5.2 Description of the essential features of the device
The punching device is equipped with a overrun stop, which stops the feed immediately after letting go of the control switch.
The cutting head can be rotated continuously around the longitudinal axis. This allows installations in inaccessible spaces.
A built-in white LED illuminates the workspace after activation of the control switch and turns off automatically after 15 seconds.. This feature
can also be switched off.
The compact, ergonomic shaped housing consists of 2 components: the grip area is particularly slip-free through its rubber coating and together
with the barycentric housing, the hand-held device is comfortable to hold and assists in fatigue-free application.
All functions of the device can be controlled with one control knob. Resulting in simple handling and improved support, in comparison to
two-button operation.
Li-Ion batteries are known for not having memory or self-discharge effects, providing the operator even after long breaks, always with an
operational device. In contrast to NiMH batteries, Li-Ion batteries weighs less, haves 50% more capacity and shorter recharge times
The oil used, is a fast biodegradable and non-water-endangering high performance hydraulic oil with the
Blue Angel
seal of aprovement. The oil
is suitable for very low temperatures, and has excellent lubricating properties.
The punching device is equipped with a microprocessor control, that for example switches the motor off after completing a stamping operation,
indicating maintenance intervals- and battery charge status, and performs an error-diagnostic.
5.3 Operating functions
A punching operation is triggered by operating the control switch (item 7). The electro hydraulic punching device type Powerlec Vario is equipped
with a special circuit, which switches the motor off automatically after a successfull punching process. The control switch (Item 7) must be pressed
continuously during the punching process. The device is equipped with a overrun stop that automatically stops the feed process after the control
switch is released. Through a single press of the reset slide (item 2), the
pressure ring returns to its original position.
5.4 Description of the automatic control
The Powerlec Vario is equipped with a microprocessor controller that controls the flow of a die-cut.
After a successfull punching process, i.e. when the stamp has cut the metal, the puncing motor turns off automatically. This serves as a safety function
for the operator and protects the punching tools. This safety function prevents that the punch touches the die base with full force, consequently dama-
ging the stamp, or in worst cases breaking the die apart.
5.5 Description of LED display
The LED display (item 3) in conjunction with control electronics, provide information on the status of the battery (item 5) and of the
device. In particular, the LED display lights up in the following cases:
