2.2 CONFIGURATION OF ThE SYSTEM
The system configuration pages are to set up control
parameters (date, time, language, etc.) as well as
to set up injection related parameters such as closing
duration after injection signal, prolonging of the
injection signal, etc.
To access the configuration page, select the SYST
function shown on white background.
Press the Validate key.
The following is displayed: these are the machine
parameters.
Default Factory Settings
Command for closing is held to all valve gates
after the injection signal has dropped
This is the time between the command and the
moment position control of the pin is made
(valid if option is purchased)
Prolonging the duration of the injection signal
2.2.1 DURATION OF ThE CLOSING
SIGNAL AT ThE END OF ThE INjECTION
CYCLE
This is the time the closing command is sent to all
valve gates when the control cabinet is switched
on or when the injection signal drops. The default
value is set at 1 second. Set 0 to disable this function.
2.2.2 DELAY BEFORE POSITION CONTROL
(OPTIONAL)
This is to set a response time between the
electrical command sent to the solenoid valve and
the confirmation of the pin position by the limit
switch.
2.2.3 PROLONGING OF INjECTION SIGNAL
This function extends the injection signal by a
certain time (t1) in order to command the valve
gates for a longer period of time. When set at
0, and as soon as the injection signal drops, a
command for closing is sent to all valve gates.
Using this function can delay the command
for closing by a certain time when the injection
signal drops. The delay is adjustable in 1/100 sec
(see graph 3.1). Valve gate commands can be
programmed during this time.
