3.4 Terminal Block (External Signals)
Description
In addition to the basic operations, the electrolysis
system has a several input-output signals, which
allow the connection of additional external controls.
These inputs are located on a terminal block at the
main board of the unit inside the power supply.
1. HMI
2. Jumpers configuration of polarity switching
frequency
3. Cell electrodes
4. Cell auxiliary electrode (gas)
5. SMC power pack
6. Input 110-230VAC
7. RS-485 port
8. Pool cover input (dry-contact)
9. Flowswitch input (dry-contact)
10. External chlorine controller input (dry-contact)

3.5 Polarity Switching Configuration
The polarity switching frequency is configuring
using jumpers located at HMI on the backside of
powerpack front panel. Factory settings is 2 hours
(2h/2h).
2h/2h
3h/3h
4h/4h
7h/7h

3.6 Communication Port (RS-485)
The device has included on the board terminals
for Modbus connection. With the Modbus protocol
table you will be able to view and change different
values of the device. This device is compatible with
