TOC Analyzer CA78 Basic safety instructions

Endress+Hauser 5

2 Basic safety instructions

2.1 Requirements for the personnel

• Installation, commissioning, operation and maintenance of the measuring system may

be carried out only by specially trained technical personnel.

• The technical personnel must be authorized by the plant operator to carry out the

specified activities.

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

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

and must follow the instructions contained therein.

• Faults at the measuring point may only be rectified by authorized and specially trained

personnel.

Repairs not described in the Operating Instructions provided must be carried out only

directly at the manufacturer's site or by the service organization.

2.2 Intended use

The analyzer is designed to determine the total organic carbon in ultrapure water

applications that meet the following conditions:

• Conductivity < 10 µS/cm

• pH range: neutral

Use of the device for any purpose other than that described, poses a threat to the safety of

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

The manufacturer is not liable for damage caused by improper or non-designated use.

2.3 Workplace safety

As the user, you are responsible for complying with the following safety conditions:

• Installation guidelines

• Local standards and regulations

Electromagnetic compatibility

• The product has been tested for electromagnetic compatibility in accordance with the

applicable international standards for industrial applications.

• The electromagnetic compatibility indicated applies only to a product that has been

connected in accordance with these Operating Instructions.

2.4 Operational safety

Before commissioning the entire measuring point:

1. Verify that all connections are correct.

2. Ensure that electrical cables and hose connections are undamaged.

3. Do not operate damaged products, and protect them against unintentional operation.

4. Label damaged products as defective.

During operation:

‣If faults cannot be rectified:

products must be taken out of service and protected against unintentional operation.

1: 4 (0) - 20 mA (GND)

2: 4 (0) - 20 mA (+)

TOC (0 to set limit)

3: 4 (0) - 20 mA (GND)

4: 4 (0) - 20 mA (GND)

Δ conductivity (0 to set limit)

5: Relay

6: Relay

Group error message or limit value overshoot depending on the

selected option

Pin 1/2: Provides an analog signal between 4 and 20 mA for the TOC measured value

between 0 and the limit (to be configured in the Settings menu, Options 1 tab).

Pin 3/4: Provides an analog signal between 4 and 20 mA for the Δ conductivity value

between 0 and the limit in μS/cm (to be configured in the Settings menu, Service 1 tab).

Pin 5/6: Acts as an NO contact if the configured TOC or conductivity limit value is

exceeded in the "analog output" option, or as an NC contact in the option with a group error

message in the event of a power failure, a reaction of the leak, lamp or pressure sensor

and if one of the two conductivity sensors is over range.

The measured value is updated every minute. During a calibration, the last value is

displayed until a new measurement is started.
