AT REST
EXTENDED WITH
PILOT PRESSURE
Pneumatic Control (FNP) with Analog:
1.
The pneumatic FasMate cannot be slowly moved into position like the lever handle. It is either
at rest or fully extended when pilot pressure is introduced.
2.
Record the connector’s voltage at rest. The short-connect voltage (
V
sc
) will be approximately
0.8V larger than the voltage at rest but may vary depending on your application.
3.
Activate connector by introducing pilot pressure.
Note the voltage output at max travel.
4.
Fully insert connector into test piece port and firmly hold it in place.
5.
De-activate pilot pressure to connector and verify that a good connection has been made.
Record the output voltage.
6.
Repeat steps 3-5 several times and record the connector’s voltage.
Use the distribution of
values to determine a cross-thread detection voltage (V
CT
) that is suitable for your
process, e.g. 2 standard deviations above the mean., or the largest voltage observed
for a good connection minus some safety margin.
7.
A good connection is indicated by the output voltage settling in the range between
V
sc
and
V
CT
8.
Once the range is determined a 24VDC signal may be applied to pins 2 and 5 to provide
red/yellow/green LED indication of connection quality.
*When using Analog, please note that the shielded cable improves noise (single termination): 0-
10VDC is used over operational range of the sensor.
Each time the connector is actuated, the threads can grip in a slightly different position. Therefore,
a range needs to be set during the calibration stage. It is suggested to try and short connect it
several times after the range has been set to ensure the range rejects bad connections. If the
connection falls outside of this range, the system can be setup to alert operators.
REBUILD/REPLACE ICON COMPONENTS:
Lever Version:
1.
Loosen set screw on red housing.
2.
Unthread red housing from front body.
3.
Remove two screws securing PCA module, discard module.
4.
Remove spring, and actuator and discard.
5.
Install new actuator, spring and PCA module.
6.
Apply Locitie 242 to the screws and tighten them to 5 in-lbs.
7.
Re-install red housing onto connector and secure set screw on housing.
