Pump Output: (also see Pump Start / Stop: page 10 )
The TD-4000 has two Pump Output controls and works as follows:
If used for Black or Grey you can turn it ON and OFF manually. If the pump is ON will turn OFF automatically when the tank is empty or at the programmed Pump Stop Point.
If used for Water you can turn it ON and OFF manually. If the pump is ON it will turn OFF automatically when the tank reaches the programmed low alarm point or at the programmed Pump Stop Point.
If used for Fuel you can turn ON and OFF manually. If the pump is ON it will turn OFF automatically when the tank is full or at the programmed Pump Stop Point.
If a tank type has been programmed as a Day Fuel (see Step 4) the Output will automatically turn ON at the programmed Pump Start Point and turn OFF when the tank is full or at the programmed Pump Stop Point. If the Pump key is pushed during the automatic pumping the pump will stop and the Day Tank feature will be placed into manual mode Pushing the pump key again will start the pump again and place it back into automatic mode.
Special Pump:
If the Black tank has a charcoal filter fitted and you are using a pressure sensor you will need to use this feature.
Explanation: When the pump is turned on liquid is removed from the tank quicker than air can replace it due to the constrictive nature of the air filter. This will cause a pressure drop, the system will think the tank is empty and turn the pump off.
The Special Pump feature will allow the pump to run for a pre-set time without looking at the tank level (which will be wrong due to the above reason), the pump will then turn Off for 20 seconds allowing the tank to equalize its pressure. The system will then look at the tank level and turn the pump back On for a time period. This time will be based on the tank level e.g. If the tank level is low, the time period will be short. This will continue until the tank is empty.
If this feature is selected then, when the pump is On, the display will show ——PUMPING——.
When the pump is Off, during the equalizing time, the display will show ——EQUALIZING——.
Scroll down to “Special Pump” and press the Pump key.
The display will now show:

For more information see “Calibration Tips & Tricks” on our web site www.smartswitch.co.nz
Mounting Adaptors Available:
A range of mounting adaptors are available which includes flat sidewall, top mount, 1.5” pipe, 2” pipe, 3” pipe and drain valve. Ask your dealer for details.
Sensor Installation:
The sensor should be mounted as low in the sidewall as possible using a ¾” spin-in or the flat sensor adaptor. If the sensor adaptor is used it will require drilling a 5/8” hole in the sidewall. Apply silicon glue liberally to the bottom of the adaptor. Using #10 x ½” 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. It is not recommended to install the sensor in the bottom of the tank. Although the sensor will operate correctly it will provide an area for debris to collect which would be difficult to flush out.The top-mounting adaptor requires 3/4″ ABS or PVC pipe cut to the proper length so that the pipe is about 1/2″ from the bottom of the tank. This pipe glues into the adaptor and the sensor screws into the top of the adaptor. It is held on with 2 self-tapping screws. Care must be taken that the sensor threads are sealed with Teflon tape and screwed in tight to ensure no air leaks, as the tube must remain pressurized. The sensor will be damaged if subject to over pressure during installation, caused by compressing the small air gap between the sensor and the ball valve.
DO NOT PRESSURIZE TANK WITH SENSOR FITTED

Table 1:
Smart Switch strongly recommends that Table 1 be filled out at time of tank calibration when a Pressure sender is being used.
These voltages will be displayed during the calibration setup.
Reason: Should the TD-4000 ever need to be replaced all tanks will need to be re-calibrated, but if table 1 has been filled out then creating these input voltages can be done without even the tank sender connected,making the process very simple.
