|
|
|
|
| |
1 | Measure voltage between terminal |
|
| V DC | Voltage should be in the range 14 to 33 V DC. | |||||||
| 5 and 6 |
|
|
| Check power supply. |
|
| |||||
|
|
|
|
|
|
|
|
| ||||
2 | Measure ripple voltage between |
|
| V AC | Voltage must not exceed 2 V AC. Check power | |||||||
| terminal 5 and 6 |
|
|
| supply. |
|
| |||||
|
|
|
|
|
|
|
|
| ||||
3 | Measure sensor excitation voltage |
|
|
| V DC | Voltage should be in the range 3.0 to 6.2 V DC | ||||||
| between terminal 7 and 10 |
|
|
| ||||||||
|
|
|
|
|
|
|
|
|
| |||
4 | Measure sensor excitation voltage |
|
| mV DC | Voltage should be in the range | |||||||
| between terminal 8 and 9 |
|
| |||||||||
|
|
|
|
|
|
|
|
|
| |||
5 | Measure current in supply lead to |
|
|
|
|
| Current should be in the range 4 to 20 mA and the | |||||
| terminal 5 |
|
|
| mA DC | same value as measured in point 6. If not the | ||||||
|
|
|
|
|
|
|
|
| amplifier may be defect. | |||
6 | Measure current in supply lead to |
|
|
|
|
| Current should be in the range 4 to 20 mA and the | |||||
| terminal 6 |
|
|
| mA DC | same value as measured in point 5. If not the | ||||||
|
|
|
|
|
|
|
|
| amplifier may be defect. | |||
7 | Measure sensor resistance with |
|
|
|
|
| If the resistance measured is less that 1 M Ohm the | |||||
| sensor cable unconnected |
|
|
|
|
| sensor is defect. |

|
|
|
|
| If the resistance measured is less than 1 K Ohm or | |||||
| with sensor cable unconnected |
|
|
|
|
| greater that 50 K Ohm the sensor is defect. | |||||

|
|
|
|
|
|
|
| ||
| Is the cable damaged? |
