– IF pH is within allowed range:
When pH value is within allowed range, water is mixed for the
"mix" time to ensure water remains within allowed range. If water
gets out of allowed range, control resumes injection.
If water is not within allowed pH range within 9 injections (default
value adjustable in service mode) an alarm is generated.
4.4 Review and Print
Specific Cycle Program
All cycle programs may be reviewed by accessing Cycle Review
mode when a cycle is not in progress. Cycle Review mode allows
user to review cycle phases and values programmed for specific
cycle selected.
1. Press REVIEW touch pad to access Cycle Review mode, and
review first phase of selected cycle.
2. Press left and right arrow touch pad to review the other treat-
ments of the cycle. Press
X to exit the Cycle Review mode.
To print cycle values select the cycle that should be printed and
press
PRINT touch pad.
4.5 Extend Cycle
Phase Time
Cycle phase times may be temporarily extended by pressing Extend
Phase touch pad while cycle is in progress. Temporarily extended
phase times apply only to immediate cycle selected. On completion
of cycle, phase times return to programmed setpoints.
After starting a cycle, programmed time for each phase may be tem-
porarily extended only when particular phase process is in opera-
tion.
To extend phase time, press EXTEND PHASE touch pad while
actual phase process (i.e., recirculating, exhausting) is in operation.
Each time touch pad is pressed, programmed time setpoint is added
to phase time remaining.
NOTE: Filling and draining functions are not affected by extend
phase feature. If EXTEND PHASE touch pad is pressed during these
functions, cycle continues as programmed.
4.6 Bypass Phase
A cycle phase may be bypassed only if Temperature Guarantee is
not selected.
If Temperature Guarantee is not selected, cycle phase may be
bypassed only while particular phase process is in operation.
Bypassed phases apply only to immediate cycle in progress.
To bypass a phase, press BYPASS touch pad while actual phase
process (i.e., recirculating, exhausting) is in operation.
Control aborts phase process in operation and automatically contin-
ues with next programmed function.
NOTE: Filling and draining functions cannot be bypassed.
