1) Example: you want to loop the signal from the alarm relay to a siren and a lamp. The terminals on the
alarm relay only accommodate one cable. Route the signal from the alarm relay to a terminal on the distributor block. The block's terminals are all interconnected. You therefore have 3 additional terminals on this block from where you can carry the signal forward to the consumer (siren, lamp etc.). The signal can be multiplied in this way.

5.3.1 DIN rail mounting

The mounting procedure is the same for all Liquiline devices. The example shows a CM448R.
1. In the order configuration, the securing clips are "tightened" to secure the DIN rail. Release the securing clips by pulling them downwards. 
2. Attach the device from the top to the DIN rail (a) and secure it by pressing down (b). 
3. Slide the securing clips upwards until they click, thereby securing the device to the DIN rail.
4. Mount the external power unit in the same way.

5.3.2 Wall mounting

Mounting material (screws, dowels) are not included in the scope of delivery and must be provided by the customer.
The external power unit can be mounted on a DIN rail only.
Use the back of the housing to mark the mounting holes.
1. Drill the corresponding holes and insert wall plugs if necessary.
2. Screw the housing onto the wall.

: Sensor/device condition or maintenance timer > 5 ≤ 20 %, maintenance not yet
urgent but should be scheduled
: Sensor/device condition or maintenance timer < 5 %, maintenance is

• The Heartbeat sensor condition is the assessment of the calibration results and the sensor diagnostic functions.
An unhappy smiley can be due to the calibration result, the measured value status or to the operating hours limit having been exceeded. These limits can be configured in the sensor setup in a way that adapts the Heartbeat diagnostics to the application.
Heartbeat and NAMUR category
The Heartbeat status indicates the sensor or device condition while the NAMUR categories (F, C, M, S) assess the reliability of the measured value. The two conditions can correlate but do not have to.
Example 1
• The number of remaining cleaning cycles for the sensor reaches 20% of the defined
maximum number. The Heartbeat symbol changes from to . The measured value is still reliable so the NAMUR status signal does not change.
• If the maximum number of cleaning cycles is exceeded, the Heartbeat symbol changes
from to . While the measured value can still be reliable, the NAMUR status signal changes to M (maintenance required).
Example 2 The sensor breaks. The Heartbeat status changes immediately from to and the NAMUR status signal also changes immediately to F (failure).

The Dynamic Host Configuration Protocol (DHCP) makes it possible to assign the network configuration to clients via a server. With DHCP, it is possible to automatically integrate the device into an existing network without the need for manual configuration. Normally only the automatic assignment of the IP address must be configured at the client. During startup, the IP address, the netmask and the gateway are retrieved from a DHCP server.

netmask specifies which IP addresses this device searches for in its own network and which addresses it could access in other networks via a router. It therefore divides the IP address into a network part (network prefix) and a device part.

The change in the process - for example, concentration measurement with a varying medium composition (milk, cream, yogurt) - can be communicated to the transmitter by a binary input signal. Binary inputs and fieldbus signals are available. For this, your device must have the appropriate hardware and the necessary activation codes.
You can specify a maximum of 3 dataset switches. Each switch has two states (binary encoding). Therefore you have a maximum of 23=8 signal combinations for dataset switching.
1. Open the menu: Setup/Inputs/Photometer/Extended setup/Ext. dataset control.
2. Dataset switch 00x, Dataset switch 0x0, Dataset switch x00: First set up the dataset switches (maximum 3 switches). You can use a binary input or one of a maximum of 8 fieldbus signals as the signal source.

is connected. Unipolar- Assign to the output to which an actuator that can decrease the measured value is connected. To output the manipulated variable of a two-sided controller, positive manipulated variables and negative manipulated variables generally have to be output to different actuators, as most actuators are able to influence the process in one direction only (not in both). For this purpose, the instrument splits the bipolar manipulated variable y into two unipolar manipulated variables, y+ and y. Only the two unipolar manipulated variable parts are available for selection for outputting to modulated relays. If outputting the values via a current output, you also have the possibility of outputting the bipolar manipulated variable y to one current output only (split range).

10.4.2 Alarm relay and optional relays

The basic version of the device always has one alarm relay. Additional relays are also available depending on the version of the device.
The following functions can be output via a relay:
• Limit switch status
• Controller manipulated variable for controlling an actuator
• Diagnostic messages
• Status of a cleaning function in order to control a pump or a valve
You can assign a relay to multiple inputs in order to clean several sensors with just one cleaning unit, for example.

Outputting diagnostic messages via the relay
If a relay is defined as a diagnostic relay (Function = Diagnostics), it works in the "fail­safe mode".
This means that the relay is always energized ("normally closed", n.c.) in the basic state if an error is not present. In this way it can also indicate a drop in voltage, for example. The alarm relay always works in the failsafe mode.
You can output two categories of diagnostic messages via the relay:
• Diagnostic messages from one of the 4 Namur classes →  137
• Diagnostic messages which you have individually assigned to the relay output
A message is individually assigned to the relay output at 2 specific points in the menu:

2. The cleaning trigger is transferred to another device via a binary output. This does not have its own connected cleaning unit, but its sensors are installed in the medium affected by cleaning the master and are set to hold by the trigger.
3. The trigger is transferred via an additional binary output to another device, whose connected sensors have their own cleaning units. The signal can be used to simultaneously activate a self-cleaning with the master.

Switches the input on/off
Static signal Use this setting to read out the position of, for example, an on/off switch, an inductive proximity switch or a PLC binary output. Signal application: for measuring range switching, acceptance of an external hold, as a cleaning trigger or for controller activation
PFM The PFM setting produces a pulse-frequency­modulated signal that is subsequently available on the device as a quasi-continuous process value. Example: Measuring signal of a flowmeter
Specifies which input signal levels should activate, for example, measuring range switching or a cleaning.
Low Input signals between 0 and 5 V DC
High Input signals between 11 and 30 V DC
Maximum frequency of the PFM input signal Is to equal the maximum possible upper limit of the measuring range. If the value selected is too small, higher frequencies will not be detected. If the value is too large, on the other hand, the resolution for small frequencies will be relatively inexact.
Select the signal type.
Specify the number of decimal places.
