Inspection Points
Inspection Points – Control Panels
The system may have multiple control panels. Identify if there are control
panels on the section of the system that you are about to start-up.
If the tank or basin has associated controls, perform the following start-up
steps:
1.
Panel documentation:
Locate the panel-wiring diagram inside
the panel and verify the document matches the document number
found on the inside of the front panel door. If you can’t find the wiring
diagram, contact Orenco at (800) 348-9843 or (541) 459-4449 to
have a copy e-mailed or faxed to you.
2.
Wiring installation:
Verify all of the main
breakers are in the
“OFF” position. Inspect
the wire terminations
in the panel by giving
a light tug to all of the
float wires, pump wires,
pump power lines, and
main power lines in the
panel. If a wire comes
loose, reattach the wire
correctly.
WARNING:
Failure to identify a loose wire may cause
intermittent failures, inconsistent panel operation and over-
current conditions on the pumps.
3.
Conduit seal installation:
Check for conduit seals on all conduit
connections to the control panel.
WARNING:
Failing to seal the conduit may allow corrosive gasses
to corrode major components. Orenco recommends conduit seals
for all connections to the control panel to assure proper system
operation and component longevity.

. Power supply voltage:
Make sure the panel breakers are switched
off, and check the power supply voltage at the panel.
• On 120 V panels, measure voltage between L1 and ground. The
voltage should be within ten percent of nominal.
• On 230 V panels, measure the voltage between L1 and ground,
and between L2 and ground. The voltage of each leg should be
approximately 115 volts. Measure the voltage between L1 and L2.
The voltage should be within ten percent of nominal.
• On 208 V, 230 V, and 460 V 3-phase panels, measure the voltage
between L1 & L2, L2 & L3, and L3 & L1. The voltage between
each leg should be 208, 230 or 460 volts, respectively. If there
is a voltage difference between line legs, it is an indication that
the power source may be undersized. The voltage between each
leg and ground on 208 volts should be approximately 120 volts.
The voltage between each leg and ground on 460 volts should be
approximately 277 volts. (Due to the variability in the ways 230 V,
3-phase power can be wired, there is not a standard test method.)
5.
Neutral and ground voltage:
Check for any voltage difference
between each neutral (N) wire in the panel and ground. If there is
a difference in voltage, use the wiring diagram to track down the
source of the difference and correct it.
6.
Controls circuit:
Connect the controls circuit if it is not already
connected. The controls circuit is now ready to be turned on. Do not
turn on the pump circuit at this time.
WARNING:
Turning the pump circuit on at this time can damage the
panel or the pump if the pumps and floats are miswired or if there
isn’t sufficient liquid in the tank.
