Comments
Enter the high-speed limit. The value must be greater than the
Speed Low Limit.
When enabled (checked), the tachometer signals a fault when
the measured speed is outside the specified Speed High / Speed
Low limits.
Enter the low speed limit. The value must be lower than the
Speed High Limit.
When enabled (checked), the tachometer signals a fault when
the measured speed is outside the specified Speed High / Speed
Low limits.
When enabled (checked), the tachometer signals a fault when
the tachometer expansion module is in fault.
If a module fault is detected, if possible, the TSC module
continues to provide a signal to its various tacho outputs. For
example, as a communication link timeout, which does not
preclude the function of the module. Set the Tach Expansion
Module Fault to communicate these detected module faults as
a tacho sensor fault.
