• 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.
• Should a 4 to 20-milliamp loop sensor supplied by another manufacturer be used, then the adaptor (part number SM-420) will need to be installed.

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.

Sensor Programming Instructions

• Two different methods of tank programming are available if using the pressure sensor:
• 2 Point Calibration: sets tank low and tank high points which can only be used if the tank is a regular size and shape.
• 5 Point Calibration: sets tank low, tank quarter, tank half, tank three quarters and tank full points, offering more accuracy if the tank is an irregular size and shape.

2 Point Calibration

• Turn Rotary Switch on the I/O Box to position 0
• When calibration mode is entered (holding down the program button for 3 seconds) the LED will flash very fast, while the I/O Box is calculating the Empty point. Once this has finished you will see Three slow flashes and the LED will stay on indicating it has programmed the Empty point. It is now ready to set the Full point.
• When the button is pressed again, to set the Full point, the LED will flash very fast, while the I/O Box is calculating the Full point. Once this has finished you will see Three slow flashes indicating it has programmed the Full point. The LED will then turn off.
• NOTE: While the fast flashing continues it is indicating the tank contents have not settled enough for the unit to take a good reading (wait for the contents to settle).
• NOTE: If you see 12 slow flashes this indicates the unit could not see any difference between the Empty point setting and the Full point setting. The Empty and Full points need to be different.
• Turn Rotary Switch to correct position (see Setting Rotary Switch)

Note: The Bottom Only, Top Only and Setting The Calibration From One IOU To Another, only applies to HT-100 or HT-100P units with manufacture dates after March 2007.

• After calibrating the bottom and top settings of a tank you may wish to go back and change either of these settings individually:

• The Bottom Only setting can be changed by turning the Rotary Switch to position A

• Fill the tank to the required TANK LOW LEVEL, minimum suggested is liquid just covering the sensor. Wait approx. 30 seconds for the fluid to settle. Press and hold down the Program Button (on the IOU) until the LED comes on (approx. 3 seconds), this will set the tank low point. Press and release the program button, the LED will give 3 quick flashes. The tank low point has now been saved and the unit will automatically leave program mode. The device is now ready for use.

• Turn Rotary Switch to correct position (see Setting Rotary Switch 15)

• The Top Only setting can be changed by turning the Rotary Switch to position B

• Fill the tank to the required TANK FULL LEVEL and wait approx. 30 seconds for the fluid to settle. Press
  and hold down the Program Button (on the IOU) until the LED comes on (approx. 3 seconds), this will set the tank high point. Press and release the Program Button, the LED will give 3 quick flashes. The tank high point has now been saved and the unit will automatically leave program mode. The device is now ready for use.

• Turn Rotary Switch to correct position (see Setting Rotary Switch page 15)

5 Point Calibration

• Turn Rotary Switch on the I/O Box to position F
• When calibration mode is entered (holding down the program button for 3 seconds) the LED will flash very fast, while the I/O Box is calculating the Empty point. Once this has finished you will see Six slow flashes and the LED will stay on indicating it has programmed the Empty point. It is now ready to set the 1/4 point.
• When the button is pressed again, to set the 1/4 point, the LED will flash very fast, while the I/O Box is calculating the 1/4 point. Once this has finished you will see Two slow flashes indicating it has programmed the 1/4 point. The LED will stay on indicating it has programmed the 1/4 point. It is now ready to set the 1/2 point.
• When the button is pressed again, to set the 1/2 point, the LED will flash very fast, while the I/O Box is calculating the 1/2 point. Once this has finished you will see Three slow flashes indicating it has programmed the 1/2 point. The LED will stay on indicating it has programmed the 1/2 point. It is now ready to set the 3/4 point.
• When the button is pressed again, to set the 3/4 point, the LED will flash very fast, while the I/O Box is calculating the 3/4 point. Once this has finished you will see Four slow flashes indicating it has programmed the 3/4 point. The LED will stay on indicating it has programmed the 3/4 point. It is now ready to set the Full point.
• When the button is pressed again, to set the Full point, the LED will flash very fast, while the I/O Box is calculating the Full point. Once this has finished you will see Five flashes indicating it has programmed the Full point. The LED will then turn off.
• NOTE: While the fast flashing continues it is indicating the tank contents have not settled enough for the unit to take a good reading (wait for the contents to settle).
• Turn Rotary Switch to correct position (see Setting Rotary Switch)

Setting The Calibration From One Input/Output Unit To Another

• Once the IO/Box has been calibrated you can transmit the calibration settings from that unit to as many more as required (tanks would need to be the same shape, size and content).
• The I/O Box can transmit to, or receive from, any I/O Box and vice versa.
• Note: This must be done independently from the complete system setup (only the 2 IOU’s connected).
• Step 1: Connect the power and network cable to both units.
• Step 2: Turn the Rotary Switch to position C for the master transmitter (the unit that is calibrated).
• Step 3: Turn the Rotary Switch to position D for the slave receiver (the unit that needs calibrating).
• You will see both LED’S flashing, please wait (approx 20 seconds) for the LED’S to stop flashing, the slave receiver now has the same calibration setting as the master transmitter.
• For more information see “Calibration Tips & Tricks” on our web site www.smartswitch.co.nz.
