OPERATION • When auto-tuning is executed, control is stopped, and ON/OFF output switching (if the output type is relay output or voltage output) or output switching between the manipulated variable upper and lower limits of the currently selected PID set (if the output type is current output or position- proportional output) is repeated several times.

    Chapter 9. & TROUBLESHOOTING MAINTENANCE 9 - 4 Motor Adjustment is Impossible There are two ways of wiring a motor to the DCP32: wiring for direct motor rotation and wiring for reverse motor rotation. When wired for direct motor rotation, the motor rotates in the clockwise (CW, ) direction as DCP32 output increases.

    Do not throw used batteries into fires or dispose at the user site. Return used batteries to Yamatake Corporation or your dealer. If you touch components inside the DCP32, touch a grounded metal object to discharge any static electricity from your body.
  • Page 182 Handling Precautions • Replace with the lithium battery set (model No.: 81446431-001). The lithium battery set can be ordered from Yamatake Corporation. • When removing or mounting the RAM board or battery connectors, do not use metallic tools. Doing so might short-circuit electrical circuits.
  • Page 183 Chapter 9. MAINTENANCE & TROUBLESHOOTING ⑥ Place the body on a desk or flat surface so that the side on which the battery is installed is facing up. ⑦ Remove the battery from its gray holder. ⑧ Remove the RAM board (approx. 3 cm x 8 cm) with the battery still connected to the board.
  • Page 184 Chapter 9. MAINTENANCE & TROUBLESHOOTING ⑫ Fit the battery into the gray holder so that the battery cable is above the RAM board. Gray holder ⑬ Insert the body into the case. Do not exert excessive force if the body cannot easily fit into the case. Also, make sure that the boards mounted on the body are not loose or twisted.
