Outputs

Pump Output (4 Amps @ 12VDC)

The TD-1000 features one output that can control an interposing relay for a pump, such as a waste tank discharge pump. An auto-off feature is standard and programmable to prevent damage from a pump running dry.

Alarm Output (300mA @ 12VDC)

The alarm output can be programmed to activate a relay when the waste tank reaches a set alarm point. It can also be used to disable the toilet or activate a buzzer (buzzer supplied).

TD-1000 Wiring

Connector Wiring:

Red = Battery +
Black = Battery -
Green = Sensor In
Purple = Sensor +
White = Output +
Black = Sensor -
Blue = Buzzer +
Black = Buzzer -

Mounting

Drill a 50mm hole using a 50mm hole saw. The unit size is 75mm x 75mm.

Pump Circuit Connection

Connect the White wire to the relay for the pump. The circuit should be wired to the battery and pump.

Toilet Disable Connection

Connect the Blue wire to a relay for toilet disable functionality. Alternatively, connect the blue output wire to a SmartSwitch STS-220 toilet controller as shown.

Programming Instructions

Step 1: Placing the unit in Program Mode

Press and hold the Scroll key, then press and hold the Mute key simultaneously for 3 seconds.

The display will show the SET-UP MENU with options like: Program Tank, Calibrate, Set Alarm, More. Press the Enter/Pump button to select a tank name or scroll to another function.

Step 2: Selecting Tank Name

The display will show: SET-UP MENU Black Tank, Aft Black, Fwd Black, More. Press the Enter button to select the tank name or scroll to another name.

Please see page 8 for sensor calibration.

Step 3: Setting the Alarm Point

The display will show: Set Alarm 0%. Use the Scroll or Mute key to adjust the alarm point to the desired level (e.g., almost empty, almost full). Press the Enter key to set the alarm point.

Step 4: Audible Alarm On / Off (default is On)

The display will show: Alarm On/Off. Press the Enter Key to toggle the alarm between On and Off.

Step 5: Pump Off

The display will show: Set Pump Off 10%. Use the Scroll or Mute key to move the Pump Off point to the desired level. Press the Enter key to set this as your Pump Off point.

If the Pump key is pressed, the pump output will turn on and automatically turn off when the Pump Off point is reached. If the tank name is Black or Grey, the pump stops when the tank level is equal to or less than the programmed stop point. If the tank name is Fresh or Fuel, the pump stops when the tank level is equal to or greater than the programmed stop point.

Disable Toilet:

To use the Alarm Output as a Toilet Disable control, scroll to "Toilet En/Dis" from the Set-Up Menu and press the Enter key. Repeat to revert to an Alarm output.

Exit Menu

Scroll to Exit and press the Enter key.

Sensor Installation

WARNING!

For sensor Model SEN-100, the maximum tank height is 1 Meter.
For sensor Model SEN-250, the maximum tank height is 2.5 Meters.
The maximum surge and safe pressure is 28psi. Refer to "Calibration Tips & Tricks" on www.smartswitch.co.nz for more information.

Mounting Adaptors Available:

A range of mounting adaptors are available, including flat sidewall, top mount, 1.5" pipe, 2" pipe, 3" pipe, and drain valve adaptors. Contact your dealer for details.

If using a 4 to 20-milliamp loop sensor from another manufacturer, the adaptor (part number SM-420) will be required.

Sensor Installation:

Mount the sensor as low as possible in the sidewall using a 3/4" spin-in or the flat sensor adaptor. If using the flat sensor adaptor, drill a 5/8" hole in the sidewall. Apply silicon glue liberally to the bottom of the adaptor. Use #10 x 3/4" stainless steel self-tapping screws to attach the adaptor. Ensure the hole in the adaptor is clear of excess glue. Allow glue to dry according to its instructions. Wrap the sensor threads with Teflon plumbers tape and install the sensor, tightening by hand. Avoid installing the sensor in the bottom of the tank to prevent debris collection.

Top Mount Adaptor:

Requires a 3/4" ABS or PVC pipe cut to length, extending about 1/2" from the bottom of the tank. Glue the pipe into the adaptor and screw the sensor into the top of the adaptor. Secure with 2 self-tapping screws. Seal sensor threads with Teflon tape and ensure no air leaks, as the tube must remain pressurized.

Pipe Adaptor:

The sensor can be damaged by over-pressure during installation if the air gap between the sensor and the ball valve is compressed. DO NOT PRESSURIZE TANK WITH SENSOR FITTED.

Sidewall Adaptor:

Apply silicon glue liberally to the bottom of the adaptor. Using #10 x 3/4" stainless steel self-tapping screws attach the adaptor to the sidewall. Once the adaptor is attached make sure that the hole in the adaptor is clear of any excess glue. Allow drying as per the instructions for the glue. Wrap the threads of the sensor using Teflon plumbers tape and install the sensor. Tighten by hand.

Sensor Programming Instructions

Press and hold the Scroll key, then press and hold the Mute key simultaneously for 3 seconds to access the Set-Up Menu.

From the SET-UP MENU (Program Tank, Calibrate, Set Alarm, More), use the Scroll or Backlight key to select "Calibrate" and press the ENTER Key to access the Calibrate Menu.

The display will show: 2 Point / 5 Point Calibration. Use the Scroll key to switch between them, then press the Enter key.

2 Point Calibration: (Bottom & Top)

The display will show: Set Low Level Input = ??????? V. Fill the tank to the required TANK LOW LEVEL (minimum suggested is liquid just covering the sensor). Wait approximately 60 seconds for the fluid to settle, then press the Enter key. The display will show "Setting Level Please Wait".

The display will then show: Set High Level Input = ??????? V. Fill the tank to the TANK HIGH LEVEL. Wait approximately 60 seconds for the fluid to settle, then press the Enter key. The display will show "Setting Level Please Wait".

If no fluid is added, the display will show: "The High Level is not greater than the Low level".

For more information, see "Calibration Tips & Tricks" on www.smartswitch.co.nz.

5 Point Calibration: (Bottom, 1/4, 1/2, 3/4 & Top)

The display will show: Set Low Level Input = ??????? V. Fill the tank to the required TANK LOW LEVEL (minimum suggested is liquid just covering the sensor). Wait approximately 60 seconds for the fluid to settle, then press the Pump key. The display will show "Setting Level Please Wait".

The display will then show: Set 1/4 Level Input = ??????? V. Fill the tank to the 1/4 LEVEL. Wait approximately 60 seconds for the fluid to settle, then press the Enter key. The display will show "Setting 1/4 Please Wait".

The display will then show: Set 1/2 Level Input = ??????? V. Fill the tank to the 1/2 LEVEL. Wait approximately 60 seconds for the fluid to settle, then press the Enter key. The display will show "Setting 1/2 Please Wait".

The display will then show: Set 3/4 Level Input = ??????? V. Fill the tank to the 3/4 LEVEL. Wait approximately 60 seconds for the fluid to settle, then press the Enter key. The display will show "Setting 3/4 Please Wait".

The display will then show: Set Full Point Input = ?.?? v. Fill the tank to the FULL LEVEL. Wait approximately 60 seconds for the fluid to settle, then press the Enter key. The display will show "Setting Level Please Wait".

If no fluid is added between steps, the display will show: "The ??? Level is not greater than the Low level".
