UAx
User alarm x (x=1..8)
User-defined alarm, as specified by parameters of menu M25.
22.2. Alarm properties
Various properties can be assigned to each alarm, including user alarms (
User Alarms
, UAx):
Alarm enabled
- General enabling of the alarm. If the alarm isn't enabled, it's as if it doesn't exist.
Retained alarm
- Remains in the memory even if the cause of the alarm has been eliminated.
Operating mode
– Operating modes where the alarm is enabled.
Global alarm 1 -2 -3
- Activates the output assigned to this function.
Step disconnection mode –
Defines whether and how the capacitor steps must be disconnected when
the alarm is present. OFF = no disconnection, SLOW = gradual disconnection, FAST = Immediate
disconnection.
Slave disconnection
mode – Defines, for Master-Slave applications, if when this alarm arises, the
disconnection is extended to all the step of the system (GENERAL) or only to the output of the
interested panel (LOCAL).
Inhibition
- The alarm can be temporarily disabled by activating an input that can be programmed with
the
Inhibit
function.
Modem call
– The alarm will be signalled remotely by sending a modem call under the conditions and
modality defined in modem parameters.
No LCD
- The alarm is managed normally, but not shown on the display.
Delay time
– Time delay in minutes or seconds before the alarm is generated.
