Probe Connections; Ph Probe; Orp Probe - Davey DPLGEU Instalación E Instrucciones De Funcionamiento

• When sliding the blanking plug into the housing, ensure that the blank is located ½ way into the probe
housing (refer Figure 4.15);
• Hand tighten the probe locking nut onto the probe housing, that will in turn tighten the washer onto the
o-ring (and create a seal). Repeat the process for all remaining probe blanks.
• The o-ring should not be lubricated when being fitted please ensure it is completely dry.

4.4. PROBE CONNECTIONS

4.4.1. pH probe

On the end of the pH probe lead is a locking BNC connector. The BNC connector for the pH probe needs
to fit into the back of the Davey Lifeguard controller, into the third BNC socket (refer Figure 4.15). The
connector is deliberately designed such that it fits only one way.

4.4.2. ORP probe

On the end of the ORP probe lead is a locking BNC connector. The BNC connector for the ORP probe needs to fit into the back of the Lifeguard controller, into the second BCN socket (refer Figure 4.16). The
connector is deliberately designed such that it fits only one way.
