Superdew 3 WP Instruction Manual

Product catalog summary
UK & EU Declaration of Conformity
The Superdew 3 WP Dewpoint Hygrometer by Shaw Moisture Meters (UK) Ltd complies with the 2014/30/EU Electromagnetic Compatibility Directive and the 2014/35/EU Low Voltage Directive, adhering to standards EN IEC 61326-1:2021 and BS EN 61010-1 2010+A1 2019.
Unpacking
Inspect the package for damage and ensure all components are included: hygrometer, wall mount brackets, sensor, connecting cable, sensor holder, instruction manual, and pressure dewpoint calculator.
General Information
The Superdew 3 WP features a dual-function keypad, backlit LED display, selectable engineering units, AutoCal potentiometer for calibration, two alarms, 4-20 mA output, and RS485 capabilities.
Safety Information
Installation must be performed by qualified personnel due to hazardous voltages. The equipment is isolated per EN61010-1 standards, and the power supply must be protected by an external fuse and switch.
Installation
Mounting options include hook, DIN rail, or wall bracket. Ensure proper orientation and secure mounting. Wiring involves removing the terminal cover and connecting cables through specified glands, ensuring proper isolation and adherence to local electrical regulations.
Air/Gas Sampling System Installation
Ensure the sample is free from contaminants. Maintain a flow rate of 2-3 litres/min. The sensor measures changes in water vapour pressure, displayed as dew/frost point temperature.
Piping Installation and Components
The sample pipe should run upwards from the sample point. Key components include a sample isolation valve, filter unit, and sample tube. Pressure regulation is crucial, with specific configurations for atmospheric or full line pressure measurements.
Installing and Commissioning the Sensor
An initial purge of the sample loop is recommended. After purging, the sensor is installed, and a low-pressure purge is conducted. Equilibrium may take several hours to achieve.
Default Instrument Configuration
The instrument displays moisture content in °C dewpoint, with alarms set to trigger above the upper limit. The output span is set to 4-20 mA, covering -80 °C to 20 °C.
Programming the Superdew 3 WP
Numerical data entry involves selecting numbers using specific keys. The setup menu offers options for sensor range, output span, alarms, RS485 communications, password, and panel functions.
Normal Operation and Hotkeys
The Superdew 3 WP displays current moisture values, with alarm LEDs indicating conditions. Hotkeys allow review and alteration of alarm trigger points and displayed units.
Automatic Calibration
Calibration is intended for trained personnel and applies to sensor ranges up to 0 °C dewpoint.
Specifications
The Superdew 3 WP uses a SHAW Ultra High Capacitance Aluminium Oxide Sensor with various ranges covering dewpoints from -100 °C to +20 °C. It is CE and UKCA approved, with an accuracy of ±2 °C dewpoint and a resolution of 0.1 °C or 0.1 ppm(v). It operates between -20 °C to +60 °C.
Procedures
Calibration involves exposing the sensor to ambient conditions and adjusting the AutoCal potentiometer if necessary. Monitoring involves periodic inspection of the sample loop and filter elements.
Norms and Recommendations
The system should be operated in a clean environment. Routine maintenance is minimal, but malfunctions should be addressed by contacting the dealer.
Faults/Errors
If the sensor is short-circuited, the display will read 'Short'. An alarm level above the sensor range will display 'oVEr'.
Guarantee
Shaw products are guaranteed for two years, excluding damage from misuse. Faulty equipment must be returned for inspection before replacement or repair.
Electrical and Mechanical Specifications
The device complies with EN 61326:2021 for EMC. It has a warm-up time of 5 seconds and operates on 90 to 250 V AC or 24 V DC. The enclosure is IP65 rated.
Appendices
Includes setup menu flow diagrams, alarm hotkey flow diagrams, units hotkey flow diagrams, RS485 protocol details, and assembly diagrams.

There are several different ways to mount the Superdew 3 WP to the wall. Before proceeding, ensure that the product is mounted with the front panel facing horizontally, with all seals fitted including the back seal. On the rear of the enclosure there is a hole to accept a hook or screw head for hanging. The thickness of the enclosure here is 3.7 mm therefore, the minimum gap recommended for the slot is 4 mm.

C. Wall Mount Bracket A wall mount bracket kit is supplied with the Superdew 3 WP. The two brackets mount to the rear of the enclosure. The enclosure can then be fixed to the wall from the front using M5 screws or similar. Fit the two brackets to the top of the enclosure at each corner. The terminal cover must be removed to mount the product to the wall. Use M5 screws or similar to mount the product at the four mounting points shown below.

4.2 Instrument Wiring Ensure that the power is disconnected prior to removing the terminal cover. Remove the terminal cover by loosening the two screws. The cover should lift off while still retaining the screws. For working on the power connection, there is an additional High Voltage Guard which can be removed using the single screw in the corner. This screw will be retained with the guard. The Main PCB connectors will now be visible. Insert cable of the appropriate diameter through the cable gland. The cable gland on the left for the sensor connections is M16 type and the recommended cable...

4.3 Power Supply The Superdew 3 WP can be powered by either a 90-250 V AC or 24 V DC supply. Connect the required supply cable to the appropriate terminals as shown in fig. 1.1. The AC power supply should be between 90-250 V AC @ 50/60 Hz. The power supply wires are retained by screws. Ensure that the exposed section of wire is fully inserted and that no loose strands are exposed. You must ensure: All connector screw clamps are screwed down tightly to prevent movement of the cable. Once the connector clamps are screwed down tightly, all cable glands are tightened to prevent movement of the cable....

5.0 Installing the Air/Gas Sampling System The Piping Installation Schematic diagram (see section 5.1) shows all components that could be used in a dry gas measurement application. Not all the items shown will be required for every installation. Care should be taken to ensure that the sample presented to the measuring sensor is not contaminated with any other component that will damage, contaminate or affect the sensor in a way that will impair the system accuracy. It is strongly recommended that the sample should not contain particulate matter, oil or other heavy hydrocarbon condensate. If these...

a. The sample pipe should not be on the upper surface of the horizontal pipe or on a vertical section of pipe wherever possible. b. The sample tube should run continually upwards from the sample point. If this is not possible then an inspection port or drain tap should be installed at the lowest point in the system.

1. Sample Isolation Valve - This is a recommended item as it allows access to the sample system without interrupting the main process line. 2. Filter Unit - A filter unit is recommended when the samples are likely to contain particulate matter. Ifthe air/gas sample contains heavy hydrocarbon condensate, the filter must be of the coalescing type with a drain. The filter unit should be positioned as close to the sample point as practical. 3. Sample Tube - This should be stainless steel for dry air or gas applications but copper or carbon steel can be used where wetter gases are to be measured....

6.0 Installing and Commissioning the Sensor It is advisable to carry out an initial purge routine of the sample loop before installing the sensor. This is to remove the possibility of sensor damage on start up. Refer to the Piping Installation Schematic in section 5.1. Open the inlet isolation valve slowly until a small flow of air/gas (at atmospheric pressure) flows through the inlet pipe work to the sensor holder, exhausting through the sensor entry port of the sensor holder. Allow this purge to continue for about 15 - 20 minutes to remove any residual moisture from the sample pipe work and...
