(5ppm) and the alarm threshold 1 to 14ppm (4ppm). Only
if a residual oil content of 15ppm (5ppm) is exceeded for
at least 2 seconds, an alarm message to the engine
control room is activated. Alarm 1 must be set lower than
alarm 2.
In principle, three control states are possible:
a) Sample point falls below the limit value of 15ppm
(5ppm) set for alarm 2 and sample point falls below the
limit value of (14ppm (4ppm)) set for alarm 1.
Operator without adsorber, cleaned water is guided
outboards.
Voltage is applied to the solenoid valve of the 3-way valve
(pos. 58). The 3-way valve (pos. 58) guides the water
bypassing the adsorber. Voltage is applied to the 3-way
valve (pos. 57) and guides sample water from the sample
point upstream of the adsorber to the oil alarm monitor
OMD. Voltage is applied to the solenoid valve of the 3-way
valve (pos. 23). The 3-way valve (pos. 23) guides the
water outboards.
The display of the control system indicates:
b) Sample point exceeds the limit value of 15ppm (5ppm)
set for alarm 2 and sample point falls below the limit value
of (14ppm (4ppm)) set for alarm 1.
Operator with adsorber, cleaned water is guided
outboards.
No voltage is applied to the solenoid valve of the 3-way
valve (pos. 58). The 3-way valve (pos. 58) guides the
water through the adsorber. No voltage is applied to the 3-
way valve (pos. 57), it guides sample water from the
sample point downstream of the adsorber to the oil
monitor OMD. Voltage is applied to the solenoid valve of
the 3-way valve (pos. 23). The 3-way valve (pos. 23)
guides the water outboards.
The display of the oil separator control indicates:
c) Sample point exceeds the limit value of 15ppm (5ppm)
set for alarm 2 and sample point exceeds the limit value of
(14ppm (4ppm)) set for alarm 1.
Operator with adsorber, cleaned water is guided back to
the bilge or the bilge water tank.
No voltage is applied to the solenoid valve of the 3-way
valve (pos. 58). The 3-way valve (pos. 58) guides the
water through the adsorber. No voltage is applied to the 3-
way valve (pos. 57), it guides sample water from the
sample point downstream of the adsorber to the oil
