1 INTRODUCTION
The model 640 Securiterre is a grounding system for loading gantries that offers improved
safety during the transfer of flammable liquids or powders. It ensures that reliable grounding
has been achieved before any product transfer takes place. It is an indispensable item for
every loading facility of flammable non-conducting liquids and powders.
The Securiterre can be used for the grounding of trucks, trains or barrels.
Please note that the device can only be used in one predefined application. The device has
been configured to your specific requirements in our factory.
Safe execution of the procedures described in this manual requires technical skill in the
handling of tools and knowledge of safety regulations for working in hazardous areas.
The grounding clamp, the cable glands and the cable are not supplied by ALMA with
the Securiterre grounding system.
2 PRESENTATION
Before any power is applied to the Securiterre 640 check the following:
 Place clamp in rest position / rest plug
 Apply power and check whether the yellow LEDs light as should be. See the section that
follows for more indication.
Note: The magnet is not supplied by ALMA with the Securiterre grounding system

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
LEDs
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
LEDs
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

Highly sensitive, the Securiterre device will detect even small changes in grounding
properties as a result of weather conditions, loading equipment or any other grounding
sources that do not impact safety and in rare cases prevent the system switching to green.
If, after double checking the grounding, the release remains blocked, the magnetic
override can be used to reset the alarm as following:
• Connect the earth clamp to the earth point of the truck, the LED indication in this
case should remain red.
• Briefly place the brine magnet on the red dot located on the
top side of the Securiterre, see figure below. The instrument
should now respond within a couple of seconds indicating
successful grounding, do not remove the clamp during use
of the brine magnet. Remove the magnet after successful
grounding.
• Secondary connections, such as overfill alarms, filling attachments, etc., can now be
connected to the truck.
• After filling 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.
5 TRAINS APPLICATION
 Connect the earth clamp to the earth point of the train, 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 train.
 After filling 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: To achieve correct grounding conditions the cable clamp must be properly connected. If
there is no release after a few seconds (red LEDs are on), check the earth connection which
should be clean and free from corrosion.
Use of brine-magnet is not possible.
6 BARRELS APPLICATION
 Connect the earth clamp to the earth point of the barrel, 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
filling attachments, etc., can be connected to the barrel.
 After filling first disconnect the secondary connections such as filling attachments, etc.
 Then remove the earth clamp and place this back on the clamp holder.
Note: To achieve correct grounding conditions the cable clamp must be properly connected. If
there is no release after a few seconds (red LEDs are on), check the earth connection which
should be clean and free from corrosion.
Use of brine-magnet is not possible.
