Operating Instruction Visatron VN 93
Technical Data
Suction System
The maximum number of sampling points for both systems
(header pipe and individual) =10. Suction pressure measured against atmospheric
pressure is 60 - 80 mm. The measurement is performed with a U-pipe manometer
on the measuring head. The U-pipe manometer is a component available on
request.
VN 115 / 93, VN 116 / 93
2 header pipes (22 x 2 mm) with branch pipes (10 x 2 mm) to the crankcase
compartments are to be installed for VN 115 / 93 and VN 116 / 93
VN 215 / 93
Individual pipes (14 x 2 mm) from each compartment to the OMD for VN 215 / 93
Sensitivity
VN 115 / 93
Alarm threshold 2% Opacity* (see brief description of the VN 115 / 93), adjustable in
10 levels from 0.5% to 25% Opacity. (1% Opacity corresponds to approx. 0.2 mg of
oil mist per litre of crankcase atmosphere; explosion limit 50 mg/l at ignition
temperature of approx. 500 C)
*Factory setting

Damage Check-start threshold 0.24% Opacity* (see brief description of the
VN 116 / 93), adjustable in 10 levels from 0.07% to 2.8% Opacity. Differential alarm
threshold 0.49% Opacity* (see brief description of the VN 116 / 93), adjustable in 10
levels from 0.14% to 5.6% Opacity. Safety alarm threshold 2.44% Opacity*
(see column 5, brief description of the VN 115 / 93), adjustable in 10 levels from
0.7% to 28% Opacity.

Power Supply
Electric Power Supply
Voltage: 24 V DC + 30/- 25%, 24 V battery or power supply unit
Note: In case of battery operation, provide a direct power supply from the battery
terminals to the VISATRON®- device!
Current consumption: max. 3 A, starting current 4 A, fuse 4 A semi time lag.
Electromagnetic compatibility: interference radiation EN 55011, resistance to
interference EN 50082/2 (interference immunity industry).
Drive Air for the Suction System
Suction vacuum measured against the atmosphere of 60 - 80 mm is required.
The measurement is performed with a U- tube manometer on the measuring head.
The U- tube manometer is a component of the service box (see accessories).
Air pressure required at the inlet of the jet pump approx. 0.6 bar. Air consumption
max. 1.0 Nm
3 / h (m 3 at atmospheric pressure). The drive air can be taken from the
pneumatic engine control system or from the starting air system. A pressure
regulation unit (see device list) can be delivered as an option for pressure reduction;
max. primary air pressure 12 bar (additional 30 bar pressure regulator is also
available).
