Do not install and/or operate this safety product unless you have read and understand the safety
information contained in this manual.
1. Proper installation combined with operator training in the use, care, and maintenance of emergency warning devices are
essential to ensure the safety of you and those you are trying to protect.
2. Exercise caution when working with live electrical connections.
3. This product must be properly grounded. Inadequate grounding and/or shorting of electrical connections can cause high
current arcing, which can cause personal injury and/or severe vehicle damage, including re.
4. Proper placement and installation are vital to the performance of this warning device. Install this product so that output
performance of the system is maximized and the controls are placed within convenient reach of the operator so that s/he can
operate the system without losing eye contact with the roadway.
5. It is the responsibility of the vehicle operator to ensure during use that all features of this product work correctly. In use, the
vehicle operator should ensure the projection of the warning signal is not blocked by vehicle components (i.e., open trunks
or compartment doors), people, vehicles, or other obstructions.
6. The use of this or any other warning device does not ensure all drivers can or will observe or react to a warning signal.
Never take the right-of-way for granted. It is your responsibility to be sure you can proceed safely before entering an
intersection, driving against trafc, responding at a high rate of speed, walking on or around trafc lanes.
7. This equipment is intended for use by authorized personnel only. The user is responsible for understanding and obeying
all laws regarding warning signal devices. Therefore, the user should check all applicable city, state, and federal laws and
regulations. The manufacturer assumes no liability for any loss resulting from the use of this warning device.
8. This product contains high intensity LEDs, staring directly into these lights could result in temporary and/or permanent vision
impairment.
Unpacking:
Carefully remove the sensor and other components, and
check for damaged or missing parts (see the front cover of this
installation manual for a parts list and description). If missing or
defective parts are found, contact the transit company or ECCO
immediately.
Installation:
The magnets in the DS1500 sensor system may be mounted
using either the “tape-on” method (A), where the magnets are
taped directly onto the drive line, or the “bolt-on” method (B),
where the magnet assemblies are bolted onto the U-joint caps.
See Figure 2 on page 3.
(“A”) Tape-on Mounting:
1. Clean and degrease drive line in area where magnets
will be mounted. Steel wool and no-residue solvent
works well (brake cleaner, electrical contact cleaner,
etc.).
2. Find two opposite points on the drive line by using a
paper strip to divide the circumference of the drive shaft
in half. Wrap the paper strip tightly around the drive line
and cut off excess where the strip overlaps itself. Align
the ends of the strip and fold in half. Lay strip around
the drive line and make marks on the shaft next to the
ends of the strip and next to the fold point using a felt
tip marker.
3. Place the magnets 180° apart using the marks made in
step 2. A strip of masking or electrical tape temporarily
around the drive line can act as a guide to help position
the magnets exactly opposite each other.
4. Apply the supplied thermosetting tape over the magnets
as shown in Figure 1.
(“B”) Bolt-on Mounting:
1. Install the lock plate / magnet assemblies on opposite
caps of the U-joint.
