The HACCP module uses some parameters from the plug-in instrument and its own parameter for the alarm recognition algorithm,
and produces a set of variables for recording the
+$ and +) events if these occur. It also features parameters for setting the clock
and entering up to eight defrost events at programmed times.
All the parameters can be displayed and modified using the
display and the buttons on the connected plug-in instrument.
The parameters can be accessed using the t parameter on the
plug-in instrument; when displaying the parameters some
segments of the left-most digit are used as indicated in the
figure.
The display and modification procedures are the same
indicated in the paragraph on accessing and modifying the t
parameters of the RS485 serial module.

This is read directly from the value set on the instrument.
$+YDOXHRIWKHKLJKWHPSHUDWXUHDODUPWKUHVKROG
This is read directly from the value set on the instrument. Together with the
6HW3RLQW it determines the value of the temperature
threshold for the detection of alarms
+$ and +) (respectively high temperature and power failure alarms).
Threshold =
6(7$+.
Warning:
$+ = 0 disables the detection of the alarms.
$G9DOXHRIWKHWHPSHUDWXUHDODUPGHWHFWLRQGHOD\
This is read directly from the value set on the instrument. It is used together with parameter
WU in the HACCP module to determine
the value of the delay in recognising the
+$ alarm event.
