4.5 Grounding the Measuring Sensor
• The measuring sensor must be properly grounded.
• The grounding cable should not transmit any
interference voltages.
• Do not use the grounding cable to connect more than
one device to ground.
• The measuring sensors are connected to ground by
means of a functional grounding conductor FE.
• In hazardous areas, grounding is used at the same
time for equipotential bonding. Additional grounding
instructions are provided in the separate “Ex
documentation”, which are only supplied together
with hazardous area equipment.
4.6 Connecting Power, All Housing Variants
• The protection category depends on the housing
versions (IP65 to 67 to IEC 529 / EN 60529 or
NEMA4/4X/6).
• The housings of the devices, which are designed
to protect the electronic equipment from dust and
moisture, should be kept well closed at all times.
Creepage distances and clearances are dimensioned
to VDE 0110 and IEC 664 for pollution severity 2.
Supply circuits are designed for overvoltage category
III and the output circuits for overvoltage category II.
• Fuse protection (IN ≤ 16 A) for the infeed power
circuit, as well as a separator (switch, circuit breaker)
to isolate the signal converter must be provided close
to the device. The separator must be marked as the
separator for this device.
DANGER
There should be no difference in
potential between the measuring
sensor and the housing or
protective earth of the signal
converter!
DANGER
The device must be grounded in
accordance with regulations in
order to protect personnel against
electric shocks.
DANGER
For devices used in hazardous
areas, additional safety notes
apply; please refer to the Ex
documentation.

4.8 Description of the Inputs and Outputs
4.8.1 Current Output
• All outputs are electrically isolated from each other
and from all other circuits.
• All operating data and functions can be adjusted.
• Passive mode: external power Uext ≤ 32 VDC at I ≤
22 mA
• Active mode: load impedance RL ≤ 1 kΩ at I ≤ 22
mA; RL ≤ 450 Ω at I ≤ 22 mA for Ex i outputs
• Self-monitoring: interruption or load impedance too
high in the current output loop
• Error message possible via status output, error
indication on LCI40 display.
• Current value error detection can be adjusted. Default
setting: 3.6 mA
• Automatic range conversion via threshold or
control input. The setting range for the threshold is
between 5 and 80% of Q
(corresponding ratio from smaller to larger range of
1:20 to 1:1.25). Signaling of the active range possible
via a status output (adjustable).
• Forward / reverse flow measurement (F/R mode) is
possible.

4.8.2 Pulse and Frequency Output
• All outputs are electrically isolated from each other
and from all other circuits.
• All operating data and functions can be adjusted.
• Passive mode:
External power supply required: U
I ≤ 20 mA at f ≤ 10 kHz (over range up to f
kHz)
I ≤ 100 mA at f ≤ 100 Hz
• Active mode:
Use of the internal power supply: U
I ≤ 20 mA at f ≤ 10 kHz (over range up to f
kHz)
I ≤ 20 mA at f ≤ 100 Hz
• Scaling:
Frequency output: in pulses per time unit (e.g. 1000
pulses/s at Q
Pulse output: quantity per pulse.
• Pulse width:
Symmetric (pulse duty factor 1:1, independent of
output frequency)
Automatic (with fixed pulse width, duty factor approx.
1:1 at Q
Fixed (pulse width adjustable as required from 0.05
ms to 2 s)

Assembly materials and tools are
not part of the delivery. Use the
assembly materials and tools In
compliance with the applicable
occupational health and safety
directives.

Housing
1. Open the housing cover.
2. Push the prepared cable through the cable entry and
connect the necessary conductors.
3. Connect the shield if necessary.
4. Close the touch guard.
5. Close the housing cover.
4.9.2 Laying Electrical Cables Correctly
Protect Housing from Dust and Water
1. Lay the cable in a loop just before the housing.
2. Tighten the screw connection of the cable entry securely.
3. Never mount the housing with the cable entries facing
upwards.
4. Seal cable entries that are not needed with a plug.
DANGER
All work on the electrical
connections may only be carried
out with the power disconnected.
Take note of the voltage data on
the nameplate!
Information
For frequencies above 100 Hz,
shielded cables are to be used
in order to reduce effects from
electrical interferences (EMC).
Information
Each time a housing cover is
opened, the thread should be
cleaned and greased. Use only
resin-free and acid-free grease.
Ensure that the housing gasket
is properly fitted, clean and
undamaged.
