2.2 COMMISSION TABLE
1 Check if a siphon breaker (air vent) is necessary and
has been installed
2 Open the seawater inlet valve and check all water
connections. Check if the strainer is installed on or
just above the seawater level.
3 Check if the exhaust system is properly installed.
Check maximum length of exhaust hose, diameter of
exhaust hose, position of the water lock, maximum lift.
Also check the minimum required height of 24” (60
cm) above sea level of the exhaust loop (goose neck).
4 Open the seawater outlet valve and check all water
connections.
5 Check the AC cables and the grounding.
6 Check if an AC breaker is installed before or after the
power source selector. When there is only a circuit
breaker, use it to disconnect the generating set from
the grid.
7 Check all DC connections, check if the battery switch/
circuit breaker is closed.
8 Open the fuel valve. Check if there are no air leaks in
the fuel supply line, and check if the lift of the fuel is
less than 3 ft. (1 meter). Check if there is no air in the
water fuel separator.
9 Check if the air intake in the canopy is not blocked.
10 Check the oil level and colour of the oil. Check the
coolant level

13 Check when the generating set is running, the delay
of 5 to 10 seconds in the power source selector
transfer.
14 Check voltage and frequency under ‘no load’
conditions.

conditions.
16 Check if the battery charger of the generating set is
working (max. 14.5 Volt).
