Easy Configuration by Joystick
For easy configuration at the installation
site (e.g. of the configurable control out-
puts K3, K4 and E2), the EUS-2 unit fea-
tures a unique joystick control. It is situ-
ated well accessible on the backside of
the front cover inside the units housing
and allows an intuitively configuration
with concurrent view to the graphic dis-
play.
3.7.
Reliable Ground Verification
The EUS-2 unit features continuously
grounding verification and the ability for
setting the grounding limit value exceed-
ing EN 13922 requirements. Grounding is
monitored reliable independent from
truck configuration:
Trucks with grounding lines di-
rectly connected to the chassis
(EN 13922)
Trucks with grounding verification
via recognition device
(‘ground bolt’)
With a strict grounding limit value, wear-
ing off or dirt at the plug and socket
connection will be noticed in time for pre-
ventive measures.

Control Outputs | Data Interface
Six control outputs enable advanced op-
tions for connecting the control unit ac-
cording to individual customer needs:
2 Contact Release Outputs
(redundant, potential-free,
intern monitored)
1 Electronic Release Output
2 Configurable Contact Outputs
1 Configurable Electronic Output
The serial data communication interface
eases process integration. Operational
state commands can be transmitted to
external process control systems. This al-
lows remote diagnosis and process visual-
isation.
The analysis of the different control sig-
nals enables to distinguish, whether a fill-
ing process got interrupted by a correcta-
ble error (e.g. missing vapour recovery
hose connection) or an actual overfilling.
3.9.
Extended Area of Application
The type of explosion protection makes
the control unit applicable to Gas Group
IIB for filling even pure Ethanol. Further-
more, with its extended temperature
range from -40 °C up to +60 °C, the device
provides reliable operation under extreme
climate conditions.
