6.8 – Functionality of the regeneration cycle, flags 1CL and 2CL.
When
Aqua Timer Plus
is programmed to control
one duplex column
, it is possible to use a special distributor,
equipped with a stand-by position at the beginning of the regeneration.
The controller provides two flags, 1CL and 2CL , which must be programmed together to select the operative modality
of the regeneration cycle.
The flag 1CL selects the type of regeneration; standard , composed of 4 phases , or with stand-by , composed of 3
phases.
The flag 2CL selects the type of cam; standard or with stand-by .
Depending on how they are combined, the controller modifies the carrying out of the regeneration cycle, and in the
particular case of the duplex with mixed control modality (par. 6.2.6), the type of control on the start of the cycle also
changes.
The two flags can be composed thus:
Type 1CLx 2CLx Description
1 0 0 Standard regeneration – standard cam.
2 0 1 Standard regeneration – cam with stand-by.
1 0 Selection not valid. Works as Type 1.
3 1 1 Regeneration with stand-by – cam with stand-by.
The controller modifies the regeneration cycle as follows:
Type 1 The cycle is composed of 4 phases with movement times of 25 seconds each (Tab.25).
Type 2 The cycle is modified by the presence of the cam with stand-by. The position of stand-by is positioned at 25
seconds of rotation from the stroke end position and must be passed. The rotation time of the first phase must
therefore be of 50 seconds, 25 dedicated to reaching the position of stand-by and 25 to reach the position
expected for the first phase. The movement time between the second and third phases of the cycle is returned
to zero, losing the slow rinse after the aspiration. The rest of the cycle remains unchanged. (Tab. 26).
Type 3 As soon as the condition necessary for the start of the regeneration is in place, the controller puts the cam in
movement for 25 seconds, until the position of stand-by has been reached. This is the start point of the real
regeneration cycle, which can start immediately or at the programmed time depending on the operative
modality. The first phase of movement is of 25 seconds. The phase of movement between the second phase
and the third is annulled, thus losing the phase of slow rinse after the aspiration. (Tab. 27).
With reference to the description of the Type 3 , the start of the regeneration will be :
Immediate If the controller is set in
time or mixed mode and the time programmed for the start of the cycle has
arrived with the days run out or if it is a day programmed for the regeneration;
Immediate If the controller is set in volume mode with the flag 0HL programmed to 0 , that is the immediate start by
finished volume, and the volume has run out;
Deferred If the controller is set in
volume mode with the 0HL programmed to 1 , that is the deferred start to the
programmed time by finished volume, and the volume has run out;
Deferred If the controller is set in mixed mode and the regeneration has been activated by the finished volume.
