Pump with internal
pressure transducer
only
Internal pressure transducer is factory set to
close at psi (240 bar). Internal
transducer can be adjusted from
to psi (96 to 317 bar)
using key pad on pump. Adjustment is in
psi (, bar) increments. Internal
pressure transducer is set to open at
psi (62 bar) below point where it closed.
After pump starts lubrication cycle, motor
stops when pressure at pump reaches preset
pressure. Pump will go through two holding
periods, H and H. The following will use
factory setting of psi (240 bar) and
opening pressure of psi (179 bar).
Holding time (H1)
• Internal pressure transducer must reach
psi (240 bar) and stay above
psi (179 bar) for consecutive
seconds before going to H. If internal
pressure transducer drops below
psi (179 bar) during seconds,
pump will restart and run until internal
pressure transducer reaches
psi (240 bar).
Holding time (H2) – will last
for 30 seconds
• At the end of seconds, if internal
pressure transducer is above psi
(179 bar), pump will begin a vent cycle.
• If at the end of the seconds internal
pressure transducer is below
psi (179 bar), pump will restart and
run until internal pressure transducer
reaches psi (240 bar). When this
happens vent cycle will take place.
• If at the end of seconds the internal
pressure transducer is above
psi (179 bar), but during the H hold
time internal pressure transducer dropped
below psi (179 bar), pump will
restart and pump for seconds before
vent cycle begins.
Possible faults
• E Fault – a failure to build pressure at
pump within allotted minutes of
pumping time.
• E Fault – a failure to vent at pump.
Internal pressure switch has
seconds to open when motor reverses
to locate vent position.
• E Fault – a failure to vent at pump.
If at the end of the pause time pressure of
internal pressure transducer has not
dropped below psi (62 bar), an E
fault will occur.
Pump with internal
and external
pressure transducer
Internal pressure transducer is factory set to
close at psi (240 bar).
Internal transducer can be adjusted from
to psi (96 to 317 bar) using key
pad on controller. Adjustment is in
psi (6,9 bar) increments. Internal press-
ure transducer is set to open at
psi (62 bar) below point where it closed.
External pressure transducer is set to
close at psi (172 bar). Opening point of
external pressure transducer is adjustable
from to psi (14 to 69 bar).
It is factory set to open at psi (62 bar).
After pump starts a lubrication cycle,
motor will stop when pressure at pump
reaches preset pressure of
psi (240 bar). Pump can go through
three holding periods, H, H and H.
The following will use factory settings for
P and P.
Holding time (H1)
• Internal pressure transducer must reach
psi (240 bar) and stay above
psi (179 bar) for consecutive
seconds before going to H. If internal
pressure transducer drops below
psi (179 bar) during seconds,
pump will restart and run until internal
pressure transducer reaches
psi (240 bar).
Holding time (H2) – will last
for 30 seconds
• At the end of H, if internal pressure
transducer is above psi (179 bar)
and external pressure transducer has
reached psi (172 bar), pump will
begin vent cycle.
• At the end of H, if internal pressure
transducer is below psi (179 bar), or
both internal pressure transducer is below
psi (179 bar) and external pressure
transducer has not reached
psi (172 bar), an H will appear on
display. Pump will turn on again and pump
until internal pressure transducer has
reached psi (240 bar).
When internal pressure transducer is
above psi (179 bar) and external
pressure transducer has reached
psi (172 bar), vent cycle will
take place.
• If at the end of H internal pressure
transducer is above psi (179 bar)
but external pressure transducer has not
reached psi (172 bar), pump will
turn on for seconds and then stop and
wait until external pressure transducer
reaches psi (172 bar). H will appear
on display. When internal pressure trans-
ducer is above psi (179 bar) and
external pressure transducer has reached
psi (172 bar) vent cycle will
take place.
Holding time (H3)
• Holding time H will remain until
internal pressure transducer is above
psi (179 bar) and external pressure
transducer has reached
psi (172 bar), and then vent cycle
will take place. If both pressure transducers
do not reach preset settings within
allotted pumping time of minutes, an
alarm will occur. If internal pressure
transducer drops below psi
(179 bar) during H it will repump until
internal pressure transducer reaches
psi (240 bar).
Possible faults
• E Fault – a failure to build pressure at
pump within allotted minutes of
pumping time.
