4.2 Cycle time calculation
The 600 series controller will automatically set the cycle time based on the program or so called
unit number selected when programming the system (see System selection [
→
Page35]). Make
sure the programmed unit# is corresponding to your actual system and valve configuration.
4.3 Salt amount definition
The salt amount is set in kilograms of salt use for each regeneration. This setting will greatly
influence the system. Make sure this setting is aligned with your actual system size and unit#
programmed.
4.4 Injector flow rates
The following graphs represent the injectors flow rate as a function of the inlet pressure for the
different injector sizes.
