protection clamp 1-1. The fused supply voltage for the metal particle counter is connected on
the overvoltage protection clamps 2-2 and GND.
A MetallicContamination sensor of the series MCS 1000 of the company HYDAC can be
connected in a similar way. If the user omits the self-test functionality it is possible to count the
ferromagnetic particles on channel C-01 and the non-ferromagnetic particles on channel C-02.
2.3.13 Internal connection of power supply terminals of type EL9410 and EL9505
The power supply terminals of the Peakanalyzer are labeled in the range of X6 to X9.
If the system current Is of the IPC connection has reached a capacity of 2 A, additional supply
terminals of type EL9410 are used to increase the system current. The power supply voltage
Us is connected to the clamps labeled with 24V and 0V at the power supply terminals labeled
with X6, X7 or X8. The power supply voltage is always 24 V
DC
. It supplies the EtherCAT bus
system of the Peakanalyzer with the operating voltage. The EtherCAT bus connects the
individual terminals with the system and ensures the data exchange.
The power supply terminal of type EL9410 suffers as supply and refresh of the EtherCAT bus.
One E-Bus supply branch can only be equipped with terminals that do not exceed 2 A
maximum current in sum. If the sum of 2 A is exceeded a power supply terminal of type EL9410
is used to increase the maximum current by 2 A. The clamps labeled with 24V and 0V can only
drive a current of 2 A. If one or more terminals of type EL9410 are used the input power supply
has to deliver more than 2 A. Thus each indi24V branch of the E-Bus supply must be
protected by a 2 A T fine wire fuse. The fused wires must have a cross section to drive at least
3 A.
Furthermore the power supply terminal of type EL9410 is connected to the voltage Up for the
supply of external sensors on the I/O-terminals. This is done via the clamps labeled with a
black + on red ground and black - on blue ground. The voltage Up is limited to +24 V
DC
and is
connected to the power contacts of the I/O-terminals. A maximum current of 10 A is allowed
for these power contacts. If the power supply source can drive more than 10 A, the wires must
be protected with a 10 A fuse. If the power supply source supplies less than 10 A, the fuse can
be omitted. In all cases the cross section of the wire must be at least 1.5 mm². In a normal
case the power supply source has a capacity of 2.5 A or 3 A. This than serves as fuse for the
power contacts.
Dependent on the use case and the amount of equipped terminals that follows the power
supply terminal of type EL9410 one or two power supply sources can be used to connect the
system supply Us and the supply for external sensors Up. The variants for internal connection
of the power supply terminal EL9410 are shown in Picture 4 and Picture 7.
The power supply terminal of type EL9505 with the label X9 converts the input voltage of 24
V
DC
to an output voltage of 5 V
DC
for external consumers. The input voltage Us is connected
to the clamps labeled with 24V and 0V. The output voltage is available via the clamps labeled
with 5V and 0V. Furthermore the following terminals are supplied with 5 V
DC
via the power
contacts. The terminal is short circuit proofed and can provide a maximum current of 500 mA.
There is no galvanic isolation between the input voltage and the output voltage. Two green
Power-LEDs are showing the operating state of the input and output voltage. A red LED shows
an overvoltage or short circuit case. The internal connection of the power supply terminal of
type EL9505 is shown in Picture 10.
