Setup and Operation
P. 3
e-litro secu4:
The
secu4
device is an oil tank measuring system for battery tank systems. The complete set
consists of the displaying device and the sensorbox which has to be mounted close to the tank.
The sensorbox of the
secu4
has 4 measuring hose inputs to measure and observe 4 single tanks
of one tank-battery at the same time. In addition to the level indication (in liters, cm, %, refillable
clearance) the device also monitors the levels of every single tank to avoid an overfilling. If during
the tank filling the level of one of the tanks reaches its maximum, e.g. 95% filling limit, the
secu4
will sound the ALARM and an output relay will interrupt the current loop of the tanker.
The displaying device and the sensorbox both contain of an alarm sound.
Such an alarm can be switched off by pushing the QUIT-button on top of the displaying device.
In case of an alarm the QUIT-button will flash red.
Instead of connecting it to a 4-20mA sensor as usual the
secu4
has to be connected to the sen-
sorbox via three-pole clamping block on the left hand side of the circuit board:
secu4 data input
from the sensorbox:
clamp 1
= plus,
white
(or red)
clamp 2
= data,
green
(or blue)
clamp 3
= minus,
brown
(or black)
The data line from the sensorbox to the displaying device (three-pole) is prolongable up to 50m
The use of a current loop connection box is optional. Therewith the tank filling can be
interrupted automatically.
