If I2 is installed in MIO, then you can connect a switch between 14 and 16. As for AI-518, SV1/SV2 can be
changed. As for AI-518P, press for 0.3~1 second for run/Hold function. If press over 4 seconds, then it stops
working.
5.2.7 Working with computer
AI controller are able to work with computer if S, S4 is installed. AIDCS is developed specially for AI
controller to be used and controlled on computer. Both Chinese and English version are available. 1~200
units controllers are workable. RS232/RS485 changable. One computer with two communication interfaces
are workable with 100 units controllers. Diffferent communication addresses are needed. AI-485 AIBUS is
advised to be used with AI series instruments.
Computer AI series intruments upto 100units
6. Widely used control mode
6.1 on/off control/ alarming instruments
On/off control mode is the simpest way of control, used in low requirement cases or alarms.
If want regulation function, AI-518 is adviced. Install W1 OR L2,L4 in OUTP. So that to achieve the best
control result.
On/off control can be decided by dF parameter. AI controllers are needed to be set as: CtrL=0,oP1=0, CF.A
can be used for positive/negtive regulation.CF.A=0, OUT is heating function or low alarm. CF.A=1, OUT is
for cooling or high alarm. SV is for set point.
Sometimes it may need more than 2 alarms, there are high limit alarm,low limit alarm. Parameters are
HIAL,LoAL,dHAL,dLAL. Respectively there are AL1,AL2,AU1,AU2 lights on controller panel.By correctly
setting these parameters, you can reduce comsumption and save energy,raise the control accuracy.
6.2 Temperature tramsmission/ program give gernator
AI-518 can give any range current outputs, the transmission accuracy is 0.5. Thermocouple or RTD inputs,
and any current output,accuracy is 0.2. The parameter setting is as belows:
If CtrL=0(on/off control mode),oP1=1,2 or 4(current output), main output is current transmission output. Then
this unit is without regulation function, but with alarm and communication function.
Sn, choose thermocouple RTD input
dIL, transmittion high limit,unit is C
