Pump with internal
pressure transducer
only
Internal pressure transducer is factory set to
close at 3 500 psi (240 bar). Internal
transducer can be adjusted from
1 400 to 4 600 psi (96 to 317 bar)
using key pad on pump. Adjustment is in
100 psi (6,9 bar) increments. Internal
pressure transducer is set to open at
900 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, H1 and H2. The following will use
factory setting of 3 500 psi (240 bar) and
opening pressure of 2 600 psi (179 bar).
Holding time (H1)
• Internal pressure transducer must reach
3 500 psi (240 bar) and stay above
2 600 psi (179 bar) for 15 consecutive
seconds before going to H2. If internal
pressure transducer drops below
2 600 psi (179 bar) during 15 seconds,
pump will restart and run until internal
pressure transducer reaches
3 500 psi (240 bar).
Holding time (H2) – will last
for 30 seconds
• At the end of 30 seconds, if internal
pressure transducer is above 2 600 psi
(179 bar), pump will begin a vent cycle.
• If at the end of the 30 seconds internal
pressure transducer is below
2 600 psi (179 bar), pump will restart and
run until internal pressure transducer
reaches 3 500 psi (240 bar). When this
happens vent cycle will take place.
• If at the end of 30 seconds the internal
pressure transducer is above
2 600 psi (179 bar), but during the H1 hold
time internal pressure transducer dropped
below 2 600 psi (179 bar), pump will
restart and pump for 2 seconds before
vent cycle begins.
Possible faults
• E1 Fault – a failure to build pressure at
pump within allotted 12 minutes of
pumping time.
• E2 Fault – a failure to vent at pump.
Internal pressure switch has
10 seconds to open when motor reverses
to locate vent position.
• E3 Fault – a failure to vent at pump.
If at the end of the pause time pressure of
internal pressure transducer has not
dropped below 900 psi (62 bar), an E3
fault will occur.
Pump with internal
and external
pressure transducer
Internal pressure transducer is factory set to
close at 3 500 psi (240 bar).
Internal transducer can be adjusted from
1 400 to 4 600 psi (96 to 317 bar) using key
pad on controller. Adjustment is in
100 psi (6,9 bar) increments. Internal press-
ure transducer is set to open at
900 psi (62 bar) below point where it closed.
External pressure transducer is set to
close at 2 500 psi (172 bar). Opening point of
external pressure transducer is adjustable
from 200 to 1000 psi (14 to 69 bar).
It is factory set to open at 900 psi (62 bar).
After pump starts a lubrication cycle,
motor will stop when pressure at pump
reaches preset pressure of
3 500 psi (240 bar). Pump can go through
three holding periods, H1, H2 and H3.
The following will use factory settings for
P7 and P8.
Holding time (H1)
• Internal pressure transducer must reach
3 500 psi (240 bar) and stay above
2 600 psi (179 bar) for 15 consecutive
seconds before going to H2. If internal
pressure transducer drops below
2 600 psi (179 bar) during 15 seconds,
pump will restart and run until internal
pressure transducer reaches
3 500 psi (240 bar).

Holding time (H2) – will last
for 30 seconds
• At the end of H2, if internal pressure
transducer is above 2 600 psi (179 bar)
and external pressure transducer has
reached 2 500 psi (172 bar), pump will
begin vent cycle.
• At the end of H2, if internal pressure
transducer is below 2 600 psi (179 bar), or
both internal pressure transducer is below
2 600 psi (179 bar) and external pressure
transducer has not reached
2 500 psi (172 bar), an H3 will appear on
display. Pump will turn on again and pump
until internal pressure transducer has
reached 3 500 psi (240 bar).
When internal pressure transducer is
above 2 600 psi (179 bar) and external
pressure transducer has reached
2 500 psi (172 bar), vent cycle will
take place.
• If at the end of H2 internal pressure
transducer is above 2 600 psi (179 bar)
but external pressure transducer has not
reached 2 500 psi (172 bar), pump will
turn on for 2 seconds and then stop and
wait until external pressure transducer
reaches 2 500 psi (172 bar). H3 will appear
on display. When internal pressure trans-
ducer is above 2 600 psi (179 bar) and
external pressure transducer has reached
2 500 psi (172 bar) vent cycle will
take place.
Holding time (H3)
• Holding time H3 will remain until
internal pressure transducer is above 2
600 psi (179 bar) and external pressure
transducer has reached
2 500 psi (172 bar), and then vent cycle
will take place. If both pressure transducers
do not reach preset settings within
allotted pumping time of 12 minutes, an
alarm will occur. If internal pressure
transducer drops below 2 600 psi
(179 bar) during H3 it will repump until
internal pressure transducer reaches
3 500 psi (240 bar).
Possible faults
• E1 Fault – a failure to build pressure at
pump within allotted 12 minutes of
pumping time.
