Console — Level Probe Cable Wiring Connections
Up to 4 Liquid Level Probes can be interfaced to the TS-1001, TS-750 or TS-504
console. Up to 8 Liquid Level Probes can be interfaced to the TS-2001 or TS-508
console. Three sets of terminals (+, –, and SHLD) are provided for each probe.
Remove the metal I.S. cover to gain access to these terminals. Remove 1-1/2” (38
mm) of jacket from each probe cable, and strip off 3/16” (5 mm) of insulation from
the end of each conductor. See Figure 7-2, 7-4 (a+b) and Figure 7-5 for Level
Probe Wiring.
In the console, it will be easier to wire from highest Tank (Probe) number to the
lowest Tank (Probe) number. For the TS-504, TS-750 and TS-508 consoles
start with the lowest Tank (Probe) and work up. Wire the three wires of the
probe cable to the PROBE interface terminal set (channel) as described below:
1) Connect the black wire to the minus – (BLK) terminal
2) Connect the red (or yellow) wire to the plus
+ (RED) terminal
3) Connect the cable shield to the SHLD terminal
Repeat this wiring scheme (from highest to lowest tank number) until all probes
are wired to the probe input channel terminals (+, –, and SHLD). A three tank
system will have 1 unused probe interface terminal-set. A probe can be wired to
any input probe channel and will operate normally after it is setup / programmed
correctly. In fact, a probe channel can be skipped (left unwired).
CAUTION Avoid wiring errors by maintaining consistent color codes when
making probe cable connections. Always use the Red (or yellow) wire for the +
signal. Always use the Black wire for – signal ground. And always use the bare
wire as the shield.
CAUTION
Make sure that the probe cable is wired correctly. Reversing the
plus and minus terminals can damage the I.S. circuits.
CAUTION Make sure that all conduits, conduit fittings, and junction box
fittings and hole plugs threads are waterproofed with pipe-dope. Wet wiring will
result in faulty operation.
CAUTION Make sure that all conduits and junction boxes are dry and
watertight.
ELECTRICAL DANGER Only one probe should be connected per
channel. Connecting multiple probes to a single cable or channel in the Tank
Sentinel console may damage to the unit and may create an explosion hazard,
and will result in improper system operation.
