Feedback 2 Range Fault This fault indicates that the voltage on the LVDT/RVDT 2A or 2B inputs has exceeded the normal voltage range by the Feedback Range Threshold value. The normal voltage range is determined during calibration. For example, suppose that the voltage on the LVDT/RVDT 2A input changed from 2 volts to 6 volts during the calibration procedure, and Feedback Range Threshold is 0.3 V. A Feedback 2 Range fault will occur if the voltage on the LVDT/RVDT 2A input is less than 1.7 V or greater than 6.3 V. Type (alarm or shutdown): alarm Latching/non-latching response: configurable
Feedback Tracking Fault 1
This fault indicates that the difference between Position 1 and Position 2 exceeds the Tracking Fault 1 Threshold for longer than the Tracking Fault 1 Delay time.
Type (alarm or shutdown): alarm
Latching/non-latching response: configurable Feedback Tracking Fault 2
This fault indicates that the difference between Position 1 and Position 2 exceeds the Tracking Fault 2 Threshold for longer than the Tracking Fault 2 Delay time.
Type (alarm or shutdown): configurable
Latching/non-latching response: configurable
Input Voltage Out of Range
This Shutdown indicates that the SPC input voltage is below 17 V (dc) or above 33 V (dc).
Type : Shutdown
Latching/non-latching response: latching Internal Fault
This Shutdown indicates that an internal problem with the SPC has occurred. If this shutdown is still present after turning power to the SPC off, then on, the SPC is faulty and must be replaced.
Type : Shutdown
Latching/non-latching response: latching
