INTRODUCTION
This guide describes the ADC DSX Bay Tracer Illuminator option used in large DSX-1 or
DSX-3 environments to enable technicians to locate far end LED tracer lamps more quickly.
The Bay Tracer Illuminator option consists of a stand-alone electronic sensor device that
mounts on the top of a DSX-1 or DSX-3 bay, and an inductive pick-up coil that mounts on
one or more –48 Vdc power input conductors feeding the bay fuse panel. Power to operate the
Bay Tracer Illuminator option is obtained from a branch of the same –48 Vdc central office
source that powers the components in the DSX-1 or DSX-3 bay.

1 PRODUCT DESCRIPTION
Electronic circuitry in the Bay Tracer sensor checks for a change in current on one or more
–48 Vdc power conductors on the DSX-1 or DSX-3 fuse panel caused by an individual jack
insertion on the far end bay and uses this change to activate an LED. The change in current is
detected by a clamp-on inductive pick-up coil encircling the –48 Vdc power conductor(s)
attached to the DSX fuse panel of the device being monitored. A two-conductor 8-foot (20.32
cm) trailing sensor cable attached to the inductive pick-up coil is used to transmit a signal to the
sensor. A customer supplied two-conductor (–48 Vdc and battery return) power cable is used to
transmit power from the fuse panel on the back of the DSX-1 or DSX-3 bay to the sensor.

3 INSTALLATION
The ADC Bay Tracer Electronic Sensor is designed to be installed on the top cross-member or
left/right vertical support flanges of the bay. The sensor and power cabling for the device must
be routed over the top of the bay as shown in Figure 1.

1. Attach the Bay Tracer Electronic Sensor Device mounting bracket to the top cross
member or vertical support flange of the DSX-1 or DSX-3 bay using two provided 12–
24 rack mounting-screws. See Figure 2.

2. Two sensor cabling options are provided for detecting a change in current on the –48 Vdc
power conductor(s) feeding the bay. If the bay is configured with DSX-only equipment
(option A), proceed to step 2a. If the bay is configured with a mix of DSX and non-DSX
equipment (option B), proceed to step 2b.

a. Unsnap the top bar of the inductive pick-up coil. Insert the main DSX-1 or DSX-3
–48 Vdc power conductor into the inductive pick-up coil as shown in Figure 3, making
sure that the label side of the coil faces toward the power source. Snap the top bar back
into place after inserting the power feed wire. Anchor the power conductor to the
inductive pick-up coil with a tie wrap or lacing cord in accordance with local practice.
b. Unsnap the top bar of the inductive pick-up coil. Insert the –48 Vdc conductors for the
DSX-only equipment into the inductive pick-up coil as shown in Figure 4, making sure
that the label side of the coil faces toward the power source. Snap the top bar back into
place after inserting the power feed wire(s). Anchor the power conductor(s) to the
inductive pick-up coil with a tie wrap or lacing cord in accordance with local practice.
Note: The battery return main conductor, or battery return distribution conductors are not
inserted into the coil and should be routed directly to the DSX-1 or DSX-3 fuse panel.

4. Attach the trailing wires from the inductive pickup coil to the ADC-provided sensor
connector making sure that the white conductor is routed to the negative (–) pin on the
SENSOR receptacle and the black conductor is routed to the positive (+) pin on the
receptacle. See Figure 5.
Caution: The sensor and power connectors are keyed identically and can be inserted into the
wrong receptacles on the Bay Tracer Electronic Sensor Device. Use care to avoid possible
damage to the sensor.

5. Attach the customer-supplied power feed wires for the electronic sensor device to an
unused –48 Vdc branch circuit on the DSX-1 or DSX-3 fuse panel as shown in Figures 3
and 4. Attach the opposite ends of these wires to the ADC-provided power connector on
the electronic sensor device making sure that the wire supplying –48 Vdc is routed to the
–48V pin on the POWER receptacle and the battery return wire is routed to the RET pin
on the receptacle. See Figure 5. A reverse blocking diode is incorporated into the electronic
sensor device to prevent damage from a power lead reversal.
Note: The fuse panel branch circuit should be fused at 0.5 A.

4 OPERATIONAL CONSIDERATIONS
The electronic sensor device LED may be falsely activated by external EMI emitted by power
drills, wire wrap guns, or other AC powered devices located within 12 inches of the inductive
pick-up coil. If such a condition occurs, the electronic sensor device automatically resets after
the change in current state and returns to a constant dc state.
5 TROUBLESHOOTING
The LED on the bay tracer electronic sensor device is designed to light whenever an individual
jack LED is activated on a DSX bay configured with the device. Table 2 provides a description
of common error conditions that may occur due to improper installation.
