Operation

After installation and commissioning, the idOil separator alarm system functions entirely
independently and does not require constant monitoring.
The alarm information can be connected to automation systems through relays.
All of the system's connections and functions are described in the figure below and in more
detail in the following sections.

Local display and alarms

Local display
The device features LED lights for indicating alarms and faults.
Alarms
In alarm and fault situations:
The indicator lights for alarm and/or fault situations are switched on.
After the alarm delay (10 s):
The buzzer lets out an alarm sound.
The relays are switched to the alarm position. Relay 1 is de-energised in an alarm
situation and relay 2 is de-energised in a fault situation. The relays are of the failsafe
type, which means that they also enter the alarm state when operating power is lost.
The alarms can be divided into two groups: level and fault alarms.
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.
The indicator lights are used to indicate the status of the control unit and sensors. The
section below presents the operation of the indicator lights, buzzer and relays in various
situations:
