Operation
After installation and commissioning, the idOil separator alarm system functions entirely
independently and does not require constant monitoring.
The idOil Solar is fully deactivated for most of the time, which means that it consumes very
little power. The device only starts at set measurement intervals to perform the sensor
measurements. Whe nequipped with 3G modem is starts also at listening intervals to
receive any possible setting commands and at reporting intervals to send measurement
values. The power consumption depends on the set measurement and transmission
intervals as well as number of alarms. More information about the low-power mode settings
is available in chapter
Commissioning
.
All operations are controlled by the idOil-30 Control unit, which is installed inside the idOil
Solar enclosure (see
System Components
).
The user can activate the device at any time by pressing the reset/test button briefly. This
activates the device for 30 seconds, after which it returns to low power mode. The device’s
WLAN network is activated when the reset/test button is pressed a second time. In this
case, the device stays activated for as long as an external terminal device is connected to
it’s WLAN network. The device returns to low power mode 5 minutes after the end of any
active WLAN connection by an external terminal device.
The following chapters describe operation of idOil Solar system through local display,
browser-based user interface and text messages.
7.1. Local display and alarms
Local display
The four-row local display in the front panel is normally off. You can activate the display by
pressing the reset button once, at which point the display shows the system status as well
as possible alarms and faults. In the event of an alarm, the type of the sensor that activated
the alarm is shown (high liquid level, oil or sludge). In addition to this, the display can be
used to show the customer information specified in the context of commissioning; company
and telephone number (not a factor setting).
Alarms
In alarm and fault situations:
The device measures sensor status only at the set measurement intervals (e.g. 10 min).
After the alarm delay (10 s):
The buzzer sounds an alarm and the display’s backlight flashes for 10 s, after which the
device enters power saving mode. The relay states are not changed.
In a level alarm
the sensor in the separator has detected that the liquid level being
monitored has reached the alarm limit (high liquid level, oil or sludge).
In a fault alarm
the control unit has detected a fault in the sensor circuit. The monitoring
covers the communication between the control unit and sensor as well as short circuits
and breaks.
