Page 5: General Rules
GENERAL RULES Wa r n i n g s Read the warnings below carefully. They provide important information regarding safe installation, use and maintenance. Store this manual with the utmost care for future reference. The device complies with directive no. 2014/30/EU “electromagnetic compatibility” and no. 2014/35/EU “low voltage directive”. -
Page 6: Dispensing Harmful And/Or Toxic Liquids
G e n e r a l f e a t u r e s o f E Tw i n p u m p s ETwin is an easy to use device, consisting of a pair of metering pumps (electromagnetic or peristaltic) and electronics capable of measuring the chemical values of water in a swimming pool, such as pH, redox potential (mV) and chlorine concentration (in ppm). -
Page 7: Operating Principle Of Peristaltic Pumps
� Range of values: 0÷14 • Redox: -1000 ÷ +1400 mV • PPM: 0÷2, 0÷10, 0÷20, 0÷200 ppm • Temperature 0÷100 °C (PT100) • O p e r a t i n g p r i n c i p l e o f p e r i s t a l t i c p u m p s By peristalsis we mean the propulsive motion of automatic contractions inside a channel or pipe, from whence the term peristaltic action. -

Page 10: Installation
INSTALLATION Install the pump in a dry area away from heat sources at a maximum ambient temperature of 40 °C, while the minimum operating temperature depends on the liquid to be dosed which must always remain in the fluid state. Comply with standards in force in the different countries regarding the electrical installation (Fig. -

Page 14: Priming Functions
To facilitate pump priming, it is equipped with the PRIMING function. It is recommended to open the purge bypass on the pump bodies (for eTwin with electromagnetic hydraulics) during the priming operations. The air purge fitting must always be connected to the relative tube with return to the suction tank. - Page 15 CONSTANT: the pumps operate at a fixed frequency or speed until they reach the set-point value. • PROPORTIONAL: the time-pause intervals or the injection frequency decreases as the set point value approaches to limit • oscillations of the measurement INTERVAL: intervention value for the maximum PROPORTIONAL dosage •...

Page 16: Probes Connection
H p r o b e c o n n e c t i o n The following instructions apply to eTwin pH-Rx or pH-pH models where channel 1 is always allocated to the pH probe input. For Cl-pH instruments, on the other hand, the pH probe must be connected to the second channel. To get started, connect the probe to the instrument as indicated in Fig. -
Page 17: Rx Probe Connection
To allow the device to correctly detect the parameters of the water to be checked, the probes connected to it must be calibrated. Either electrodes made of glass or plastic can be used. The instructions for calibrating the probe apply to all eTwin device models and... -
Page 18: Ph Probe Calibration
p H p r o b e c a l i b r a t i o n The following steps show how to calibrate the pH probe. To perform the operations, you must have two vials of pH 7 and pH 9 buffer solutions of reference (the solutions are not included in the supply and can be requested separately). -
Page 19: Cl Probe Calibration
C l p r o b e c a l i b r a t i o n Before performing the calibration, you must modify the PPM VALUES SCALE parameter (see relative menu) based on the chlorine probe used. See the instructions attached to your probe for the preliminary connection and preparation operations of the sensor and relative maintenance. -

Page 23: Inputs
I n p u t s You may set the operating parameters of 4 different external inputs: • LEVEL 1 (5-6) • LEVEL 2 (7-8) • FLOW SENSOR (proximity) – (9-10) EXTERNAL COMMAND (11-12) • Refer to Fig. 8 for the connection to the respective terminals By DEFAULT, the proximity sensor and the external contact are set at NORMALLY OPEN. - Page 24 During the timer triggering period (ON) the display shows the measurements. Vice versa, when the device is off, again under timer, the display shows the date and time. If the timer is enabled by error, it is recommended to disable it or to reset the parameters.

Page 25: Alarms
A l a r m s The eTwin pump can monitor correct operation of the system and signal some alarm situations which can occur; to be more specific, the following alarms can be triggered: Level alarm • • Maximum value alarm •... - Page 26 To eliminate the ALARM, press OK and then ESC (only if the values have returned within the non-alarm range). If the values are still within the alarm threshold, to enter the MENU, press OK (the instrument goes in PAUSE) and then press ESC for about 5 sec.

Page 27: Ma Output
m A o u t p u t The device is equipped with an analogue output in 4-20 mA current which can be associated to only one measuring channel chosen by the user (SeeFig. 8 - terminal board for the connection). The following procedure shows the different steps to carry out to set the parameters. -
Page 28: Activation Delay
A c t i v a t i o n d e l a y If intervention of the pumps needs to be delayed, a delay can be set in hh:mm. The maximum time interval that can be set is 03:00 hh. The activation delay can be enabled independently on pumps 1 and 2. -

Page 32: Intervention On Etwin Pumps In Case Of Failure
7) Repeat this operation with water; 8) Reconnect the pump to the plant. INTERVENTION ON ETWIN PUMPS IN CASE OF FAILURE M e c h a n i c a l f a i l u r e s Since the system is robust, actual mechanical failures do not occur. Liquid can at times leak from a loose fitting or tube clamping ring nut, or simply if the pinch tube bursts. -
