Initial start-up
Connect the power cord (21)
with the power supply. Put the
On/Off switch (5) at the rear of
the furnace on position "I".
The language selection menu
appears on the display. Select
the language by means of the
F4 key and confirm by pressing
ENTER. Complete the selection
procedure using the function
key F1. After selecting the
language, the display shows the
EP600 logo. After that, the unit
conducts a self-test to check the
basic functions. The course of
the self-test is indicated by
means of a status bar. Once the
self-test has been completed
successfully, the preheating
phase will start. This phase
prepares the unit for optimum
temperature control. The
self-test and preheating phase
together usually take 30 min.
To reduce the moisture
in the press chamber
(stone lining) the
vacuum pump is
switched on during the pre-
heating phase, thus removing
the moist air.
As of Software Version V3.0 the
vacuum pump is kept on during
the complete pre-heating phase.
Once the preheating phase has
been completed, the unit is
ready for operation. The
'furnace selection' menu is
displayed to select whether the
furnace is used as press furnace.
After that, the main menu
appears on the display.
Important information
During the test of the
press drive, noise from
the press drive is
audible (approx. 2 seconds).
During the self-test, this sound is
normal. If this is not the case, a
technicalmalfunctionhas occurred.
Please refer to Chapter 8.
The power plug may
only be inserted into a
grounded socket. The
power cord must not
come into contact with the hot
furnace head and should be
protected accordingly.
The EP 600 is equipped
with a special
electronic device that
can bridge a power
outage of approx. 10 seconds.
The EP 600 Press
Furnace undergoes
extensive checks prior
to delivery. In the
process, the unit is subjected to
special test procedures. As a
result, the firing chamber may
exhibit slight signs of testing.
These signs show that the unit
has been tested. These checks
are important for quality
assurance.
