Normal running of the unit

From the Main Menu move the cursor to the “Run Screen” item and
press ► “Enter”.

The unit will now enter the main operating mode.
By pressing ► “Enter” the mode will toggle between:
“OFF”:  Both Vacuum pump and Heater power sockets turned OFF,
regardless of limits set.
“ON”:  Both Vacuum pump and Heater power sockets turned ON,
regardless of limits set
“AUTO”:  Bothe Vacuum and Heater sockets will now power ON/OFF
based on the sensor readings to try and maintain a vacuum or
temperature in the set limits.
In the Auto mode the Blue LED will
be on and the Yellow and Red
LED’s will come on respectively
when the set  limits have been
reached.

When you find in the Auto mode
your vacuum pump cycles too often
for a short time the set limits may
be too close and you may have a
significant leak in the vacuum
bagging system.  During the first
couple of minutes frequent cycling
is normal as the trapped air is
sucked out.
The addition of a degas chamber or “vacuum reservoir” will help to stretch the time between pump
cycles and also ensure a more constant vacuum.

NOTE

:

In the running mode in both “ON” and “Auto” the vacuum pump and heater may switch off even when
the pressure or temperature levels are not reach during conditions when the pump or heater was
running for longer than the safety timers set in the “SETTINGS” menu.  By toggling between “ON”,
“AUTO”, “OFF” the safety timers will be reset and the vacuum pump and heater will operate again as
normal.
