6.6 Self-Test for Broken Conductors
and Short-Circuiting
While controlling the valves and
sensors, the Sartocheck
hardware can check whether there
are any broken conductors or
short-circuits.

Calibration

The calibration function is used to
calibrate the internal pressure sen-
sor with the aid of more precise ref-
erence measuring devices and to
adjust it if necessary. Each sensor
runs its own calibration date.
An adjustment routine automatical-
ly follows the test. The test can
also be activated separately.
Sartocheck ® 3 plus saves the raw
data for the calibration record in
permanent memory.
The operator can use the following
sensor types for determining the
reference pressure:
– Absolute pressure sensor:
The reference pressures are meas-
ured directly.
– Relative pressure sensor:
The measured reference pressures
relate to the ambient pressure. The
ambient pressure must be known or
measured with additional reference
measuring equipment.

Internal Pressure Sensor

Sartocheck ® 3 plus sets either 6 or 8
pressure values and compares them
with the internal pressure sensor
and the pressure values measured
on the reference measuring instru-
ment (connected to the "OUT"
connector) to calculate scale and
linearization.

Pressure Gauge Function

In the pressure gauge function, the
Sartocheck
® 3 plus digital pressure measuring device.
To do so, it uses the internal
pressure sensor.

Cleaning|Drying

Through the pneumatic connectors,
Sartocheck
almost all internal volumes. The
user is responsible for ensuring that
no damage occurs to any compo-
nents of the Sartocheck
to the pressure built up by the
pump used in the cleaning.

Safety Functions

– As one of its technical options,
Sartocheck
step Initialization|Security Status in
the event of a power failure. Basi-
cally, what this step does is close
the compressed air supply and the
block valve to the filter housing.
– Sartocheck
ble for ensuring whether the maxi-
mum pressure for the compressed
air supply to the filter housing is
too high. That means the user must
make sure that the initial pressure
cannot damage the filter housing.

Software Update

The operating software on
Sartocheck
a corresponding program run
exclusively with an external Laptop
(via the jacks Service MU| Service
TU). Since the configuration data
are localized in a battery-backed
RAM, they remain unchanged
during any software update.

Serial Number

Every unit bears its own unique
serial number. The serial number
may not be changed during a
software update.
– The serial number is entered for
the first time during production
of the unit.
– If the PCB has to be replaced
during repairs that may arise later,
the unit must be assigned the
exact same serial number that is
imprinted on the manufacturer's
label.
