Operating Instructions
Entering a Number into the DISPLAY
1. Turn the power control switch below the keypad to the
ON position. The DISPLAY will illuminate to show that
the power is on.
2. Press the ENTER button. (The green light next to the
ENTER button will illuminate.)
3. Press three number buttons. (If more than five seconds
elapse between pressing the number buttons, the
DISPLAY reverts back to its previous setting.) After the
third number is pressed, the DISPLAY will remain and
the green light next to the ENTER button will turn off.
4. The ET4040 is now ready to crimp to the DISPLAY
setting.
Storing a Number from the DISPLAY as a Preset
1. Enter a three-digit number as described in the procedure
above.
2. Press the STORE button. (The green light next to the
STORE button will illuminate.)
3. Press and hold down any one of the 10 numerical buttons
for three seconds. (After three seconds, the green light
next to the pressed button will illuminate, indicating that
the DISPLAY has been stored to that button.)
Recalling a Preset into the DISPLAY
1. Make sure that the STORE and ENTER lights are off. (If
one is on, it will go off in five seconds if the keypad is left
untouched.)
2. Press the numeric button that has the stored setting for a
given hose and fitting style. That setting will then be seen
in the DISPLAY, and the light next to the numeric button
will illuminate.
Programmable Retract Stop*
1. Using the Crimp/Retract switch, place the cylinder in the
position where you want it to stop during retraction.
2. Press and hold the ENTER button until the green light
next to the button turns off (approximately three seconds).
The cylinder will now automatically stop retracting at this
position until another position is set or until the crimp
machine is shut off.
Note:
Pressing and holding the RETRACT switch will allow
the cylinder to fully retract. This will not change or erase the
programmable retract stop.
Note: Turning the crimp machine off and back on erases the
programmable retract stop position.
Adjustable Backstop (Figure 4)
1. Turn off the power to the machine.
2. Insert the die cage.
3. Loosen the thumbscrew on the backstop.
4. Place the fitting against the locator cone. Pushing it
too hard will compress the spring, which will affect the
accuracy of the position.
5. Slide the backstop to the desired position.
6. Tighten the thumbscrew.
7. Turn the power on.
* In order to reduce cycle time this feature allows for limiting
retraction of the cylinder. This is particularly helpful when
assembling multiple hose assemblies.
