【 】: Decrease / rerun key. In the Setting state, click or long press this key to decrease the Setting value.In the main screen state, long press this key for 3 seconds to restart the run.

【 】: Increase / lock screen key. In the Setting state, click or long press this key to increase the Setting value.In the main screen state, click this key to lock or unlock the screen.

LED indicator Defines

1. 【AT/F】indicator :The lamp will be on when the temperature unit is degree Fahrenheit .The lamp will flash in auto-tuning, it will flash. In other states, it will be off.

2. 【TIM】indicator: The lamp will be on when there is a timing Setting,it will flash in reservation timing, it will be off when no timing function.

3. 【OUT】indicator :The lamp will be on when there is heating output , otherwise it will be off.

4. 【LOC】indicator : The lamp will be on when the screen is locked, otherwise it will be off.

5.【SIN】indicator : Invalid reservation

6. 【ALM】indicator: The lamp will be on when there is temperature deviation alarm or abnormal temperature measurement.It will flash when there is temperature deviation alarm. Under normal condition, it will be off.

5. Operations and usages

1. Controller power on display

After all the display are on for about 3 seconds, PV area displays SV displays version number for about 1 second and then enters the normal display state.

2. Reference and Setting of temperature and time

1) No-timing function:

In the main screen state, click the【Set】to enter the temperature Setting state, the PV area displays prompt SP, and the SV area displays the temperature Setting value, which can be modified to the required Setting value through the【shift】,【increase】,【decrease】, then click the【Set】to exit the Setting state, and the Setting value will be saved automatically.

Timing function:

In the main screen state, click the【Set】to enter the temperature Setting state, the PV area displays the prompt SP, the SV area displays the temperature Setting value, and the modification method is the same as above; then click the 【Set】 to enter the time Setting state, the PV area displays the prompt ST, TIME area displays the time Setting value; then click【Set】to exit the Setting state, and the Setting value will be saved automatically.

When the Setting time is "0", it means continuous operation. When the Setting time is not "0", before the timing starts, if the timing direction is count-down, the TIME area will display the timing time; if the timing is count-up, the TIME area will display "0". When the timing starts, "indicator" will flash.When the time is up, the operation will end. The TIME area will display End, and the buzzer will beep for EST seconds (see 7. Parameter TABLE-1). At this time, long press the 【decrease】for 3 seconds, the operation can be restarted.

3.Reservation function(see7.Parameter TABLE-6)

When an reservation time is Set, heating operation is prohibited.

PC-D9000 type: In reservation timing,A indicator flashes, and the count-down TIME area displays the reservation running time.

PC-E9000: In reservation timing,TIM indicator flashes, and the count-down TIME area displays the reservation running time.

Abnormal temperature measurement alarm

If the PV area displays "----", it means that the temperature sensor is faulty or the temperature exceeds the measuring range or the controller itself is faulty. The controller will automatically disconnect the heating output, the buzzer will sound continuously and the alarm light will be on. Please check the temperature sensor and its wiring carefully.

5.Deviation over temperature alarm (see 7. Parameter TABLE-1)

When the upper deviation over temperature alarm occurs in process, the buzzer beeps, the alarm light is continuously on, and the heating output is disconnected.When the lower deviation over temperature, the alarm will occur and flash. If the over temperature alarm is generated due to changing the temperature Setting value, the alarm light will be on, but the buzzer will not sound.

6. Lock screen function.

Three screen locking modes are provided. See [7. Parameter TABLE-1] for details.

Password unlocking: In the lock screen state, click the 【increase】, the input password prompt PA is displayed in PV area, and the password is displayed in SV area. After entering the correct password, click the【Set】to unlock.

7. When the buzzer sounds, press any keys to silence.

Auto-tuning system

When the temperature control effect is not ideal, the system can be auto-tuning. There will be a large overshoot in the process of auto-tuning. Please take this factor into consideration before system auto-tuning.

In the running state and the main screen state, long press the 【shift】for 6 seconds to enter the system auto-tuning selection state. The PV area displays the auto-tuning prompt AT, and the SV area displays "0". You can click the 【increase】 or 【decrease】 to select the display "1", and then click the 【Set】to enter the system auto-tuning state. The AT light flashes. After the auto-tuning is completed, the AT light stops flashing The controller will get a better set of PID parameters and save them automatically. In the process of system auto-tuning, long press the【shift】for 6 seconds to stop the auto-tuning program.

In the process of system auto-tuning, if there is an over temperature alarm of upper deviation, the alarm light will not be on and the buzzer will not sound, but the alarm relay will be automatically disconnected. In the process of system auto-tuning, the【Set】 is invalid.

6.Seven The internal parameters of the temperature are seen and Set.

In the main screen state, long press the【Set】for 3 seconds, the password prompt LC will be displayed in PV area, and the password will be displayed in SV area.Modify the required password through【increase】,【decrease】 and 【shift】, and then click the 【Set】. If the password is incorrect, the instrument will automatically return to the main screen state. If the password is correct, enter the internal parameter setting state, and then click the【Set】to modify each parameter in turn. In this process, long press the【Set】for 3 seconds to exit this state, and the parameter value will be saved automatically. See the table below for details:
