Example of a Loading Cycle with 2-Wire Sensors
NOTE: Symbol (any color) below means flashing Light Emitting
Diodes A solid circle means LED indicator are solid on. Icons
and compartments can also flash.
Top figure shows an 8-compartment truck with 8 dry 2-wire sensors
shown by means of 8 Green indicators in the bottom bar and second
sensor icon in the bottom left corner of the display. Two flashing
white LED indicators in the Top-Right bar and icon on the bottom left
corner of the display indicate that the ground connection is within
specification.(low impedance) The status of the permit output relay is
shown in the upper right corner by means of a icon
The second figure will appear as soon as one sensor becomes wet, in
this example sensor in compartment 3.
The indicator of the wet compartment (3) will be solid on and all
remaining dry sensors indicators will flash red to emphasis the non -
permit status of the monitor. Shown by the in the upper right corner
Also the compartment on the display will flash as well as the second
sensor icon on the bottom line of the display. The state of the permit
output relay will be shown as a cross in the right upper corner of the
display.
Assuming the monitor is not set to EN13922 and bypassing wet
sensors is permitted.
At this moment the function key can be used to accept and bypass
the wet sensor in compartment 3. Place the function key as shown in
the picture on the right at the middle bar.
The two blue heartbeat LED’s will be on for 3 seconds to indicate that
the monitor has validated the key and a key icon will be shown on the
top line of the display.
The monitor will resume monitoring the remaining dry sensors in
compartment 1,2,4,5,6,7 and 8. This will be indicated by the
corresponding green LED indicators. Compartment 3 on the display
will stop blinking and show the compartment as full. Two flashing
yellow indicators in the middle bar will indicate that the monitor is
partial bypassed. This is also indicated by the sensor icon in the top
left corner.
The status of the permit output relay will change from to
The last figure on this page shows the situation if sensor 5 becomes
wet in a bypassed situation. This is similar to the previous state
where the compartment 3 became wet. Same sequence should be
used to bypass also the wet sensor in compartment 5.
The above can be done till all sensors are wet.
Note. In some cases the sensor becomes dry when the loading has been interrupted. In this case the indicator will stay RED
When a bypassed probe becomes dry the corresponding indicator LED becomes orange
