3 Vac System Field Wiring - TLS-350/350R Consoles
Connecting Vac Sensor to TLS-350/350R Console
1. Connect each Vac Sensor/Vac Float pair and the Vac Sensor/ Tank Interstitial Float pair cables to either a
Smart Sensor with Pressure Sensor module or a Smart Sensor Interface module as shown in Figure 3-1. Note:
at least one Smart Sensor with Pressure Sensor module must be installed in the console for proper Vac Sensor
operation.
2. System programming of the Vacuum Sensors is performed following instructions in the TLS-3XX Setup Manual.
Figure 3-1.- Attaching Vac Sensors To Smart Sensor With Pressure Sensor Module
Connecting Pump Control to TLS-350/350R Console
FOR SITES WITH PLLD OR WPLLD LEAK DETECTION
Pump control for Vac Sensors is shared with PLLD or WPLLD line leak detection. Connecting PLLD/WPLLD leak
detection as per the instructions provided with that equipment is all that is required.
FOR SITES WITHOUT PLLD OR WPLLD LEAK DETECTION
A Pump Sense module and a 4-Relay module are required in the TLS Console for Vac Sensor pump control.
Field Wiring:
• For module connections with Red Jacket pumps see Figure 3-2. For module connections with non-Red Jacket
pumps see Figure 3-3.
