Column Description Range of Values
LL Alarm Priority Priority of the lowest limit; default value: 500 0...1000
LL Alarm
Acknowledgment
Required
Activated
The user must confirm that the lowest limit value
has been exceeded (acknowledgment).
Deactivate
d
The user may not confirm that the lowest limit
value has been exceeded.
Default value: Deactivated
Checkbox activated,
deactivated
Alarm Hysteresis
The hysteresis avoids that many events are continuously
created when the process value often oscillate around a limit.

NOTICE
Faulty event recording due wrong parameter settings possible!
Setting the parameters L Alarm Value and H Alarm Value to the same value can
cause an unexpected behavior of the event recording since no normal range exists
in such a case.
For this reason, make sure that L Alarm Value and H Alarm Value are set to different
values.
4.1.6 User Program
Which application function the PES should perform is specified in the user program. The
PADT is used to create and compile the project configuration with the user program, and to
load it into the processor module.
4.1.7 Starting the Processor Module
The processor module can be started as described below:
 Inserting it into a base plate supplied with operating voltage
 Switching on the operating voltage for the base plate in which the module is inserted.
The module's behavior while it is starting up depends on:
 Position of the mode switch (see
3.4.18)
 Existence of additional, redundant processor modules
 Existence of a valid project configuration (user programs included) in the non-volatile
memory
With the switch set to Stop or Run, the processor module checks if any other processor
modules exist
 If no other processor modules exist, the module starts operation alone.
 If at least one additional processor module exists, the module attempts to automatically
start operation using the configuration of the existing processor module(s). Safety-
related operation is maintained.
For more information on how to start up modules, refer to the HIMax System Manual
(HI 801 001 E).
The instructions specified in the Safety Manual (HI 801 003 E) must also be observed.
