Error 5 4; Error 5 5; Error 5 6; Error 5 7 - Bodyguard T-30 User Manual

8.5.4 ERROR 54
DESCRIPTION:
The Relay on the M.C.B. is signaling that it is closed when it should be open.
ACTIONS:
Defective Relay on the M.C.B.. An "A" on the M.C.B.'s L.E.D. confirms this. Change M.C.B.
8.5.5 ERROR 55
DESCRIPTION:
Hardware current limit has been exceeded for a very short period of time.
ACTIONS:
There is too much current but not high enough to represent a short-circuit (Error 52).
This can be created by holding back the running belt. Check that nothing is jamming the walking belt,
rollers, drive belt or motor from turning or that the drive belt and walking belt tensions are not far too
tight. A defective component on the M.C.B. may also cause this requiring a change of the M.C.B.
8.5.6 ERROR 56
DESCRIPTION:
Walking Belt Speed Incorrect
ACTIONS:
If the actual belt speed is less than 80% or more than 120% of the required speed for more than 5
seconds then an Error 56 will appear. e.g. if the required speed is 5 mph, then an Error 56 will appear
if the actual speed reading is less than 4.0mph or greater than 6.0mph. (+ or -20% for 5 seconds)
Check if something is causing the walking belt, rollers, drive belt or motor from turning. If not, it is
possibly a fault on the M.C.B. and if it occurs repeatedly then it may need to be changed.
8.5.7 ERROR 57
DESCRIPTION:
Error 57 is caused by an Open Circuit detected from the Drive Motor on the M.C.B.
ACTIONS:
Check the motor wires (+ & -) are correctly attached to the M.C.B.
Check the motor brushes are touching the commutator. Are they worn? If so, clean with fine
sandpaper and reinsert. Test. You may need to replace the motor brushes. Use a 9V battery to test
the motor. Remove the Drive Belt that is connected to the Drive Motor Pulley and place the motor
wires on the battery terminals, the motor should spin. The motor will not spin if you have not removed
the Drive Belt.
Check the resistance of the motor by using a Multimeter. Place one pin in each motor wire connector.
You should get a reading between 1 & 2 OHMS. If you get an extremely high reading on the
Multimeter or the letters "OL" (Overload), there is possibly a problem with the motor.
8.5.8 ERROR 60
DESCRIPTION:
Extreme Amperage Warning
ACTIONS:
Refer to section 6.18 for detailed instructions.
8.5.9

ERROR 100

DESCRIPTION:
Standard Code for an unrecognizable error from the M.C.B.
ACTIONS:
No specific diagnosis – Most common solution is to change the M.C.B. if problem repeats
consistently.
