Loading and unloading die cages

To load the die cage, press and hold the RETRACT switch
until the crimp cylinder reaches the "full retract" position
and stops. The die cages may be inserted or removed in
this position (See Figure 1). Note: To minimize cycle time
during normal operation, the Danfoss FT1390 crimp machine
can be programmed to stop retracting before it has fully
retracted. This reduces the crimping cycle time. The die
cage may not be able to be removed. Pressing and holding
RETRACT will always bring the cylinder to the full retract
position. See detailed instructions on page 6.
Caution: Figure 2 shows a die cage that is installed
improperly. When inserted properly, the die cage is flush
against the pressure plate. If the die cage is at an angle to
the pressure plate, lift up and realign properly.
Operating the keypad (Figure 3)
1. The DISPLAY shows the three-digit setting that will
determine the crimp diameter. The DISPLAY number itself
is a relative number, not a crimp diameter. The ratio of
crimp diameter change to the DISPLAY change is 1 to 1.

Operating Instructions

For example, if you crimp a fitting at a setting of 250, and
the crimp diameter is .014 inch too large, you will need to
decrease the DISPLAY by 014 to (250-014) = 236. A display
of 236 should produce the correct crimp diameter.
2. The STORE button is used to store the DISPLAY reading in
any of the 10 numbered keys. The green light next to the
STORE button will illuminate when you are working in the
STORE mode.
3. The ENTER button is used to put any three-digit number
into the DISPLAY. The green light next to the ENTER button
will illuminate when you are working in the ENTER mode.
4. The numbered keys have two functions:
a. In the ENTER mode, their numeric value is put into the
DISPLAY.
b. In the STORE mode, they act as 10 different memory
locations in which to store a DISPLAY setting.
