NOTES
:
x
If the current pressure exceeds the device's nominal pressure, it can no longer
be displayed, and the display begins to flash.
If the actual pressure is below 0.6 % of the nominal range, 0 bar will be
displayed.
x
The accumulator pre-charge pressure, referred to in the following by p
0
, only
approximately corresponds with the real p
0
in the hydro accumulator.
Temperature dependencies and the design of the accumulator system can
cause reproducible deviation.
x
Please read the operating manual relevant for the used system!
x
Further information on hydro accumulators can be found in the following
brochure: HYDAC Accumulators No. 3000
x
Check the "main menu" to see if the pre-set values of the factory settings are sufficient
for the upper opereating pressure (
SP2
) and the lower operating pressure (
RP2
).
The following applies:
RP2 < SP2
.
x
In the "main menu", please set the value for the upper operating pressure (
SP2
)
applying in your system.
x
In the "main menu", please set the value for the lower operating pressure (
RP2
)
applying in your system.
x
Set
P.Low
in the menu "expanded functions".
x
Operate the system under the normal operating conditions.
x
Apply the upper and lower operating pressure twice in order to check the switching
behaviour of switching output 2 (accumulator charge function) for proper functioning.
x
Set and hold the upper operating pressure applying for the system.
x
Lower the system pressure down to
p
P.Low.
NOTE:
The monitoring of the pressure signal according to p0 is only performed within a
range between RP2 and P.Low. The pressure must be
P.Low when the hydro
accumulator is completely emptied in order to enable the software of the
EDS 3400 to complete the monitoring and to show p0 in the display.
x
Check if p
0
is displayed in the "main menu".
x
Save the value for p
0
in the menu "expanded functions" by means of
TEAC
.
x
Check the saved value for p
0
in the menu "expanded functions" by means of
TVal
.
