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
