5.0 Connecting an Operator to the 3M

(See Section 9 Accessories for selection of 3M

• Attach a 3M

™

snug fit, following the instructions received with the wrist band.

• Insert a Dual Conductor Ground Cord (longer plug end) into either one of

the input jacks located on the front of the Static Monitor 790. The wrist strap

monitoring function is activated during this step. The green lamp extinguishes

at this time and the corresponding red lamp will illuminate with an audible

alarm.

• Insert the other end of the ground cord (shorter plug end) into the wrist band

socket. The red lamp and the audible alarm should be extinguished at this

time.

Note: Following the attachment sequence above provides an operator(s) with a simple go-no-go

test of the wrist strap function every time they connect to the Static Monitor 790. A more detailed

verification procedure of the Static Monitor 790 system is outlined in Section 6.

Quick Review of Functions

• If the monitor's ground connection is maintained (including the chassis ground

connection when monitored) and the operator's voltage is held below the

pre-selected range, the cord, wrist band, and contact to the arm of the wearer

are all considered to be functioning correctly. At this time, the green lamp

illuminates on the front of the monitor.

• If an operator(s) develops a voltage that exceeds the pre-selected voltage

during normal work activities or the monitor loses its ground connection, the

green lamp extinguishes, and red lamp(s) will illuminate with a corresponding

audible alarm. This is an indication of an exceeded voltage condition on

the operator, due to poor electrical contact between the arm and band or

intermittent or broken ground cord.

• An operator's fault condition is easily identified by one of the two red lamps

next to each input jack. The flashing red lamp(s) identifies the operator that is

experiencing the fault condition. The red lamps and audible alarms flash and

beep at different rates to help identify the location of the fault.

Standby Jack 3057

™

Use of an optional Standby Jack 3057 at the workstation extends the life of the

monitor s input jacks. The operator disconnects the ground cord from the wrist

band and plugs into the Standby Jack 3057 that is mounted at the workstation.

Plugging into the Standby Jack 3057 prevents the Static Monitor 790 from

continuously alarming when disconnected from the wrist band.
