72 Operating Instructions (Version 01/2012)
Lift ramp "T(x)xx.Lx" defines a lift ramp.
• T defines the time in s,
•
L defines the lift end position.
Press time shortening PTA "TxxxxX.PTA" defines the press time shortening ( P ress T ime
A utomatic). They must be entered directly after a press
command.
•
T defines the press time in s,
•
The PTA is a single-digit number and defines the press
time shortening in PTA × 10%.
The remaining time shown in the PTA command is
automatically shortened when the force adjustment has come
to a rest.
The first time shortening occurs after the pressure has not
changed for 35 s. As long the pressure remains constant and
the pressing time is not over, the remaining pressing time is
shortened after 5 seconds. Each change in force interrupts
the process. The current press time continues. The time
shortening then restarts after 35 s constant pressure, etc.
Hint:
You can string several time commands in a sequence; for
example, to ensure a safety press time. The pressure
remains steady between the time commands and does not
drop. You can also work with different pressures if you set
additional press commands between the times. You can also
apply pressure without a vacuum.
Active cooling "V.Cxxxx" defines quick cooling when the firing chamber is
slightly opened. Outside air is conducted through the firing
chamber by means of the vacuum pump.
Please note: To create a vacuum, firing chamber needs to be
closed (command L9).
• V defines the cooling air stream through the opening of
an additionally integrated flooding valve,
•
C defines the temperature in °C in the firing chamber.
Two sequential commands can be separated by a space for clarity.
The syntax is checked when you confirm your entry. If the entered command line contains an
error, then a warning appears. In this case, correct for the command line.
