4.2.2 Relay settings
Remark: thresholds are disabled when set at 0
_______________________________________________________________
11. Relay mode
DFLT Default mode. The relay thresholds Nos. 16 up to 31 can be used to control the relay.
CHRG Charger mode. The relay will close when the state-of-charge falls below setting 16
(discharge floor) or when the battery voltage falls below setting 18 (low voltage relay).
The relay will be open when the state-of-charge is higher than setting 17 (clear state-of-
charge relay) and the battery voltage is higher than setting 19 (clear low voltage relay).
Application example: start and stop control of a generator, together with settings 14 and 15.
REM Remote control of the relay. In this mode the relay can be controlled by another device,
for example the Color Control GX.
_______________________________________________________________
12. Invert relay
This function enables selection between a normally de-energized (contact open) or a
normally energized (contact closed) relay. When inverted, the open and closed conditions
as described in setting 11 (DFLT and CHRG), and settings 14 up to 31 are inverted.
The normally energized setting will slightly increase supply current in the normal operating mode.
Default
OFF: Normally de-energized
_______________________________________________________________
13. Relay state (read only)
Displays whether the relay is open or closed (de-energized or energized).
_______________________________________________________________
14. Relay minimum closed time
Sets the minimum amount of time that the CLOSED condition will remain present after the
relay has been energized.
Application example: set a minimum generator run time (relay in CHRG mode).
15. Relay-off delay
Sets the amount of time the 'de-energize relay' condition must be present before the relay
opens.
Application example: keep a generator running for a while to better charge the battery (relay in CHRG
mode).
Default
0 minutes
_______________________________________________________________
16. SOC relay
(Discharge floor)
When the state-of-charge percentage has fallen below this value, the relay will close.
The time-to-go displayed is the time to reach the discharge floor.
