Table 23 Fault Actions - Kohler Curtis F Series Manual

Return to TOC
FAULT ACTIONS
The fault actions (effect of fault) in Table 23 use the action code bits individually or when combined as
listed in the fault action column in Table 24. The variable System_Action (0x4E00), which is available
in the CIT Programmer List View ( ), or TACT, returns the decimal number corresponding to the
active fault action bit(s). The example illustrates how to determine and plan for faults in both single
and dual motor applications.

Curtis AC F2-A, F4-A, F6-A Motor Controllers – FOS 4.5 – April 2022
Bit(s)
1 Disables the motor.
Shut down the Main contactor.
2 Opens the main by de-energizing the main
contactor driver, only if Main Enable = On.
Shut down the EM Brake.
3 Sets the EM Brake by de-energizing the driver, only
if the parameter Set EM Brake On Fault = On.
4 Set the Throttle_Command = 0%.
5 Set the Interlock_State = Off.
6 Shut Down Driver1 (e.g., turn off the driver's PWM).
7 Shut Down Driver2 (e.g., turn off the driver's PWM).
8 Shut Down Driver3 (e.g., turn off the driver's PWM).
9 Shut Down Driver4 (e.g., turn off the driver's PWM).
10 Shut down Proportional Driver (legacy name).
11 Set the Brake_Command = 100%.
12 Disables the pump.
13 Disable Dual Drive trim calculation.
For a Dual Drive system, one controller has a severe
14 fault but the main contactor must stay closed so the
other controller can continue to operate.
15 Steer angle = 0° (Dual Drive applicable).
For a Dual Drive system, it uses the max speed set
16
by the Dual_LOS_Max_Speed parameter.
17 Shut Down Driver 5 (e.g., turn off the driver's PWM).
Shut Down Driver 6 (as applicable to the controller;
18
e.g., turn off the driver's PWM).
Shut Down Driver 7 (as applicable to the controller;
19
e.g., turn off the driver's PWM).
Shuts down (turns off) the Coil Supply (return)
20 voltage. (Note, based upon the controller model, this
will also shut down the low-side drivers).
25, 12, 11, 4, 3, 2, 1 Evokes all Fault Actions as per the indicated bits.
