Installing a replacement limit indicator
Installing a replacement limit indicator without insert is only possible if the existing insert and
the existing tank panel / tank flange, respectively, including the related attachment parts, is
capable of supporting the probe tube with an outside diameter of 10mm. The adjusting
dimension
X
can be found in the hitherto, present assembly manual of the GWG or tank
manufacturer and must be set accordingly.
Install the insert according to its assembly manual.
Installation of the limit indicator to the tank
The following must be observed when installing the limit indicator
•
The probe tube of the limit indicator may not be cut to length or bent in any case. The cable
inside the probe tube may be damaged otherwise.
Install the limit indicator with a suitable probe length.
•
The limit indicator, the probe tube or the sensor may not be covered inside the tank, i.e.
installation in a protective or calibration tube not admissible.
At level
L
1
, contact between medium and sensor could be impossible.
•
The sensor may not make contact with the operating medium splashing from the filling
tube, which would cause the filler valve on the road tanker to be closed prematurely. If the
filling tube is arranged in the lower third of the tank, the sensor being wetted prematurely
can be ruled out.
•
Always install the limit indicator in a perpendicular position.
•
The operating medium may not have any corrosive or chemical effect on the sensor, the
sensor cover and the probe tube.
Installation location and installation position
Regarding plastic or GRP battery
tank system, filled from the top,
the following must be observed:
•
Limit indicator is located on the
first tank, when looking in the
filling direction.
•
Install the connector near the
filling hole plug.
Installing a limit indicator with fix adjusting dimension, Z = X
Limit indicators with mounted wall fitting 905 and fix adjusting dimension are only suitable for
certain tank shapes. The adjusting dimension must match the specification of the tank
manufacturer. When the limit indicator is configured fixedly, the adjusting dimension
X
cannot
be changed.
Installation of the limit indicator to the tank

Prior to installation into the tank, re-check the adjusting dimension
X
and control dimension
Y
for correctness.
•
The installation location for the limit indicator regarding battery tanks according to DIN 6620
is shown in
table 1
in
figure 1a
and
figure 1b
.
