Cycle modes
Cycle modes are used to determine the start-up procedure for single
break and double break mode. The settings that are made will only be
valid in cycle mode. Cycle modes are set using the input parameter
STyp.
They differ only in the start-up and reset phase of the preset cycle mode,
i.e. the setting affects:
- PSS start-up
- Changing modes from “Aus” to “single break” or “double break” mode
- 0/1-pulse edge at
RUN in “single break” or “double break” mode
- Time exceeded in cycle time monitoring.
INFORMATION
When the operating mode is switched from “Aus” (Off) via “Guard only” to
“Single break” or “Double break”, a function test must be performed (when
SSeq = 0) or a reset must occur (when SSeq = 1).
• Input parameter STyp = 0
- “Single break” mode
The ESPE/AOPD is broken once. The initial stroke is triggered via the
reset button (input parameter
RSET).
- “Double break” mode
The ESPE/AOPD is broken twice. The initial stroke is triggered via the
reset button (input parameter
RSET).
• Input parameter STyp = 1
- “Single break” mode
The reset button (input parameter
RSET) must be operated before the
ESPE/AOPD is interrupted in order to activate cycle counting. The initial
stroke will occur immediately after the first time the ESPE/AOPD's
protected field is cleared.
- “Double break” mode
The reset button (input parameter RSET) must be operated before the
ESPE/AOPD is interrupted in order to activate cycle counting. The initial
stroke will occur immediately after the second time the ESPE/AOPD's
protected field is cleared.
Error messages
Any fault that is detected will be stored in the corresponding error data
word (
SSNR) of DB015 (1st data block), until the fault has been fully dealt
with.
