Once 595 is displayed, press the ENTER key on the
Hand-Held device or the SELECT button on the Safe-
NET display module. The display will revert to cycling
between PASS and 595. This enables editing of critical
system parameters.
The user may now navigate the menu system and edit
parameters as necessary.
Note:
The password protected access remains active for 5 minutes.
Each time a new parameter is entered by pressing the
ENTER key on the Hand-Held device or the SELECT
button on the Safe-NET display module, the 5 minute timer
is restarted. After 5 minutes with no parameter entries, the
password value reverts to 0 and the password entry process
must be performed to regain access to critical parameters.
The SETUP menu can be navigated without a valid
password in a “view only”mode.
DSET
The DSET parameter sets the discharge air set point. This
set point is the control point when the Safe-NET system
is configured to provide temperature control of the
refrigerated fixture. The configurable range of the HIGH
and LOW alarm set points is centered around this
parameter’s settings.
When the Safe-NET system is applied as a temperature
monitoring device only, this set point has no effect other
than limiting the range of the HIGH and LOW alarm set
points.
Setting this parameter is done in the SETUP menu. After
navigating to the DSET sub menu item, the display will
cycle between DSET 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 set point.
