10.2 Remote control (Inputs/outputs) of LAMBDA peristaltic pump
| No. | Color | Description |
|---|---|---|
| 1 | yellow | (+) input remote speed control 0-10V *) |
| 2 | grey | step signal from stepping motor (0 and 12V) |
| 3 | green | earth, 0 V |
| 4 | brown | + 12 V |
| 5 | white | (+) input remote ON/OFF; 0V = ON, 3–12 V = OFF (this logic can be inversed on demand) |
| 6 | pink | earth, ground (GND) |
| 7 | red | RS 485 B (-) |
| 8 | blue | RS 485 A (+) |
*) (zero line connected to the contact no. 3)
Note: If you have a modified LAMBDA peristaltic pump with 4-20 mA control (instead of the standard 0-10 V) with cable item no. 4810-o, the connection is as follows:
- No. 1 (yellow) is the (+) input speed control 4 - 20 mA, positive pole
- No. 3 (green) is the earth, negative pole
