When the state of charge percentage has risen above the "clear relay" value, the relay will open (after a delay, depending on the
Relay minimum closed time
[32] and/or the Relay off delay [32] settings).
The "clear relay" value needs to be greater than the "set relay" value.
Setting Default Range Step size
Set relay value (setting 16) 50% 0 - 99% 1%
Clear relay value (setting 17) 90% 0 - 99% 1%
When the "set relay" and "clear relay" values are equal, the state of charge condition will be unable to drive
the relay
.
Note that this setting is also known as the discharge floor. The time-to-go reading displayed by the battery
monitor relates to this setting. The time to go is the time left until this setting (the discharge floor) has been
reached.
7.3.7. Low voltage relay
When the battery voltage falls below the "set relay" value for more than 10 seconds the relay will close.
When the battery voltage rises above the "clear relay" value, the relay will open (after a delay
, depending on the Relay minimum
closed time [32] and/or the Relay off delay [32] settings).
The "clear relay" value needs to be greater than the "set relay" value.
Setting Default Range Step size
Set relay value (setting 18) 0V 0 - 95V 0.1V
Clear relay value (setting 19) 0V 0 - 95V 0.1V
7.3.8. High voltage relay
When the battery voltage rises above the "set relay" value for more than 10 seconds the relay will close.
When the battery voltage falls below the "clear relay" value, the relay will open (after a delay
, depending on the Relay minimum
closed time [32] and/or the Relay off delay [32] settings).
The "clear relay" value needs to be greater than the "set relay" value.
Setting Default Range Step size
Set relay value (setting 20) 0V 0 - 95V 0.1V
Clear relay value (setting 21) 0V 0 - 95V 0.1V
7.3.9. Low starter voltage relay
This setting is available if the aux input has been set to "Starter battery", see the Aux input [40] setting.
When the auxiliary (e.g. starter battery) voltage falls below "set relay" value for more than 10 seconds, the relay will be closed.
When the auxiliary voltage rises above the "clear relay" value, the relay will open (after a delay
, depending on the Relay minimum
closed time [32] and/or the Relay off delay [32] settings).
The "clear relay" value needs to be greater than the "set relay" value.
Setting Default Range Step size
Set relay value (setting 20) 0V 0 - 95V 0.1V
Clear relay value (setting 21) 0V 0 - 95V 0.1V
7.3.10. High starter voltage relay
This setting is available if the aux input has been set to "Starter battery", see the Aux input
[40] setting.
When the auxiliary (e.g. starter battery) voltage rises above the "set relay" value for more than 10 seconds, the relay will be
closed.
When the auxiliary voltage falls below the "clear relay" value, the relay will open (after a delay, depending on the Relay minimum
closed time [32] and/or the Relay off delay [32] settings).
