Type Enable Potential causes and corrective actions
A SOP Cause
One or two of the redundant Hall Effect power supplies has failed. This
alarm is enabled when the SOP flag RedHallEfectPwrSupFailEn_O is
set true. This should only be done for systems which use redundant Hall
Effect power supplies.
Action
1. Verify that both power supplies to the DCR for the Hall Effect sensors is
no greater than -10 % of the specified output (+/- 15 VDC or +/-24 VDC
depending on the version chosen).
2. Check the physical condition and connections of the power supplies
wiring harness.
3. Check connection of DB50 cable at the DCR (J3) and the SIB (P1)
4. Check the condition of the DB50 cable between the DCR and the SIB,
ensure continuity of conductors for pins 41 to 50 from one connector
to through to the other side
5. If the above steps do not resolve the issue, contact Siemens customer
service.
A SOP Cause
One or two of the redundant main power supplies has failed. This alarm is
enabled when the SOP flag RedMainPwrSupFailEn_O is set true. This
should only be done for systems which use redundant main power sup‐
plies.
Action
1. Verify that both redundant power supplies to the DCR are operating
correctly.
– 90 to 264 VAC, 47 to 63 Hz input
– 12 VDC no greater than -10% of specified output
2. Check the physical condition and connections of the power supply
wiring harness.
3. If the above steps do not resolve the issue, contact Siemens customer
service.
F Fixed Cause
ERRATA: The Fault display text '15V or -15V Power Fail' is incdorrect in the
Event Log, Fault Log, on the Keypad, and on the Debug Screen--Fault
Word4 bits 32-63 Status). This fault indicates the 24VDC power suppplies
are out of tolerance.
Action
1. Verify 24VDC power supply is no greater than 25 % out of tolerance
(that is, greater than 18VDC).
2. Check the physical condition and connection of the power supply wir‐
ing harness.
3. If the above steps do not resolve the issue, contact Siemens customer
service.
