The alarms generated by PlantWatch can be divided into 2 groups:
- the repeating of alarms generated by the instruments and received by PlantWatch via the serial network
- malfunctions or events diagnosed independently by PlantWatch (printer errors, modem errors, peripherals off-line, failed
download of logs, etc....)
The alarms deriving from the instruments are “produced” by PlantWatch based on a list of templates; each type of instrument
must have a corresponding template in the PlantWatch memory. For each category of controller (IR32, MPX,...), PlantWatch
decides the alarm variables (digital only) and, on each positive or negative transition, generates respectively an alarm event or
alarm over. The configuration template can only be created and edited using the 3ODQW:DWFK0DQDJHU configuration program.
The alarms are signalled instantly by the local devices, that is, displays, red LEDs and buzzers, while remote signalling devices,
that is, fax, SMS, data call to service centre and relay activation, are either delayed or not activated, according to the category
assigned to the alarm.
In fact, each alarm is entered immediately in the event log, while the remote device is called only if the alarm remains active for
a period longer than the delay time corresponding to the category that the alarm belongs to (see following paragraph).

Each alarm, according to how serious it is, can be attributed to a different category for remote signalling. The categories differ in
terms of the duration of the remote signalling delay:
&DWHJRU\ 'HIDXOWGHOD\ 'HOD\FRQILJXUDWLRQ
Local signal only ----
Immediate 1 minute fixed
Fast delayed 1 minutes using “PlantWatch manager”
Slow delayed 30 minutes using “PlantWatch manager”
The categories can only be assigned to each alarm generated by the Carel peripherals using the “PlantWatch manager”
configuration program. This also allows the category of the peripheral off-line alarms and printer error alarms to be modified.
$ODUP 'HIDXOWFDWHJRU\
Peripheral off-line Immediate (1 minute + detection time)
Printer not ready or RS485
printer module off-line
Immediate (1 minute + detection time)
Furthermore, there is another category of alarms which, due to their seriousness, can only be assigned to the immediate category
(1 minute):
VSDFH DYDLODEOH IRU YDULDEOH ORJ OHVV WKDQ : the memory available for saving the logs is almost full due to the failed
download in automatic mode at 30%
VSDFHDYDLODEOHIRUYDULDEOHORJHTXDOWRthe memory available for saving the logs is full; the new data is already deleting
parts of the log not yet saved by downloading or printing
SHULSKHUDO W\SH HUURU: this may arise due to an error in the configuration of the type of unit connected, for example, an IR
universal instead of an IR for refrigeration.
PRGHPLQLWLDOLVDWLRQHUURU: this alarm is generated when PlantWatch cannot initialise the modem 5 consecutive times. It may be
generated when starting PlantWatch, or alternatively when the modem is periodically re-initialised (every 20 minutes).
FORFNHUURU: this is a serious internal malfunction relating to the reading of the clock
IODVKPHPRU\HUURU: this is a serious internal malfunction relating to the operating parameters or the saving of the logs.
