To change between Air / Fuel and lambda readings:
Turn the key on so the gauge and BIM-13-2 are powered.
Press and hold the setup/status switch on the BIM-13-2. The status light will slowly flash red and green.
After about 10 seconds the status light will begin flashing rapidly. Release the switch.
The reading will now be changed.
To set or change the ID number:
The ID will not normally need to be changed. A green-red-red flash on the BIM-13-2 status light indicates an ID
conflict with another connected BIM. The following procedure will allow the BIM-13-2 to automatically select a new,
unused ID.
Press and hold the setup/status switch on the BIM-13-2 while turning the key on. The BIM status light will be
steady RED.
Release the switch.
When the status light begins flashing, it is finished.
This module does not use warning points, so the warning setup is used to program the display range matching
your wide band controller analog output. These settings are changed on the gauge system display. Common
settings are listed on the front page of the manual.
Only VFD3/3X controls with a plastic case support adding BIM's.
For VFD3, VFD3X, and VHX systems follow these steps:
Make sure the BIM units are all connected to the gauge control box.
Hold the SW1 switch from the gauge system control box while turning the key on. The message display should
show SETUP.
Release SW1.
Press and release SW1 until BIM is shown on the message display.
Press and hold SW1. The message display should show SCAN followed by the number of BIM channels
detected. Release SW1.
If 0 is shown, check all connections and then press and hold SW1 with SCAN shown to retry reading the modules.
Otherwise, if any other number is shown, press and release SW1 until SETUP is shown.
Press and hold SW1 until the speed display shows " – " or the message changes.
Release SW1. On the VFD3 systems the message display will show the label assigned to the first channel found
and the speed display will show "C" followed by the channel ID number. On the VHX systems the message
display will show "CH" followed by the channel ID number on one line and the label currently assigned on the
second line.
Press and release SW1 until the desired channel ID number is shown.
Press and hold SW1. The message display will show "LABEL".
Release SW1. The message display will show the label assigned to this channel.
This label cannot be changed, so press and hold SW1. The message display will show "WARN".
Release SW1. The message display will show "L" followed by the current 0 volt display setting.
Press and release SW1 to change the 0 V display setting to the desired value.
Press and hold SW1 until the speed display shows " – ".
Release SW1. The message display will show "H" followed by the current 5 volt display setting.
Press and release SW1 to change the 5 V display setting to the desired value.
Press and hold SW1. The message display will now show "DONE".
This can be repeated for additional channels, or the key can be turned off to exit setup.
