Pump Start-Up:
Refer to pump Installation and
Service Manual.
WARNING: Before handling
these pumps and controls,
always
dis con nect
the
power first. Do not smoke or
use sparkable electrical devices
or flames in a septic (gaseous) or
possible septic sump.
The maintenance schedule
will vary with operating and
environmental con di tions. It will
also vary with the specific type of
control supplied. The list herein is
a guide only.
1.
Exercise breaker through
one cy cle. Be careful not to
overexercise as the break
er
is not a switch ing device.
Excessive operations tend
to affect the trip curve of
the breaker.
2. Check contactors and relays
for excessive humming. This
can be accomplished by
turning pumps on and off
in the Hand mode with the
H-O-A switch.
3. Check pump run light(s) by
run
ning pump(s) in Hand
mode. Check bulb(s) in any
other light(s).
4. With the power off, check
con ti nu ity of all control fuses.
5. Check voltage at primary
and sec
ond
ary of control
transformer.
6.
Check the pump full
load amps.
7. For 1 phase panels with start
circuit, about 5 seconds after
the pump starts check the
Black, and Red pow
er
wires are con nect ed to pan el
correct ly.
3. WARNING! Live voltage can
kill! Check incoming power
volt age to make sure that
it is correct for panel and
pump model.
4. Energize control panel. (Turn
on power to panel.)
5. Check overload relay and
verify reset mode (if overload
is sup plied).
6. WARNING! Live voltage
can kill! Check voltage to the
panel and at secondary of
control trans form er using a
voltmeter. If no transformer is
supplied, check volt age at the
circuit breakers.
7. With H-O-A switch in hand,
check dis charge to ver i fy the
pump is run ning. Check for
flow. On three phase power,
check to see if each pump
has prop er ro ta tion. Wrong
ro ta tion will give low flow.
8.
Check full load current
with amp probe and compare
it with the name plate rat ing.
On three phase pumps, check
all three phases. On single
phase pumps, check black
pump lead.
9. Check operation of start relay,
if supplied on single phase
panels, per procedure in Item
#7 of Maintenance Instructions.
10. With H-O-A switch in Auto,
check float op er a tion and
response to control panel to
the float operation. For
sequence of op er a tion, refer to
design specification.
11. Make sure H-O-A switch is left
in the Auto position after
start-up is completed.
voltage from terminal 1 to
terminal 2 on the start relay
to be sure that the relay has
operated. The voltage from
terminal 1 to terminal 2 on
the start relay must exceed
10 VAC. For some pumps
the voltage may exceed 400
VAC. If after 5 seconds the
voltage from terminal 1 to
terminal 2 on the start relay
does not exceed 10 VAC, stop
the pump as the start capacitor
may be damaged in about 15
seconds.
If the start relay is not
operating, check the pump and
the system voltage to be sure
that they match. Check the
power wiring to ensure that the
pump is connected properly.
Start the pump once more and
check that the voltage from
the terminal for the black wire
to the white wire is within
system tolerance. Call for
help if you cannot resolve the
problem.
8. Check junction boxes for
moisture. Moisture may
cause chattering of relays
and contactors.
9. Check for moisture inside
control panel enclosure.
Moisture can cause damage to
electrical com ponents. Check
door gasket for prop er seal.
10. Check labels to verify they
have not been damaged.
11. Lubricate enclosure hinges.
12. Pull floats and check for
proper operation and ensure
there is no foreign buildup
on them.
