1. Strategies Solutions Innovation GUARDIAN PLUS CM 1701 USER MANUAL DESCRIPTION This Guardian PLUS CM 1701 is a single person and workstation continuous monitor The first channel monitors the path of the ground to the operator wearing a single wire wrist strap The other channel monitors the path of the ground to the ESD work surface Table Mat When using the monitor any breaking of the path to earth electrical ground of operator wearing a wrist strap or breaking the path to earth electrical ground the work surface Table Mat would be known at once because of the blinking RED LED and piezo buzzer The operator or work surface Table Mat is always connected to ground automatically even when the on off switch is in the off state The Guardian Plus CM 1701 thus becomes a common point ground even when the CT 1701 is in the off state IMPORTANT Always connect the Guardian Plus CM 1701 to earth ground INSTALLATION 1 Connect this equipment to the earth electrical ground of the building This equipment comes with a grounding wire One end of the ground wire is connected to the back of the CM 1700 The other end is connected to the earth electrical ground FIGURE 1 Always check that the electrical ground is correctly attached 2 Connect the CM 1701 to the ESD work surface Table Mat by using a cord with banana plug Not provided See FIGURE 1 3 Connect the ESD work surface Table Mat to the earth electrical ground the m2. the resistance of the path Work surface Table Mat to ground is higher or lower than the preset value the green LED of its testing side will change from a green LED to a flashing red LED and buzzer alarm SPECIFICATION Power source 9V DC adaptor Preset impedance Operator The wrist strap person adjustment can be changed The monitor can be changed by turning the adjustment screw to another value FIGURE 2 depending on the weight and or height of the user Preset resistance Work surface Table Mat This is 10 Meg ohms This can be adjusted to a different value FIGURE 2 Merely turn the adjustment from 10Meg to 5 Meg or 11 5 Meg Ohm ADJUSTMENT Operator A 5 Meg Ohm original setting was used to set up and calibrate the CM 1702 In case the user has lost or wants to recalibrate the setting connect a Smeg ohm resistor between the ground and banana jack for wrist strap Then turn the calibration knob in Figure 2 until the LED JUST changes from flashing red LED to solid green LED to a flashing red LED Work surface Table Mat A 10 Meg Ohm original setting was used to calibrate the CM 17as example in case the user has lost on setting Firstly connect a 10 Meg Ohm resistor between the ground and banana jack for work surface then turn the knob in Figure 2 until the LED has JUST change from flashing red to green or green to flashing red TROUBLESHOOTING Operator The red LED is always flashing red with a buzzer ala
