Leak Detection Sensors
Up to 12 / 24 leak detection sensors can be wired to the TS-1001 / TS-2001
consoles at the I.S. Probe & Sensor PC Board. Three interface channel
terminals (PWR, IN, and GND) are provided for each sensor. See Figure 7-7
for typical sensor wiring to the TS-1001/TS-2001 console.
One or two optional TS-SEM (Sensor Expansion Modules) can be added
externally to any Tank Sentinel console to increase the total number of sensors
to by 8 or 16 sensors. See Figures 7-8a thru 7-8c for this interface.
The TS-SEM is not approved for use in European Union markets where
ATEX approved devices are required.
WARNING Wire only one leak detection sensor per channel. Sensor and
system damage and failure will occur if more than one sensor is wired to the
same input channel, which will result in creating a safety hazard where leaks
are not detected.
Before Installing Sensors
Read the detailed installation and testing instructions provided with each type of
Leak Detection Sensor, and the Setup Programming Guide. Also see the TS-SEM
Installation manual before you add this optional module.
All leak detection sensors are supplied with a 2 or 3 conductor cable, a 1/2 inch
NPT cable compression fitting, and wire crimp-splices.
Before Wiring Sensors
At the Electrical Power Panel, turn off all Circuit Breakers / power to the
Tank Sentinel console before wiring a sensor, or before adding an optional
TS-SEM Sensor Expansion Module. See Chapter 1 for the recommended cable
or wire types to use with Leak Detection Sensors.
Wiring Steps for Each Sensor
1) At the weatherproof junction box: crimp-splice the same colored wires together
(blk to blk, wht to wht, and red to red).
2) At the console: remove the jumper link that is installed between the IN and GND
terminals of the channel that you will be using. Only used sensor channels
must have this jumper link removed (unused channels should have the link
installed).
DO NOT Daisy-Chain ground wires ...run separate conductors / cable from the
sensor interface terminals to the sensor(s)
