5 Wiring/Miscellaneous For TLS-IB Consoles W/RS-232 &
RS-485
This section applies only to TLS-IB consoles with the following Form Numbers:
846620-580, 846660-580, 846690-580 (RS-232/RS-485)
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), 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.
Connecting Probes to the TLS-IB
Connect the two color-coded/marked wires from each probe to the appropriate connectors (e.g., Probe 1) of the
Probe Terminal Block as shown in Figure 5-1.
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,
RESULTING IN SERIOUS INJURY OR DEATH.
For this system:
1. Comply with the latest National Electric Code, federal, state, and local
codes, and any other applicable safety codes. In addition, take necessary
precautions during installation, service, and repair to prevent personal
injury, property loss and equipment damage.
2. Refer servicing to trained and qualified personnel only.
3. Substitution of components may impair intrinsic safety.
4. Be sure AC power is “Off” before opening the TLS-IB cover and
connecting probe wires. Do not short any voltage across any barrier
terminal including probes.
