    Determine the correct installation situation and direction of fluid flow. iv) Spirax Sarco products are not intended to withstand external stresses that may be induced by any system to which they are fitted. It is the responsibility of the installer to consider these stresses and take adequate precautions to minimise them.
  • Page 5 1.9 Tools and consumables Before starting work ensure that you have suitable tools and / or consumables available. Use only genuine Spirax Sarco replacement parts. 1.10 Protective clothing Consider whether you and / or others in the vicinity require any protective clothing to protect against the hazards of, for example, chemicals, high / low temperature, radiation, noise, falling objects, and dangers to eyes and face.
  • Page 6 Customers and stockists are reminded that under EC Health, Safety and Environment Law, when returning products to Spirax Sarco they must provide information on any hazards and the precautions to be taken due to contamination residues or mechanical damage which may present a health, safety or environmental risk.
  • Page 7 1.17 Battery The Head unit is powered by a Lithium battery (Tadiran SL-2880). Handling considerations: Do not crush, pierce, short (+) and (-) battery terminals with conductive (i.e. metal) goods. Do not directly heat or solder. Do not throw into a fire. Do not mix batteries of different types and brands.

  • Page 8: General Description

    2. General product information 2.1 General description The STAPS wireless steam trap monitoring system has been designed to efficiently monitor and evaluate steam trap operation. It surveys the operation of the steam trap at regular intervals and identifies poor performance that can cause reduced plant efficiency and increased energy consumption. It can diagnose both failed-open steam traps that leak live steam, and those that have failed-closed or are blocked, resulting in waterlogging, leading to plant damage, product spoilage and health and safety concerns.
  • Page 9 3. Installation of the head unit assembly Note: Before actioning any installation observe the 'Safety information' in Section 1. The STAPS sensor includes the following parts: 1 off head and sensor assembly, including the head unit and sensor. Slot used for size of pipe: ½"...
  • Page 10 Installation - Is there sufficient room at the sensor at the top for the head to be mounted on the pipe? Lagging - Ensure that any pipe lagging in the area where the STAPS head is to be fitted is removed before fitting.
  • Page 11 3.1 Fitting the battery to the sensor head The head unit assembly requires a Tadiran SL-2880 3.6 V battery to function. Note: The head unit needs to be powered to be commissioned. However if the complete 'system' (receiver and DCS) is not in service, the battery should be removed until required. Failure to do so will considerably reduce battery life.

  • Page 14 3.1.4 Ensure all packaging is removed and fit battery into holder in the head unit. Ensure that the battery is in the correct orientation as per the orientation marker (+ to top). Note: Only use a Tadiran SL-2880 Lithium Thionyl Chloride 3.6 V battery.
  • Page 15 The LED response – number of flashes, follows the following pattern for each status that it is reporting; 1 flash is bad, 3 flashes are good. Time Function Action pressed < 0.2 s None The LED flashes green rapidly whilst the button is pressed. When the button is released the LED flashes red in sequence to indicate trap condition, battery status and RSSI.

  • Page 17 3.2.1 Fitting a remote mounted antenna Where the head unit is installed in an area with poor radio reception, an extension cable of up to 3 m length may be used to re-site the antenna and improve reception. Take the extension cable and attach one end to the antenna adaptor on the head enclosure as shown in Figure 17.
