DFR INFORMATION
DFR’s (Drive Fault Records)
The AC MCB (Motor Control Board) monitors the drive system and reports any anomalies by
triggering what is called a DFR (Drive Fault Record) code.
Same Codes, Different Meanings
The AC System has the same codes as the DC system but the meanings may not necessarily be the
same, specifically “CHECK SPEED SYSTEM” and “CHECK MOTOR SYSTEM”. You must now take
in to account that the MCB may have issued a DFR code which has shut the treadmill down and
display one of the “CHECK” codes. In most cases you will find that a DFR code has been flagged and
caused the unit to shut down.
How Do You Know What or If a DFR Code Has Been Captured?
There are two ways to check to see if a DFR code has been captured:
1. Check the LAST ERROR LIST in the Maintenance Mode
•
Engage the Maintenance Mode and access the LAST ERROR LIST
(see “LAST ERROR LIST” in the “MAINTENANCE MODES – TEST MODES” section)
•
Scroll the parameters until you come to the LAST DFR
•
There will be an 8 digit number that is the DFR code
Example: LAST DFR(X) 00004000 (over temp on motor or drive).
o
Ignore the first set of zero’s before the number. This example will be
considered a 4000 code
o
If the Last DFR list reads LAST DFR(X)00000000, a DFR has not been
recorded by the MCB and reported to the display. Follow the appropriate
troubleshooting steps for the code displayed (i.e. ELEVATION STALL, etc.)
2. Count the blinks from the Status led’s on the MCB
•
When the MCB records a DFR, the three Status
led’s (Led 1, Led 2 and Led 3) will blink together
simultaneously
•
The Status led’s will blink the number of times
that indicate the particular DFR code
•
There will be a short pause in the blinking to
show counting separation (Count the blinks
between the pauses)
Example: Count 15 blinks, pause, 15 blinks
again would indicate a 4000 DFR code, which is
an “over temp on motor or drive”
*See DFR Code Chart in the “Troubleshooting” section, for blink reference chart.
