9.3.2. General Controller (CTRL
STATUS) Screen
If the user selects the MODE field they will be able to
change the mode the zone is in. If the user

selects the ACT ZONE field, the current zone being
sampled can be changed.
The user can toggle the zone mode (in the
MODE
field) by pressing the right arrow key to activate the
field and using the “.” and “ — ” keys to select between
NORMAL , HOLD , and SERVICE . If the zone is set
to HOLD mode, the zone is continuously sampled.
Press the down or up arrow key to go back to the
STATUS OPTION screen. Your changes are saved
and data written upon scrolling back to the STATUS
OPTION screen.
Ux-MODE: NORMAL
Ux-STAT: <ZEROING:SAMPLE>
Ux-ALARM CNT:
Ux-ACT ZONE:
NOTE: x is the RLDS.
NOTE: When setting up multiple zones in
one area (such as a motor room), stagger
these zones as they enter the RLDS. For
example, if there are two motor rooms served by
one
RLDS, each motor room has three sensing zones.
Make the first motor room zones 1, 3, and 5, and make
the second motor room zones 2, 4, and 6. This will allow
the leak detection system to return to that area being
sensed more regularly.
If the zone exists in a location where air flow will

affect the dispersion of refrigerant, reduce the alarm
limits to a lower level than usual. This will allow for

dispersion of the refrigerant in the air.
