With RST displayed, press the ENTER key on the Hand-
Held device or the SELECT button on the Safe-NET
display module. This will initiate the start up sequence in
the Safe-NET system. All operating parameters are read
from NV memory and the Safe-NET system begins
monitoring or control activity from a start up condition.
Note:
If an alarm condition was present at the time of RESET, the
alarm will be cleared and any associated alarm delay timers
are initialized to 0.
If the Safe-NET system is applied as a temperature
controller, the outputs may energize briefly during the start
up sequence.
NSEN
The NSEN parameter displays the number of
temperature sensors attached to the Safe-NET display
module. The Safe-NET display module scans the sensor
network during each reset cycle to locate and identify the
attached sensors. Subsequent to a reset action, the
number of sensors detected is displayed here. The number
of sensors is stored in NV memory and is continuously
compared to the number of responding sensors. In this
way failed or additional sensors are detected.
Setting / viewing this parameter is done in the SETUP
menu. After navigating to the NSEN sub menu item, the
display will cycle between NSEN and the current number
of sensors stored in NV memory.
While the NSEN value 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 0.
