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.

Socket Pin Description
A0046897
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.
