SP ramp type
Whether or not the step operation is performed can be selected.
Additionally, the operation when the power is returned after a power cut
occurrence during step operation can also be selected.
• To make the step operation enabled, “2” or “3” is set.
• In case of set at “2”, the operation is stopped (READY mode) and returned to the
top of the step when the power is returned after the power cut occurs while the
step operation is running (RUN mode).
• In case of set at “3”, the operation is restarted from the step before a power cut
occurs when the power is returned after the power cut occurs while the step
operation is running (RUN mode). However, the SP and time before the power
cut cannot be returned completely and the step operation is restarted as described
in the following:
If the operation before the power cut is SOAK, the operation is restarted from
the beginning of the SOAK portion. If the operation before the power cut is
RAMP and the PV alarm (AL01/02) does not occur, the RAMP operation is
restarted from the SP same as PV. If the operation before the power cut is
RAMP and the PV alarm (AL01/02) occurs, the operation moved to the
SOAK portion next to the RAMP.
Handling Precautions
• The operation of this unit with the setting set at “3” (step operation,
operation is recovered when the power restarts) is different from that
of Yamatake’s digital programmable controller model DCP-series
(DCP31/32, DCP551/552). The DCP-series functions so that the SP,
RAMP, or SOAK elapse time immediately before the power cut
continues even after the power has been turned ON again. However,
this unit functions so that the operation is returned to the start point of
the RAMP or SOAK portions, which has been operated immediately
before the power cut has occurred.
• When the setting is set at “3” (step operation, operation is recovered
when the power restarts), it is also necessary to carefully check the
number of EEPROM (nonvolatile memory) writing cycles. When the
operation step proceeds in the RUN mode, the data is written into the
EEPROM (nonvolatile memory) every time the RAMP or SOAK is
changed. If the step operation is continued with a RAMP or SOAK
operation time of 10min or less, the erase/write cycles of EEPROM
may exceed its service life (approximately 100,000 cycles) within two
years. Therefore, do not attempt to operate the unit in such manner.
• When the SP ramp type is set at “standard” or “multi-ramp” (C31 = 0,
1) and the operation mode is the RUN mode, the operation mode is
automatically changed to the READY mode if the SP ramp type is
changed to “step operation” (C31 = 2, 3).
• When the step operation is set enabled, the LSP mode is fixed and
the LSP/RSP selection cannot be performed.
