10. USER’S ABBREVIATED FUNCTIONAL TEST
NOTE: 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
your system is functioning upon receipt.
10-1. Procedures
Perform this abbreviated functional test prior to installation of the electronics and sensors in the
application fixture.
10-1a. Attach the power supply cable to connector J5 and apply power to the system.
10-1b. 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.)
10-1c. Slowly move the target through the sensor’s measuring range to check for a full
range of output for S3: 0Vdc to +9Vdc.
10-1d. Next: Check S1 for 0Vdc to –9Vdc.
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.
10-1e. Repeat the above test for sensor S4 @ +9Vdc and S2 @ -9Vdc. Axis 2 output is
pin 6.
10-2. If the output does not change during this test:
10-2a. Make sure you have power applied at the correct voltage: +14.5 to 16Vdc and
–14.5 to –16Vdc.
10-2b. Make sure the wiring to connector J5 is correct (see Figure 11).
10-2c. Make sure you are monitoring the correct channel for the sensor you are
checking: S3 & S1 = axis 1 (pin 4), S4 & S2 = axis 2 (pin 6).
Still no change: return the unit to Kaman Instrumentation for servicing.
