5.7.9 Fault Latch
The Fault Latch function allows specific faults to become “latched” after the automatic fault reset attempts (L09-02)
has maxed out. The Reset key on the keypad will be blocked from clearing the fault, and the fault can only be
cleared by the methods explained below. In the case of a power loss, the fault will remain latched when power is
restored.
A latched fault can be cleared in three ways:
1. The recommended method is to program an MFDI (H01-xx) to 48 (Flt Latch Reset). The digital input must be
toggled (ON and then OFF) in order for the fault to clear. Since this feature is intended for safety, a key switch
is recommended. This will prevent a recurring fault from being continuously cleared and ignored.
2. Clear the fault using the Monitor tool within IMPULSE
®
•Link.
3. The F1 or F2 keypad key can be programmed to H01-09 or H01-10 = 48 (Flt Latch Reset). When a fault is
latched, pressing the F1 or F2 key twice will reset the fault.
NOTE:
An MFDI and F1/F2 keys are allowed to be programmed after a fault is latched.
Table 5-105: Fault Latch Parameter Settings
* To program parameters L09-07 and L09-08, refer to the Auto Fault Reset example. The same programming method applies here.
