Introduction
EP46844:
Interface for second water temperature or oil
pressure gauge.
To operate a second water temperature or oil pressure gauge
(slave instrument) with only one (single) sensor fitted in the
engine block.
EP46845:
Interface for high coolant temperature warning
system.
To operate a warning lamp and/or buzzer for high coolant tem-
perature with only one (single) sensor fitted in the engine block.
EP46846:
Interface for low oil pressure warning system.
To operate a warning lamp and/or buzzer for low oil pressure
with only one (single) sensor mounted in the engine block.
EP412326:
Interface for warning system for full waste
water tank.
To operate a warning light and/or buzzer to activate indicating a
virtually full waste water tank, with a float fitted in the waste
water tank.
EP46847:
Interface for second water temperature gauge
with warning system for high coolant temperature warning
system.
For operating a second temperature gauge (slave instrument)
as well as a warning lamp and/or buzzer for high coolant tem-
perature with only one (single) sensor fitted in the engine block.
EP46848:
Interface for second oil pressure gauge with low
pressure warning system.
For operating a second oil pressure gauge (slave instrument) as
well as a warning lamp and/or buzzer for low oil pressure with
one (single) sensor fitted in the engine block.
With all warning system interfaces, the warning level can be set
on the interface.
The maximum current for a warning lamp and/or buzzer is
200 mA.
All interfaces are suitable for 12 and 24 Volts.

Installation
The interface can be fitted to the gauge after it has been mount-
ed in the dashboard. Note the connections to the gauge (draw-
ing 1).

Connection
Connect the interface as shown in the diagram.
Adjustment
The warning systems are set to give a visible/audible warning in
the following cases at 12 Volts:
- EP46845 and EP46847 : At a coolant temperature of 98
degrees C.
- EP412326 : When the waste water tank is virtual-
ly full.
- EP46846 and EP46848 : At an oil pressure of 0.5 Bar and
less.
If a different setting is required, or when the ship has a 24 Volt
ship's power supply, proceed as follows:
EP46845, EP46847 and EP412326:
- Switch off the supply voltage.
- Take the sensor wire off the 'SENSOR' connection and con-
nect a 500 Ohm potentiometer between the 'SENSOR' and -
(negative) connections (drawing 2).
- Turn the trim potentiometer on the interface to the right.
- Switch the supply voltage on and adjust the 500 Ohm pot-
meter so that the temperature is at the value you want the
alarm activated.
- Now turn the potmeter on the interface to the left until the
warning lamp and/or buzzer operate.
- Turn the 500 Ohm potmeter and check that the alarm switch-
es on at the correct temperature.
- Switch the supply voltage off and take off the 500 Ohm pot-
meter and reconnect the sensor wire.
EP46846 and EP46848:
- Switch off the supply voltage.
- Take the sensor wire off the 'SENSOR' connection and con-
nect a 500 Ohm potentiometer between the 'SENSOR' and -
(negative) connections (drawing 2).
- Turn the trim potentiometer on the interface to the right.
- Switch the supply voltage on and adjust the 500 Ohm pot-
meter so that the pressure is at the value you want the alarm
activated.
- Now turn the potmeter on the interface to the left until the
warning lamp and/or buzzer operate.
- Turn the 500 Ohm potmeter and check that the alarm switch-
es on at the correct pressure.
- Switch the supply voltage off and take off the 500 Ohm pot-
meter and reconnect the sensor wire.
