USER GUIDE TB-9035 Ground Master Equipment Ground Monitor Made in the Installation, Operation and Maintenance United States of America Features and Components Figure 1. SCS CTC065-5-WW Ground Master Equipment Ground Monitor Description The Ground Master Equipment Ground Monitor Figure 2. CTC065-5-WW features and components determines whether equipment is properly grounded, helping to ensure the ESD safety of a process. The Ground Master Equipment Ground Monitor is a comprehensive real-time ground monitor that checks the connection of equipment to grounds in accordance with the ANSI/ESDA S.20.20 standard. It also monitors the presence of electromagnetic interference (EMI) on ground, signaling a possible functionality problem, such as tool lockup, erratic behavior, parametric error and more. The Ground Master Equipment Ground Monitor is available in three models: Figure 3.

Mounting Power Jack for power adapter. Depending on the mounting option that you have ordered, the Ground Master Equipment Ground Monitor Output SCS Static Management Program comes with a bracket to mount it on a flat surface. An (SMP) hardware optional DIN bracket to mount it on a standard DIN rail is Ext. Pins are connected in parallel with available. the Output jack Connecting Reference Ground The Ground Master Equipment Ground Monitor must be connected to a proper facility ground using its GND Overview connection. This ground will serve as a reference. No The Ground Master Equipment Ground Monitor monitoring is possible without this connection. continually monitors the grounding status of equipment. Make sure that this reference ground is a true ground and It provides independent ground monitoring of up to eight is properly connected to both facility (power) ground and tools. Monitoring of ground connection is done according to ESD ground, should these be separate at your factory. to the ANSI/ESDA S.20.20 standard. Specific limits are Crimp an 18 AWG (1 mm diameter) wire to the supplied set to the customer requirements. If no requirements are ring terminal and connect it to the GND terminal of the specified, default ground impedance is set at the factory unit. Connect the other end of this wire to the proper to 10 ohms. facility ground. Minimize the length of this wire since In addition to monitoring the connection to the ground, the impedance of this wire will be a significant factor in the Ground Master Equipment Ground Monitor offers measuring ground impedance of all connections. Do not monitoring of electromagnetic interference (EMI) coil the extra length of this wire. voltage on the ground wires often present in a factory environment. Such interference causes problems with the operation of equipment. The Ground Master Equipment Ground Monitor provides indication and alarm of the status of each ground and local alarms. In addition, this monitor provides digital output to a facility monitoring or data acquisition system for monitoring. To extend monitoring by eight points, another Ground Master Equipment Ground Monitor can be connected to the extension port. Connected units provide one combined output to a Facility Monitoring System. Figure 4. Connecting to main ground.
