CNTN
The CNTN parameter sets the network address of the
Safe-NET control module to which Safe-NET display
modules, or the master network are connected.
This
setting has no effect when the Safe-NET system: is
applied as a temperature-monitoring device only; or,
does not require the Safe-NET control module; or,
is in a non-networked installation.
The Safe-NET system has an optional component known
as the control module. This device is implemented when
the Safe-NET system is applied where multiple evapo-
rators are temperature controlled by a motor-driven valve
such as an EEPR, a variable speed compressor or a single
liquid line solenoid (e.g. walk-in cooler). This application
requires multiple Safe-NET display modules to synchro-
nize their control and alarm activities and provide
temperature information to a central control device. The
Safe-NET display modules must communicate this
information via a network cable to the Safe-NET control
module. Accordingly, the Safe-NET control module must
be assigned a unique address in order to send and receive
alarm and control messages.
Setting this parameter is done in the SETUP menu. After
navigating to the CNTN sub menu item, the display will
cycle between CNTN and the current set point. While the
set point is being displayed, press ENTER on the Hand-
Held device or press the SELECT
button on the Safe-NET display module to allow editing
of the value. When the Safe-NET display module begins
flashing the value, use the UP or DOWN arrow keys on
the Hand-Held device or the UP /DOWN buttons on the
Safe-NET display module to increment or decrement the
value to the desired address.
Once the desired address is displayed, press the ENTER
key on the Hand-Held device or the SELECT button on
the Safe-NET display module to store the new value to
NV memory. The display will revert to cycling between
CNTN and the new value.
Note:
The Safe-NET system must be RESET for the new value to
take effect.
Factory default is
NONE
