5—1 Chapter 5 Maintaining Your CS-L and Trouble- Shooting No maintenance is required. Both the sensor head and the sensor electronics are enclosed in sealed, splash proof housings. Important: Care must be exercised in handling the CS-L, especially the sensor head, which contains delicate optical components. Excessive shocks and vibrations should be avoided. Trouble-shooting Despite the fact that your CS-L is a very reliable instrument, there can be two circumstances where problems may occur. The following table lists some of these problems and their attempted solution. However, please do not hesitate to contact your nearest Scintrex office. See “Warranty and Repair” for the office nearest you. Problem Possible Cause Possible Solution No Larmor signal output The indication that the output CS-L is receiving power is glowing of the LED light. If the light is not glowing, and the power is supplied, then the cable may be damaged. Check that power is supplied by measuring the voltage at either the I/O connector (pin B positive, pin A negative) or the power BNC coaxial connector. P/N 763701 Rev. 1
Maintenance Larmor output (readings) are noisy 5—2 The power is not supplied to the sensor electronics. Power supply as measured at points indicated above is not in the range of 24V to 35V DC. Current supply not in range. Sensor head oriented in the active zone. Possible conditions as noted for no Larmor signal output. There are large spurious AC fields present. Excessive field gradients across sensor head. Ambient magnetic noise is low. Check power supply. Check power supply. Note, a lower supply voltage is insufficient for proper operation, while a higher supply voltage will result in excessive dissipation of the internal voltage regulators, and may cause permanent damage. The supply current after 15 minutes warm-up is in the range 0.5 A (ambient temperature close to 50°C) to 0.8A (ambient temperature close to -40°C). Refer to the Orienting the CS-L chapter. Refer to above solutions. Check for possible sources of local AC fields. Check for possible sources of gradients. Check Power supply and Orientation. If all of the above conditions are met and Larmor output continues to be either not present or noisy, contact customer service at Scintrex Limited. P/N 763701 Rev. 1
