Front Panel User Interface

1.5.1 The "UP" Pushbutton

The "UP" pushbutton can be used to program the Mini-ICS Analyzer via the front panel. This
momentary push-button soft key is used to enter incremental information. Its function is menu-
driven.

1.5.2 The "DOWN" Pushbutton

The "DOWN" pushbutton can be used to program the Mini-ICS Analyzer via the front panel. This
momentary push-button soft key is used to enter decremental information. Its function is menu-
driven.

1.5.3 The "MODE" Pushbutton

The "MODE" pushbutton can be used to program the Mini-ICS Analyzer via the front panel. This
momentary push-button soft key is used to navigate the operational modes available through the
front panel. Its function is menu-driven.

1.5.4 7-Segment Alphanumeric Display

The 7-Segment alphanumeric display feeds back information from the Mini-ICS to the user via the
front panel. The primary purpose of the 7-Segment display is to show the Oxygen concentration
readout. It is also used for feedback information during modes of operation, Fault codes, and
operational mode indications, such as setup and calibration.

1.5.5 Normal Indicator LED

The purpose of the NORMAL Indicator LED is to inform the user via the front panel that the Model
Mini-ICS is measuring the concentration of the sample gas and updating the display and outputs
accordingly, and has not detected any Alarm, or Fault conditions.
1.5.6 O Alarm Indicator LED
2
The purpose of the O Alarm Indicator LED is to inform the user via the front panel that the O
2 2
Alarm and its associated relay are in active mode.

1.5.7 Low Flow Indicator LED

The purpose of the Low Flow Indicator LED is to inform the user via the front panel that the sample
gas flow from the process to the Oxygen sensor is below the mechanical set point of the flow
switch. Since Low Flow is considered a system Fault condition, when the Low Flow LED is active,
the Fault relay will also be active.

1.5.8 Fault Indicator LED

The purpose if the Fault Indicator LED is to inform the user via the front panel that at least one
system fault, other than the Low Flow Fault is active. Note that when the Fault Indicator LED is
active, the Fault relay will also be active.
