4.4.3. Temperature sensor and TDS probe

On the end of the temperature sensor and TDS probe lead is a locking BNC connector and an RCA plug.
Both the BNC connector and the RCA plug needs to fit into the back of the Davey Lifeguard controller.
The BNC connector for the TDS probe needs to fit into the first socket (refer Figure 4.17) and the RCA
plug for the temperature sensor needs to plug into the RCA socket above it (refer Figure 4.18). The
connector is deliberately designed such that it fits only one way.
Figure 4.17
On the back of the controller at the base, use the cable retention slots for all cables & leads,
ref Figure 4.19.

4.5. THE DAVEY LIFEGUARD CONTROLLER

4.5.1. Powering the Davey Lifeguard controller

IMPORTANT: The Davey Lifeguard controller has been designed to constantly be
powered on and in System On.
On the back of the controller is an IEC input power socket.
• Connect the incoming power lead (supplied) into the IEC power socket on the rear of theDavey
Lifeguard controller (refer Figure 4.20).
• The other end of the incoming power lead should be wired into your 220-240VAC power supply.
Before powering up the Davey Lifeguard ensure:
• All probes are plugged in to Davey Lifeguard
• RJ45 communication cable and power lead connected
• pH, ORP and salt water calibration solutions are nearby
• Pump is not powered and pressure relieved
• Allow between 5 and 15 minutes for first time start-up
• Power is connected and on to EcoSalt2
