Make sure that the protection provided by this equipment is not impaired. Do not use or install this equipment in any manner other than that specified in this manual.
2.1.1 Use of hazard information
DANGER
Indicates a potentially or imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
Indicates a potentially or imminently hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that may result in minor or moderate injury.
NOTICE
Indicates a situation which, if not avoided, may cause damage to the instrument. Information that requires special emphasis.
2.1.2 Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or damage to the instrument could occur if not observed. A symbol on the instrument is referenced in the manual with a precautionary statement.
2.1.2 Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or damage to the instrument could occur if not observed. A symbol on the instrument is referenced in the manual with a precautionary statement.

| This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.
---|---
| This symbol indicates that a risk of electrical shock and/or electrocution exists.
| This symbol indicates the presence of devices sensitive to Electro-static Discharge (ESD) and indicates that care must be taken to prevent damage with the equipment.
****| Electrical equipment marked with this symbol may not be disposed of in European domestic or public disposal systems. Return old or end-of-life equipment to the manufacturer for disposal at no charge to the user.

2.3 Product overview
The conductivity module lets a digital SC Controller connect to an analog sensor. The module connects to one of the analog module slots (slot 3 or 4) in the controller.
For calibration and operation of the sensor, refer to the sensor user manual and the SC Controller documentation.
2.4 Product components
Make sure that all components have been received. Refer to Figure 1. If any items are missing or damaged, contact the manufacturer or a sales representative immediately.

A list of Modbus registers is available for network communication. Refer to the manufacturer’s website for more information.

Section 3 Installation

DANGER
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the document.
DANGER
Electrocution hazard. Remove power from the instrument before this procedure is started.
DANGER
Electrocution hazard. High voltage wiring for the controller is conducted behind the high voltage barrier in the controller enclosure. The barrier must remain in place unless a qualified installation technician is installing wiring for power, alarms, or relays.
WARNING
Electrical shock hazard. Externally connected equipment must have an applicable country safety standard assessment.
NOTICE
Make sure that the equipment is connected to the instrument in accordance with local, regional and national requirements.
NOTICE
Potential Instrument Damage. Delicate internal electronic components can be damaged by static electricity, resulting in degraded performance or eventual failure.
Refer to the steps in this procedure to prevent ESD damage to the instrument:

• Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit or pipe to discharge static electricity from the body.
• Avoid excessive movement. Transport static-sensitive components in anti-static containers or packages.
• Wear a wrist strap connected by a wire to earth ground.
• Work in a static-safe area with anti-static floor pads and work bench pads.

3.2 Install the module
To install the module and connect the sensor, refer to the illustrated steps that follow and the applicable wiring table (Table 4 or Table 5).
Notes:

• Make sure that the controller is compatible with the conductivity module. Contact technical support.

• Make sure that the routing of the sensor cable prevents exposure to high electromagnetic fields (e.g., transmitters, motors and switching equipment). Exposure to these fields can cause inaccurate results.

• To keep the enclosure rating, make sure that all unused electrical access holes are sealed with an access hole cover.

• To maintain the enclosure rating of the instrument, unused cable glands must be plugged.

• Connect the module to one of the two slots on the right side of controller (slots 3 and 4). Refer to Figure 2. The controller has two analog module slots. The analog module slots are internally connected to the sensor channel. Make sure that the analog module and the digital sensor are not connected to the same channel.
  Note: Make sure that only two sensors are installed in the controller. Although two analog module ports are available, if a digital sensor and two modules are installed, only two of the three devices will be seen by the controller.

• Turn the rotatory switch of the module to configure the module based on the applicable sensor. Refer to Table 3.
