Starting The Electrolyser - BWT EES Notice De Montage

STARTING THE ELECTROLYSER

Once the electrolyser is wired in, hydraulic connections have been made, the water parameters have been
adjusted and the salt and stabiliser have been completely dissolved, the device may be switched on.
Upon being energised, the message OFF is displayed on the LCD screen. Press the ON/OFF button (7).
If the flow of water past the flow sensor is adequate (> 5 m3/h), the message ON (EES) or AUTO (EES
Pro - indicating that production of Chlorine is controlled by the pH and Redox sensors) is displayed at the
bottom of the LCD screen: the device is able to produce Chlorine.
If the message STD-BY (stand-by) is shown, the filtration timer is not currently at a run cycle: check that
the timer is in Auto mode and wait for the next filtration cycle, or force filtration on by switching the timer
to the I position.
If the timer triggers the filtration pump to run, but the water flow rate is too low (< 3 m3) or there is no flow,
the message NO FLOW is displayed. Check the following:
• the filtration pump is running
• the pump is properly primed
• the pump is rotating in the correct direction (in the case of a 3 phase pump)
• The valves on the by-pass loop are correctly adjusted: the central valve is sufficiently closed and the 2
valves upstream and downstream of the EES electrolyser are sufficiently open;
• water is flowing in the correct direction past the flow sensor, and the flow sensor has not been mounted
upside down.
• the flow sensor is correctly connected to the EES control panel
• Disconnect the flow sensor and using an ohmmeter check the continuity of the 2 connector contacts while
water is circulating.
When production is possible (ON for EES, AUTO for EES Pro), the device begins by measuring water
salinity, this value is displayed 1 minute after the device starts up. After this delay, if the salt concentration
is within acceptable limits, the production of Chlorine begins and gradually increases. Upon reaching the
required level, the bar under Output % stops blinking and disappears.
