10.0 USER’S ABBREVIATED FUNCTIONAL TEST
This is not a calibration or installation procedure. This unit is factory calibrated, and installation
guidelines are in the next section. This is simply a check to make sure the system is functioning
upon receipt.
Perform this abbreviated functional test prior to installation of the electronics and sensors in the
application fixture.
Attach the power supply cable to connector J5 and apply power to the system.
While monitoring the system output, place an aluminum target within 0.015” (15N
sensor) or 0.020” (20N sensor) of sensor S3. It is preferable this step be accomplished
using a fixture to hold the sensor and to control target movement. However, carefully
hand holding and moving the sensor or the target will be sufficient for this check. (See
Figure 11 for power and output connections at J5. The output for sensor S3 and S1
[axis 1] is at pin 4.)
Slowly move the target through the sensor’s measuring range to check for a full range of
output for S3: 0 V to +10 V.
Next: Check S1 for 0 V to –10 V.
Note:
This will not be a linear output and you may get an output with the sensor as much
as 15 or 20 mils away from its target. That is OK since this check is only to confirm that
the system is working.
Repeat the above test for sensor S4 @ +10 V and S2 @ -10 V. Axis 2 output is pin 6.
If the output does not change during this test:
Verify correct input voltage: +14.5 to 16 V and –14.5 to –16 V.
Verify correct wiring to connector J5 (reference Figure 11).
Verify sensor connection, and output connection to the correct channel for the sensor
being checked:
S3 & S1 = axis 1 (pin 4),
S4 & S2 = axis 2 (pin 6).
Still no change: contact Kaman Precision Products.
