Control Key Functions
[+] key If the information displayed
is read-only, pressing this key will
add it to the operator's menu. If the
information can be modified,
pressing this key will increase the
value without exceeding the
maximum possible value.
[-] key If the information displayed
is read-only, pressing this key will
remove it from the operator's menu.
If the information can be modified,
pressing this key will decrease the
value without exceeding the
minimum possible value.
[Previous] key Pressing this key
allows the operator to scroll up to
the previous information in the
current menu. Each menu is
looped, making it possible to scroll
from the first item in the menu to
the last item.
[Next] key Pressing this key allows
the operator to scroll down to the
next information in the current
menu. Each menu is looped, making
it possible to scroll from the last item
in the menu to the first item.
[Enter] key Pressing this key allows
the operator to validate a value after
modification.
[Cancel] key This key should be
pressed if a modified setting should
not be saved.
[Auto key] Pressing this key allows
the unit to be in Auto mode if it was
previously placed in Stop mode
with the [Stop] key. The unit cannot
be forced into Auto mode if an
external contact or the serial link
has stopped it. When the unit is
stopped by the remote interface
(Remote CLD), the local mode order
has priority.
[Stop] key Pressing this key allows
the unit to be in Stop mode. In
every case, and whatever the origin
(except a local stop), the stop order
and stop status have priority over a
run order. The stop generated is a
soft stop - the unit unloads before
stopping.
Whether a [Stop] or [Auto]
command will be accepted and
stored is based on the following
hierarchy:
1. Local Stop will always replace
Local Auto, Remote Auto, and
Remote Stop.
2. Local Auto will always replace
Local Stop, Remote Auto, and
Remote Stop.
3. Remote Stop will always replace
Local Auto and Remote Auto. It
will not replace Local Stop.
4. Remote Auto will always replace
Local Auto and Remote Stop. It
will not replace Local Stop.
Pressing the [Stop] key twice within
five seconds will result in an
Emergency Stop. The chiller will not
unload.
