Ensure that the supply voltage is correct
. The voltage of the power source must match the value given on the name-
plate of the machine within the tolerances of ±10 %. Machines with a 230V plate can be used in 220V mains and
110V machines in the 120V grid.
The machine has been double sealed according to European standards. The power source has to be grounded.
To begin using the Sentinel device, connect it to a mains power socket using the provided cable.
Always connect the power supply provided to the Sentinel unit. The unit has a back
-
up battery as well, but it is only
intended as a back
-
up for pressure measurement and to send alarm messages in the event of power failure, and is
NOT a substitute for the mains power supply.
VOLTAGE & POWER SUPPLY
Sentinel Guard uses a Mini sized SIM card. The SIM card slot is found next to the LCD screen, under the T shaped co-
ver. To access the slot, unscrew the six screws holding the cover (see picture from below). The SIM card slot opens by
sliding it to the left and lifting it up.
Before inserting the SIM card into the Sentinel Guard, the PIN code lock must
be turned off.
This can be done by inserting the SIM card into a mobile phone and turning the PIN code lock off. After
inserting the SIM card into the Sentinel, put the T shaped cover back on top, and gently fasten the screws.
It is recommended to use subscription based SIM cards and not prepaid SIM cards. Prepaid SIM cards might run out
of credit or be closed down inconspicuously.
CONNECTORS
There are three different types of connectors in the Sentinel device: pressure, water, and power. The pressure con-
nectors and water sensor connector are located on the left side of Sentinel. The power supply connector is located
on the right side of Sentinel.
When connecting the power supply connector or the water sensor connector, push the connector to the socket, and
screw the threaded nut all the way in. The power and water sensor connectors have a groove and cannot be connec-
ted if misaligned. The power and water sensor connectors have protective covers that are meant to be used when
the connector is not in use.
