2.1 Safety First
Throughout these instructions, special emphasis is placed on good safety practices. The following graphics are used to highlight certain topics that require extra precaution.
DANGER
DANGER represents the most severe hazard alert. Extreme bodily harm or death will occur if these guidelines are not followed. Note the explanation of the hazard and instruction for avoiding it.
WARNING
WARNING alerts you to hazards that could result in severe injury or death. Note the explanation of the hazard and the instructions for avoiding it.
DSR 100 SERIES OPERATION SECTION 2
To uncrate the product, remove the crate’s top, front, and back. Remove the accessories located on the crate’s shelf, then remove the shelf and packing material. Use a fork lift or other suitable equipment to glide the system from the crate and offthepallet.Forkliftprovisionsareprovidedinthe base of the system to facilitate this removal procedure(seeFigure 2.1).
CAUTION
Figure 2.1 Provisions in Unit’s Base for Forklifts
CAUTION indicates hazards that could result in potential injury or equipment or property damage. Once again, note the explanation of the hazard and the instructions for avoiding it.
2.2 Unpacking and Installing
Your system will be delivered to the ship-to address enclosed in a wooden crate and transported on a special, shock-absorbing pallet. With the addition of packaging, the DSR 100-75 test system canweighmorethan400pounds(180kg)andthe DSR 100-155 test system can weigh more than 450pounds(230kg).Toavoidseriousinjuryand/ or product damage, use a heavy-duty lift or other suitable equipment to unpack and move the product to its place of installation.
CAUTION
Use caution when inserting the forklift tynes into the unit’s lifting base. Do not drag the tynes heavily against the bottom of the unit when entering or exiting the base. Keep the tynes level at all times while handling the unit.
The system has been tested and inspected for damage before leaving the factory. Carefully unpack and inspect the product for damage. Please note any damage for future reference and notify the shipping company immediately if damage is found. Also, please save the shipping crate and pallet as evidence of damage and/or for returning the product for repair.

CAUTION
DO NOT use the system’s wheels to transport the system over long distances. The system’s wheels should be used only for moving the system over a short distance to position it in its permanent location.
2.4 DSR 100 Series System Location
DSR 100 Series test systems are mounted on wheelstoallowrollingonaflat,smoothsurface. The system’s wheels should be used only for moving the system over a short distance to position the unit in its permanent location. DO NOT use the system’s wheels to move the system over long distances. To avoid possible tipping, always push the system from the front and avoid rough or pitted surfaces.
Figure 2.2 Clearance Recommendations for System Placement
Locate your system near a three-phase power
source. Allow enough clearance at the front and
backtoallowadequateairflowandhotairdischarge through the system’s rear. See Figure 2.2

To reset after an Over Temp fault has occurred, make sure the fans are runninginalloftheamplifiermodules,and then remove the input signal from the system. Allow the fans to run for about 5 to 15 minutes, and then push and hold theResetbuttonontheMasteramplifier module’s front panel until the Standby LEDturnsoff.ReleasetheResetbutton to return the system to Run mode.

5 Maintenance
Simple maintenance can be performed by the user to help keep the equipment operational. The following routine maintenance is designed to prevent problems before they occur. See the “Troubleshooting” section for recommendations for restoring the equipment to operation after an error condition has occurred.
Preventative maintenance is recommended after thefirst250hoursofoperation,andeverythree months or 250 hours thereafter. If the equipment environment is dirty or dusty, preventative maintenance should be performed more frequently.
The procedures outlined in this section are directed towards an experienced electronics technician; it assumes that the technician has knowledge of typical electronics safety and maintenance procedures.
1. Turncompletelydown(counter-clockwise)all levelcontrolsandturntheamplifiermodules OFF. Turn OFF the DSR 100 system and disconnect it from its power source.
2. Using a vacuum cleaner, vacuum the front ventilation grill and the back ventilation exit grill ofallamplifiermodules.

6 Troubleshooting
If the DSR 100 system is not operating correctly, review the topics below for help with troubleshooting the problem. If the condition or error you are experiencing is not listed below, please contact AE Techron Technical Support at 574-295-9495 for additional help.
PROBLEM: The system has no signal output.
A: Check to make sure signal input is being generated using the 3110A Standards Waveform Generator or a stand-alone signal generator.
To see if signal is being generated by the 3110A, access the 3110A SWG software, and check to make sure that output is enabled for the test sequence and that the “Segment Enabled” option is selected for all wave segments.
If using a stand-alone signal generator, check the BNC cable connecting from the signal generator to the AUX INPUT connector on the front panel of the DSRsystem.Makesuretheconnectionsatboth ends are secure.
