Field Wiring
PROBE TO TLS-IB LOCATION
(LEV EL 1 INSTALLA TIONS ON LY )
Pull one two core, Probeflex cable from the TLS-IB location to each probe location.
Explosion could occur if other, non–intrinsically safe wires share TLS intrinsically safe wire conduits or wiring
troughs. Conduits and wiring troughs from probes and sensors to the console must not contain any other wires.
IMPORTANT! At least 2 metres of free cable must be lef t for connection at both the TL S-IB and the probe locations
.
Ensure that
all
cables are correctly identified. All probe field wiring
must
be legibly and permanently labelled with the
tank number.
IMPORTANT! Failure to correctly mark probe field wiring may lead to rework, delays in system installation and
additional charges.
MAXIMUM CABLE LENGTHS
A maximum of 305 metres of cable length per sensor or probe must be o b served.
DUCTING ENTRY TO TLS-IB LOCATION
Connection to the TLS-IB may only be made by a Veeder–Root authorised engineer.

Equipment Connected To The RS-232 Port
Any equipment such as a pump controller or point–of–sale terminal connected to the RS-232 port must meet the
following criteria:
• The equipment must have an EIA standard RS-232C or RS-232D communications protocol.
• The equipment must
NOT
be installed over or in a hazardous location.
The RS-232 Interface can be used for direct local attachment of terminals if the cable run is no mo re than 15 metres.
Veeder-Root do not guarantee proper equipment operation if RS-232 cable runs exceed 15 metres.
IMPORTANT!
RS-232 cable run s longer than 15 metres could result in data errors.
Run cable from the peripheral equipment location to the system console location. At least 1 metre of free cable must be
left for subsequent connection at both ends.
