Function Screens

The Function screens are used to display stored data and to set up the monitor.

From the Data Display screen, press any Keypad button to display the first Function Menu screen. Next, use

the Keypad buttons to move the arrow (>) on the display until it is next to the desired function, and then press

the ENTER button to select that function.

Once a function has been selected, use the Keypad to scroll through the displayed data or to change a

parameter associated with that function. Press ENTER to save newly entered parameters. Press the QUIT

button to return to the previous screen without saving.

Note that if no buttons are pressed within 90 seconds after selecting a function, the monitor returns to the Data

Display screen.

PPM LOG – Contains records of the last 200 measurements. Each record

shows the measurement’s date, time, and ppm level. Note that the interval at

which the measurements are logged is determined by the LOG INT function.

Use the Keypad Up and Down buttons to change the record number by a

factor of 1. Use the Right and Left buttons to change the record number by a

factor of 10. Press QUIT to return to the previous screen.

In the example on the right, record #025 shows that a level of 425 ppm was

measured on 11/07/08 at 15:35.

Note that the PPM Log can be cleared as described in Section Clearing the

Stored PPM Log, Alarm & Fault Data (Page 20).

ALARMS – Contains records of the last 30 alarm events, with the monitor’s

most recent alarm being shown when the Alarm screen is first displayed.

After 30 events have been recorded, the newest record overwrites the oldest.

Each record displays either LEAK, SPILL, or EVAC including the date and

time the alarm occurred. Use any of the Keypad buttons to scroll through the

other alarm records. Press QUIT to return to the previous screen. Refer to

Gas Alarms (Page 18).

Note that the ppm levels at which alarms occur are set using the LEAKLVL,

SPILLLVL, and EVACLVL functions.

In the example on the right, record #03 shows that a spill event occurred on

11/10/03 at 15:06.

FAULTS – Contains records of the last 30 fault events, with the monitor’s

current fault status being shown when the Fault screen is first displayed.

After 30 events have been recorded, the newest record overwrites the oldest.

Each record lists an event’s numeric fault code plus the date and time the

fault occurred. Use any of the Keypad buttons to scroll through the other

fault records. Press QUIT to return to the previous screen. Refer to System

Faults (Page 18).

In the example on the right, record #15 shows that a Purge Flow Fault

<1000> occurred on 11/10/08 at 12:37.
