Working with the Gas Alarm

Gas-Alarm Light

If the detected gas level reaches the gas-alarm level of 5 ppm, the monitor will detect this alarm condition
and turn ON the front panel ALARM light. The ALARM light will automatically turn OFF once the gas
level drops below 5 ppm.

Silencing a Gas Alarm

The monitor's internal audible alarm will also activate when the gas level reaches the gas-alarm level.
Pressing the SILENCE button while the alarm circuit is activated causes the internal audible alarm to
turn OFF for a period of time as set by the SILENCE function. The front panel ALARM light will continue
to flash, however, as an indication that an alarm condition still exists. The audible alarm will reactivate at
the end of the silence period if the detected gas level is still above the gas-alarm level.

Silencing a Fault Alarm

The FAULT light and audible alarm will automatically turn OFF after the cause of the fault has been
eliminated.

Working with System Faults

Functional Overview

If a system malfunction occurs (see Fault Code list on Page 15), the monitor will detect the problem and
turn ON the front panel FAULT light.
The FAULT light will automatically turn OFF after the cause of the fault has been eliminated.

Viewing the Faults Log

From the Data Display screen, press both Keypad Left and Right buttons at the same time to display the
first Function Menu screen. Next, use the Keypad buttons to move the arrow (>) until it points to the
FAULTS function, and then press the ENTER button to display the Faults Log screen.

The Faults Log screen shows the monitor's current fault status. If the fault
is still present when the FAULTS function is selected, then the current cause
of the fault is displayed along with the date and time it occurred. If the cause
of the fault has been cleared, then the Faults Log screen will show <0000>
along with the date and time the fault was cleared. Use the Keypad buttons
to scroll through the faults log. In the screens shown to the left, record #03
shows that a Sample Flow Fault (fault code <0800>) occurred on 07/11/15 at
08:17, while record #04 shows that the fault was cleared on 07/11/15 at 9:00.
The cause of the fault is identified by a numeric fault code. To convert the
fault code into a text description of the fault, first press the ENTER button
and then use the Keypad buttons to scroll through the display until the text
description of the fault appears. If the fault code is a combination of two or
more faults, then continue to use the Keypad buttons until all fault text
descriptions have been displayed. For example, the fault code <1800>
represents the combination of both a Sample Flow <0800> and a Purge Flow
<1000> fault as shown to the left.
The Faults Log can be cleared as described under the heading on Page 15.
