23.12 Troubleshooting Phase Trigger Channels
A Phase Trigger can have several different operation states which will result in different readings and
status errors as shown in the following figures and summarized in Table 23-6.
Figure 23-3) Phase Trigger is OK
Figure 23-4) Phase Trigger Transducer Fault
Figure 23-5) No Phase Trigger Pulses Figure 23-6) Phase Trigger Triggering Error
WARNING!
A reading of 0 rpm with the “No Pulses” fault is an unknown machine condition. The machine
may still be running but a transducer fault has occurred.
Status Speed Description Action
OK
Current Speed
The Phase Trigger signal is
triggering correctly.
No action required.
Fault
Invalid
The input Phase Trigger signal is
outside the configured range
check.
This may be due to a faulty transducer or incorrect
configuration. Verify the transducer Gap value is
inside the configured OK limits. Repair transducer
or adjust OK limits as required.
No Pulses
0
The system has not received a
valid Phase Trigger pulse within
the timeout.
Either the machine has stopped, or the triggering
configuration is incorrect. If the machine is
running, view the Phase Trigger signal in
SETPOINT CMS or on an oscilloscope and review
the triggering configuration.
Triggering
Error
Invalid
The system is receiving sporadic
Phase Trigger pulses and
cannot determine the speed.
View the Phase Trigger signal in SETPOINT CMS
or on an oscilloscope and review the triggering
configuration.
