13 Alarms
13.1 Operational or alarm signal
The digital signals can be chosen as either
operational or alarm signals.
A operational signal can be defined as non-critical,
i.e. a signal, that one want to be registered.
Typically a signal, that indicate if a pump is running
or not.
An alarm signal is on the other hand a signal, that
normally is inactive and only will be active, when a
fault condition occurs. A thermal cutout on a pump
is a typical alarm signal.
Alarm signals has memory and reset, i.e, when the
alarm signal becomes non-active, it will be
memorized that the signal has been active. The
"active" state must be reset by the user before a
new active signal can be accepted as an alarm
signal. For both types of signals applies that both
the number of active conditions and the time frame
within the signal has been active, will be
registered.
13.2 Alarm calls
If the function "Alarm - call by telephone" is
selected (see section 6.5), the Comtroller 702 will
start a call routine by making a call attempt to the
first number in the phone list, then the next number
etc.
There will be a pause between the call attemps.
See also section 10.
When dialing to a telephone modem, it will be the
SCADA terminal that will be responsible for
resetting the alarm and stop the call routine.
When dialing a pager or telephone, the call routine
must be stopped with a telephone call back to the
Comtroller. This procedure will not reset the alarm,
only stop the call routine. If an alarm occurs during
the call routine, the call routine will not stop, i.e.
the new alarm will not be reported until the next
call succeeds.
The telephone list is not used if the RS485 port are
used for communication (via radio modem,
Powerline modem owned lines etc.). All alarm calls
is sent to the Master communications unit.
13.3 Reset of alarms
When a digital alarm signal becomes active, it will
be displayed in function menu F 8.1. Function
menu F 8.2 will display the input number and type
causing the alarm, the corresponding alarm desig-
nation, the immediate status of the alarm and the
time when the alarm was set.
When a digital alarm signal become active, the
alarm status will be shown in funtional indication
F8.1. In functional indication F8.2 will be shown:
the type of alarm, the time of start and a symbol
indicating the status. The symbol flashes until the
alarm is registered which makes the symbol
permanently lit. The symbol stays lit until the alarm
signal is no longer active, then the signal disapears
and the stop time will show instead of the start
time.
To reset an alarm directly from the Data Transmit-
ter keyboard, the display must show indication
F8.1. With the arrow keys the alarm to cancel is
chosen then press ENTER. The symbol will then
stop flashing and the alarm is registered.
An alarm can also be reset from the SCADA sta-
tion via modem. This is carried out via the
communications protocol. If you do not wish to
have more calls on the account of a specific alarm
signal, it can be left unregistered, and there will be
no more calls, even if the signal changes from not
active to active.
If the alarm is not registered, and a further 9 alarms
occur, i.e. the unregistered alarm becomes no 10
the alarm will be cancelled.
