1.4 Operational safety

►Prior to commissioning the entire measuring point, check that all connections are correct. Make

sure that electric cables and hose connections are not damaged.

►Do not commission damaged products. Protect them against unintentional startup. Label and

identify the damaged product as defective.

►If the faults cannot be eliminated, take the products out of service and protect them against

unintentional startup.

CAUTION

!

The cleaning system is not switched off during calibration or maintenance activities

Risk of injury due to medium or cleaning agent

►If a cleaning system is connected, switch it off before removing a sensor from the medium.

►If you are not switching off the cleaning system because you wish to test the cleaning function, wear

protective clothing, goggles and gloves or take other appropriate measures.

1.5 Product safety

3.3 Device architecture

3.3.1 Slot and port coding

The electronic configuration follows a modular concept:

• Several slots are available for electronics modules.

• These slots are numbered consecutively in the housing. Slots 0 and 1 are always reserved for the basic

module.

• Each electronics module has one or more inputs or outputs or relays, referred collectively to as

"ports".

• Ports are numbered consecutively for each electronics module and are automatically recognized by

the software.

a0015819-en

Fig. 3: Slot and port coding of hardware and on-screen display

Liquiline CM442/CM444/CM448 Device description

Endress+Hauser 11

• The outputs and relays are named after their function, e.g. "Current output", and are displayed in

ascending order with the slot and port numbers

Example, →å3:

– If "Current output 2:1" is displayed, this means:

Slot 2 (e.g. AOR module) : Port 1 (current output 1 of AOR module)

• Inputs are assigned to measuring channels in ascending order "Slot:Port number"

Example:

– If "CH1: 1:1 pH glass" is displayed, this means:

Channel 1 (CH1) is slot 1 (basic module) : port 1 (input 1) and a pH glass sensor is connected here

Consequently, this results in the following unique terminal name:

Slot No. : Port No. : Terminal

3.3.2 Terminal diagram

Example for creating a terminal diagram:

Device with 4 inputs for digital sensors, 4 current outputs and 4 relays

• Basic module BASE-E (contains 2 sensor inputs, 2 current outputs)

• Module 2DS (2 sensor inputs)

• Module 2AO (2 current outputs)

• Module 4R (4 relays)
