SubDrive Duplex Alternator
9. The alarm contacts are an optional feature. The alarm contacts are a set
of dry contacts that close when the alternator declares a fault. These
contacts are rated for a maximum of 24 VAC at 1A (amps) or 24 VDC at
0.5A (amps). Any type of external alarm indicating load may be
attached to these dry contacts as long as the maximum voltage and
current criteria is not exceeded. If the alarm contacts are not used, use
the rubber pull-plug on the unused strain relief to seal the unit from the
weather. (See Figure 4 below).

10. When all the cables have been connected to the alternator, tighten the
four smaller liquid-tight strain reliefs around the cables to 25-30 in lbs.
and tighten the larger center strain relief to 55-60 in lbs to maximize
the unit's weather protection.

Start-Up and Operation

Apply power to the alternator controller and the SubDrive units. Only the timing
indicator light will be illuminated until the alternator detects the presence of the
SubDrive units. This will require letting the system come up to pressure. A steady
green light indicates which pump system is the primary system and that it has no
demand. A flashing green light indicates that a system has demand.
