HI 9913 amp HI 9935 In order to optimize the controlling process and reduce the amount of chemicals and fertilizers used it is recommended to use a proportional dosage appropriate for the system HI 9913 and HI 9935 allow m for a proportional band delta X AK of 0 to 2 0 pH They also ur NDS allow for of proportional band PROPORTIONAL SETTINGS of 0 to 2 0 mS cm and 0 to 400 ppm for conductivity EC and TDS respectively Each controller also provides for two independent time cycles from to 90 seconds The propor tional dosage is obtained by a bs persona iz ng current pulse PROPORTIONAL SETTINGS Whose height equals the pH or EC TDS proportional delta and the length corresponds to the selected time cycle The controller will enter the proportional dosage at the setpoint plus or minus the preselected delta It will then keep the dosing relay activated for a period proportional to the difference between the actual measurement less the setpoint over the cycle NOTE If the setting is left at 0 pH the controller will operate as an ON OFF control with no proportional dosage In this case the controller will operate with a 0 1 pH hysteresis Similarly if the setting is left at 0 mS cm or 0 ppm the controller will operate as an ON OFF control with no proportional dosage The hysteresis of such an ON OFF control will be 0 1 mS cm or 15 ppm respectively Do not set the time cycle to 0 This causes the relay to chatter a
