Calibration
WARNING: Maintain clear distance from all moving parts .
Calibration Procedure
The calibration procedure below will calibrate the Danfoss
crimp machine to the original factory setting. While new
machines are calibrated at the factory and will be ready
to use upon receipt, this procedure should be followed
if the crimp machine has been disassembled or has had
components replaced. The procedure requires the use of an
FT1307-200-M180 die cage and a -4 (TTC/Z Series) and a -8
(TTC/Z Series) fitting.
NOTE: While in the calibration mode, follow the instructions
precisely, and press the keys deliberately. If a mistake is
made, the calibration procedure must be started over by
turning the machine off and then on again.
1. Insert an FT1307-200-M180 die cage.
2. Press the STORE and ENTER buttons simultaneously, and
then release. Both button lights will now illuminate and will
remain lit until the calibration procedure is finished.
3. Input the value of “210” using the keypad.
4. Center a TTC/Z Series -4 fitting (without a hose) in the die
cage, holding the socket or fitting in place with a pencil or
other suitable tool. Crimp the socket by pressing the crimp
switch or footswitch until the machine retracts by itself,
indicating a completed cycle. Allow the die cage to retract
to the “full retract” position.
5. Using a micrometer, measure the crimp diameter. The
preferred method is to use the average of the four pairs of
indentations.
6. Locate the crimp diameter in Table A, below. Using the
keypad, enter in the three-digit DISPLAY reading that
corresponds to the crimp diameter.
Note: If your crimp diameter falls between the numbers
shown in Table A, simply determine or interpolate the
DISPLAY reading, since the numbers are a direct ratio.
7. Input in the value of “610” using the keypad.
8. Center a TTC/Z Series -8 fitting (without a hose) in the die
cage, holding the socket or fitting in place with a pencil or
other suitable tool. Crimp the socket by pressing the crimp
switch or footswitch until the machine retracts by itself,
indicating a completed cycle. Allow the die cage to retract
to the full retract position.
9. Repeat steps 5 and 6 at left, using Table B for the -8 socket.
10. After the three-digit DISPLAY reading in Step 9 is entered,
the machine will automatically exit the calibration mode.
Calibration Example
Crimp a TTC/Z Series -4, and measure the four crimp
diameters around the socket. For example, the diameters
measure .692, .693, .694 and .694 inches, to obtain the
average diameter, add the four diameters, and divide that
sum total by 4.
(.692+.693+.694+.694) = 2.773 = 0.69325 = 0.693
4 4
(round to nearest thousandth)
Look at the crimp diameter column in Table A and find your
average diameter. If it falls between two numbers, as this
one does, interpolate the desired setting. In this case, you
would enter 193. If your crimp diameter is .690, you would
enter 190; if it is .697, you would enter 197.
Crimp a TTC/Z Series -8, and measure the four crimp
diameters around the socket. This time, let’s say that the
diameters measure 1.113, 1.115, 1.114 and 1.115 inches.
Obtain the average diameter by adding the four diameters
and dividing that sum total by 4.
(1.113+1.115+1.114+1.115) = 4.457 = 1.11425 = 1.114
4 4
(round to nearest thousandth)
Look at the crimp diameter column in Table B and find your
average diameter. If it falls between two numbers, as this
one does, interpolate the desired setting. In this case, you
would enter 614. If your crimp diameter is 1.110, you would
enter 610; if it is 1.119, you would enter 619.
