1 Safety instructions

1.1 Designated use

Liquiline CM442 is a two-channel transmitter for connecting digital sensors with Memosens

technology in non-hazardous locations.

The device is designed for use in the following applications:

• Water and wastewater

• Power stations

• Chemical industry

• Industrial wastewater treatment plants

If the device is used for any purpose other than that described, this poses a threat to the safety

of people and the entire measuring system and is thus not permitted.

The manufacturer does not accept liability for damage caused by improper or non-designated

use.

1.2 Incoming acceptance, transport, storage

• Check the scope of delivery against the delivery papers and your order to ensure it is complete

and nothing is missing.

• Pack the product in such a way as to protect it reliably against impact and moisture for storage

and transportation. Optimum protection is provided by the original packaging materials. In

addition, the permitted ambient conditions must be observed (see Technical data).

• If you have any queries, please contact your supplier or local sales center.

1.3 Installation, commissioning and operation

Observe the following points:

• Installation, commissioning, operation and maintenance of the measuring system must only

be carried out by trained technical personnel.

The technical personnel must be authorized to perform the tasks by the owner-operator.

• The electrical connection may only be established by an electrical technician.

• The technical personnel must have read and understood these Operating Instructions and

must follow the instructions they contain.

• 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.

3.3 Identification of inputs and outputs

The electronic configuration follows a modular concept:

• Several slots are available for electronics modules.

• These slots are numbered consecutively in the housing. Slot 1 is always reserved for the basic

module.

• Each electronics module has one or more inputs or outputs.

• The inputs and outputs are also numbered consecutively per electronics module.

• The software automatically detects what inputs and outputs are available.

Measured value display:

1. Channel number (English), e.g. "CH1:" for channel 1

2. Slot and input number, e.g. "1:1" for slot 1 (basic module) and the related input 1

3. Connected sensor type, e.g. "ORP"

4. Current measured value, e.g. 301 mV

The same logic is applied to number the outputs: name of the output, slot number and

output number, e.g. "current output 1:1".
