7.9. Installing the Remote Indicator (optional)
Material number: 150998
Figure 50: Remote Indicator II
In compliance with IACS UR M10.11, it must be possible to read the operating and alarm status
of the oil mist detector remotely from the engine at a safe location (e.g. in the engine control
room). The Schaller Remote Indicator II can be connected as a monitoring device for this
purpose.
In the event of an oil mist alarm, Schaller Automation strongly recommends (as described in
IACS UR M10.7) not to approach the engine or carry out inspection work on the crankcase
until it has cooled down sufficiently after the engine has stopped. The oil mist alarm can only
be cancelled at the earliest after the level falls below the pre-alarm threshold.
The monitoring devices are connected via a RS485 bus line.
If a Remote Indicator II is used, the connection only consists of a two-point connection. When
the oil mist detector is delivered, the bus system is terminated with a resistor as standard. This
is integrated in the measuring head with switch (see Figure 51: Switchable termination
