Features and Components

Full-Time Continuous Monitor

Figure 6. Full-Time Continuous Monitor features and 

components

A

A. Park Snap:

 Allows the operator to disconnect (and

park) a wrist strap when leaving the workstation, without

creating a false alarm. Touch the park snap or park

switch, and the monitor's audible alarm will disable for

approximately 8 seconds. Use this time to disconnect

the wrist cord from the wristband, and attach it to the

park snap or remove the banana plug from the jack.

Upon returning to the workstation and disconnecting

the wrist cord from the park snap, the operator has

approximately 8 seconds to reconnect the wrist cord to

a worn wristband before activating the alarm.

B. Monitored Operator Jack:

 Insert the single-wire

wrist cord here to monitor the operator's connection to

ground.

C. Operator LEDs:

 Illuminates green when the

operator is properly grounded. Illuminates solid red and

audible alarm sounds when the operator is not properly

grounded.

D. Mat LEDs:

 Illuminates green when the worksurface

is properly grounded. Illuminates red and audible alarm

sounds when the worksurface is not properly grounded.

E. Ground LEDs:

 Illuminates green when the AC outlet

is properly wired and its path to equipment ground via

the equipment ground conductor is intact. Illuminates

red and audible alarm sounds when the AC outlet is not

properly wired and its path to equipment ground via the

equipment ground conductor is broken.

F. Park Switch:

 Allows the operator to disconnect (and

park) a wrist strap when leaving the workstation, without

creating a false alarm. Touch the park snap or park

switch, and the monitor's audible alarm will disable for

approximately 8 seconds. Use this time to disconnect

the wrist cord from the wristband, and attach it to the

park snap or remove the banana plug from the jack.

Upon returning to the workstation and disconnecting

the wrist cord from the park snap, the operator has

approximately 8 seconds to reconnect the wrist cord

to a worn wristband before activating the alarm. The 8

second timer is indicated by the growing intensity of the

park switch's blue LED. The blue LED will pulse when

the operator jack is vacant to indicate standby mode.

G. Power Inlet:

 Connect the included power cord here.

H. Mat Monitor Screw Terminal:

 Verifies that the

worksurface's path-to-ground is less than 10 megohms.

Connect the white mat monitor cord here.

I. Set Switch:

 Toggles the monitor's settings for the

audible alarm and mat monitor circuit. 

Function

Procedure

Audible Alarm 

Volume

1. Push and release the switch to

monitor circuit is enabled. A

non-illuminated MAT LED

indicates that the mat monitor

circuit is disabled.

J. Relay Terminal:

 Integrates with electronic locks,

lights, buzzers, etc. See the "Relay Terminal" section for

more information.
