FRONT PANEL AND OPERATION

1. Upper display window, displays PV, or code of a parameter
2. Lower display window, displays SV, alarming code, or value of a parameter
3. Setup key, for accessing parameter tables, and confirming change
4. Data shift key, also for activating auto turning
5. Data decrease key
6. Date increase key
7. Indicator lamps: (OP1, AL1, AL2, AU1and AU2 indicate the I/O actions of the corresponding modules)
   Basal display status: When power on, the upper display window of the instrument shows the process value (PV). and the lower window shows the setpoint (SV).This status is called basic display status. When the input signal is out of the measurable range (for example, the thermocouple or RTD circuit is break, or input specification sets wrong), the upper display window will alternately display "orAL" and the high limit or the low limit of PV, and the instrument will automatically stop output.

OPERATION DESCRIPTION

• Setpoint Setting:
  In basic display status, if the parameter lock"Loc"isn't locked, we can set setpoint (SV) by pressing / or . Press key to decrease the value, key to increase the value, and key to move to the digit expected to modify. Keep pressing or , the speed of increasing or decreasing value gets quick. The range of setpoint is between the parameter SPL and SPH. The default range is 0 ~ 400 ℃.
• Parameter Setting
  In basal display status, Press and hold for about 2 seconds can access Field Parameter Table. Pressin can go to the next parameter; pressing / or can modify the ralue of a parameter. Press and hold can return to the preceding parameter. Press (don't release) and then press simultaneously can escape from the parameter table. The instrument will escape automatically from the parameter table if no key is pressed within 25 seconds. Setting Loc=808 and then press can access System Parameter Table.
• Artificial Intelligence control and auto tuning
  When AI PID control method is chosen (CtrL=APId), the PID parameters can be obtained by running auto-tuning. In basal display status, press for 2 seconds, the "At" parameter will appear. Press to change the value of "At" from "oFF" to "on", then press to active the auto-tuning process. During auto tuning, the instrument executes on-off control. After 2 cycles of on-off action, the instrument will obtain the values of PID parameter. If you want to escape from auto tuning status, press and hold for about 2 seconds until the "At" parameter appear again. Change "At" from "on" to "oFF", press to confirm, then the auto tuning process will be cancelled.

Note 1:
If the setpoint is different, the parameters obtained from auto-tuning are possible different. So you'd better set setpoint to an often-used value or middle value first, and then start auto-tuning. For the ovens with good heat preservation, the setpoint can be set at the highest applicable temperature. It is forbidden to change SV during auto tuning. Depending on the system, the auto-tuning time can be from several seconds to several hours.

Note 2:
Parameter CHYS (on-off differential, control hysteresis) has influence on the accuracy of auto-tuning. Generally, the smaller the value of CHYS, the higher the precision of auto tuning. But CHYS parameter value should be large enough to prevent the instrument from error action around setpoint due to the oscillation of input. CHYS is recommended to be 2℃

Note 3:
AI series instrument has the function of self-learning. It is able to learn the process while working. The control effect at the first run after auto tuning is probably not perfect, but optimal control result will be obtained after a period of time because of self-learning.

PARAMETERS AND SETTINGS

• Field parameter table (Press and hold for 2 seconds to access)
  
• System parameter table (set Loc=808 and then press to access)
  
  

INSTRUMENT INSTALLATION AND WIRING

Wiring graph for instruments with dimension A, E or F

Note:The compensation wires for different kinds of thermocouple are different, and should be directly connect to the terminals. Connecting the common wire between the compensation wire and the terminals will cause measurement error.

Note: The graph suits for upright intruments with dimension A or E.

For instruments with dimension F, just clockwise rotate the graph 90 degree and the terminal numbers keep the same.

Wiring graph for D dimension(72mmX72m) instruments

Wiring graph for D2 dimension (48mmX48mm) instruments

Wiring graph for Thyristor Trigger Output

Note: it is recommended to use the SCR power module, which includes a pair of SCRs and diodes. Compared to TRIAC, it is more reliable and consumes less electricity
