INSTALLATION Install the instrument in a dry place, away from heat sources at a maximum room temperature of 40°C. Comply with standards in force in the different countries regarding electrical installation (Fig. 2). If the power cord does not have a plug, the device must be connected to the mains by means of an omnipolar disconnecting switch with at least 3 mm between the contacts. - Page 11 Fig. 3 – Connection diagram TERMINAL BOARD “A” Relay 1 Setpoint 1 pH (o RX) ON-OFF / PWM output relay timed pulses Setpoint 2 pH (o RX) ON-OFF / PWM output relay timed pulses Relay 2 Relay 3 Setpoint 3 CL Chlorine ON-OFF / PWM output relay timed pulses Relay 4 ON-OFF ALARM relay output for external signalling device TERMINAL BOARD “B”...

The chlorine measurement CL works according to the corresponding values relating to the selected chlorine range indicating the value in Cl ppm. ADVANTAGES: the proportional function is more accurate than the ON-OFF mode. DISADVANTAGES: the user needs to be a professional in order to select the most accurate settings to assure the best results.
