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 4
smaller liquid-tight strain relieves 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.
