•
GUAR:
Global input of the monitor sequence
GUAR = 0: controlled shutdown when AuSt = 1, safety
shutdown when
AuSt = 0
GUAR = 1: monitor sequence is inactive: no error is present
•
AirP:
Air pressure monitor
AirP = 1: minimum air pressure is present
AirP = 0: air pressure is below the minimum
•
CHAI:
Global input of the safety sequence
CHAI = 0: safety shutdown
CHAI = 1: the safety equence is inactive: no error is present
•
FLAs:
Global input of the flame signals
FLAs = 0: fault lock-out
FLAs = 1: flame signlas are fault-free
•
FTRY:
FTRY = M110.01 (RLO =1): single attemptat a restart after a
flame error in operation (only possible if AuSt = 1)
FTRY = M110.00 (RLO =0): no option for automatic restart, a
fault lock-out occurs.
•
RUN:
The output parameter
RUN from SB159 “Run” must be
supplied to this parameter, so information about the operating
status of the main flame can be obtained."
RUN = 1: operating position.
• D_C:
Contains the number of cycles for the delayed enable of
SB152 after the PSS has started-up. The delayed enable is
required so that the flame monitors can reach a defined
position without a fault lock-out occurring.
Example: If the minimum scan time is 50 ms and the delayed
enable 5 s, the parameter
D_C must be assigned KB100
•
AuSt:
Automatic start (reset) when the PSS starts up
AuSt = M110.01 (RLO =1): automatic start (without reset) is
required after a controlled shutdown
AuSt = M110.00 (RLO =0): no automatic start required after a
controlled shutdown
•
RSET:
Reset button (N/O)
