How to limit the total load bank capacity on SIGMA LT load banks?
During certain testing it may be desirable to limit the capacity of a given load bank. This is done at start up. When the load bank is first powered up, the Model, Load Limit (kW), and software version are displayed.
To limit the load bank capacity according to the figure above, depress and hold the corresponding load step button when power is applied. This will limit the kW to 25%, 50%, 75%, or 100%.
Note: limiting the capacity is retentive, and if a different capacity is required, it must be set the same way during a control power on condition.
