4.4 Change of Direction for Rising Signal (discrete units).
4.4.1 Move actuator as in Section 4.1.1.
4.4.2 Remove positioner cover and undo the three M4 screws retaining the red retransmit plate, as shown in Figure 7. Loosen the central coupling screw sufficiently to pull the coupling complete with the retransmit assembly off the actuator connection.
4.4.3 Remove the internal indicator from the coupling and withdraw the coupling from the retransmit plate.
4.4.4 Pull the two halves of the coupling apart sufficiently to allow the cam to be withdrawn from its location peg. Flip the cam over and push it back into the slot between the two coupling halves and locate it back on the peg.
4.4.5 Refit the coupling to the retransmit plate and slide the internal indicator over the top of the coupling.
4.4.6 If when the coupling was removed, the collet was left behind on the actuator connection, remove the collet from the connection and push it into the lower half of the coupling ensuring that it locates in the semicircular 'pip' and tighten the clamping screw by two turns. Place the coupling and retransmit plate back on the actuator connection such that the cam follower is approximately half way up the rise of the cam and pull back the spring lever with the other hand and tighten the coupling clamping screw. Re-tighten the retransmit plate retaining screws.
4.4.7 The internal changeover block is not effective with a discrete positioner. The changeover of the airflow path is achieved by swapping over the external connections. It may also be preferred to turn the positioner through 180 degrees to simplify the external pipe runs.
4.4.8 The adjustment of zero and range is completed as in section 4.2.
5. MAINTENANCE AND TROUBLESHOOTING.
The AP positioner is designed for a long life with very little maintenance required if it is supplied with clean, dry oil free air, as recommended in section 2.3.
When the positioner lid is removed, take care not to remove all grease from the lid/coupling seal. If it does need replenishing then ensure that a synthetic grease is used as a mineral oil grease will adversely affect this seal.
If, however, any of the parts do need replacement because of adverse conditions, then refer to Kinetrol Ltd for spare parts together with any instructions for replacing and resetting.
The following trouble shooting guide should help in the unlikely event of a problem with the performance of the unit. If problems persist, contact your local Kinetrol distributor or Kinetrol Ltd for further advice.

2.安装
提供的定位器有直接安装在Kinetrol旋转气缸上，或者可以直接安装在Kinetrol旋转气缸上或非直接安装型。非直接安装型可通过安装附件安装在任何90度的旋转气缸上。若定位器是可以直接安装在旋转气缸上，2.1和2.2部分可以跳过。型号050—140为定位器型Kinetrol旋转气缸（可与定位器直接安装）。
2.1直接安装到定位器型Kinetrol旋转气缸（无角度反馈）
注：有角度信号反馈设备中请参阅6.1
2.1.1移动旋转气缸的叶片到中间位置，其输出方头如图1所示。这样在放置定位器连接套时可以有效的预防发生错误。（如带有复位弹簧的旋转气缸就没有必要这样做，因为不会产生混淆）。
2.1.2拆下定位器盖子，松开两个固定红色角度刻度板的M4螺钉，拆卸连接套，如图2所示。
