PowerSmoke 740 (HV) Operating Instructions
Version 2.0
1.1. Differences to PowerSmoke 600 / XL
The new smoke pumps
PowerSmoke 740
and
PowerSmoke 740 HV
replace the older PowerSmoke 600 / PowerSmoke XL.
Electronics are completely redesigned and even smaller and more
space saving. Control of the pump motor is improved and the software
supplemented by reasonable features. The motor turns for the fraction
of a second full speed during power on to generate a better starting
torque.
A stronger motor is built into the new
PowerSmoke
pumps which
allows for more flow rate. It can be directly powered by 2S Lipo
batteries without problems. The
PowerSmoke 740 HV
can be powered
by 3S LiPo batteries because this pump has a wider suction hose
connector. The
PowerSmoke 740
can only be supplied by up to 2S
LiPo batteries. At higher voltages this pump tends to cavitate.
The
PowerSmoke 740 HV
has a self purging passive check valve. The
cutoff valve and the self purging valve are integrated smartly into the
pump head. By using this valve it is assured, that the pump is
absolutely leak proof and that no smoke oil can pass when
disadvantageously mounted underneath the tank level. Furthermore,
exact on and off of the smoke is possible. Longer or permanent
smoking with a powered off pump is inhibited by usage of this passive
valve.
Of course, both pumps allow for usage of an electronically lock valve,
i.e. both pumps have a switching output, which controls an external
valve.
Hint:
During long pauses (> 1 day) the smoke oil tank should be drained completely.
