Page 3: Introduction
The tank sensor is usually a 2 wire loop powered device that operates with 24VDC supplied from the FXL3. Hawker tank sensors include the MiniSonda, Flexicap and submersible pressure transmitters. Installation This manual should be read in its entirety before installation. -
Page 4: Cleaning And Maintenance
The controller is not intended to be fitted outdoors in direct sunlight or where power washing, rain or other liquid ingress, or chemical corrosion, may occur. The controller may be further installed inside a control panel or other protective housing if required. The maximum operating temperatures must be taken into consideration. - Page 5 keep low voltage signal cables away from hazardous voltage and high current cables. The FXL3 comes with several factory fitted cable glands attached; the user can fit additional glands if required, unused glands can be sealed to maintain the box integrity. Care should be taken not to damage the PCB if drilling the box.
- Page 6 Iout (TB5) Retransmission output mA current. This current output is linearly proportional to the value displayed on the LCD e.g. Tank Level. This current can be used to drive external equipment. The external load should require a mA current input and be low impedance. Multiple loads should be connected in series, see retransmission drive specification in data sheet for load resistance etc.

shield (not connected to earth) it can be connected to TB3 pin 4 (-mA). If using an externally powered device see its specific instructions regarding the screen connection. Relay Contacts Relay 1, 2, 3, 4 and Fault Relay (TB6, 7, 8, 9 and 10) Single pole changeover volt free contacts are provided to operate external equipment. -
Page 8: Program Mode
Before the FXL3 can be used some parameters have to be programmed by the user. In all cases this will be at least the tank empty, tank full, LCD low and LCD high values. Other options are configurable via the software menus, these are explained below. Program mode To enter program mode hold the M key for 3s. - Page 9 OPLo Use the UP & DOWN keys to adjust (fine tune) the low mA/Volts retransmission value. This value precisely calibrated at Hawker Electronics factory but the user can adjust if necessary. OPHi Use the UP & DOWN keys to adjust (fine tune) the high mA/Volts retransmission value. This value precisely calibrated at Hawker Electronics works but the user can adjust if necessary.
