49 1 Parameter A parameter value or the software was 1. A parameter was changed that requires Cycle KSI. Shutdown. 1 = Stop.
Change Fault changed that required a power cycle. a power cycle. See PCF column in Sec. 3
This fault is set automatically to force (Programmable Parameter Menus) to
the vehicle operator to cycle power, for identify the parameters that will cause
safety purposes. a parameter change fault.
2. A new software application was loaded
that caused the parameter values to be
overwritten, requiring a power cycle.
3. A device using the serial interface
(such as the 1313) is requesting an
out-of-range parameter change.
51 1 Interlock
1. When the interlock switch inputs Interlock Input 1 = Interlock Input 3. Interlock Input Interlock = Off. 1 = Stop.
Switch are a crossed configuration (N.O. and The fault is checked only when Interlock 1 <> Interlock
Supervision N.C.), the two inputs are checked. Type = 2 (crossed polarity). Input 3.
A fault is set if Switch 1 (pin 9) =
Switch 3 (pin 11).
2. Interlock switch defective.
