2-1 <2. PRECAUTIONS> 2. Precautions 2.1 Transportation and Storage Before transporting the unit, it is recommended to fix the float with a card-board strip in the same way as when shipped from factory. Prevent foreign objects from entering the tube (e.g. by covering openings). To protect the unit and especially the tube’s interior from soiling, store it only at clean and dry locations 2.2 Installation Ambient temperature and humidity of the installation location must not exceed the specified ranges.
PAGE 14
2-2 <2. PRECAUTIONS> Check movability of the float (5)* by watching the pointer. The pointer should follow the movement of the float. If this is not the case, float and measuring tube (1;21) should be cleaned. Check the movability of the pointer by careful moving it with your fingers and watching whether it responds to the scale value. If it does not work properly, the mechanical display unit (14) must be changed. To avoid damage of the float and of the stopper do not use magnetic valves.

3-1 <3. INSTALLATION> 3. Installation 3.1 Installation in the pipeline The pipe has to be so stabilized that vibrations on the pipe are avoided. Additional recommendations can be found in guideline VDI/VDE 3513 sheet 3. If pollution of the metering tube may appear a bypass-pipe is recommended, which permits the removal (see. chapter 6 “maintenance”) of the Rotameter for cleaning without interruption of the flow.

3-4 <3. INSTALLATION> 3.2.2 Conductor connection with Quickon To connect the conductor, please observe in particular the following steps : - Strip the sheath to a length of approx. 15 mm (fig. 3-4) and slide the union nut (1), the cap (2) and the rubber seal (3) onto the conductor. 5 3 2 4 1 15 mm Fig. 3-4 F6.EPS F7.EPS Fig. 3-5 - Slide the rubber seal as far as the rim of the insulation and then slide the cap onto the rubber seal. This provides the strain relief for the conductor (fig. 3-5).
PAGE 19
3-5 <3. INSTALLATION> - insert the core ends into the feed through of the splice ring (fig. 3-6). In order to guarantee a clear assignment of the cores, the individual core feed thorough of the splice ring are numbered (1, 2,…). Fig. 3-6 - Cut off the projecting core ends. Make sure that the core ends are flush with the splice ring (5): they can protrude by up to 3 mm, but must not be too short. F8.EPS - Insert the prepared conductor into the QUICKON contact carrier (4).

<4. START OF OPERATION> 4-1 4. Start of operation 4.1 Hints on flow rate measurement The measured fluid should neither consist of a multi-phase mixture nor contain ferrite ingredients or large solid mass particles. The RAKD scale is adjusted to the state of operation/aggregation of the measured fluid by the manufacturer. If the state of operation changes, it might become necessary to establish a new scale.

5-1 <5. LIMIT SWITCHES OPTION /K1 TO /K10> 5. Limit switches (Option /K1 to /K10) The optional limit switches are available as maximum or minimum type switches. They are proximity switches according to EN 60947-5-6 (NAMUR). Maximal two switches can be installed. The option (/Wnn) includes the respective transmitter relay. These switches have been specified for hazardous area. However, the transmitter relay must be installed in safe area.

<6. SERVICE> 6-1 6. Service 6.1 Maintenance 6.1.1 Function test Checking free movement of pointer: - Remove housing cover (4 screws). - After deflecting the pointer by hand, it must return to measurement value. If the pointer pivots to different values upon repeated deflections, there is too much friction in the bearings. In this case, send indication unit to service. Checking free movement of float: - First, free movement of pointer has to be ascertained.

A1-2 A1.2.2 Diagnostic Response Time In case of a fault the limit switches will go to their safe fail state immediately. A1.2.3 Setup A setup of the flow meter is not required. Installation shall be done according to the manual. A1.2.4 Proof Testing The objective of proof testing is to detect failures within the flow meter that are not detected by the diagnostics of the flow meter.

A1-3 A1.2.6 Startup Time The flow meter will generate a valid signal within 0.5 seconds of power-on startup. A1.2.7 Reliability data A detailed Failure Mode, Effects, and Diagnostics Analysis (FMEDA) report is available from Rota Yokogawa with all failure rates and failure modes. Rota Yokogawa RAKD variable area flow meter is intended for use in a Low Demand Mode. Low Demand Mode means the average interval between dangerous conditions occurs infrequently.
