SECTION A: GENERAL INFORMATION
A-1) RECEIVING:
Upon receiving the Control Panel, it should be inspected for
damage or shortages. If damage has occurred, file a claim
immediately with the company that delivered the basin
package.
A-2) STORAGE:
For best results, control panels should be stored in a
temperature controlled area that provides protection from the
elements and humidity.
A-3) SERVICE CENTERS:
For the location of the nearest Barnes® Pumps Service Center,
check your catalog, your Barnes Pumps, Inc. representative or
Barnes Pumps, Inc. Service Department in Piqua, Ohio,
telephone (937) 778-8947.
A-4) LOCATION:
Any alterations from the standard must be in accordance with
local codes. These control panels are not to be installed in
locations that would be classified as a HAZARDOUS location
in accordance with NEC ANSI/NFPA 70.
SECTION B - PRODUCT OVERVIEW
The UGP & UCP Series Panels were developed to support the
Barnes UltraGRIND low pressure sewer grinder packages.
The electrical hardware has been designed to function with the
Barnes SGV & SGPC Series Grinder Pumps. A detailed wiring
diagram is enclosed in each control panel, and should be
referred to during installation and package start-up.
B-1) GENERAL COMPONENTS DESCRIPTION:
The control panel is the brain of the pressure sewer basin
package. It receives water level or pump temperature signals
through the wiring from the basin package system. The panel
will turn the pump "ON" or "OFF" depending on the signals
received. A typical control wiring diagram can be seen on
pages 13, 14, 15 & 18, 19 20. The following are descriptions
of each component and their operation.
Circuit Breaker (CB) - The circuit breaker serves two
purposes. First it is a main disconnect for the simplex UGP and
UCP panels and pump power disconnect for duplex panels.
When servicing the pump or control panel, this circuit breaker
should be turned off and fuses pulled (duplex only). For stations
with panels mounted in the cover, this DOES NOT disconnect
the incoming power passing through the alarm box. The
second function of the circuit breaker is protection against short
circuit conditions. The circuit breaker will open or break a power
circuit under a catastrophic failure such as a motor winding or
cable short. The purpose of this action is to prevent fire and
wire damage.
Motor Start Contactor (MS) - The motor starter is a device
made up of two main components; the motor contacts and
electromagnetic coil. When the coil is energized by a 120 volt
control voltage, the armature closes the "double break" starter
contacts applying 115 or 230 volt power to the motor depending
on pump voltage. Terminal "T1" & "T2" are the pump
connection points for the SGPC pumps.
Control Circuit Fuses (FU1, FU2) - These fuses offer
overload protection to the control and alarm circuits. They are
down stream of the breaker (simplex). These fuses are sized
to protect the control circuit from a short and connected directly
to incoming power on duplex.
Overload (OL) (UGP Panels Only) - The overload relay is
installed attached to the motor starter. The purpose of the
overload relay is to protect the motor and turn it off when an
overload condition is sensed. The overload relay has three
"heaters" inside along with control contacts for use in the
control. When the operating current of the motor exceeds the
current set on the overload relay, the normally closed contact
in the control circuit will open and stop the motor. The overload
relay will need to be manually reset if it has been tripped due
to an overload situation.
Start & Run Capacitor (SC, RC) (UGP Panels Only) - On
single phase pumps, a capacitor is placed in series with the
start windings and in series with the run windings. These are
commonly referred to as the start and run capacitors. The start
capacitor improves the starting torque of the pump. The run
capacitor is designed to improve the motor efficiency during
operation.
Start Relay (SR) (UGP Panels Only)- The start relay is
installed in conjunction with the start and run capacitors on a
single phase motor. This device allows the motor to start and
accelerate up to speed under a load. When the motor contactor
is initially closed, the start capacitor boosts voltage to the
motor. The start relay monitors this voltage and disconnects
the start capacitor when the voltage reaches the designed
value, corresponding to a desired motor speed. The run
capacitor remains attached to the start winding at all times.
Alarm Light - A red indicator light located on the top of wall
mounted panels, or on the alarm box for panels located in the
cover. It is designed to be turned on when the fluid level in the
basin is above the normal pump "ON" point. When the Alarm
Light is lit, it either indicates a severe inflow of fluid, or a failure
of the pump to turn on. Service of the basin in a timely manner
will generally be required.
Audible Alarm Horn - An option on the UGP and UCP series
panels is to have an Audible Alarm Horn sound when the Alarm
Light is activated. The audible alarm can then be manually
silenced by pressing the silence button on the wall mounted
panels which de-energizes the alarm horn relay, or by turning
the manual On/Off switch located on the alarm box, to "Off" for
panels mounted in the cover. Remember to reset the Alarm
Horn once the problem has been corrected for units with the
manual switch.
