asssit_amps_limit: <WHOLE NUMBER ( 0 500** )> While assisting the charging of the Primary Battery, the DC-DC converter will limit the amount of power transferred between batteries to the maximum of its capability, or assist_amps_limit . This current limit is typically measured on the 2 nd battery side of the DC-DC converter, unless noted above below in the Supported DC-DC converter table. A value of 0 (default) will cause the DC-DC converter to run at its maximum capability. Set this to match the DCDC converter installation wiring as well as limits to the 2 nd battery alternator capability in the case of Charge Assist mode <WHOLE NUMBER ( 0 500** )> While augmenting the 2 nd battery with energy from the primary battery, theDC-DC converter will limit the amount of power transferred between batteries to the maximum of its capability, or AUG_amps_limit . This current limit is typically measured on the 2 nd battery side of the DC-DC converter, unless noted above below in the Supported DC-DC AUG_amps_limit: converter table. A value of 0 (default) will cause the DC-DC converter to run at its maximum capability. Set this to match the DCDC converter installation wiring as well as the maximum discharge limit of the primary in the case of 2nd Battery Augmentation mode ** Note: All the DC-DC related limits will be validated against the selected Device Type. If a value outside the allowed range of the devi ce has been specified (Mis and/or max), a ‘Miss - configured’ fault will be issued as there is something wrong with the system design. Make sure to validate all these limit values against the specific device specification sheets. AUG_LimitV: <FLOATING POINT NUMBER ( 0.0 20.0 )> Discharge limit for the Primary battery, If the Primary battery voltage drops below this value, 2 nd battery augmentation mode is disabled. Setting AUG_limitV provides for protection of over-discharging the primary battery. NOTE: The value here is normalized to the 12v/500Ah battery concept in line with all other CPE values. In this way the system will automatically adjust for a 24v or 48v install without needing to modify this value. Set = 0.0 (default) to disable this check
AUG_LimitSOC: <WHOLE NUMBER ( 0 100 )> Discharge limit for the Primary battery, If the SOC reported by an externally CAN connected BMS reports the SOC (State of Charge) of the Primary battery falls below this limit , 2 nd battery augmentation mode is disabled.
When supporting a DCDC converter, there are additional capabilities of the WS500 which may be utilized. Example, consider also the application of ‘Required Sensors’ (ref $SCA: command), and specifically the requirement of a CAN connected BMS/RBM. By setting Required Sensors, one will be able to disable the DC- DC converter when there is no CAN connected battery present. An example might be in a case where the
