4 Technical Description of the CS
4.1 General data
The ContaminationSensors of the CS 2000 series are stationary measuring devices
for continuously monitoring solid particle contamination in hydraulic systems.
They have been specifically developed for applications in the test rig area, where it
is necessary to record measurement values in the hydraulic system and display
these values remotely on the control panel, as well as to store the data on a PC.
Device types CS 2030, 2130 and 2230 are designed for applications with mineral
oils and various synthetic hydraulic fluids (e.g. HLP, HLPD), whilst types CS 2031,
2131 and 2231 are only allowed to be operated with certain fluids in the HFD group
(e.g. HFD-R, phosphate tester). If you are unclear about suitability for use with
particular fluids, please contact the sensor manufacturer to inquire about usability.
Because the other device properties are identical, the types CS 203X, 213X and
223X are dealt with below for the sake of simplicity.
Particulate contamination is recorded using a fiber-optic infrared measurement cell
patented by HYDAC and can be output as particle counts or as contamination
classes in accordance with NAS 1638 or ISO 4406:1987 / SAE AS 4059 or ISO
4406:1999.
The particulate contamination is recorded in the following particle size ranges:
CS 203x
Particle count / NAS channels 5..15µm 15..25µm 25..50µm > 50µm
ISO channels > 5µm > 15µm
CS 213x
Particle count / NAS channels 2..5µm 5..15µm 15..25µm > 25µm
ISO channels > 2µm > 5µm > 15µm
CS 223x
Particle count / NAS channels 4..6µm
(c)
6..14µm
(c)
14..21µm
(c)
> 21µm
(c)
ISO channels > 4µm
(c)
> 6µm
(c)
14 µm
(c)
The CS is designed to be connected to low-pressure hydraulic lines from which a
small oil flow portion is branched off for measurement.
By varying the internal orifices, it is possible for the sensors to be configured at the
factory for various operating conditions (pressure/viscosity ranges).
An integrated pressure relief valve protects the ContaminationSensor against
pressures of as much as 350 bar / 5000 psi.
The measured contamination class or the particle counts are continuously output via
various (some optional) electrical outputs (relay, PLC interface, serial display
interface, analog current output 4-20 mA, fieldbus interface) and can thus be
registered and displayed by means of a PLC, an analog voltmeter or a PC.

5.2 Electrical connection of the CS
Before continuing, check whether the CS is suitable for your display/data capturing
system by carefully examining the technical specifications.
First connect the signal lines (pins/terminals 1 to 23).
Then connect the supply voltage.
CS starts measurement operation as soon as the supply voltage is applied.
5.3 Selecting a measurement point
1
The measurement point should be selected so that the measured volume
comes from a turbulent area with a good through-flow. For example: on a
pipe elbow, etc.
2
The CS has to be installed in the vicinity of the measurement point in order
to obtain precision-timed results.
3
While installing the measurement line, avoid creating a "siphon" trap for
sedimentation (particle deposits in the line).

5.4 Hydraulic connection of the CS
Determine the system pressure of the hydraulic facility and see whether it is within
the permissible range for the INLET port.
TIP
The pressure in the measurement cell is not allowed to exceed 40 bar!
The built-in pressure relief valve does not open until there is a pressure differential
of 40 bar between the INLET and OUTLET.
If pressure values greater than 40 bar occur on the INLET connection and the
OUTLET connection is not depressurized at the same time, the CS must be
protected by an additional pressure relief valve (e.g.: ConditioningModule Inlet, CMI).

Example for protecting the CS if OUTLET is not depressurized
Warning: Oil starts to flow through the CS as soon as the
system has been connected to the pressure fitting.
This is why it is vital that connection be done in the
sequence specified above.
The return-line connector (OUTLET) must never be
obstructed or closed off!
1. Connect the CS hydraulically to your system as follows:
2. First connect the return-flow line (not supplied) to the OUTLET port of the
CS.
(Connector thread: G1/4, ISO 228. Recommended internal diameter of
conduit: >4 mm)
3. Now connect the other end of the return-flow line, e.g. to the system tank.
4. Check the pressure at the measurement point; it has to be within the
specified limits.

5. First connect the measurement line (not supplied) to the INLET port of the
CS.
(Connector thread: G1/4, ISO 228. Recommended internal diameter of
conduit (to prevent particle sedimentation): ≤ 4 mm)
6. Now connect the other end of the measurement line to the measurement
point.
7. Installation of the CS is now complete and it now continuously outputs the
measured values via the electrical interface(s).
5.5 Removing the CS from the Hydraulic System
1. Disconnect the CS from the voltage supply.
2. Disconnect the other electrical connectors.
3. Remove the measurement hose from the hydraulic system first, then from
the INLET port of the CS.
4. Remove the return-flow line from the OUTLET port of the CS .
The CS can now be removed.

6 Description of the Measuring Modes
6.1 Mode M1: Measure
Continuous measurement without special switching functions.
The current measurement result is output via the available interfaces after the
measurement interval has elapsed.
6.2 Mode M2: Measure and switch
Continuous measurement, with relays 1 and 2 being switched according to the set
measuring channels, switching functions and limit values.
The current measurement result is output via the available interfaces after the
measurement interval has elapsed.
6.3 Mode M3: Filter until
Measuring mode in which relay 1 is closed, until 5 successive measurements reach
or are cleaner than the set target cleanliness value. Measurement in mode 3 is then
stopped.
Once relay 1 has been opened, it remains open until a measurement is restarted. (A
restart can be triggered using the DIN measurement bus interface, the RS 232
display interface or by switching the electrical power supply off/on.)
6.4 Mode M4: Filter from until
Measuring mode in which relay 1 is closed, until 5 successive measurements reach
or are cleaner than the set target cleanliness value (lower limit).
The relay is then opened and the test cycle time is started. After the test cycle time
has elapsed, relay 1 is closed and a measurement is performed.
If the upper cleanliness value (upper limit) is reached or not exceeded, relay 1
remains closed until 5 successive measurements once again reach or are cleaner
than the set target cleanliness value.
If the upper cleanliness value (upper limit) is not reached or was exceeded, relay 1
is opened again and the test cycle time is restarted.
6.5 Switching behavior of the relays:
The following table describes the switching behavior of the three relays in the
various measuring modes.
The position of the relays is updated after a measurement interval has elapsed, by
comparing the current measured values with the limit values.
Directly after the CS is switched on, the Common (C) and Normally Closed (NC)
contacts of all relays are connected together. As soon as the operational readiness
of the CS has been established, the C and NO contacts are connected together on
the Ready relay.

Relays 1 and 2 are not switched until after the first measurement interval has
expired.
