DETERMINING THE MINIMUM ACCESS CHAMBER DEPTH
The minimum access chamber depth, is calculated as follows:
1. To the chosen Standard Probe Length (“H”), add 450mm, this is the overall probe length, enter this in column “I”.
2. From the Overall Probe Length subtract dimension “B + C” (bottom of tank to top of probe flange); the result is the
minimum access chamber depth. Enter in column “J”.
3. Calculate the actual access chamber depth, Dimension “E” minus dimension “C” and enter in column “K”.
4. Calculate the probe clearance (“K” – “J”) and enter in column “L”.
IMPORTANT! Column “L” must be zero or a positive number.
If the result is a negative number contact your
Veeder–Root Account Administrator.
TLS-IB Location
The TLS-IB should be located on an inside wall of the forecourt building Be sure the console will be protected from
vibration, extremes in temperature and humidity, rain and other conditions that could cause equipment malfunction.
The equipment is designed to operate safely under the following range of conditions:
• Altitude up to 2000 m.
• Temperature range of 0 to 40°C.
• A maximum relative humidity of 95% RH (non-condensing) at temperatures up to 40°C.
• Main supply voltage fluctuations not exc/- 10%
• Pollution Degree Category 2 Installation Category II
IMPORTANT! The TLS-IB unit must be installed within the interior of buildings.This unit is not suitable for any
external location.
Ensure that the TLS-IB is located where neither it nor its associated cabling will be damaged by doors, furniture,
barrows, etc. Consider the ease of routing wiring, ducting and probe cables to the unit.
Overall dimensions and weight of the TLS-IB are: height - 163 mm, width - 188 mm, depth - 50 mm, weight - 1.8 kg.
