    1. COMMISSIONING 1 Commissioning The following chapter describes the commissioning step for DREHMO i matic actuators (for high temperatures) . NOTICE All explanations below relating to commissioning apply to actuators with clockwise closing valves. Clockwise output drive rotation corresponds to direction...

  • Page 4: Setting The Torque Values

    1. COMMISSIONING 1.1 Setting the torque values The torques are set by manufacturer as instructed according to the order. The torques are only indicated on the name plate if this is specifically requested. If no torques are specified on the order, the smallest possible torque is set by the manufacturer. The torque can be infinitely varied within the range given on the name plate by means of the torque scales affixed to the unit Use the setting screws for torque setting if torque signals are to be used (refer to fig-...

  • Page 5: Setting The Limit Positions

    1. COMMISSIONING DANGER Exceeding the maximum permitted torque A setting above the maximum permitted torque is not permit- ted. DANGER Regard the permitted torque range for additional gears, if used For actuators that are delivered with an additional gear or thrust unit by the manufacturer, the permitted torque range is written outside the housing cover.
