4.2. Brief description of the important features of the unit

- The hydraulic unit incorporates an automatic retraction which
returns the piston into its starting position when the maximum
operating pressure is reached.
- The unit is equipped with a special brake which stops the
forward motion of the piston/dies when the trigger (Pos.-No. 1)
is released.
- The unit is equipped with a double piston pump which is
characterised by a rapid approach of the dies (Pos.-No. 10)
towards the connector and a slow crimping motion.
- The crimping head can be smoothly turned by 360° around the
longitudinal axis in order to gain better access to tight corners
and other difficult working areas.
- The EK 120U plus is equipped with a microprocessor which
indicates service intervals, internal checks, low battery charges
and switches off at high temperatures. It also shuts off the
motor automatically after the crimp is completed.

4.3. Description of the light diode display

This tool is equipped with a special circuit board incorporating
several important features to inform the user about the current
status of the unit. The diode (Pos.-No. 6) signals in the following
cases:
Signal Duration
a few seconds of
flashing
glowing for
20 seconds
flashing for
1
20 seconds (2Hz)
flashing for
2
20 seconds (5Hz)
20 sec. glowing
and flashing
intermittently

Remarks:
- Does the diode signal periodically at the end of a working cycle for
approx. 20 sec the unit must be returned to an authorised Service
Center for Service as soon as possible.
In case of an error the light diode display also signals periodically at
-
the end of a working cycle. The signal indicates in this case the
circuit opening by the electronic fuse. A possible reason for that is
that a cycle was performed with an incorrectly low battery. If the
signal occurs even after changing the battery there must be a
different error or a service is due. In these cases the tool must be
returned to the manufacturer or an authorised service center.

5. Remarks in respect of the determined use
Before starting any work on electrical appliances it must be
safeguarded that there are no live parts in the immediate assembly
area of the user. Is this not possible special precaution measures
working near live parts must be provided.
Prior to operating the unit the charging level of the battery (Pos.-No.
2
7) should have been tested . A low charging level can be detected
by the flashing of the LED (Pos.-No. 6) for 20 s at the end of a
crimping cycle.

5.1. Operation of the unit

Now you have to select the right dies (Pos.-No. 10) for the intended
application.
Attention
Don't operate the tool without dies.
The dies will be inserted sideways into the open crimping head.
When performing deep indent crimps the die-holder (Pos.-No. 8)
must be replaced against the connector cage of the deep indent
crimp set. On the opposite side the indenter must be set into the
adapter (KL-part # pp.13).
The crimping head should be turned into the desired position before
starting the crimping cycle. It is significantly easier to turn the
crimping head in a pressure free state.
The crimping procedure is initiated by actuating the trigger (Pos.-
No. 1 & Picture 2 Pos. A). The crimping process is defined by the
closing motion of the dies. During that process the connecting
material is positioned in the stationary half of the die whereas the
moving part of the die is approaching the compression point
The crimping process is terminated when the crimping force is
reached. After having completed the crimp the dies return into the
starting position automatically. Afterwards a second crimping cycle
can be initiated or the crimping procedure can be terminated.
Attention
After having terminated the crimping process
and prior to changing the dies remove battery to
avoid unintended use.
In case of error or emergency the dies can be returned into the
starting position by actuating the retract button (Pos.-No. 2 &
Picture 2 Pos. C).
Attention
The crimping process can be interrupted at any
moment by releasing the trigger.

5.2. Explanation of the application range

The EK 120U plus has a large number of various dies (Pos.-No. 10)
available to crimp Klauke connecting material.
