700 P electronics module

Attention!
Adaption can take up to 13 hours, depending on the control loop.
During this time no errors should occur on the control loop (e.g.
filter backwashing, changes in the circulation or widely fluctuating
number of visitors).
Please note
The adaption procedure can be terminated at any time with
“CANCEL”. The previously set parameters remain unchanged.
Completing adaption without
errors
When the loop times (dead time Tu and rise time Ts) have been
completed without error, calculation of the control parameters Xp
and Tn commences. This is shown by “ADAPTION OK”. The cal-
culated parameters are entered in the menus. When adaption has
been concluded, the measuring amplifier adjusts with the newly
calculated control parameters and continues in the selected oper-
ating mode (e.g. automatic).
To monitor the determined loop times they are entered into the
"Tu" and "Ts" menus .
If any errors in the control loop do occur during adaption (e.g. filter
backwash or changes in the circulation speed), this may lead to
incorrect loop times, resulting in wrong control parameters being
determined.
Attention!
The remaining control parameters Ymin, Ymax and Tp are not in-
fluenced when adaption is performed. The control parameters Xp
and Tn are determined for Ymin = 0 % (no basic load) and Ymax
= 100 % (no dosing rate limitation). Depending on the system, if a
basic load Ymin or a dosing rate limitation Ymax is required, re-
member that the control range is restricted. There is then the risk
of excessive chlorination (Ymin too high) or inadequate chlorina-
tion (Ymax excessively limited).
Completing adaption with errors
If errors occur in the control loop during adaption (e.g. filter back-
washing, changes in the circulation or widely fluctuating number of
visitors to the pool) or if the reaction times of the control loop are
too long, adaption is interrupted.
Please note
If any of the error conditions described below occur, adaption is in-
terrupted. The measuring amplifier displays one fault message.
The "old" parameters Xp and Tn are not changed.
