Alarm Activation and Functions

6-1. Gas alarm activation

A gas alarm is activated when detected gas concentration reaches the preset alarm setpoint.

NOTE

•

The alarm setpoint (first alarm and second alarm) is factory-set. The setting values can be changed

in the maintenance mode (P.30).

•

Although the alarm delay time (standard: 2 seconds) prevents false alarm activation, the delay can

be turned off in the maintenance mode (P.30).

Display operation

<Concentration Display>

In case of over the detection range (Over Scale), "∩∩∩∩" is displayed on the LCD.

<During Power-on>

The LCD is continuously displayed.

<Alarm Display (ALM1: Yellow Backlight), (ALM2: Red Backlight)>

The alarms have two levels. The yellow or red backlight lights up when the respective alarm setpoint

value is reached to or exceeded. (Default: Backlight is off)

Contact activation

When gas concentration is at or above the alarm setpoint value, the contact is activated. After the gas

concentration falls below the alarm setpoint value, the contact activation resets automatically.

Measuring ranges of 0-2000ppm / 0-5000ppm / 0-10000ppm have a 50 ppm hysteresis.
