Lines 1-2 and 5-6 above sets the right polarity for the reversible pump. Lines 3 and 7 powers the pump.
Lines 4 and 8 turns the pump off.
After the activation (all conditions are met), the rule becomes inactive until conditions will no longer
match. Imagine that tank 1 has 10% level and the Tank Adapter runs the pump in the Example 5. When
the level reached 15%, the user turned off channel 3 on the YDCC unit manually (from connected buttons
or from the MFD screen) and turned off the pump. In this case, the rule on line 3 will not try to run the
pump again, despite the level still being less than 20%, because it was already activated. It will be activated
again only when the level goes to 20.1% or more, for a at least half of second (with the respect of DAMPING
setting, see Section VI.2.4).
Example 6.
Turns on digital switching channel 3 on bank 0 if the level in the tank connected to channel A
is less than 20% for at least 10 seconds. After 5 minutes (300 seconds plus 10 seconds for activation of the
first rule), try to turn on the channel again if the level is still less than 20%.
YD:SWA2 ON <20 10 0 3
YD:SWA3 ON <20 310 0 3
In the example above, the second rule will be activated 5 minutes later, and if the user turned off the
channel manually, the second rule will turn the channel on again.
In real conditions, ballast tank management system must take in account the heeling and actual level in
tanks (corrected to heeling) to drain or fill the system, or to pump the water between tanks, etc. This cannot
be done with the simple rules of the Tank Adapter, but can be programmed with the
