General
The RC-Z2514 4-arbor crimping pliers are for crimping the machined crimp contacts in the list below. The pliers may
only be used if they are in technically perfect working order and are only to be used for the purpose described in the
operating instructions. With this crimping tool, the user is able to check the pliers at intervals he defines himself, and
can calibrate them, if necessary. To increase the process reliability for the user, the pliers have wear monitoring. This
lets the user know when the tool wear has exceeded a defined range.
The settings of the crimping pliers have been calculated based on the
withdrawal forces stated in DIN EN 60352-2 and by using a reference
conductor.
Depending on the conductor used, the required
settings of the crimping pliers can differ from the values stated.
Procedure
• Switching on/off: The device is switched on/off by pressing the
"ON/OFF" button.
• Mode function: The "MODE" button is used to select the display
functions in mm or in inches, or the selector positions from 1 – 8 in
acc. with MIL 22520. Use the enclosed gauge to press the "MODE"
button as often as necessary to select the desired display:
Setting the crimping parameters / crimping operation
• Please refer to the enclosed setting matrix for the crimp arbor and
locator settings for the contact to be crimped.
• Loosen the clamping screw (condition when delivered).
• The crimping dimensions (crimping depth of the crimp arbors) are
set by turning the adjustment knob until the digital display shows the
required value. Please note that a larger crimping dimension must
always be selected than that to be set, e.g. select 1.2 mm and adjust
down to crimping dimension 1.0 mm.
• Depth settings clockwise reduce the crimping dimensions, while
counter-clockwise increases the crimping dimensions.
• Lock the crimping dimension setting using the clamping screw.
• Lift the locator at the side and turn to set it to the position defined in
the setting matrix. Insert the crimp contact as far as it will go into the
recess provided. The locator moves the crimp contact to the exact
position.
• Insert the prepared cable as far as it will go into the crimp contact in
the pliers and close the pliers tightly until the trigger block is unlocked.
Open the pliers and remove the crimped contact.
Do not crimp on the gauge or other similar objects to avoid
damage to the pliers. Avoid crimping solid materials (e.g. steel)
having a hardness greater than 35 HRC.

Changing the battery
The service life of the battery for the digital display is approximately one year, depending on how often it is used. To
change the battery (type CR2025, 3 VOLT), the battery holder is pulled out so that the battery can be removed and
exchanged. Before inserting the battery,
make sure you set the pliers to the stop at the lower setting point
.
How to further proceed is described in the section
"Calibrating the reference value".
Dispose of used batteries at
approved recycling centers.
Calibrating the pliers
The crimping pliers may only be calibrated by authorized skilled
personnel, since improper calibration can lead to incorrect
crimping.
• Adjust the crimp arbors to a setting dimension of 1 mm: Using the
adjustment knob, set the crimp arbors so that the enclosed gauge
can move between the crimp arbors without play. Please note that a
larger gauge dimension must always be selected than that to be set,
e.g. select 1.2 mm and adjust down to gauge dimension 1.0 mm.
• Keep the "ON/OFF" button pressed and press the "MODE" button
using the gauge. Keep the "MODE" pressed for at least 5 seconds.
Release the "MODE" button after 5 seconds and then the "ON/OFF"
button.
• The digital display automatically jumps to the gauge value 1.0 mm.
The pliers are adjusted and ready for the crimping parameters to be
set.
Wear monitoring
Every tool is subject to wear, even when used as intended. This wear is tolerable within certain limits and is
compensated during each calibration. Press the "Mode" button for 10 seconds (range: 8 to 15 s) to call up the current
tool status and to display the numerical output on the pliers. The following values are output consecutively:
• Serial number – current wear value – position value of the lower stop of the unworn pliers (fixed value, specific to
pliers) – number of previous calibrations carried out.
The mechanical stop at the lower setting point serves as a reference value for calculating the current wear value.
The value is permanently stored in the tool memory and cannot be changed.
Every time the battery is changed,
calibration must be carried out using this reference value.
To do this, follow this procedure:
Calibrating the reference value
• For preparation, the battery must be removed.
• Open the pliers.
• Turn the adjustment knob to the stop at the lower setting point (turn counter-clockwise;
see figure) and leave it there.
• Insert battery; "CAL" appears on the display to prompt you to calibrate.
• Adjust the pliers with the gauge (see also section "Calibrating the pliers").
• Keep the "ON/OFF" button pressed and press the "MODE" button using the gauge.
Keep the "MODE" pressed for at least 5 seconds. Release the "MODE" button after 5
seconds and then the "ON/OFF" button.
• The digital display automatically jumps to the gauge value 1.0 mm.
• The pliers are adjusted and ready for the crimping parameters to be set.
Troubleshooting
The 4-arbor crimping pliers reach their wear limit after about 50 thousand crimping
cycles. When this limit has been exceeded, the error message "E1" is output to the
display. Here, when pressed, the display cyclically switches between the set crimp value and the message "E1", and
then shows "E1" permanently.
Maintenance and repair
Unauthorized changes to or unintended use of the manual crimping pliers excludes the liability of the manufacturer for
any damage resulting from this. The manual crimping pliers must be clean and in good order before starting work. Any
residue from the crimping process must be removed from the crimping jaws and locator. The joints must be lubricated
regularly with a light machine oil and protected against dirt. Please ensure that all bolts are secured with circlips.
Repairs to the 4-arbor crimping pliers may only be carried out by the manufacturer of the pliers.
