Electric Operated Centro-Matic Pump P653S
Pump with internal pressure transducer only:
The internal pressure transducer is factory set to close at 3500
psig (241 bar). The internal transducer can be adjusted from
1,400 psig to 4,600 psig (96 to 317 bar) using the key pad on
the pump. The adjustment is in 100 psig (6.9 bar) increments.
The internal pressure transducer is set to open at 900 psig (62
bar) below the point where it closed at.
After the pump starts a lubrication cycle, the motor stops when
pressure at pump reaches the preset pressure. The pump will
go through two holding periods, H1 and H2. The following will
use the factory setting of 3500 psig (241 bar) and the opening
pressure of 2600 psig (179 bar).
Holding Time (H1)
• Internal pressure transducer must reach 3500 psig and
stay above 2600 psig (179 bar) for 15 consecutive sec-
onds before going to H2. If the internal pressure trans-
ducer drops below 2600 psig during the 15 seconds, the
pump will restart and run until internal pressure transducer
reaches 3500 psig (241 bar).
Holding Time (H2) - Will last for 30 seconds
• At the end of 30 seconds, if the internal pressure trans-
ducer is above 2600 psig. (179 bar) the pump will begin a
vent cycle.
• If at the end of the 30 seconds the internal pressure trans-
ducer is below 2600 psig (179 bar), the pump will restart
and run until the internal pressure transducer reaches
3500 psig (241 bar). When this happens a vent cycle will
take place.
• If at the end of 30 seconds the internal pressure trans-
ducer is above 2600 psig (179 bar), but during the H1
hold time the internal pressure transducer dropped below
2600 psi (179 bar), the pump will restart and pump for 2
seconds before a vent cycle begins.
Possible Faults
• E1 Fault – A failure to build pressure at the pump within
the allotted 12 minutes of pumping time.
• E3 Fault – A failure to vent at the pump. The internal
pressure switch has 10 seconds to open when the motor
reverses to locate the vent position.
• E3 Fault – A failure to vent at the pump. If at the end of
the pause time the pressure of the internal pressure trans-
ducer has not dropped below 900 psig (62 bar) an E3 fault
will occur.
Pump with internal and external pressure transducer:
The internal pressure transducer is factory set to close at 3500
psig (240 bar). The internal transducer can be adjusted from
1,400 psig to 4,600 psig (96 to 317 bar) using the key pad on
the controller. The adjustment is in 100 psig (6.9 bar) incre-
ments. The internal pressure transducer is set to open at 900
psig (62 bar) below the point where it closed at.
The external pressure transducer is set to close at 2500 psig
(172 bar). The opening point of the external pressure trans-
ducer is adjustable from 200 psig to 1000 psig (14 to 69 bar). It
is factory set to open at 900 psig.
After the pump starts a lubrication cycle, the motor stops when
pressure at the pump reaches preset pressure of 3,500 psig
(240 bar). The pump can go through three holding periods,
H1, H2 and H3.
The following will use the factory settings for P7 and P8.
Holding Time (H1)
• Internal pressure transducer must reach 3500 psig and
stay above 2600 psig for 15 consecutive seconds before
going to H2. If the internal pressure transducer drops be-
low 2600 psig during the 15 seconds, the pump will restart
and run until the internal pressure transducer reaches
3500 psig.
Holding Time (H2) - Will last for 30 seconds
• At the end of H2, if the internal pressure transducer is
above 2600 psig and the external pressure transducer
has reached 2500 psig, the pump will begin a vent cycle.
• At the end of H2, if the internal pressure transducer is be-
low 2600 psig, or both the internal pressure transducer is
below 2600 psig and the external pressure transducer has
not reached 2500 psig, an H3 will appear on the display.
The pump will turn on again and pump until the internal
pressure transducer has reached 3500 psig. When the
internal pressure transducer is above 2600 psig and ex-
ternal pressure transducer has reached 2500 psig, a vent
cycle will take place.
• If at the end of H2 the internal pressure transducer is
above 2600 psi but the external pressure transducer has
not reached 2500 psig, the pump will turn on for 2 sec-
onds and then stop and wait until the external pressure
transducer reaches 2500 psig. An H3 will appear on the
display. When the internal pressure transducer is above
2600 psig and external pressure transducer has reached
2500 psig a vent cycle will take place.
Holding Time (H3)
• Holding time H3 will remain until the internal pressure
transducer is above 2600 psig and the external pressure
transducer has reached 2500 psig, and then a vent cycle
will take place. If both pressure transducers do not reach
their preset settings within the allotted pumping time of 12
minutes an alarm will occur. If the internal pressure trans-
ducer drops below 2600 psig during H3 it will repump until
the internal pressure transducer reaches 3500 psig.
