5.
Squeeze lever handle until the back of the main seal groove on the collet’s lines up with
the flat face of the front body. (See next section for pneumatic connectors)
Note: this location will change depending on thread size and fitting type.
6.
Apply 24V signal to the input line until the indicator begins to flash, about 2 seconds. This
will set point B on the graph above. Release the input line to record the second calibration
point.
7.
Release the handle.
8.
Slowly squeeze the handle through its entire movement. Confirm that the proper output is
achieved. Refer to the graph above to see the LED output.
9.
Re-install main seal.
ANALOG CALIBRATION (LEVER HANDLE AND PNEUMATIC):
A FasMate will not make a good connection if cross-threaded or short-connected. If short-con-
nected, the piston will sit near or at rest position, and the voltage will be smaller than the voltage
for a good connection. If cross-threaded, the piston will be over-extended, and the voltage will be
larger than for a good connection. To detect a good connection on an analog Sure Seal
TM
Fas-
Mate, the voltage must be above the short-connect threshold voltage (V
SC
) and below the cross-
thread detection voltage (V
CT
). This calibration procedure is a guideline for determining these two
voltages, but exact values depend on the user application.
The pneumatic FasMate cannot be slowly moved into position like the lever handle. It is either at
rest or fully extended when pilot pressure in introduced.
1.
Rotate the red, back body to the desired location and lock it in place with the set screw. It
can be backed out up to one full turn.
2.
Record the connector’s voltage at rest. The short-connect voltage (V
SC
) will be approxi-
mately 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.
Insert into test port and firmly hold it in place.
5.
Remove pilot pressure to de-energize 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 pro-
cess, 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:
1.
Loosen set screw.
2.
Unthread back actuator from front body.
3.
Lever version:
a.
Remove two screws securing PCA module.
b.
Remove/replace PCA module, spring, and actuator.
