Preparing for Operation . NOTE The positioner will be equipped at the factory and delivered complete with the necessary options at the customer’s request. Options modules may only be retrofitted by our service technicians. The positioner must be assembled – especially in a moist environment – in such a way as to rule out freezing of the positioner axle at low ambient temperature. The operating keys must be covered to prevent liquid getting in. ! WARNING In the combination of components it must be ensured that only positioners and options modules are combined which are approved for the respective area of application. This applies especially for safe operation of the positioner in areas in which the atmosphere is potentially explosive (zone 1 and 2). The instrument categories (2 and 3) of the instrument itself and those of its options must be observed. In addition, you must always make sure that no water gets into an open housing or screw--type gland. This may be the case for example when the positioner cannot be finally assembled and connected immediately. It generally applies that the positioner may only be operated with dry compressed air. Therefore use the normal water traps. An additional drying unit may even be necessary in extreme cases. This is particularly important when operating the positioner at low ambient temperatures. Please set the purge air switch (on the valve block above the pneumatic terminals) additionally to the “OUT” position. Use a sufficiently rugged console (e.g. plate thickness > 4 mm with reinforcements) for rotary actuators and the mounting kit “linear actuator” or integrated connection for linear actuators. 3.3.1 Instructions for using positioners in a wet environment This information gives you important instructions for the assembly and operation of the positioner in a wet environment (frequent, heavy rain and/or prolonged tropical condensation) in which the IP65 degree of protection is no longer sufficient and especially when there is a danger that water may freeze. To prevent water getting into the instrument in normal operation (e.g. through the exhaust air openings) or the display being poorly legible, please avoid the unfavorable installation positions illustrated in figure 3-5. 38 SIPART PS2 Manual A5E00074631-03
Preparing for Operation Figure 3-5 Favorable and unfavorable installation positions If conditions oblige you to operate the positioner in a unfavorable installation position, you can take additional precautionary measures to prevent penetration by water. . NOTE Never clean the positioner with a high pressure water jet because the IP65 degree of protection is inadequate protection for this. The necessary additional measures to prevent penetration by water depend on the installation position chosen and you may additionally require: S screw--type gland with sealing ring (e.g. FESTO: CK –1 / 4–PK–6) S plastic hose approx. 20 to 30 cm (e.g. FESTO PUN-- 8X1,25 SW) S cable straps (number and length depends on local conditions) Procedure S S S S Connect the pipes in such a way that rain water which runs along the pipes can drip off before it reaches the terminal strip of the positioner. Check the electrical connections for perfect firm contact. Check the seal in the housing cover for damage and contamination. Clean and replace if necessary. Mount the positioner if possible so that the sinter bronze silencer faces downwards on the underside of the housing (vertical installation position). If this is not possible, the silencer should be replaced by a suitable screw--type gland with a plastic hose. SIPART PS2 Manual A5E00074631-03 39
