Display will read SND signaling to select a sender type. Press SW1 to move through
list forward, press SW2 to back up. Press both switches to save setting. The supported
senders are listed below with the display that represents each option.

If BUS is selected, the display will read the current BIM mode. Press SW1 to move through
list forward, press SW2 to back up. Press both switches to save setting. The supported
senders are listed below with the display that represents each option.

If BUS is selected, following the BIM mode selection, the display will show dIs and then allow a high
speed disable to be set or turned off. The speed will be shown in MPH when the temperature is
Fahrenheit or km/h when using Celsius. Use SW1 or SW2 to set the speed at which the fan should turn
off. Press both switches to save the setting.

If your gauge is not supported in one of the options above, you will need to custom calibrate the controller for your
gauge. (if CUS is selected and calibration has not been done, the calibration sequence will automatically be
started). The following is the procedure for custom calibration. If your gauge system is listed above, skip this
portion and continue at Step 12.
Custom Calibration
Note 1: If your engine is warm you may need to disconnect the wire from your sender in order get to the lower
points on the gauge.
Note 2: If the key is turned off in custom setup, the previous gauge setting will be used and the custom gauge will
not be saved.
Note 3: If your gauge does not have defined ticks with numerical temp readings, it is highly recommended to use
a dedicated sender as calibration to the gauge is very inaccurate or impossible without temp markings.
CC1. Select CAL in Step 9 on the previous page. Display will read ADJ.
CC2. Turn the potentiometer on the lower right corner of the unit (marked CUSTOM ADJUSTMENT) with a
small flat screw driver. While doing so, watch your temp gauge and line up the needle with the lowest
temperature tick on the gauge. Custom gauge must be calibrated starting at cold temperatures and
moving to hot temperatures.
Note: Turning potentiometer clockwise increases temperature reading.
CC3. Once the gauge is set to a tick, press SW1 or SW2. A temperature reading will appear on the display.
Scroll to the temp reading that matches the tick temperature reading on the gauge using SW1 to increase
and SW2 to decrease. Press both buttons to save the number. Display will again read ADJ.
CC4. Repeat steps CC2 and CC3 with the next lowest tick on gauge until all the ticks on your gauge have been
set. (up to 6 but no less than 4 points). Press both SW1 and SW2 at ADJ to stop setting points if there
are less than 6 points on your gauge. If there are more than 6 points on your gauge, select points over
the full range of the gauge (cold to hot). This will give a better match to your gauge.

Unit will flash 888 to indicate set up is complete. The unit now has been set up. If the wiring and setup have been
properly completed the unit should begin normal operation at this point.
Option
Automatically select the bus operation mode.
Connect to a VHX, VFD3 (SE47 or higher), or VFD3X (SE56 or higher) system.
Connect to a VFD3 (SE46 or earlier) or VFD3X (SE55 or earlier) system.
PAC-2750 is a master connected to a BIM-01-1 or similar unit.
