Once the desired setting 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
DSET and the new value.
Note:
Ensure all operators and service personnel are aware of the
units setting to eliminate confusion concerning case
performance.
DUTY
The Safe-NET system has an optional Relay Board
component that when attached, allows the Safe-NET
display board to control up to four outputs. The possible
controlled output devices are:
5)
Compressor (CMP)
6)
Evaporator Fans (FANS)
7)
Defrost Heaters (DHTR)
8)
Anti-Sweat Heater (ANTI)
The DUTY parameter determines the percentage of
ON
time for control of Anti-Sweat heaters if installed and
controlled by the Safe-NET display module. The control
period is 100 seconds. A range of 0 to 100 is possible
with 0 =
OFF CONTINUOUSLY
to
100 =
CONTINUOUSLY ON
. Adjusting this parameter can
improve energy consumption. However, a setting of
sufficient
ON
time is required to prevent condensation
from appearing on the fixture frame.
Setting this parameter is done in the SETUP menu. After
navigating to the DUTY sub menu item, the display will
cycle between DUTY and the current setting. While the
setting 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 change the setting.
Once the desired setting 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
DUTY and the new value.
Note:
Default Duty cycle setting is 0.
