Selecting alarm; entering new parameter values
After entering alarm programming, select one of the available alarms. Read the currently selected alarm
number on the upper display, and
rEAd
(read-only) or
chnG
(change possible) on the lower one.
Use
and
to select any of the 16 alarms. When the desired alarm number is shown on the upper
display, press
to strat the programming of the selected alarm. Alarm parameters are arranged
in a parameter tree. Move along the parameter tree and change values as described in chapters 6.4...6.10.
During the parameter programming for the selected alarm, the alarm number stays on the upper display.
After programming the parameters of the alarm, confirm that alarm parameter group by pressing
&
.
The controller stores the parameters in its permanent memory (see 6.12) and starts using the new values.
The device then waits for another alarm to be selected and its parameters reprogrammed.

Disabling an alarm
If the value of the parameter
uSE
is programmed to
no
, the function of the alarm is disabled and all its
functions are cancelled. To use the alarm again, change the parameter
uSE
value back to
YES
. This will
restore all other parameters of the alarm to their old values.

Enabling and using an alarm
If the value of the parameter
uSE
is
YES
, other parameters appear in the tree to allow the operator to
assign the alarm to some input, program its type and limits, and assign its output to some relay output.
