5.2.2 Synchronization and multiplex operation
Overview
Synchronization and multiplex operation are not available in IO-Link mode.
Synchronization and multiplex operation
In synchronization or multiplex operation, a maximum of 20devices can be intercon‐
nected via pin5 (MF). Synchronization and multiplex operation prevent mutual inter‐
ference of several interconnected devices. The detection area increases to the area
covered by all interconnected devices.
Synchronization operation
In synchronization operation, all devices send and receive the ultrasonic pulses simulta‐
neously. The device detects objects, but does not record the position of the objects.
Synchronization operation starts automatically as soon as the devices are intercon‐
nected via PIN 5 (MF).
The response time of the overall system is determined by the sensor with the highest
response time.
Multiplex operation
In multiplex operation, all devices transmit and receive the ultrasonic pulses one after
the other in a defined sequence. The device detects objects and also determines the
position of the objects. To switch to multiplex operation, assign different addresses to
the connected devices via SOPAS ET, IO-Link or the Connect+ software.
Since measurement by the sensors is done in alternation, the response time of the
total system is increased in accordance with the formula:
Total response time = 4 × [(1.1ms × n) + 0.75ms × (1 + 2 + … + n)] + sum of the
response times of all connected devices

6 Electrical installation
6.1 Wiring instructions
NOTE
Pre-assembled cables can be found on the product page.
The page can be accessed via the SICK Product ID: pid.sick.com/{P/N}/{S/N}
{P/N} corresponds to the part number of the product, see type label.
{S/N} corresponds to the serial number of the product, see type label (if indicated).
NOTICE
Faults during operation and defects in the device or the system
Incorrect wiring may result in operational faults and defects.
■Follow the wiring notes precisely.
The enclosure rating stated in the technical data is achieved only with a screwed plug
connector or protective cap.
Connect the connecting cables in a de-energized state. Do not switch on the supply
voltage until installation is complete and all connecting cables are connected to the
device and control.
The supply voltage must be as specified in the technical data, see "Technical data",
page 30.
When commissioning, protect the device from moisture and contamination.
6.2 Prerequisites for safe operation of the device
WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other grounded
devices in the system, faulty grounding of the device can give rise to the following
dangers and faults:
•Dangerous voltages are applied to the metal housings.
•Devices will behave incorrectly or be destroyed.
•Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
•Only skilled electricians should be permitted to carry out work on the electrical
system.
•If the cable insulation is damaged, disconnect the voltage supply immediately and
have the damage repaired.
•Ensure that the ground potential is the same at all grounding points.
•Where local conditions do not meet the requirements for a safe earthing method,
take appropriate measures. For example, ensure low-impedance and current-carry‐
ing equipotential bonding.
The device is connected to the peripheral devices (any local trigger sensor(s), system
controller) via shielded cables. The cable shield – for the data cable, for example –
rests against the metal housing of the device.
The device can be grounded through the cable shield or through a blind tapped hole in
the housing, for example.

If the peripheral devices have metal housings and the cable shields are also in contact
with their housings, it is assumed that all devices involved in the installation have the
same ground potential.
This is achieved by complying with the following conditions:
■Mounting the devices on conductive metal surfaces
■Correctly grounding the devices and metal surfaces in the system
■If necessary: low-impedance and current-carrying equipotential bonding between
areas with different ground potentials

9Shielded electrical cable
If these conditions are not fulfilled, equipotential bonding currents can flow along the
cable shielding between the devices due to differing ground potentials and cause the
hazards specified. This is, for example, possible in cases where there are devices within
a widely distributed system covering several buildings.
Remedial measures
The most common solution to prevent equipotential bonding currents on cable shields
is to ensure low-impedance and current-carrying equipotential bonding. If this equipo‐
tential bonding is not possible, the following solution approaches serve as a suggestion.
NOTICE
We expressly advise against opening up the cable shields. This would mean that the
EMC limit values can no longer be complied with and that the safe operation of the
device data interfaces can no longer be guaranteed.
Measures for widely distributed system installations
On widely distributed system installations with correspondingly large potential differen‐
ces, the setting up of local islands and connecting them using commercially available
electro-optical signal isolators is recommended. This measure achieves a high degree
of resistance to electromagnetic interference.

9Optical fiber
The use of electro-optical signal isolators between the islands isolates the ground loop.
Within the islands, a stable equipotential bonding prevents equalizing currents on the
cable shields.
Measures for small system installations
For smaller installations with only slight potential differences, insulated mounting of the
device and peripheral devices may be an adequate solution.
Even in the event of large differences in the ground potential, ground loops are effec‐
tively prevented. As a result, equalizing currents can no longer flow via the cable shields
and metal housing.
NOTICE
The voltage supply for the device and the connected peripheral devices must also
guarantee the required level of insulation.
Under certain circumstances, a tangible potential can develop between the insulated
metal housings and the local ground potential.

Digital output: Digital output is active
Analog output: Object is in scaling range

Teach-in
•No object detected
•Object outside the detection range
•First switching point is within and second switching
point is outside the detection range1)
•Scaling < 1mm is taught-in2)
The existing switching points are retained.
O = Lights up; Ö = Flashes; o = Does not light up.
1) Applies to the switching window and background switching functions.
2) Applies when teaching in the analog output.
7.2 Digital output1 teach-in

•N/O contact
•UM18-2xxxxExxx: Switching point at half (Q1) and maximum (Q2) operating range
7.2.2 Teaching in switching point (Single Point Mode)
Overview
When the object is located below the taught-in switching point, the digital output is
active.
Approach
Teaching in the switching point (distance to object as switching point)
