FC Probe/Pressure Sensor Wiring to TLS-450PLUS
Probe and Sensor Wiring Precautions
IMPORTANT - You must read and understand this information prior to wiring devices to console.
During programming, the devices wired to each connector are identified and
stored in system memory. If a device is later removed and reconnected to a
different set of connectors, the system will not properly recognize the data
being received. Once a device has been wired to certain connectors on a
USM or I/O Module and the system has been programmed, the wires from
that device may not be relocated to other connectors without reprogramming
that device.
Only intrinsically-safe wiring can enter a USM module slot knockouts.
Try not to have too much wire in the console. Pull unneeded wire back into the wiring trough and loop it neatly.
1. Open both front doors of the console (see Figure
32).
2. For sensors and probes, terminate the ground shields to the ground lug on the module (the other end at the
probe or sensor is NOT grounded).
3. Write in the device name for each wire connection on the connector block in the module’s wiring label
attached to the inside of the door.
WARNING
FAILURE TO COMPLY WITH THE FOLLOWING WARNINGS AND SAFETY
PRECAUTIONS COULD CAUSE DAMAGE TO PROPERTY, ENVIRONMENT,
RESULTING IN SERIOUS INJURY OR DEATH.
The equipment is used in location where lethal voltages and explosive vapors
or flammable fuels may be present.
Care must be taken when installing, servicing or replacing parts in the system
or serious injury or death from explosion, fire or shock may occur.
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 console panel doors and
connecting device wiring. Do not short any voltage across any barrier
terminal including sensors or probes.
