Shaft loading has an exponential effect on bearing life. The bearings will statistically last longer if you can limit shaft loading below the given values. Consider using the 5/8" shaft DuraCoder from AMCI if your shaft loading is expected to be greater than the values given below. Outline drawings for the 5/8" shaft DuraCoders start on page 17.

Connector Pinout Figure T1.11 shows the pin designations on the MS3112E-14-19P connector. AMCI sells a straight mating connector under the AMCI part number: MS-19. AMCI does not supply factory made cables for the Absolute Digital Dura- Coder because of the many possible configurations.

NSTALLATION Connector Pinout This pin controls which direction the shaft must rotate to increment the position Pin R: Direction Control – data. With this pin open circuit, position data increases with CCW rotation, looking at the shaft. Connecting this pin to Pin T, (DC Return), forces the position to increase with CW rotation, looking at the shaft. If you want CW increasing counts, you must connect pins R and T at the connector or at the end of a short extension cable.
Therefore, if the outputs are in their inactive state but the DuraCoder does not give any fault indication, check the power supply voltage and verify that it is within its acceptable range of 10.8 Vdc to 26.4Vdc. 20 Gear Drive, Plymouth Ind.

IAGNOSTICS Error Output The Error output is the same driver type as the position outputs, with an internal pull-up or pull-down resistor. Therefore, the “high” voltage is equal to the voltage that powers the DuraCoder. The output can sink or source a maximum of 500 milliamperes. It is designed to drive a typical PLC DC input. Figure T2.1 below shows how to wire the output to a typical DC input.
4) Releasing the Test Input for more than 325 milliseconds will take the unit out of test mode and back to normal operation. Repeating steps 1 through 4 will force the outputs to alternate between their logic “1” and “0” states. 20 Gear Drive, Plymouth Ind.

IAGNOSTICS Testing Sinking Output DuraCoders If the unit does not have internal pull up resistors, external pull up resistors or equivalent loads are required when testing sinking outputs. If this load is not present, a voltmeter may read that the output is active when it is in its inactive, high impedance, state due to leakage current through the output.
