3 LEDS INDICATION
3.1 States of the Securiterre when on Truck, Train and Barrel mode
3.2 In case of trouble shooting for Truck, Train and Barrel mode
4 TRUCKS APPLICATION
4.1 Proposed procedure
• Place the earth clamp on the clamp holder to start calibration. The LEDs will light up
yellow when the calibration process is finished
• Connect the earth clamp to the earth point of the truck, the LED indication should
instantly turn to yellow and then to green indicating a safe situation. If the red LEDs
remain activated check the clamp for good connection
• When the green LEDs indicate a safe situation other secondary connections, such as
overfill alarms, filling attachments, etc., can be connected to the truck
• After loading first disconnect the secondary connections such as overfill alarms, filling
attachments, etc.
• Then remove the earth clamp and place this back on the clamp holder
Note: The Return point is a brass pin intended to calibrate the clamp. The user should
place the clamp on this pin when the clamp is not connected to the truck.
Note: To achieve correct grounding conditions the cable clamp must be properly
connected. If there is no release after few seconds (red LEDs are on), check the earth
connection which should be clean and free from corrosion.
4.2 Magnetic override

indication
State Conditions for reaching the state
Yellow Rest The clamp is in rest position
Red Idle The clamp is removed from rest pin
Yellow Detected The calibration process is in progress
Yellow + Green Prepare loading The calibration process is finished
Green Loading Safe situation

indication
Meaning
Yellow + Red
Auto-test failure: The Securiterre may work but needs
repair
Green + Red
Poor internal relay contact grounding: The Securiterre is
unusable and needs repair
Red
Make sure the earth connection is clean and free from
corrosion
