4. You MUST scroll YES and use the 5. Now use the Right Button to scroll “Hidden” Button to confirm YES for all across to Alarm Trigger Points and screens Specific Gravity settings. 6. Now use the Right Button to scroll across to the Sensor Selection. This should be Automatic.
High Accuracy Calibration Adjustments. For fine tune Calibration, the sensor settings can be adjusted to suit the individual user. For Voltage Sensor. For Current Sensor. The Maximum Value can be adjusted up or The Zero Value can be adjusted up or down to down to suit.
Appendix 1 (C2020 Wiring Diagram) MAINS POWER SUPPLY Units are supplied with either 24vdc direct connection, or 100/240 Vac power supply. Power supply connections can Bund Alarm is an input for a be made by REMOVING the mechanical float switch Bund Alarm.
Appendix 2 (Accessories) B8 – Bund Probe / Level Switch The Bund Probe has an integral N/C (Normally Closed) level switch. The Sensor body is made from 304 Stainless Steel and the cap is 316 Stainless Steel. The float is NBR (Nitrile) which is good in Oil, Diesel, Petrol, most spirits and water based products (SG: 0.7 to 1.5).
