Configure the Tachometer Expansion Module Chapter 5
Speed High Limit 0.0 ≤ Speed High Limit 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.
Speed Low Limit 0.0 ≤ Speed Low Limit 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.
Tach Expansion Module Fault Checked (1)
Unchecked (0)
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.
