4.4.7
Activating the Interfering Gas Suppression (IGS)
The IGS Mode offers a mode in which interferences between R600a as the
refrigerant and Cyclopentane, Isopentane as well as any mixtures of the two will be
suppressed.
In this mode, the Ecotec E3000 will automatically differentiate between these three
gases and should compensate properly for levels of foaming agents not exceeding
50 g/a with an error of less than 1%.
To enable the IGS mode, choose R600a as the refrigerant and go to the mass menu
line. Press enter and toggle through the available masses for R600a until IGS is
displayed in the mass line item as illustrated in
Notice:
If the IGS mode is enabled, only one additional gas can be added to the list
of gases to be detected. If the IGS mode for R600a is enabled with more
than two gases being activated at this time, other gases (starting with the
highest gas number of 1 to 4) will be disabled automatically so that only two
gases are left activated.
Notice:
For R600a in IGS mode and R134a as the second gas please chose mass
position 83 for R134a as otherwise there will be interference between the
foaming agent and R134a.
Notice:
The IGS function should require almost no maintenance.
However, if you should notice repeating false alarms when using the IGS
mode, an adjustment of the IGS function may be required as described in
Chapter
.
4.4.8
Setting up a user-definable gas
For setting-up a user-definable gas please go to the
GAS
/
TRIGGER
submenu and
press the
USER
GAS
button.
In the opening sub-menu a list of five user definable gases will be displayed. For each
gas a user library position number, a user-definable name, a mass position,
normalization factor and the molecular mass is listed.
Please go to the gas you would like to set-up and press the
EDIT
button. In the
EDIT
USER
GAS
submenu please go to the appropriate line item you want to modify by the
use of the up and down buttons and press the
EDIT
key.
