Version pH/Chlorine
Front view:
• POWER: power cable (prewired)
• OUT1: driving output for pump 1 (pH control)
• OUT2: driving output for pump 2 (chlorine control)
• pH: BNC connector for pH electrode
• CL: input for chlorine cell
• PT100: input for Pt100 sensor
To access the terminal blocks, remove the compartment cover. The electronic board is equipped with
removable terminal blocks, as indicated here below.
- Terminals 1,2,3 (Earth, Neutral, Phase): power supply (standard 230V~); exchanging neutral and
phase does not affect the device operation
- Terminals 4,5,6 (Earth, Phase, Neutral): output for pump 1 (pH) – electromagnetic or peristaltic
Warning! This output can also be PFM type (pulse simulation with static relay)
- Terminals 7,8,9 (Earth, Phase, Neutral): output for pump 2 (chlorine) – electromagnetic or peristaltic
Warning! This output can also be PFM type (pulse simulation with static relay)
