Description of Operation
The lift time-out protects the lift pump and motor as-
sembly, eliminating the need for a height limit switch.
Lift is disabled after the pump runs for a programmed
amount of time. Lift is disabled on the MSW020/025-E
and MSW025/030-F trucks after operating continu-
ously for approximately 45 seconds. Lift is disabled on
the MPB040/045/050-E trucks after operating continu-
ously for approximately six seconds. The lift time-out
feature is reset once lower is selected.
The standard MSW020-E, MSW025-F, and MPB040-
E trucks are equipped with a battery pack consisting
of 4, 6 volt, deep cycle, automotive style batteries and
an onboard 25-amp charger. The battery pack uses a
4
175-amp, X-type connector. This connector provides
two auxiliary contacts for the truck inhibit circuit, al-
lowing the batteries to remain connected to the truck
while the charger is operating. The MSW020-E,
MSW025-F, and MPB040-E can be configured with a
standard 175-amp battery connector to accept the op-
tional GNB PalletPro.
The MSW025-E, MSW030-F, and MPW045/050-E
are shipped without batteries. Standard trucks have a
175-amp battery connector and will accept industrial
flooded cell batteries or maintenance free batteries,
such as the GNB PalletPro.
