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.

Connecting the Pump and Thermal Wires:
Your pump has 5 colored wires. White, Black, Red, Blue and Orange
Pump Connection: The White, Black and Red wires connect to the terminal block labeled Pump #1 Pump Connection. The pump leads are connected to T1, T2 and T3.
WARNING! After wiring a 3 phase control panel YOU MUST CHECK THE PHASE ROTATION. The wire leads may need to be reversed to match rotation. Refer to your pumps O&M manual for more information.
Pump 1 Thermal Sensor: The remaining two wires will be Blue and Orange. They are connected to the terminal block labeled Pump 1 Thermal Sensor. BL=Blue, OR=Orange The Blue wire is connected to #7 and the Orange wire is connected to #8.

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.

Pump 1 Seal Fail Probe: (Seal Fail may not be an option on your pump)
The Seal Probe wires are connected to terminals 9 and 10 which are labeled Pump 1 Seal Sensor. The Black wire from the Seal Probe is connected to terminal 9 which is labeled BK for Black. The Yellow wire from the Seal Probe is connected to terminal 10 which is labeled YW for Yellow.

Seal Probe from pump
Seal Fail may not be an option on your pump.

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 the MPS (Motor Protective Switch):
The MPS is used for pump short circuit and overload protection.

1. Use a screw driver to set the yellow dial on the MPS (Motor Protective Switch) to the FLA (Full Load Amps) of the pump. i.e. If your pumps FLA is 6.3 set the yellow dial to 6.3.
2. When the panel is ready for operation, place the switch in the on position by turning the switch clockwise to the 12 o’clock position.

Test the MPS (Motor Protective Switch):
To test the MPS:

1. Turn the switch to the “On” or 12 o’clock position.
2. Place a screw driver in the test slot.
3. The switch should snap to the “Off” or 9 o’clock position.

Re-Setting the MPS (Motor Protective Switch):
To Re-Set the MPS turn the switch back to the “On” or 12 o’clock position.

Mounting Level Switches:

Float switches are most commonly used, but 3 Phase Grinder & Vortex control panels can be used with any dry contact type level or pressure switch. The Illustration below shows float switches installed for Pump Down applications. Refer to float switch instructions for mounting of pipe clamp or weighted floats.

Field Wiring Connections:

3 Phase Simplex Grinder & Vortex control panels are multi voltage.

1. Set the transformer voltage to match incoming power voltage.

2. Connect the incoming power.

3. Setting the Transformer:

   1. Set the transformer voltage to match incoming power voltage. WARNING!

   Incoming power must be off when wiring the transformer.
   Remove the label from the (field installed) red wire after verifying which voltage terminal the wire is supposed to be connected to. The incoming voltage has to match the transformer voltage or DAMAGE WILL OCCUR.

4. Connect your incoming power to L1, L2 and L3

   2. Connecting the Incoming Power:![PENTAIR G2DT 43 Jung Pumpen Submersible

After wiring a 3 phase control panel YOU MUST CHECK THE PHASE ROTATION. The wire leads may need to be reversed to match rotation. Refer to your pumps O&M manual for more information.

Simplex Circuit Board Command Center

There is one HOA (Hand-Off-Auto) switch. This HOA switch is also used as the System Test switch for diagnosing the control panel.
Two green power “on” indicators provide visual indication for the control and alarm fuses. Fuses must be replaced with 1 amp fast acting 5mm X 20mm fuses
The Pump Run indicator light is green. If this light is illuminated the pump is running.
The Stop float, Start float and Alarm float indicator lights are red.

Circuit Board Terminal Blocks:
3 Phase Simplex Grinder & Vortex control panels use two terminal blocks for alarm mode configurations. An 8 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.

3 Phase Simplex – How to use the System Test switch
#1. Check the incoming power on the top of the command center.

If the indicator lights are illuminated the fuses are good.
If one or both of the indicators are not illuminated the fuse or fuses need to be replaced. If the fuse or fuses do not fix the problem the incoming power needs to be examined.

2. View the current status of your system. The indicator lights illuminate as

each float rises with the liquid level in the tank.

All three floats are not activated. Only the Control Power and Alarm Power indicator lights should be illuminated.

If the Stop float is activated the Stop light will illuminate.

The Stop float and the Start float are activated so the Stop float and the Start float indicator lights are illuminated.

All floats are up so all indicators are illuminated.

#3. Operating the pump manually with the HOA (Hand-Off-Auto)

**3 Phase Simplex – How to use the System Test switch

4. Using the System Test switch to troubleshoot your control panel.**

Place the HOA (Hand-Off-Auto) switch in the “Hand” position. The Pump Run indicator light will illuminate and turn on the pump.

Place the HOA (Hand-Off-Auto) switch in the “Hand” position and you will be automatically checking the true status of the floats. EXAMPLE: Fig #2. The green pump run light is illuminated because the HOA switch is in the hand mode.

EXAMPLE: Fig#2A
The Start float indicator is illumi-
The Stop float indicator light is not.
Illustration (Fig#3A) shows the Stop float is activated, but the indicator light on the command center in (Fig#2A) is not illuminated. The Stop float is not working properly and should be replaced.

EXAMPLE: Fig#2B The
same indicator lights are illuminated.

The Start float indicator is illumi-
The Stop float indicator light is not.

Example (Fig#3B) shown below is demonstrating that the same float is not working, but for a different reason. In this example the float is hung up in the tank.
