Status Codes
During normal operation
21 TPC is ready to run, no hook signal is detected, and low priority
31 TPC is ready to run, a hook signal is detected, and low priority
61 TPC is ready to run, no hook signal is detected, and priority
71 TPC is ready to run, a hook signal is detected, and priority
See chapter 3 “Level management” for details on “priority” and “low priority.”
● If the Status code is an even number this indicates the TPC is not detected by the TS-TPI. This
indicates a communication problem between the TS-TPI and the TPC.
● If the last digit is greater than 8, the TPC is in an alarm condition. See the Fault code on ATG
display and compare it with the table for the particular model controller in use or see the
troubleshooting guide in the Installation and Owner’s manual for the specific TPC.
● If the last digit is 5 the TPC is in calibration mode
● If the last digit is 3 the controller needs help (master/slave and alternating configurations only)
● For specific code interperatation please contact INCON Technical Support.
