A 1000—1500 ohm resistor must be connected in 3. Thermal switches with CLS series with the thermal overtemperature switches. The CLS sensor is diode protected. For this reason A 1000 ohm resistor is enclosed in the package. the pilot cores are required to be connected with the correct polarity (brown = +, black = –). - Page 4 Part no. 6046800 frequency drive (VFD) may cause nuisance tripping of Will fit: 3102, 3127, 4430. monitoring equipment and the electronic sensor CLS. Part no. 6046801 Will fit: 3085, 4410. VFD-interference does not affect FLS and FLS10.

- Page 7 A leakage alarm may be caused by a short circuit due to pinched sensor leads or a correct leakage signal from FLS, FLS10 or CLS. Checking earth faults Earth faults on the monitoring cores must be checked for and avoided as they may cause spurious seal leakage indications.
- Page 8 Checking the MiniCASII Simulating normal condition The MiniCASII can be checked by using loose sen- sors connected to the sensor output or by simulating Connect a resistor of between 1 kohm to 1,5 kohm to the sensors using resistors. the 12 VDC sensor outputs 5 and 7.

TECHNICAL DATA MiniCAS II supervision relay Operational principle: Current Sensing Approvals: CE, C-UR (covering USA and Canada) Environment: –25 to 60°C (maximum 90% relative humidity) Supply voltage: 20-30 VAC (50–60Hz) 23.5–30VDC Relay contact rating: 250 VAC / 5A Voltage to sensor: 12 VDC +/–5% Values of operation: 3mA <... - Page 10 Mini- CASII. It is recommended if FLS10 in inspection chamber or CLS is used. These sensors detect liquid in the in- spection chamber (FLS10) and water in the oil (CLS), which is less critical than water in the stator housing.
