Hussmann ARL, Technician Manual, Page: 11 / 62

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.
MODIFYING SET POINTS
With the password active and the display reading
product temperature, use the SELECT button to
scroll through the menus. Once the display
reaches the
StuP
menu, use the UP button until
the display shows the parameter to be modified:
• To change the product low alarm set point,
press the UP button until the display cycles
between
PrLo
and the current product low
alarm set point.
• To change the product high alarm set point,
press the UP button until the display cycles
between
PrHi
and the current product high
alarm set point.
• To change the product alarm delay, press the
UP button until display cycles between
P-dL
and the current product alarm delay.
Once the desired menu item is displayed, press
SELECT button. The display cycles between the
corresponding menu item and the VALUE. Press
the UP button to increment the value or the
DOWN button to decrement the value. The value
of the parameter can be modified only within the
following specified ranges:
When the entered value begins flashing, press the
SELECT button to store the new value. The
display cycles between the new value and the
menu item. Within 12 seconds after button
activation, the display starts showing the product
temperature.
Replace top cover of the display module after
modifications are complete. Verify that alarm
LED indicators are on the left side as shown in
Figure 1 on page 1.
