USER GUIDE TB-9026 Ground Man Plus Ground Monitor Made in the Operation and Maintenance United States of America Packaging 1 Ground Man Plus Ground Monitor 1 Monitor Ground Cord (Green and Yellow) 1 Power Adapter, 12VDC, with interchangeable plugs (North America, UK/Asia, Europe) (CTC334-WW only) 1 Certificate of Calibration Ground Impedance Monitor Continuously monitors for ground impedance on three separate channels that are connected to three process tools. The alarm level is set the same for all channels. Output Signal An output signal is available for connecting to the tools computer or PLC. The 5V signal is either logic 1 or 0 for Figure 1. Ground Man Plus Ground Monitor. indicating the monitored ground resistance/impedance conditions and for the wrist strap. Description Voltage on Person Wrist Strap Monitor Overview The Ground Man Plus Ground Monitor has a feature The SCS Ground Man Plus Ground Monitor can be that allows continuous monitoring of voltage on a person used at work areas or locations to monitor the ground through a dual conductor wrist band assembly. impedance of process tools including, but not limited to semiconductor, disk drive and flat panel environments. Ground impedance monitoring can be used for up to Performance three points for metal ground within a tool. The Ground Impedance Alarm Level Man Plus Ground Monitor can also be used to monitor The alarm level can be preset from 1 to 20 ohms (from the resistance to ground and voltage level on a person. 1 to 10 ohms in increments of 1 ohm and from 10 to 20 The unit incorporates green and red LEDs and audible ohms in increments of 2 ohms) by selecting through a alarms. combination of LED patterns indicated on the front on the unit. All three monitoring lines are set to the same The Ground Man Plus Ground Monitor is available in two selected impedance value. models: If the measured impedance on a line is lower than the Item Description setting, a green LED will remain illuminated for that CTC334-WW Ground Man Plus Ground Monitor, line(s). If the impedance is higher than the preset level, a with World Wide Power Adapter red LED and audible alarm are activated for that line(s). If the impedance level remains above the preset alarm CTC334-T Ground Man Plus Ground Monitor, level, the red LED and audible sound remains on. without Power Adapter The SCS Ground Man Plus Ground Monitor only SCS offers the following accessories for the Ground monitors proper connection to ground. The monitored Man Plus Ground Monitor: equipment must be properly ground by itself. A wire must be attached from the Ground Man Plus Ground Monitor Item Description (GND terminals) to approved ground points to monitor grounding of process tools correctly. 2368 Dual Conductor Fabric Wrist Band, Adjustable Output Signal Level The output connector provides a logic 1 (+5V) when all 2360 Dual Conductor Ground Cord, Coiled, 5ft. grounds are within limits and the unit is powered on. If any of the monitored grounds fail, a wrist strap fails, or 2370 Dual Conductor Ground Cord, Coiled, 10ft. power to the unit is lost, the output is logic 0 (0V). CTE701 Workstation Monitor Checker Person Voltage and Resistance Monitor The alarm level is monitored when a person is wearing a dual conductor wrist strap assembly and plugged into CTA251 Replacement Jack PCB, Ground Man Plus the front jack.

The alarm is also activated when the wrist band is worn too loosely and the loop resistance level is exceeded. The red LED indicates an over the resistance limit without a voltage being generated on the person at the same time. The green LED indicates proper connection of operator. A green LED plus blinking red LED will indicate if there is a body voltage generated operator may still be connected properly. The green LED is off when a dual Figure 2.

Enabling and Disabling Audible Alarm Installation The audible alarm can be enabled or disabled by Wire Attachment momentarily pressing a recessed miniature push-button The AC adapter should not be connected during the Set switch located on the back of the unit while the wire attachment process. Attach 18 AWG wires to the monitor is powered on. Use a pin to press the switch. unit as described below. Strip vinyl insulation at each end of the wires to approximately 1/3 in. (8 mm). Twist the stranded wire on each end before inserting wire into Environmental Conditions each connector location. This equipment has been tested and found to be safe to operate within these environmental conditions: Attach ground wire to the GND connector on the back of This is not a warranty of equipment performance within the unit.

Attach the unit using one of the following recommended methods: AC/DC Adapter Universal 100 - 240VAC, 0.5A, Screws ~50 - 60Hz SCS Dual Lock Fastener Output: 12VDC, 1.5A General Enabling or Disabling Monitoring of Dimensions (approx) 2.4 W x 0.85 H x 2.6 D (61 mm W x 21 mm H x 66 mm D) Ground Lines Weight (approx) 75g Sometimes not all three ground points in the tool need to be monitored. This procedure will set up the number of ground lines (G1, G2, G3) that will be used, so that there is no need to put jumpers or shunts on the unused ground monitoring inputs. The AC Adapter should not be plugged in at this moment. SCS - 926 JR Industrial Drive, Sanford, NC 27332 (919) 718-0000 Website: StaticControl.com 2015 DESCO INDUSTRIES, INC.
