High and High-High TOC levels (as set on the HMI) will raise alarms, but do not cause a system
shutdown. The High alarm merely serves as a warning, however, the High-High alarm overrides the
service demand signal and product water is returned to TK30-01 until the TOC falls within
acceptable limits.
Options are as follows
–
Option 81 Anatel TOC 600
Option 82 Sievers 500RL
Option 83 Thornton 5000
5.8 OUTLET VALVES
5.8.1 Option 90 Outlet 3-Way Valve
VA90-01 is a diverter valve to divert water to the product water tank when required and recycle it to
TK30-01 when not. The valve should be fitted as close as possible to the product water tank to
minimise the product water deadleg.
5.8.2 Option 91 Outlet Two 2-Way Valves
VA91-01 & VA91-02 are two 2-Way valves to divert water to the product water tank when required
and recycle to TK30-01 when not. The valves should be fitted as close as possible to the product
water tank to minimise product water deadleg.
5.8.3 Option 92 Outlet Three 2-Way Valves
VA92-01, VA92-02 & VA92-03 are three 2-Way valves to divert water to two product water tanks
when required and recycle to TK30-01 when not. The valves should be fitted as close as possible to
the product water tanks to minimise product water deadleg.
5.8.4 Product Water Return Line
During periods of extended flow to service the return line has no flow. To prevent stagnation, flow is
diverted through the return line on a regular basis as set by configurable timers, typically set for 1
minute in every 60 minutes (adjustable via HMI). It is thereby rinsed through with the full service flow
rate.
5.9 CLEANING IN PLACE (CIP) SYSTEM
TK30-01 and PU30-01 are used to clean the system in conjunction with flexible hoses and the
various CIP connections. The chemical cleaning requirements of various parts of the system are
different and it is therefore necessary to isolate certain components during cleaning and
preservation.
CIP is either a manual or semi-automatic operation, depending on which operation is chosen.
Manual CIP requires a written procedure to followed and equipment operated by the Force I/O
screen on the HMI.
Semi automatic CIP is prompted and run from the HMI, and requires less operator input.
