Probe Wiring Precautions
To The Installer! You Must Read And Understand This Information. Reference manual number 577013-578 for
additional safety related information.
PROBE WIRING POSITIONS AND LABELING
In all cases, the devices wired to the TLS-IB input terminal blocks must be recorded to prevent improper
replacement during installation or service.
Wiring Assignments
Identify all probe wires according to their terminal block location using the self-adhesive numbering labels
furnished. Accurately record on the circuit directory label (top of I.S. compartment cover plate - see Figure 4-1),
the tank number of each probe
as you attach wires
to the probe input terminal block.
Once a device has been wired to certain terminals and the system has been programmed,
the wires from that device may not be relocated to other terminals without reprogramming
the system.
WARNING
The equipment is used in location where lethal voltages and explosive vapors
or flammable fuels may be present.
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY
PRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT,
