PD-L
The PD-L parameter sets the alarm delay in minutes for
the product temperature simulator temperature. In the
event that the sensed temperature of the product
simulator exceeds the pre-set high temperature alarm
setting for the product simulator temperature for a
period equal to or greater than the PD-L setting, the
alarm is signaled. This is true for low temperature alarms
as well. There is only one time delay associated with all
product simulator temperature alarms.
Setting this parameter is done in the SETUP menu. After
navigating to the PD-L sub menu item, the display will
cycle between PD-L 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 increment or decrement the value to
the desired 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
PD-L and the new value.
Note:
The HIGH and LOW alarm settings are limited to +/– –16
deg F from set point. Setting the set point will not modify
the current alarm settings.They must be set independently
to ensure proper alarming.
A product simulator temperature sensor must be installed
in order to enable associated alarm functions.
