Ⅰ.General introduction
First of all thank you for using our meter, This manual contains instructions for the installation of meters, operations, parameter setting in the PC.
AQZ Rail Type Temperature Transmitter is a new type of meter that our Company recently developed, using photoelectric isolation technology, SMT manufacturing process and international standards Din Rail Installation, and have a wide voltage, small size, long life, easy-to-install, and strong anti-interference, and other advantages. Instrumentation is for a group of signal input, two groups simultaneous signal output, communication using ModBus agreement, through RS-485 interface with the PC or PLC-controlled part on-line to concentrate on monitoring and control meters, in connection with the PC Meter can amend the parameters through PC.

Ⅳ. Code setting mode
| Series | code | Name | Remark | Setting range | Ex-Factory |
| 1 | Pb | Sensor erroramendment | The sensor have deviation can use itemto revisal | 0～±20.0 | 0.0 |
| 2 | FILT | Filt modulus | The first order lag filter coefficient, the value is greater, the performance anti-jamming moment is stronger, but the response time lag. The pressure and flow control of its value should be smaller, temperature and level control should be relatively large | 0～50 | 20 |
| 3 | OUTH | Allow exportsmax value | Restrain maximum value of adjust output. | outL～2200 | 2000 |
| 4 | OUTL | Allow exports min value | Restrain minimum value of adjust output | 0～outH | 400 |
| 5 | LocK | Code lock | 0-all the parameter can be revised1-only the SP can be revised | 0～50 | 0 |
| 6 | Sn | Input type | ‘0’Cu50 –50.0～150.0℃； ‘1’Pt100 –199.9～200.0℃；‘2’Pt100 –199.9～600.0℃； ‘3’K -30.0～1300℃；‘4’E -30.0～700.0℃ ； ‘5’ J -30.0～900.0℃； ‘6’T -199.9～400.0℃； ‘7’ S -30～1600℃； ‘8’ R -30.0～1700.0℃； ‘9’ WR25 -30.0～2300.0℃； ‘10’ N -30.0～1200.0℃； ‘11’ Idiosyncratic type ； ‘12’ 0～5V(0～10mA)； ‘13’ 1～5V(4～20mA) | 0～13 | random |
| 7 | P-SH | Display the high limit | P-SH decide the display range, the value and unit are decided by factory and client freely. | P-SL～9999 | random |
| 8 | P-SL | Display the low limit | P-SL decide the display range, the value and unit are decided by factory and client freely. | -1999～P-SH | random |
| 9 | Addr | Communication addres | The meter’s number in the control system | 0～63 | 0 |
| 10 | BAud | Communication baud rate | ‘0’1200；‘1’2400； ‘2’4800； ‘3’9600 | 0～3 | 9600 |
When the meter connect the PC hrough the RS-485, it can amend meter parameters through the PC, parameters order please refer to Table 4-1. The default address for its communications “0″, the baud rate for “9600″. To connect multiple meters, the PC software address amend for “0″, baud rate changed to “9600″, at this time connecting on a meter, the menu address parameters will be changed to other numerical parameters (not larger than 63), after editing and then another meter to amend the address. Each meter is the only address, can not be repeated. And so on until the end of amending the connecting instrument.Ⅴ.Meter communications and parameters amending
Note: When the meter amended the address, the address numerical value labeled best on the meter avoiding confusion. PC software use refers to the help function in PC software.
4～20mA or 0～10mA linearity current input can achieve by changing 250Ω or 500Ωresistance to 1～5V or 0～5V voltage signal，and then input from A2、28 terminal.
Ⅵ. Fault Analysis and Clearance
Safety fence adopt advanced production process, and have the strict test before leaving factory, it improve the reliability of the meter .The usual fault caused by the wrong operation or parameter setting .If you find the fault couldn’t be cope with, please record it,and contact with the agent or us. Sheet 6-1 is the usual fault of Safety fence in the daily application：
Sheet 6-1 Common fault handling
| fault symptom | analysis of causes | Disposal measurement |
| Abnormal power | 1、Poor contact of power cord 2、Power switch without lose | Check the power |
| PC display do not correlate with the facts.（display‘FF’） | 1、Sensor model mismatch 2、Wrong signal connection | 1、Check sensor model and meter interior input parameter 2、check signal wire 3、Check communication wire |
| Abnormal output | 1、Wrong connecting output wire | 1、Check output connection 2、Check parameter OUTH、OUTL |
