Page 4: Packing List
The EF315 controller is supplied complete with instruction manual. INTRODUCTION The EF315 controller has been specially designed for the analysis and control of the main parameters of pool water. Available as pH/RX version with inputs for pH and redox electrodes on BNC connectors, or as pH/CL version with inputs for pH electrode (BNC connector) and for chlorine cell (prewired input). -

TECHNICAL DATA Inputs Specifications (Note: Precision and repeatability data refer to the electronics) Range 0.00 … 14.00 pH; input impedance > 10^12 Ohm (precision better than ±0.02 pH, repeatability better than ± 0.01 pH) Range 0 … +1000 mV; input impedance > 10^12 Ohm (precision better than ±... -
Page 6: Notes And General Advices
NOTES AND GENERAL ADVICES 1) Install the unit (electronic device) as far as possible from heat source and humidity. 2) Once installation has been completed, close carefully the cable glands, the terminal block compartment and the cover, in order to prevent oxidations of the electronic boards. 3) If the unit cannot be switched on even if powered, check the fuse F1. -

Page 10: Start-Up
START-UP At start-up, the EF315 displays for a few seconds the software version and the output configurations, then checks the memory status and shows an error messages if stored data are not correct. Finally, enters the normal measuring mode by displaying readings and updating the control outputs and the relay status. -
Page 11: Configuration
CONFIGURATION The controller features two configuration levels, standard and advanced. The standard configuration is reserved for the end customer, which normally only needs to change the adjustment thresholds. The advanced configuration instead allows to change all parameters and is normally password-protected, as this could be dangerous in case of intervention by unskilled personnel. The procedure is however the same for both levels. -

You can rarely have an acid replenishment water, and therefore p=2 is set to 1 to alkalize. PARAMETER 03 THRESHOLD PUMP 1 (pH) Enter the pH value to be reached.
- Page 15 PARAMETER 07 OFF STATUS PUMP 1 (pH) The operation of pump P1 depends on measurement 1. However some conditions may happen that block the pump, as a measure out of range (UR/OR), start-up delay (P15), pressing the ON/OFF key, alarm for max dosing time (P06).
- Page 16 This parameter allows to configure the operating mode of the FLOW input, depending on the flow control or consent used. In particular: P20=0 EF315 unit enabled with input open (NO) P20=1 EF315 unit enabled with input closed (NC) Note: If a NPN micro-magnetic flow sensor is use, set P20=1.
- Page 17 FLOW RATE PUMP 1 / PUMP 2 (litres/h) EF315 is equipped with the litre-counter of injected product. The flow rate of dosing pumps (Pump 1 and Pump 2) depends on model and system back pressure, and therefore is a value to be set at installation.
- Page 18 The operator can set or modify these numbers (or messages) by connecting the EF315 control unit to a PC via a serial line and using a simple communication program (e.g. Sercom or Hyperterminal). Enter the desired values with the command “Tn=0123456789ABCDEF”, followed by “Enter”, where “n”...

ERRORS / ALARMS When an error or alarm occurs, the display shows the related warning message on the fourth line. If more than one error / alarm is active, is shown the sequence of all warning messages. If you have set the displaying of the telephone number (or message) when an error occurs (P33 ≠... -

(no automatic recognition). If the input value is not compatible with the required calibration, EF315 displays the message “Calibration Failed !”. Even if you try to calibrate the offset with an incompatible input value, the message “Calibration Failed !” will appear. -
Page 21: Orp (Redox) Calibration
ORP (Redox) Calibration Preparation: a) Check availability and expiration date of the calibration solution (e.g. 230 mV) b) Close the water flow to the sensors Calibration procedure: 1) Remove the electrode from its support, rinse it with distilled water, then dry it 2) Immerse the electrode into the calibration solution (e.g. -

If you try to calibrate the gain at a value too far from the limits, the instrument automatically discards the calibration and generate an error. The display shows the message “Calibration Failed !”. Check that all the required initial conditions are satisfied. Moreover: a) Cleanliness of the CLE12 cell (if cleaning is required, then make the cell work for about 8 hours before proceeding with a new calibration) b) Status of the electrolyte and membrane of the CAC (or CP) cell;... -
