Programming the Auxiliary Relay

The FLEXNet DC’s unpowered relay is rated 5 amps/30VDC.

NOTE: This relay is not fused and requires appropriate sized wiring and over-current protection. Damage due to unprotected relay devices is not covered by the warranty.

The relay may be configured in one of two modes:

1.AUTO activates the relay based on user selected battery voltage, percentage of SOC delay times and invert logic settings.

2.MANUAL allows direct relay control using the MATE, causing the relay to behave as a switch.

NOTE: When the MATE’s AGS function is active, it will override the AUX set points of whichever component it has been programmed to control (this should be the AUX connected to the generator). OutBack strongly recommends using the AGS function of the MATE to control a generator.

AUTO Mode

Six user adjustable set points govern the control logic of AUTO Mode: 1. Vbat Hi (0-99.9Vdc)

2. Vbat Lo (0-99.9Vdc)

3. %SOC Hi (0-100%)

4.%SOC Lo (0-100%)

5.Hi Delay Time in Minutes (0-240 minutes)

6.Lo Delay Time in Minutes (0-240 minutes)

If the battery voltage set points are not met, then the %SOC set points are evaluated.

If %SOC set points are not met, then no action is taken.

If either volts or %SOC set points are met, then the delay timer runs.

When the set points have been satisfied for a time (either Hi Delay for the Hi set points met or Lo Delay for the Lo set points met) the relay is actuated.

Please see pages 26-28 to set the AUX Mode.

Relay Logic:

Expressed as NO/NC (Normally Open/Normally Closed), basically off/on

May be controlled via the invert logic selection from the MATE.

Toggling the relay logic setting changes the logic mode for Hi or Lo set points

Example: The relay’s contacts are closed when the Hi set point is satisfied and open again when the Lo set point is achieved. However, you want the relay’s contacts to be open under this condition. Toggling the invert logic set point will accomplish this. The truth table appears as follows:

Invert Logic

Hi Set Point Satisfied

Lo Set Point Satisfied

Yes

Relay Open

Relay Closed

No

Relay Closed

Relay Open

The Hi and Lo delay times are set in minutes.
