4.0 DescriptionOverviewThe 3M™ Ground Man Plus Workstation Monitor CTC334 can be used at work areas or locations to monitor the ground 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 three points for metal ground within a tool. The Ground Man Plus Workstation Monitor CTC334 can also be used to monitor the resistance to ground and voltage level on a person. The unit incorporates green and red LEDs and audible alarms.

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 tool’s computer or PLC. The 5V signal is either logic 1 or 0 for indicating the monitored ground resistance/impedance conditions and for the wrist strap.

Voltage on Person Wrist Strap Monitor The Ground Man Plus Workstation Monitor CTC334 has a feature that allows continuous monitoring of voltage on a person through a dual conductor wrist band assembly.

PerformanceImpedance Alarm Level The alarm level can be preset from 1 to 20 ohms (from 1 to 10 ohms in increments of 1 ohm and from 10 to 20 ohms in increments of 2 ohms) by selecting through a combination of LED patterns indicated on the front on the unit. All three monitoring lines are set to the same selected impedance value. If the measured impedance on a line is lower than the setting, a green LED will remain illuminated for that line(s). If the impedance is higher than the preset level, a red LED and audible alarm are activated for that line(s). If the impedance level remains above the preset alarm level, the red LED and audible sound remains on.

The 3M™ Ground Man Plus Workstation Monitor CTC334 only monitors proper connection to ground. The monitored equipment must be properly ground by itself. A wire must be attached from the Ground Man Plus Workstation Monitor CTC334 (GND terminals) to approved ground points to monitor grounding of process tools correctly.

Output Signal Level The output connector provides a logic 1 (+5V) when all grounds are within limits and the unit is powered on. If any of the monitored grounds fail, a wrist strap fails, or power to the unit is lost, the output is logic 0 (0V).

Person Voltage and Resistance MonitorThe alarm level is monitored when a person is wearing a dual conductor wrist strap assembly and plugged into the front jack. There is a short hold on the body voltage alarm so that it is not missed. The unit will respond to either positive or negative voltage. 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 conductor ground cord is not plugged into the jack.

10

Enabling and Disabling Audible AlarmThe audible alarm can be enabled or disabled by momentarily pressing a recessed miniature push-button Set switch located on the back of the unit while the monitor is powered on. Use a pin to press the switch.

5.0 InstallationWire AttachmentThe AC adapter should not be connected during the wire attachment process. Attach 18 AWG wires to the 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 each connector location.

Attach ground wire to the GND connector on the back of the unit. Insert a small blade screw driver into the orange slot above. Push inward and insert the stripped wire fully into the hole in the green connector. Hold wire fully in and release the screw driver to allow the wire to catch.

If you are planning to use the 3M™ Ground Man Plus Workstation Monitor CTC334 output to the tool, attach wire to the Out connector on back of unit. Insert the wire as described above.

Attach the impedance monitor wire(s) to the chosen ground line(s) G1, G2, G3 connector(s) on back of unit. Insert the wire as described above.

AC/DC Adapter ConnectionConnect the circular plug of the AC/DC Adapter into the power jack on the back of the unit.

MountingDetermine the mounting location of the Ground Man Plus Workstation Monitor CTC334. Attach the unit using one of the following recommended methods:• Screws• 3M™ Dual Lock™ Fastener

6.0 Enabling or Disabling Monitoring of Ground LinesSometimes 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.

Attach GND line to known good ground.Attach monitor line(s) (G1, G2, G3) to ground that has been determined to use. Do not plug any wires into those ground monitor inputs that will be unused.

Press and hold the Set button using a pin. While the button is pressed inward, plug in the AC Adapter and then release the Set button.

Wait then for approximately 30 seconds. The 3M™ Ground Man Plus Workstation Monitor CTC334s will beep during this time. After this time, the monitors will produce one beep and will automatically disable the lines to which nothing was connected. This procedure can be repeated whenever a change in the number of ground lines being monitored is required.

Enabling and Disabling Audible Alarm The audible alarm can be enabled or disabled by momentarily pressing a recessed miniature push button Set switch located on the back of the unit while the monitor is powered on. Use a paper clip to press the switch.

7.0 Setting Impedance Alarm LevelsBy default, the Ground Man Plus Workstation Monitor CTC334 factory set to a 10 ohms alarm level.

If this specification needs to be changed, the following procedure sets the impedance alarm level for all channels (G1, G2, G3).

Repeat the steps above in Section 4.0.

Right after the beeps stop; continue pressing the Set button until the impedance level is matched as shown in the table on the next page.

When the beeping stops, the four left-most LEDs (as shown in the photo on next page) allow for setting of resistance value. G1 & G2 red LEDs are upper location and G1 & G2 green LEDs are lower. Select the ground impedance value by pressing the Set button to advance the resistance limit. Turn the LEDs on or off as indicated in the table on the next page.

12

Not pressing the Set switch for about seven seconds after selecting causes the limit value to be saved and normal operation started.

8.0 Verification CheckVerification of G1, G2 and G3 monitoring.1. Prepare the 3M™ Workstation Monitor Checker CTE701A.2. Disconnect the wire connected to G1, G2 and G33. Connect the ground input of the checker to the ground connector of the 3M™

Ground Man Plus Workstation Monitor CTC334. Set the checker to a proper resistance alarm level (see the Workstation Monitor Checker CTE701A User’s Guide).

4. Connect the red wire tip of the checker to the device terminal (G1, G2 and G3)

5. Press the Metal Ground Fail button on the checker. The red LED of either G1, G2 or G3 should remain on.

6. Press the Metal Ground Pass button on the checker. The green LED of either G1,G2 or G3 should turn green.

7. Repeat these steps for all enabled ground monitoring inputs.

13

9.0 OperationsGround Impedance MonitorConnect the ground wire to an electrical known good ground point.

Connect the output wire to the tool, if you intend to use it; otherwise leave it open.

Connect the ground monitor inputs to identified locations in a process tool or several pieces of other equipment. Make sure to connect the monitoring inputs to different physical locations than those points used for their grounding.

Person Voltage and Resistance MonitorThis is a feature of the 3M™ Ground Man Plus Workstation Monitor CTC334. Plug the dual conductor ground cord of the wrist strap into the jack on the front of the unit. If the wrist strap is worn properly, a green LED will come on; otherwise the red LED will be on. In order to provide good ground connection, the wrist strap must be worn tightly and the green light on the Ground Man Plus Workstation Monitor CTC334 is an indication of that.

If, for some reason, while properly connected, the operator develops excessive body voltage (in excess of ± 2.5V in any polarity), the green LED may still be on, but the red LED will blink and the alarm sound will be on. No LED is on if a dual conductor ground cord is not plugged into the jack.
