Third, the characteristics of the control system

This machine uses: TH-1200C programmable 7 inch LCD color LCD display. System capacity: 120 sets of programs X100 segments, each set of programs required by the number of segments can be arbitrarily divided, each group of programs and can be freely linked to each other. Cycle setting: Each set of running procedures can be executed, 9999 back or numerous cycles repeatedly executed, and at that extent can be divided out of 5 stops to perform an additional part of the cycle. Operating mode: fixed value / program / link and other three modes of operation can meet the various temperature test conditions of the execution.

1. Control mode: intelligent microcomputer PID-SSR/SCR automatic positive and negative two-way synchronization output.

2. Data setting: built-in program directory management, facilitate the establishment of various test names and program data, change, consult or run lines.

3. Curve drawing: data set-up complete can immediately obtain the relevant data set curve, in operation can also be informed of the actual operation curve drawing picture.

4. Timing control: 2 sets of time series output control interface, with 10 time control modes, can be used by external logic drive components to perform start/stop timing planning.

5. Appointment start- all test conditions can set the function of appointment boot operation.

6. Operation lock: can lock the function conditions of start and stop, to prevent other personnel from touching by mistake and affect the experimental results.

7. Power outage re-return: with power-off memory device and re-start mode 1. BREAK (Disruption) 2.COLD (Cold Start) 3.HOT Hot Machine Start).

8. Safety inspection: built-in 15 full-featured system detection and perception devices to ensure the safe operation of the machine, when the perceived abnormal failure immediately cut off the control power of the machine, and automatically display the failure time, abnormal items and abnormal traceability: can show the historical data of abnormal failure.

9. External protection: an electronic over-temperature protection device independent of the controller.

10. Communication interface: RS-232 standard communication interface device, with personal computer (PC) at the same time online multi-machine control and management

11. Display switch: Chinese/English display subtitles, free to switch.
