Safety Guidelines

1. DO NOT USE WITH FLAMMABLE OR EXPLOSIVE FLUIDS SUCH AS GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT USE IN EXPLOSIVE ATMOSPHERES. CONTROL PANEL SHOULD ONLY BE USED IN WATER AND WASTEWATER APPLICATIONS THAT ARE NOT RATED AS A HAZARDOUS LOCATION.
2. DO NOT WORK ON THE CONTROL PANEL WITH LIVE VOLTAGE APPLIED TO THE CONTROL PANEL WITH WET HANDS OR WHEN STANDING ON A WET SURFACE.
3. DISCONNECT ALL ELECTRICAL SERVICE BEFORE WORKING OR HANDLING THE CONTROL PANEL.
4. INCOMING VOLTAGE MUST MATCH THE CONTROL PANEL VOLTAGE. REFER TO THE PANEL SCHEMATIC FOR COMPLETE INFORMATION.

Installation of the Control Panel:

1. Determine mounting location for the control panel. If splicing is required between the level switches and the panel, we recommend a junction box. CAUTION! Use conduit sealant and waterproof wire nuts for connections. Make sure all connections are water tight.
2. Determine conduit entrance locations on control panel and install per local codes. Check schematic and determine number of power sources required. Use conduit sealant on all conduits to prevent moisture and gases from entering control panel.
3. Connect control/alarm and pump power conductors to the proper terminals. The schematic and terminal blocks will be labeled for proper connection.
4. Verify correct panel operation after installation of panel, power and level switches are complete.

Installing the Starter Packs

1. A Starter Pack (Fig. A) comes pre assembled with the start capacitor (1) run capacitor (2) and start relay (3) mounted on a plug and play bracket.
2. Use the empty space on the right side of the control panel to mount BOTH Starter Packs. (Fig. 1) To secure the Starter Packs to the control panel, place (Fig. 3) on top of (Fig. 2) by setting the bracket on top of the screws (Fig. 4), then slide the bracket down so the screws are in the narrow part of the mounting holes (Fig. 5), then tighten the screws.
3. After securing the Starter Packs inside of the control panel (Fig. 6) you will connect the wires from BOTH Starter Packs to the top of the corresponding terminal blocks (Fig. 7). W=White, B=Black, R=Red

Connecting the Pumps, Thermal Wires:

Your pump has 5 colored wires. White, Black, Red, Blue and Orange
Pump Connections: The White, Black and Red wires from each pump connect to the corresponding terminal blocks labeled Pump 1 Connection and Pump 2 Connection.W=White, B=Black, R=Red
Pump 1 & 2 Thermal Sensors: The remaining two wires from each pump will be Blue and Orange. They are connected to the corresponding terminal blocks labeled Pump 1 Thermal Sensor and Pump 2 Thermal Sensor . BL=Blue, OR=Orange
Testing the Thermal Sensor:

1. Put one ohm meter probe on the Blue wire and one on the Orange wire.
2. If the reading is 0 or near 0 the thermal sensor is good.
   If the reading is OL the pump has been or currently is overloaded.

Connecting Pump 1 & 2 Seal Fail Probes:
(Seal fail may not be an option on your pump)
Pump 1 Seal Probe: Use the terminal blocks labeled Pump 1 Seal Sensor
Black wire from probe to terminal 11. BK=Black
Yellow wire from probe to terminal 12. YW=Yellow

Pump 2 Seal Probe: Use the terminal blocks labeled Pump 2 Seal Sensor
Black wire from probe to terminal 15. BK=Black
Yellow wire from probe to terminal 16. YW=Yellow
Testing Seal Fail Probes:

1. Put one ohm meter probe on the Black wire of the sensor.
2. Place the other ohm meter probe on the “Hex” Nut portion of the sensor. The ohm meter should read “continuity” or close to zero ohms, If it reads “open” or “High” ohms then the sensor is defective.
3. Put one ohm meter probe on the seal probe.
4. Place the other ohm meter probe on the yellow wire. The ohm meter should read “continuity” or close to zero ohms, If it reads “open” or “High” ohms then the sensor is defective.

Setting Overload FLA to Pump FLA:

Use a Phillips head screwdriver to adjust the yellow dial to the full load amps (FLA) of EACH pump. I.e. If the FLA of your pump is 6.0 you would set the yellow dial on BOTH overload relays to 6.

Re-Setting Overloads:
To reset a tripped overload, push the blue RESET switch. Make sure the dial is in the ”H” position.

To verify the Overload has tripped.
Use an ohm meter to verify if an overload has tripped. Place one of the ohm meter probes on terminal 97 of the overload and place the other probe of the ohm meter on terminal 98 of the overload. If your reading is high the overload is not tripped. If your reading shows continuity or 0 ohms, the unit is tripped and should be reset.

Connecting Level Switches:
Float switches are most commonly used, but 1 Phase Duplex & Grinder Vortex series control panels can be used with any dry contact type level or pressure switch. Illustrations below show float switches installed for Pump Down applications. Refer to float switch instructions for mounting of pipe clamp or weighted floats.

Incoming Power Configurations:

Illustrations below show you how to connect power for the pump and the control circuits. Use two incoming power sources. (A) is the pump circuit and (B) is the alarm circuit.

Alarm Mode Configurations:

1 Phase Duplex Grinder & Vortex series control panels use two terminal blocks for alarm mode configurations. A 10 position main terminal block is for power and level switch connections. A separate 3 position terminal block is used for dry auxiliary contacts. A 5 amp, 120 VAC max load can be applied to the auxiliary terminals. The auxiliary contacts are Form C, Single Pole, Double Throw. (Common, Normally Open, Normally Closed).
Contacts change state when in alarm condition.

Circuit Board Command Center:

The control panel is equipped with a circuit board and control command center. There are two “HOA” switches, a pump selector switch and a System Test switch. Two green power “on” indicators provide visual indication for the control and alarm fuses. Fuses must be replaced with 1 amp fast acting 5 mm X 20 mm fuses. Four red level indicators are provided for level indication of the off/stop, lead, lag and alarm switches. On the bottom of the command center there are two green indicator lights for Pump 1 Run and Pump 2 Run.

HOA Switches:

Placing the HOA switch in “H” (hand mode) will activate the pump. In the “O” (off) mode the pump will not activate. Placing the switch in “A” (automatic) mode, will activate the pump with the level switches. Place the switch in “A” mode when installation is complete and normal operation is desired.

Pump Selector Switch:

Placing the switch in “ALT” will allow the panel to automatically alternate the pumps on successive cycles. If a pump needs to be taken out of service, place the switch to the pump that will remain in service. I.E. if pump 2 is out of service, place the switch to “P1” so the panel will activate pump 1 on each cycle.
Note: If the level reaches the lag/alarm or alarm switch level the alarm will activate. When a pump is selected with the pump selector switch only that pump will activate (simplex mode).
Note: Do not use the Pump Selector Switch as a permanent means of simplex a duplex system. If the intent of your system is not to provide alternation, but to have a second pump for emergency back up, call the factory for a panel designed for that application.

System Test Switch:

Use the “System Test” switch to verify panel operation and float status. To check panel operation place the pump selector switch to “Alt” and the HOA switches to “A”. Press and hold the “System Test” switch – one pump should activate. De-Press the “System Test” switch and Re-Press again and the other pump should activate. The panel will alternate the pumps each time the “System Test” switch is pressed. Use the “System Test” switch to verify float status. In normal operation the float status LED’s activate when the level switch “closes”. If the floats are activated out of sequence (I.E., “off” float is not activated but the “lead” float is activated) the LED for the “lead” switch will not illuminate. Use the “System Test” switch to determine exact status of each float. When the “System Test” switch is pressed and held, the circuit will automatically give true indication of which level switches are “closed” or “opened”. You can perform this test with the “HOA” switch in either the “O” (off) or “A” (auto) modes.

Description of Operation:

3 Float:
With both “HOA” switches in “Auto” and the pump selector switch in “ALT”: On water rise, the “off/stop” float will close and when the level closes the “lead” float, pump 1 will start and pump down to the “off/stop” float. The panel will alternate so on the next cycle pump 2 will activate. If the level reaches the “lag” float, both pumps and the alarm will activate and pump down to the “off/stop” float. The alarm turns off at the “off/stop” level.(See float configurations Fig A).

Mounting Level Switches:
Float switches are most commonly used, but the 1 Phase Duplex Grinder & Vortex control panel can be used with any dry contact type level or pressure switch. Refer to float switch instructions for mounting of pipe clamp or weighted floats. Illustrations show float switches installed for pump down applications.

4 Float:
With both “HOA” switches in “Auto” and the pump selector switch in “ALT”: On water rise, the “off/stop” float will close and when the level closes the “lead” float, pump 1 will start and pump down to the “off/stop” float. The panel will alternate so on the next cycle pump 2 will activate. If the level reaches the “lag” float, both pumps will activate and pump down to the “off/stop” float. If the water reaches the “alarm” float the alarm will activate. The alarm turns off at the “off/stop” level. (See float configurations Fig B).
