Page 8: Password
Password At first start of the controller there is no password set. To set a new password with administrator privileges to enter the main menu by clicking on the icon, ,then select “Settings”, press the dial and select “PASSWORD”. Press the knob and insert a code of four numbers. -
Page 9: Main Menu
“Main Menu” list To grant access into “Main Menu” enter the passcode (as described in previous chapter). Once into “Main Menu” rotate the wheel to scroll through all the options available. Settings (see page 9) Flow (see page 20) General Options (see page 20) Reset Controller (restore all parameters) Out mA (see page 21) Standby (see page 21) -
Page 10: Settings / Measure" (Ja Cd)
“Settings / Measure” (JA CD / CDIND series only) According to connected probe the “K” factor can be selected between 1 - 10 - 001 - 01. “Automatic Range” let the controller automatically set the most suitable scale according to reading range or press the wheel to choose between Ohm - H3PO4 (see page 22 for more info). -
Page 11: On/Off" Mode
“ON/OFF” mode (e.g. conductivity) This working mode ca be set for OUT1 and OUT2 outputs. ON/OFF mode Set Conductivity value at 100uS ON and 90uS OFF. The difference between the two Conductivity values is called HYSTERESIS. Setpoint output will stay OFF until reading value will reach 100uS Setpoint output will stay ON until reading value will decrease to 90uS Conductivity pump will stay into its previous status into HYSTERESIS AREA... -
Page 12: Proportional" Mode
“PROPORTIONAL” mode (e.g. conductivity) This working mode ca be set for OUT1 and OUT2 outputs. Proportional mode set the controller to operate using a calculated percentage based on a 1000 seconds scale between two set values that enable or disable the Conductivity pump. To use this mode move cursor on “Working Mode”. Press the wheel and select it. -
Page 13: Pid
“PID”mode (e.g. conductivity, available on “PRO” models only) A proportional-integral-derivative controller (PID controller) is a control loop feedback mechanism (controller) widely used in industrial control systems. A PID controller calculates an error value as the difference between a measured process variable and a desired setpoint. -
Page 14: Calibration" Ja Cd Model
“CALIBRATION” (JA CD series) Conductivity calibration procedure involves a “SLOPE” value that requires a buffer solution having a value near the working range. Calibrate using plant’s temperature otherwise unattended results may occur. Verify probe selection into “SETTINGS”, “Measure” before to start calibration procedure. Then choose “CALIBRATION” then “CONDUCTIVITY” to begin calibration procedure. -
Page 15: Calibration" Ja Ph Model
“CALIBRATION” (JA PH series) Full pH calibration procedure involves two calibration points (Offset and Slope) and it requires two buffer solutions. Default buffer solutions are pH 4.00 and pH 7.00. pH reading value can be also compensated from “pH compensation” menu. Chose “Calibration” from main menu. Fast Calibration procedure involves one point calibration (choose value closest to real field application). -
Page 16: Calibration" Ja Rh Model
“CALIBRATION” (JA RH series) ORP calibration procedure involves probe’s selection with one point (P1) calibration. From “Menu Calibration” choose “ORP probe”. Choose between “FAST CALIBTRATION” (one buffer solution required) or “FULL CALIBRATION” (two buffers solutions required for better calibration accuracy) Note: This procedure assumes that instrument is correctly configured and a working ORP probe connected and installed on system. -
Page 17: Compensation" (Ja Cd Model)
“COMPENSATION” Conductivity measurements are temperature dependent. The degree to which temperature affects conductivity varies from solution to solution and can be calculated using the following formula: Gt = Gtcal {1 + a(T-Tcal)} where: Gt = conductivity at any temperature T in °C, Gtcal = conductivity at calibration temperature Tcal in °C, a = temperature coefficient of solution at Tcal in °C. -
Page 18: Calibration" (Ja Cl / Ja Temp Model)
“CALIBRATION” (JA CL series) Chlorine calibration procedure is based on installed chlorine probe and may involve one or two calibration points depending on probes’ model From main menu choose “Calibration”. Installed probe will be automatically detected and according to model a one or two points calibration will be enabled. Photometer Carbon Filter System Note: This procedure assumes that the CONTROLLER is correctly installed and configured, connected to a working... -
Page 19: Modbus
“MODBUS” (available on “PRO” models only) Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices. -
Page 20: Flow
“FLOW” Flow contact (see “SEPR” blocks on page 4) can be enabled to stop a dosing procedure using a N.O. contact mode (normally open) or N.C. contact mode (normally closed) when status on blocks changes. Rotate wheel to choose between: “DISABLE”, “REVERSE” (N.O. contact) or “DIRECT” (N.C. contact). Furthermore “Flow contact” can starts after a specified time when contact status changes. -
Page 21: Out Ma
“OUT mA” This menu allows to configure mA current output. Parameters to set are: MODE (selectable between 0-20 or 4-20 mA current output) Max mA: maximum probe’s reading value at 20 mA current Min mA: minimum probe’s reading value at 0 or 4 mA current Disable / Enable on alarm: enable or disable output on flow alarm “STANDBY”... -
