Electrical Connection - Culligan Gold Series Owner's Manual

• Slip the sensor probe lead or meter cable through the hole and toward the circuit board.
Note: The strain relief located on the back of the wire connection for the Aqua-Sensor
probe may have to be removed in order to fit it through the backplate. Replace the strain
relief if you need to remove it for assembly.
• Connect the lead to the circuit board. The Aqua-Sensor probe terminal is labeled "Aqua-Sensor"
while the Soft-Minder meter terminal is labeled "Flow Meter".
• Pull any excess cable wire back out of the enclosure, and route the wiring inside the enclosure to
avoid any interference with moving parts.
• Locate the strain relief bushing in the parts pack. Place it on the cable at the point of entry to the
rear of the timer plate and push it into the hole.
Note: The wire connectors must be connected to the circuit board properly. The wires must
exit the plug-in connector opposite of the raised white base of the circuit board connector.
Failure to properly connect any of the connectors will result in a malfunction of the circuit
board operation.

Electrical Connection

The power cord needs to be connected to the plug-in transformer. Figure 19 shows the cord
attachment to the transformer for non Aqua-Sensor models.
Note: Observe all state and local electrical codes.
The Aqua-Sensor probe (Figure 12) requires a 2.5 VAC power source. This source is provided via
two of the posts on the 24V/2.5V transformer. Two leads from the transformer must be wired to the
2.5 VAC terminal on the circuit board. The wire connector from the Aqua-Sensor probe is simply
plugged in the circuit board (Figure 13).
Caution! Failure to connect power to the correct terminals will damage the circuit board!
