EM2
Operation
Power-up
Before applying power, make a final check of all wiring
for continuity, shorts, grounds, etc. It is usually best to
disconnect external alarms and other equipment from
the EM2 entrance monitor until the initial start-up
procedures are completed.
Operator Interface
All operator functions are performed from the
pushbuttons on the front of the panel. Below is a
list of the common key functions used for the LCD
operations:
Enter key is used to enter the Top menu, edit and save
configuration parameters and save changes while
exiting.
Escape key is used to go back to previous menu screen
or exit out of a field without saving changes.
Up/Down/Left/Right keys are used to navigate the
menu and field lists.
In some fields, the arrow keys can be held in to
dramatically increase the speed at which the number
increments/decrements.
Contrast
To adjust the contrast of the LCD, use the keys
from the Home screen or Status screen. The contrast
setting is shown on the Status screen.
Home screen
The Home screen of the LCD provides an at-a-
glance indication of the gas concentration, along
with gas type, unit of measurement, and alarm
status. The menu tables also allow for other units of
measurement, such as temperature, pressure, etc.
In cold temperatures, the LCD response time slows
down. The refresh rate will automatically slow down to
compensate for this to make it easier to read.
