (PV>HiAL).

LoAL: alarm when measured value is smaller than LoAL (PV＜LoAL).

dHAL: alarm when plus deviation is larger than dHAL (PV>SV+dHAL).

dLAL: alarm when minus deviation is smaller than dLAL (PV<SV-dLAL).

Generally, user don’t need 4 alarms in effect at the same time. For any

alarm not required, set it to the maximum value to avoid triggering it. For example, set HiAL=9999, LoAL=-1999, dHAL=9999, or dLAL=9999.

6.8.2 Defining parameter for alarm"ALP"

Table 3: defining alarm function

Above are part of common ALP setting. The setting range is 0 - 31. It defines the output position of 4 alarms -- HiAL、LoAL、dHAL、

dHAL. It’s defined by following formula:

ALP=A×1+B×2+C×4+D×8+E×16

When A=0, HiAL alarm is output by AL1;

When A=2, HiAL alarm is output by AL2;

When B=0, LoAL alarm is output by AL1;

When B=2, LoAL alarm is output by AL2;

When C=0, dHAL alarm is output by AL1;

When C=1, dHAL alarm is output by AL2;

When D=0, dHAL alarm is output by AL1;

When D=1, dHAL alarm is output by AL2;

When E=0, SV screen will display alternately the alarm symbols, enabling user to know the reasons for alarm quickly;

When E=1, SV screen won’t display alternately the alarm symbols

(except orAL)

Alarm for input exceed measurable range (orAL) could occur when there are improper sensor specification setting, input disconnected or short circuit. If such alarm occurred, the instrument will stop control, and keep the output value as stipulated by parameter oPL. No setting is needed for orAL.

6.8.3 Hysteresis Band (Dead Band) parameter "dF"

For avoiding alarm signals caused by input value fluctuation, and consequently malfunction, the instrument has return difference parameter dF (also called as non-sensitive zone, dead zone, or hysteresis). For example, the influence of dF parameter: assume HiAL value is 800 ℃, dF value is 2.0℃, then only when the measured temperature is larger than 802℃(HiAL+dF), the instrument enters HiAL alarm status. And only when the measured temperature is lesser than 798℃(HiAL-dF), the alarm will be dismissed.

6.8.4 Function parameter "CF"

Parameter CF is for selecting some system functions: when CF=2,

it’s heating control; when CF=3, it’s refrigeration control.

6.9Parameters related to input “ Sn, diP, diL, diH, DL, Sc” 6.9.1 Sensor type input “Sn”

Table 4: sensor input code and measuring range

6.9.2 Decimal point position “diP”

Decimal position “diP” is for selecting displaying accuracy. This setting is only

for display. The internal measuring accuracy is fixed to be 0.1℃. When diP=0, it means the temperature display accuracy is 1℃.

When diP=1, 2 or 3, it means the temperature display accuracy is 0.1℃. When the temperature display accuracy is set to be 0.1℃, while the measured temperature is lower than 1,000℃, the temperature will be displayed with accuracy 0.1℃; when the measured temperature is higher than 1,000℃, the temperature will be displayed with accuracy 1℃.

Changing diP parameter can only influence the display, there is no influence to the measuring accuracy.

6.9.3 Definition parameters "diH" and "diL" for linear input range

Linear input includes signals such as current: 0-20mV, 0-60mV;

voltage: 0-1V, 0-5V; resistance: 0-80Ω, 0-400Ω. The displaying value

range for the signals is -1999 - 9999 (decimal position could be set by diP). Parameters diH and diL are used to define the display range of linear input.

6.9.4 Filtering parameter “dL”

ITC-100 has in-built digital filtering system. When the displayed value is not stable due to input interference, use digital filtering to smooth it. dL=0-20, the larger the dL value, the measured value will be more stable, but respond will be more dull. When the instrument is interfered at field, gradually increase the dL value till the instant variation of measured value

is within 2-5 unit. When verifying the instrument, it’s a must to set dL as 0

to improve responding speed.

6.9.5 Amendment parameter “Sc”

Parameter “Sc” is for offset amendment for input to compensate the

deviation of sensor or input signal. For thermocouples, if there is deviation

at the cold compensation, use parameter “Sc” to amend.

For example, assume input signal is constant (500℃), and Sc value is

0.0℃, then the measured temperature is 500.0℃; while Sc value is 10.0℃, the measured temperature is 510.0℃. The default value of Sc is 0.

This parameter shouldn’t be amended unless there is need to calibrate

the measurement.

6.10 Parameters related to control output “oPI、oPL、oPH、CtrL”

6.10.1Output mode parameters "oPI", "oPL" and "oPH" are used for limiting output

oPI is the mode of main output signal; oPL and oPH are the output low limit and high limit respectively.

When oPI=0, main output mode is time proportioning output (professional

PID adjustment) or digital adjustment. Models with SSR, relay, and zero-crossing triggering silicon should set oPI=0.

When oPI=1, output mode is continuous output (for models with linear
