4. Description of the electric-hydraulic crimping unit

4.1. Description of the components

The electric-hydraulic crimping unit type EK 120 plus is a hand
held tool and consists of the following components:

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 120 plus is equipped with a microprocessor which
indicated service intervals, internal checks and low battery
charges. 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:
- The diode will signal periodically a few times while the battery
(Pos.-No. 7) is being inserted into the tool. This indicates that
the electronic circuit board performed its self-test successfully.
- If the diode signals continuously after a crimping cycle for
approx. 20 sec. the battery is discharged and must be recharged
again.
- Does the diode signal periodically at the end of a crimping
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 an pressing cycle. The signal
indicates in this case the circuit opening by the electronic fuse.
A possible reason for that is that a pressing 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

5.1. Operation of the unit

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.
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 crimping head.
Afterwards the trigger lock (Pos.-No. 8) for the trigger (Pos.-No. 1)
must be released, which means that it is pushed down (Picture 2
Pos. B).
Prior to operating the unit the charging level of the battery (Pos.-
No. 7) should have been tested
detected by the flashing of the LED (Pos.-No. 6) for 20 s at the end
of a crimping cycle.
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 the trigger (Pos.-
No. 1) has to be locked with the trigger lock
(Pos.-No. 8) 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 120 plus has a large number of various dies (Pos.-No. 10)
available to crimp Klauke connecting material.
