1.
occurs ( due to the input 1 sensor break or input 1 current below 1mA
if 4-20 mA is selected or input 1 voltage below 0.25V if 1-5 V is selected ) if
PV1, P1-2 or P2-1 is selected for PVMD or PV1 is selected for SPMD.
2.
occurs ( due to the input 2 sensor break or input 2 current below 1mA
if 4-20 mA is selected or input 2 voltage below 0.25V if 1-5 V is selected ) if
PV2, P1-2 or P2-1 is selected for PVMD or PV2 is selected for SPMD.

Output 1 Failure Transfer, if activated, will perform :
1. If output 1 is configured as proportional control ( PB1 = 0 ), and BPLS is
selected for O1FT, then output 1 will perform bumpless transfer. Thereafter
the previous averaging value of MV1 will be used for controlling output 1.
2. If output 1 is configured as proportional control ( PB1 = 0 ), and a value of
0 to 100.0 % is set for O1FT, then output 1 will perform failure transfer.
Thereafter the value of O1FT will be used for controlling output 1.
3. If output 1 is configured as ON-OFF control ( PB1 = 0 ), then output 1 will be
driven OFF if O1FN selects REVR and be driven ON if O1FN selects DIRT.

Exception:
If Loop Break (LB) alarm or sensor Break (SENB) alarm is
configured for A1FN, the alarm 1 will be switched to ON state independent
of the setting of A1FT. If Dwell Timer (TIMR) is configured for A1FN, the alarm 1
will not perform failure transfer.
