Relay Contacts (rated at 60VDC or 42V AC, 0.5A)
From the factory, the Cordex controller is congured with the relay assignments shown below. The relays can
be unassigned from their factory conguration and remapped. For example Relay 2, K2, can be unassigned
from LVD #2 then remapped as an alarm relay. Refer to the Cordex controller manual for details.

2.4 Low Voltage Battery Disconnect (Optional)
A built-in AMPS24 shutdown cuts off the load
during a lengthy power outage.
Installing an LVD (Alpha part number 020-
615-20), between the AMPS24 HP and the
batteries, disconnects the AMPS24 HP from
the batteries to prevent further drain of the
batteries during a lengthy power outage.
The controller is configured with a relay
assigned to LVD #1. Figure 5 shows how to
wire the normally closed contacts of the LVD
#1 relay to activate the LVD. The activation
value is set in the Controls >LVD C ontrol
menu—see the controller software manual.
