The Sentinel Guard device can also be used to monitor the mains power supply. The device can be connected to the
same mains socket as the compressor or pumping station.
Should there be a power outage, the device will begin
the alarm procedure
. The status of the mains power supply monitoring can be seen in the first page of the LCD
screen. If the device is started without connecting the power connector, the screen will remain red and the power
supply monitoring will be disabled.
POWER FAILURE ALARM
The Sentinel Guard device can also be used to monitor water level.
The device will come with one water sensor in-
cluded.
The sensor can be connected to the water sensor socket, after which the W# indicator will be lit. If the indi-
cator is not lit even though the sensor is connected, the sensor might not be properly connected; reattach the sen-
sor. The sensor should be installed around 5 to 10 cm above the floating valve of the pump.
The sensor should not
be installed directly below the inlet pipe of the pumping station; instead, install is so that it is clear of major
splashes.
Should the sensor be covered in water, the device will begin the alarm procedure.
The sensor will most
likely get dirty during usage, and it can be cleaned by unscrewing the four Phillips screws and rubbing the circuit
board found inside with rubbing alcohol.
WATER SENSOR
By default, the Sentinel Guard is set to wait 2 minutes from the triggering of an alarm before sending alarm messa-
ges.
The delay can be changed with the command
“
Alarm xx
”
where xx is the alarm delay in seconds. For example,
the command
“
Alarm
30”
would change the alarm delay to 30 seconds.
CHANGING THE ALARM DELAY
The units of the pressure shown by the Sentinel Guard can be changed with a command. Changing the units to kPa
can be done with the command
“
Units kpa
”,
and changing the units to PSI can be done with the command
“
Units
psi
”.
CHANGING THE UNITS
The Sentinel Guard default settings can be changed when needed by SMS commands. Simply send a command mes-
sage to the device number to alter any setting needed. Press Info Button to check from the correct page that the
setting has been changed as intended.
