During the inhibit condition, the channel card will continue to read the
gas sensor reading, however, no action is taken in the event of an
alarm condition being exceeded.
c. A1 - Red LED
The A1 LED indicates that the preset first level gas alarm has been
exceeded. This alarm will not function in the event of either a fault or
inhibit condition being active.
d. A2 - Red LED
The A2 LED indicates that the preset second level gas alarm has
been exceeded. This alarm will not function in the event of either a
fault or inhibit condition being active.
e. A3 - Red LED
The A3 LED indicates that the preset third level gas alarm has been
exceeded. This alarm will not function in the event of either a fault or
inhibit condition being active.Reset/Select Push-button
The front panel RESET/SELECT push-button provides four functions
depending upon how it is operated:
a. Alarm Reset
The RESET/SELECT push-button, when pressed momentarily, resets
any latched alarm, non active alarms, faults, warning or information
messages, clears the display peak reading indicator and will
acknowledge an update if such a condition is present.
Note: 'Non active alarms' describe the occasion where the alarm condition
has cleared but the alarm is still indicated due to latched
information. For non-latched setups the indicated alarms will clear
automatically when the alarm condition clears.
b. Channel Select
The RESET/SELECT push-button, when pressed for approximately
1.5 seconds, selects the control card for operations controlled from
the Engineering Card.
c. Extended Reset
The RESET/SELECT push-button, when pressed continuously for
five seconds:
i. Clears the channel maximum and minimum gas readings.
ii. Resets any active short term (STEL) and long term (LTEL)
exposure alarms clearing the timer to zero.
iii. For active time delay functions, activates any relay with
impending trigger and clears any relay being held.
d. Channel Deselect
The RESET/SELECT push-button, when pressed momentarily while
a control card is selected, deselects the control card from the
Engineering Card functions.
Note: The control card may also be deselected by pressing the key
