MAM-890 screw machine controller is a new generation of high-tech productsdeveloped. The controller to micro controller as the core element has 2 switchquantity input, analog input,

2, 3 way switch quantity output (relay), Chinese liquid crystal display (4*8Chinese characters per screen), S485 network communication. Phasepreservation of function, the user can set the parameters according to the actual situation of the user. Equipment

Host computer control software, remote monitoring. Our technical staff according to user needs to be improved to better service to the user of the product.

Integrated function controller and instructions:

1, the switch quantity: 2 switch input, 2, 3 relay switch output.

2, analog: a Pt100 temperature input, a 4 ~ 20mA pressure signal input, a group of three-phase current input (CT).

3, the controller working power supply: AC20V, 20VA.

4, display range

①, exhaust temperature: -50 ℃ ~ 150 ℃; precision: ± 1 ℃.

②, run time: 0 ~ 999999 hours.

Third, the current display range: 0 ~ 999.9A.

④, pressure: 0 ~ 1.60MPa. Accuracy; 0.01Mpa.

5, motor protection: the controller has phase lack, unbalanced, the function of overload protection of motor,

First, the lack of protection: when any one phase power phase, the action time is equal to the set time; when open phase protection time is set more than 20 seconds, the lack of protection does not work.

②, unbalance protection: any of the two phase current ratio is larger than theimbalance, the action time is 5 seconds.

The characteristic inverse time protection, overload (for the second time unit),see the following table (table 2.1.1). Multiple = I / I set, when the overload ratio and action time delay action operation of the motor current is greater than or equal to the set current 1.2 times to 3 times the following table

6, temperature protection: when the actual temperature detected is greater than the preset temperature, action time ≤ 2s.

7, output relay contact capacity: 250V, 5A; the contact life 500000 times.

8, the current display error less than 1.0%.

9, RS485 communication interface, can be based on user settings, and other air compressor control operation, or press the MODBUS RTU protocol, as thecommunication with external equipment machine, from machine, baud rate 9600Bps, 1 start bit, 8 data bits, 1 stop bits, parity check.

10, the remote start stop air compressor: start stop mode set to the remote,users can remote switch, start and stop of air compressor.
