RTMS Echo User Guide
The following information on power, cabling, communications and placement
should be taken into consideration prior to installing the RTMS Echo.
Please review the following information before installation.
•
Read all instructions before using.
•
Heed all warnings in these instructions.
•
Save these instructions for future reference.
•
RTMS Echo units must be installed and adjusted in accordance with
the installation instructions contained in this manual.
•
Use the RTMS Echo only for its intended purposes as described in this
manual. Changes or modifications not expressly approved by the
manufacturer could void the user's authority to operate the equipment.
•
Consult Technical Support before using the RTMS Echo or other
RTMS Echo-related products for any purpose not expressly described
in this manual or any other RTMS Echo product manual. Do not use
the RTMS Echo to control or operate a gate-opening mechanism. Use
of the RTMS Echo for any unauthorized purpose may cause injury to
personnel or damage to equipment.
•
For optimal accuracy, it is strongly recommended that only trained
personnel survey the sites and install all RTMS Echo-related products.
•
For more information about our installation, surveying, and training
programs, contact your RTMS Echo sales representative.
The RTMS Echo is a constant power device that requires in its basic
configuration a maximum of 8 watts of power. Electrical power has two
components, voltage and current; both must be available in the correct ranges
to operate the RTMS Echo. The voltage must be between 12 and 24 volts DC
with the voltage level read at the RTMS Echo. Voltages below 12 volts will be
insufficient to power the RTMS Echo. Voltages above 30 volts could cause
damage to the sensor. Losses in the cable must be addressed in setting the
voltage to be supplied to the unit.
Current in sufficient quantity must be available: at 12 volts, the RTMS Echo will
draw roughly 660 mA of current; at 24 volts roughly 330 mA. Using an adaptor
that provides 12 volts and 100 mA of current means that the total power to the
RTMS Echo will be 12*0.1 = 1.2 watts, or roughly 15% of the power needed to
turn on the RTMS Echo.
