    In case operators intend to use the positioner in other applications or conditions than specified, contact SAMSON. SAMSON does not assume any liability for damage resulting from the failure to use the de- vice for its intended purpose or for damage caused by external forces or any other external factors.
  • Page 7 Î Check with the plant operator for details on further protective equipment. Revisions and other modifications Revisions, conversions or other modifications of the product are not authorized by SAMSON. They are performed at the user's own risk and may lead to safety hazards, for example. Fur- thermore, the product may no longer meet the requirements for its intended use.
  • Page 8 Safety instructions and measures Servicing explosion-protected devices If a part of the device on which the explosion protection is based needs to be serviced, the device must not be put back into operation until a qualified inspector has assessed it accord- ing to explosion protection requirements, has issued an inspection certificate, or given the device a mark of conformity. Inspection by a qualified inspector is not required if the manu- facturer performs a routine test on the device before putting it back into operation. Document the passing of the routine test by attaching a mark of conformity to the device. Replace ex- plosion-protected components only with original, routine-tested components by the manufac- turer.

    Operation 7.2 Display Readings appear on the positioner display (see Fig. 33) immediately after the electrical pow- er supply (mA control signal) has been connected. Note LOW on the display indicates that the set point is lower than 3.8 mA. HIGH on the display indicates that the set point is higher than 22 mA. The bar elements indicate the system deviation that depends on the sign (+/–) and the value. One bar element appears per 1 % set point deviation. If the positioner has not yet been ini- tialized, the lever position in degrees in relation to the mid-position is indicated.
