CONTROL PANEL DESCRIPTION
Control Figure # Item # Use
The user interface is a membrane panel with two indicator bars, two digital displays and
two pushbutton actuators. It is located on the upper sloping surface of the front fascia of
the ModulyoD. Through this interface the user will switch on and off and moving refrig-
eration and vacuum. Figure 5, Figure 2 and Table 1 (below) locate and describe, in
detail, the function of each item.
1.2.1.3 USER INTERFACE

To switch refrigeration system on and off.
To show temperature of the condenser chamber in °C.
When the temperature of the condenser chamber is equal to
or higher than ambient temperature, ‘rt’ is displayed, which
stands for ‘room temperature’.
The lamp is on when the refrigeration system is on.
The temperature indicator bar is a multicolored display
designed to indicate operating status from a distance. Green
indicates a temperature at or near minimum (approximately -
40 °C.). Amber bars indicate temperatures progressing from
approximately -40° to -7°. Red bars indicate temperatures pro-
gressing from -7° to ambient (see Figure 6, page 8).
To switch vacuum pump on and off if the pump is plugged
into auxiliary power outlet of the ModulyoD (see Section 3.5,
page 15).
The lamp is on when the vacuum pump is on.
To show absolute pressure in the condenser chamber.
Readings start when pressure is less then 50 mbar and are
in millibars down to 1.0 millibar. When the vacuum pressure
drops below 1.0 millibar, the pressure will then be displayed
in micro-bars. When pressure is above 50 mbar, ‘Hpr’ is dis-
played, which stands for ‘High pressure’.
The vacuum indicator bar is a multicolored display designed
to indicate operating status from a distance. Green indicates
a
pressure at or below 1mbar. Amber bars indicate
pressures progressing from approximately 1 to 13 mbar.
Red bars indicate pressures progressing from 13 to 52
mbar, (see Figure 7, page 8).
To switch the ModulyoD on and off.
