Stack alarm handling
This option stores the successive alarms in sequential order in a stack. When an
alarm is cleared, the next alarm image in the stack is presented on the alarm
monitor. Clearing an alarm takes place manually (see
manual reset
).
(The stack alarm can only be parameterised for a
single
alarm zone)
One of the three reset operating modes can be selected for each of the eight
possible alarm zones using the grey selection button.
The use of the
Stack alarm handling
reset mode is limited to a single alarm zone!

13.3 Activating / deactivating alarm lines (access code)
An alarm line access code can be used to prevent unauthorised persons switching
an individual alarm line or all the alarm lines to active or inactive.
The value ‘0000’ means that changes can be made without having to input an
access code.
Any other 4-digit value activates the access code as soon as the
OK
button has
been clicked to confirm.
The following functions are protected by the access code:
1.
Changes to alarm status (active/inactive) of the individual alarm lines.
Entry of digits ‘xxx’, function key ‘Alarm+’
Entry of digits ‘xxx’, function key ‘Alarm-’
2.
Entering or changing monitor cycles
Entry of digits ‘xxx’, function key ‘Zyk.Kx+’
Entry of digits ‘xxx’, function key ‘Zyk.Kx-’
