4、Connecting Instruction Attention

Power must be off before wiring,or else, electric shock may occur.

Do not touch terminal or other electric parts after wired,or else ,

electric shock may occur

(1)Check carefully and ensure wiring is correct according to the terminal

arrangement on the temperature controller.

(2)For thermal couple input, use correct compensation lead that matches the

thermal couple.

(3)For platinum resistance input, each lead resistance should be less than

5ohm,and three leads should have the same resistance.

(4)Input signal should not be connected to the heavy current within the same lead or cable.

(5)Shieled cable(single-point grounding)is effective in resistance static

induction noise.

(6)For power supplies, use a 600V insulated conductor with a

cross-sectional area greater than 1mm

Example 3:Temperature offset

Blank area: surface temperature

(practical application area)

Black area: T/C measure temperature

(actual heating area)

There is a temperature difference between blank area: surface temperature and T/C

measure temperature.Take the customer's equipment as an example, what the

customer needs is the actual surface temperature (the actual application area), which is

the blank area in thefigure above.And T/C can only be placed in the actual heating area,

which is the black area in the figure above.And there's some temperature error between them,

because T/C can't be measured on the surface, how do youdo that?

Assuming the customer's required surface temperature is between

100° 150° 200° please resolve

1.First the relation between surface temperature and T/C measure temperature are

following:

T/C measure temperature Surface temperature Relation

Temperature is higher than the actual 5°

Temperature is6°higher than the actual

Temperature is 7°higher than the actual

2.Using the PVOS three point complement function, set(TM=100°

TS=-5°），（TM2=150° TS=-6°),（TM3=200° TS= - 7°) ,

T/C measure temperature Surface temperature Relation

T/C temperature is 5°higher than the actual

T/C temperature is 6°higher than the actual

T/C temperature is 7°higher than the actual

Previous row: customer needs virtual

real temperature

Next row:T/C actual temperature

3.When SV is set to 100, control PV to 100

Although the actual heating temperature control zone

(T/C measured temperature) is 100+5=105°

However, the PV of 100° is the actual application area (surface temperature),

which meets the customer's requirements.

Note: TS is not positive when the above conditions are reversed

11. (AMG)MG900 Series MODUS Communication Protocol

1.Protocol Introduction

1.1 Scope of selection: pan-globe M2000 series communication instrument

1.2 Work realization: data exchange between instrument and host computer (instrument can only be used as slave to receive interrogation and reply)

1.3 Serial transmission mode: RTU

1.4 Transmission interface: RS485

1.5 Communication medium: shielded twisted pair

1.6 Communication stack number: 1~255. The upper limit of the number of connecting meters is related to the load capacity of the host

1.7 Function code implementation: read hold register (03), write single register (06), write multiple registers (10)

1.8 Data length: 1) when writing data to the machine, a maximum of 16 consecutive menus (32 bytes) can be written at one time.

2) when reading the menu data inside the machine, the non-programmed menu can read 16 consecutive menus at a time (the unrealized address

outside the parameter address table is 0), while the programmed menu can only read 16 consecutive menus at a time

1.9 Numerical format: signed 16-bit binary complement;The data read is 10.0 times larger;Before writing the data, enlarge the data 10.0 times

before sending it; Notice the transition

1.10 serial port parameters: 1), baud rate :4800, 9600, 19200, 38400, 76800, 153600 2) start position: 1 3) data bit: 8

4) check bit: E(even check), N(no check) 5) stop bits: 1, 2

1.11 Frame check method: cyclic redundancy check (CRC16)

1.12 Message format (N=2 here)

Address Function code Data CRC check

8 bits 8 bits N*8 bits 16 bits

Note:

1、 read AM and AM1(cold control manual) menus,0 represents manual state,1 represents automatic state.

2、 RAP is the program control menu, read, return 0X0000 represents the program control close, return 0X0001 represents the

program control start: write 0X0000 to close the program control, write 0X0001 to start the program control, write 0X0002 to stop the program control,

write 0X0002 to end the suspension, continue to run the program control.

3、 Before writing the program-controlled menu, please write 0x0000 to RAP to close the program-controlled menu.

4、 Before writing MV/MV1 threshold, please first write 0x0000 to AM/AM1 to make the system switch to manual control.

5、 When the multiplier is 10, the returned data is magnified 10 times.

6、PV1 and PV2 are read-only parameters.

7、There should be a time interval between write parameter instructions, no matter the same address or not, which may cause instrument failure, and the time
