Section I Overview Introduction This document contains information on the operation, installation and maintenance of the DSB Series. This manual is an overview of the system and references the specific component manuals. User manuals are provided with the system for all configurable internal components. Description The DSB Series is a common cable termination point for bringing dual axis sensor cables into a switch box for routine data collection with portable data collectors. The DSB can have up to 8 dual axis sensors wired for data collection. DSB Model Selection The DSB Series Switch Box has options available to customize the system to your specific needs. Below is a guide to help select which DSB Series switch Box fits your specific requirements. 10/25/2013 2
Section II Installation Mounting Instructions The DSB Series Switch Box is contained within a fiberglass or stainless steel junction box enclosure, NEMA 4X rated. Mounting brackets are built into the enclosure for wall mounting. (Wall anchoring screws are not included). Note: If you have purchased a switch box without cable entries provided, you should add your own entry prior to mounting the switch box. Note: CTC does not recommend putting holes in the top of the switch boxes due to access and moisture concerns. Ensure the shield ground wire on the DSB Series Switch Boxes (Fiberglass Enclosures) is connected to earth ground. Note: The DSB Series switch boxes (Stainless Steel Enclosures) are internally grounded to the enclosure. Note: For DSB Series Switch Boxes (Fiberglass Enclosures), customer is required to supply wire from ground to shield ground lug, located on the outside of the enclosure. 10/25/2013 3
For DSB Series Switch Boxes (Stainless Steel Enclosures): When mounting the switch box to an earth grounded structure (such as an I-Beam), a shield ground wire is not necessary since the switch box is grounded internally to the enclosure. For DSB Series Switch Boxes (Stainless Steel Enclosures): When mounting the switch box to a non-grounded structure, ensure the shield ground wire or customer supplied ground wire is tied to a source of earth ground. If you are running conduit to your switch box, ensure the conduit cable entry enters from the bottom of the enclosure when mounted. Note: To ensure moisture will not flow into the switch box, a hole should be drilled at the lowest point in the conduit to provide drainage for any moisture. Cable Entry/Exit Figure 3 Earth Ground Cables enter and exit the enclosure through conduit fittings and/or cord grips on the bottom of the unit. All input wiring is routed through either a 1 conduit fitting or cord grips (1 per sensor). All output wiring is routed through either a 1 conduit fitting or cord grips (1 per sensor). 10/25/2013 4

Dual Vibration with 4-20mA output and Dynamic outputs: Socket A Positive (+ WHITE) connection for the dynamic acceleration, signal available on BNC A Socket B Positive (+ RED) PLC connection for the 4-20mA signal Socket C Negative (- BLACK) PLC connection for the dynamic acceleration and 4-20mA velocity output Socket GND Shield/Drain wire connection that is directed to Earth ground PLEASE NOTE: PLC connection is made on the continuous output connections of the supplied T plug connector as follows, PLC positive (+) connection on continuous output socket B and PLC negative (-) connection on continuous output socket C. Continuous Output Sensor Input Figure 8 T Plugs with Continuous Output 10/25/2013 7
Section III Operation Operating Procedure Once the sensors are attached correctly to the inputs, the unit is ready for use. Access the signal from the sensors through either the 2 pin or 3 pin connector or the BNC terminal s. 3 Pin Connector BNC Connectors Switch T Plug Figure 9 Module Layout 10/25/2013 8
Section IV Maintenance Once the system has been installed it requires minimal maintenance. Basic checks to ensure system integrity should be made periodically. Visual inspections should include examinations for the following: No visible electrical burns or smoke inside the enclosure Enclosure hinges are free from rust and securely latched No moisture or condensation build up inside the enclosure General There are no customer replaceable parts. The product has been designed for trouble-free service under normal operating conditions. Warranty If any CTC vibration analysis hardware product should ever fail, we will repair or replace it at no charge.
