1 Basic safety instructions

1.1 Requirements for the personnel

‣Installation, commissioning, operation and maintenance of the measuring system must

only be carried out by trained technical personnel.

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

specified activities.

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

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

and must follow the instructions they contain.

‣Measuring point faults may only be rectified by authorized and specially trained

personnel.

Repairs not described in the enclosed Operating Instructions may only be carried out

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

1.2 Designated use

CYA112 is designed as a modular assembly system for sensors in open basins, channels and

tanks.

Any other use than the one described here compromises the safety of persons and the entire

measuring system and is not permitted.

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

1.3 Workplace safety

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

• Installation instructions

• Local prevailing standards and regulations.

1.4 Operational safety

‣Before commissioning the entire measuring point, make sure all the connections are

correct. Ensure that electrical cables and hose connections are not damaged.

‣Do not operate damaged products, and safeguard them to ensure that they are not

operated inadvertently. Mark the damaged product as defective.

‣If faults cannot be rectified, the products must be taken out of service and secured against

unintentional commissioning.

1.5 Product safety

The product is designed to meet state-of-the-art safety requirements, has been tested and

left the factory in a condition in which it is safe to operate. Relevant regulations and

European standards have been observed.

2.4 Certificates and approvals

Explosion protection

The stainless steel version of the CYA112 assembly (CYA112-*A21*2**) is suitable for use

in hazardous zones 1 and 2.

The ATEX directive 94/9/EC does not apply because the assembly has no potential ignition

source. Accordingly, it is not designated according to ATEX. Potential equalization must be

implemented as described in the chapter "Installation conditions".

If sensors have accessible metallic surfaces, these surfaces have to be connected to the

potential match according to the corresponding operating instructions.

3Installation

3.1 Installation conditions

Install the assembly on a place with enough free space around it so the sensor cannot get

damaged.

When installing the assembly in a fixed position, make sure that it can be easily accessed and

maintained. The immersion pipe has to protrude the holding point by at least 100 mm

(3.94")

a0011037

Fig. 1: Holding point (illustration without splash protection cap)

The grounding has to be done on-site. All conductive parts have to be connected to each

other.

For use in hazardous areas:

• The immersion pipe side of the assembly has to be conductively connected to the

corresponding holder or fixing.

• When the assembly is fixed via chain or mounting bracket a separate conductor for

potential match is needed beside the measuring cable.

• If sensors have accessible metallic surfaces, these surfaces have to be connected to the

potential match according to the corresponding operating instructions.

3.2 Installation instructions

3.2.1 Mounting the stainless steel parts

You have to screw the pipes together finger-tight (without any gaps). The threads are

lubricated and provided with an O-ring.

3.2.2 Gluing the PVC parts

PVC assemblies up to 1200 mm (47.2") in size are delivered as ready-to-install units

and do not have to be glued.

Where required, cleaning cloths and glues form part of the scope of supply.

Glue the PVC parts as follows:

1. Clean the surfaces to be glued (exterior pipe end, sleeve or internal angle piece) with the

cleaning cloth.

2. Allow the cleaned surfaces to dry for approx. 5 minutes.

3. Apply an even film of glue to the surfaces to be glued (sleeve first, then the pipe).

4. Join the parts within one minute (push together until the stop).

5. Remove the excess glue.

6. Allow the glued parts to harden for at least 5 minutes.

3.2.3 Mounting the sensor

Preparatory steps:

1. Screw or glue the connecting bracket onto the immersion tube.

2. Where necessary, screw the sensor adapter onto the connection bracket.

Mount the sensor as follows:

1. Guide the sensor cable through the immersion tube.

2. Where necessary, connect the sensor cable to the sensor.

3. Screw the sensor into the adapter or into the connection bracket. To prevent the sensor

cable from twisting, rotate the assembly and not the sensor.

4. Shorten the tip of the rubber plug so that it suits the cable diameter.

5. Fit the rubber plug onto the sensor cable and press it onto the immersion tube.

6. Route the sensor cable downwards in a loop (do not bend) and fit on the splash

protection cap. The splash protection cap is fixed by the lip of the rubber plug.

3.2.4 Fixed installation of the assembly on a transverse pipe

Prerequisite: The sensor is already mounted.

The cross clamp is mounted in such a way that one closed side points to the center of

the basin while the other closed side points upwards.

Mount the immersion tube as follows:

1. Adjust the clamps on the cross clamp (å4).

2. Slide the cross clamp over the immersion tube. Make sure that the closed side of the

cross clamp is at the top (å3).

3. Mount the multifunctional clamp ring (funnel-shaped side facing upwards) on the

immersion tube above the cross clamp. The multifunctional clamp ring acts as an anti-

slip lock.

4. Attach the cross clamp, along with the immersion tube, to the transverse pipe. Make

sure that the closed side of the cross clamp faces the basin (å3).

5. Align the assembly and the holder.

6. Tighten the clamp screws finger-tight (finger-tight corresponds to 13 Nm (9.6 lbf ft)).
