Level Probe Wiring
Level probes must be wired with special shielded twisted pair instrumentation
cable. Cable required for Liquid Level Probes is based on the length of
cable run from the probe to the Tank Sentinel console. Only use the types
cables listed in Table 1-1
WARNING Only use the cables specified in Table 1-1 and do not exceed the
recommended maximum lengths. Use of other cables, or exceeding maximum
cable lengths may result in faulty operation, can create an explosion hazard,
and WILL void the warranty.
Cable Color Code
Use the following color code for the level probe wiring:
RED or YELLOW WIRE = + (Signal)
BLACK WIRE = – (Signal Ground)
BARE = SHLD (Shield)
Label Cables
Label all probe cables within the weatherproof pull box, and at the console with
the Tank/Probe number.
Model TSP-LL2 Probe — Cable Wire Splicing
Splice the probe cables together at the weatherproof junction box located in the
manhole as shown in Figures 7-4a . Connect the following 4 wires together:
black from probe, shield (bare) from probe, black from cable, and shield (bare)
from cable. If a white wire is present on the probe cable cut it back. NOTE:
some probes do not have a white wire. Connect the red conductor in the probe
to the red (or yellow) conductor in the cable. Use the No-Strip Electrical
connectors supplied in the installation kit to make all connections.
CAUTION DO NOT USE WIRE NUTS TO MAKE PROBE CONNECTIONS.
Use the crimp splice connectors supplied in the TSP-K4A installation kit, or
equivalent, only. Failure to use the appropriate crimp-splice connectors will
result in faulty operation and will void the warranty.
