Certification

Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:

Supporting test records reside with the manufacturer.

This Class A digital apparatus meets all requirements of the Canadian Interference-Causing

Equipment Regulations.

Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne

sur les équipements provoquant des interférences.

FCC Part 15, Class "A" Limits

Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC

Rules. Operation is subject to the following conditions:

1. The equipment may not cause harmful interference.

2. The equipment must accept any interference received, including interference that may cause

undesired operation.

Changes or modifications to this equipment not expressly approved by the party responsible for

compliance could void the user's authority to operate the equipment. This equipment has been tested

and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.

These limits are designed to provide reasonable protection against harmful interference when the

English 5

equipment is operated in a commercial environment. This equipment generates, uses and can

radiate radio frequency energy and, if not installed and used in accordance with the instruction

manual, may cause harmful interference to radio communications. Operation of this equipment in a

residential area is likely to cause harmful interference, in which case the user will be required to

correct the interference at their expense. The following techniques can be used to reduce

interference problems:

1. Disconnect the equipment from its power source to verify that it is or is not the source of the

interference.

2. If the equipment is connected to the same outlet as the device experiencing interference, connect

the equipment to a different outlet.

3. Move the equipment away from the device receiving the interference.

4. Reposition the receiving antenna for the device receiving the interference.

5. Try combinations of the above.

Product overview

D A N G E R

Chemical or biological hazards. If this instrument is used to monitor a treatment process and/or

chemical feed system for which there are regulatory limits and monitoring requirements related to

public health, public safety, food or beverage manufacture or processing, it is the responsibility of the

user of this instrument to know and abide by any applicable regulation and to have sufficient and

appropriate mechanisms in place for compliance with applicable regulations in the event of malfunction

of the instrument.

The SP-510™ Hardness Monitor continuously measures water softener levels to find hardness

breakthroughs based on softener exhaustion. The monitor is used in commercial and industrial water

applications. The monitor has an automatic control system that starts regeneration sequences with

the alarm circuit.

Hardness is measured at different levels as CaCO3 with the applicable indicator and reagent

solutions. A relay closes when the instrument measures a hardness value that is more than the trip

point. Refer to Figure 1 for the product overview.

Electrocution hazard. Always remove power to the instrument before making electrical connections.

D A N G E R

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the

document.

Install the instrument

Install this instrument on an indoor wall, away from direct sunlight.

• For a complete purge of the sample line during each cycle, install the instrument as close to the

sample point as possible.

• Leave sufficient clearance at the bottom and sides for tubing and cable connections.

Refer to Figure 3 and Figure 4.
