Filter/Motor Indicator LED
|Filter LED||FL||geen||Noe||Indicates normal operation until filter pressure drop exceeds|
|Yellow||Change Filter||indicates filter pressure drop has exceeded calibrated setting (factoryset at 1.5x clean filter pressure)|
|Motor LED||ML||Green||None||Indicates normal motor operation when the static pressure is above 0.2" w.g|
|Red||Troubleshoot motor||Indicates motor is not in operation, and that unit static pressure is below 0.2"w.g.|
STEP 1: Remove filter from box by following the instructions found on page 23 of this installation manual.
STEP2: Take LED cable assembly out of FFU-HE Plenum
STEP3: Remove well nut in genter port of BTR filter.
SSTEP 6: Put lock washer and threaded standoff back on cable and tighten to LED.
STEP 7: With two(2)people holding the unit, pull cable back through plenum until plenum can rest on top of filter.
STEP 8: Refer to BTR Filter instruction found on page 13 for proper filter installation.
STEP 9: Refer to wiring diagram(Located in control box) to connect to the BFC controller instead of the terminal block.
All pressure transducers are factoty calibrated. If a different pressure transducer set point is desired.
|Motor||MBAS||Troubleshoot Motor||Closes a dry contact to let the signal pass through when the static pressure is less than 0.2w.g. indicating the motor is not operating|
|Filter||FBAS||Change Filter||Closes a dry contact to let the BAS signal pass through when the static pressure is greater than the calibrated pressure drop(factory set at 1.5x clean filter).|
Unit will come factory calibrated; no additional field modifications are required.
