DI#2 has been programmed as a fault type digital input and input indicates
a fault condition is present.
Verify that the appropriate Digital Input Configuration parameter has been
programmed correctly.
F61 External Fault on DI#2
Input
Verify wiring and level of input.
DI#3 input has been programmed as a fault type digital input and input
indicates a fault condition is present.
Verify that the appropriate Digital Input Configuration parameter has been
programmed correctly.
F62 External Fault on DI#3
input
Verify wiring and level of input.
Based on the Analog Input parameter settings, the analog input level has
either exceeded or dropped below the Analog Input Trip Level setting
(P46/ I/O08) for longer than the Analog Input Trip Delay time
(P47/ I/O09).
Measure value of analog input to verify correct reading.
Verify settings of all Analog Input parameters (P45-P49/ I/O07- I/O 11).
Verify correct positioning of input jumper JP3 (Voltage or Current) on the
MX control card.
F71 Analog Input Level Fault
Trip.
Verify correct grounding of analog input connection to prevent noise or
ground loops from affecting input.
Indicates that communication has been lost with the remote keypad.
(This fault normally occurs if the remote keypad is disconnected while the
MX control card is powered up. Only connect and disconnect a remote
keypad when the control power is off.)
Verify that the remote keypad cable has not been damaged and that its
connectors are firmly seated at both the keypad and the MX control card.
Verify that the display interface card (when present) is firmly attached to
MX control card.
F81 SPI Communication Fault
Route keypad cables away from high power and/or high noise areas to
reduce possible electrical noise pickup.
Indicates that the starter has lost serial communications. Fault occurs
when the starter has not received a valid serial communications within the
Communication Timeout parameter (P59/FUN12) defined time.
Verify communication parameter settings (P59-P61/ FUN 10- FUN12).
Check wiring between the remote network and the MX control card.
F82 Modbus Timeout Fault
Examine remote system for cause of communication loss.
Typically occurs when attempting to run a version of control software that
is incompatible with the MX control card hardware being used. Verify
that the software is a correct version for the MX control card being used.
Consult factory for more details.
F94 CPU Error – SW fault
Fault can also occur if the MX control has detected an internal software
problem. Consult factory.
