Illustration 3 g03603636The default menu will display the engine rpm, the gear, the machine speed, and payload estimator (if equipped).
Payload Estimator (If Equipped) - Payload estimator is used to estimate the weight of material in the scraper bowl during a haul segment. The weight estimate will be recorded at the conclusion of the haul segment. If the cutting edge contacts the ground, or is in the fully raised position during the haul segment, the weight estimate will not be valid. Maximum payload estimate accuracy is achieved when using Sequence Assist. If the sequence assist cycle is not followed, payload estimator accuracy may be reduced. The cumulative payload is displayed in the default menu as well as the trip totals menu. The cumulative payload and load counter may be reset in the trip totals menu. The lifetime total payload weight is shown in the lifetime totals menu.If the cutting edge contacts the ground, or is in the fully raised position during the haul segment, the weight estimate will not be valid. Maximum payload estimate accuracy is achieved when using Sequence Assist. If the sequence assist cycle is not followed, payload estimator accuracy may be reduced.Recommended practices include:
Run standard cut-haul-fill-return work cycles, using Sequence Assist to switch between each segment of the work cycle.Note: Sequence Assist usage is not required, but operating with it will result in more accurate payload estimates.
Dig for at least 20 seconds, with the ejector fully retracted and apron open normally.
Haul loaded for at least 30 seconds before dumping.
Haul with the apron closed and in float and with the bowl carried clear of the ground and not against the top cylinder stops.
Do not make large bowl movements or turn apron float off and on during the haul.
Do not move the ejector other than while
