Power-up Timed Inhibit (i.e., Lock- out)

Optional (see ordering option H); fac- tory set at 20 seconds (non-adjustable); invoked at initial power up or by inter- rupting power to the switch

Auto Reset

Configurable; switch can be configured with latching alarms requiring manual reset or non-latching alarms that auto- matically reset when vibration falls back below setpoint(s)

Remote Reset

Available via wiring terminals; short ter- minals to reset/acknowledge alarms.

Local Reset

Model 440: Optional via local pushbutton on switch housing (see ordering option F); remote reset not available when local reset specified. Local reset not compat- ible with hazardous area approvals.

Local Reset

Model 450: Local reset pushbutton not available.

Power Consumption

≤ 4 W

Light Emitting Diodes (LEDs)

One LED for each setpoint, illuminates immediately upon setpoint violation (i.e., not affected by alarm delay)

Buffered transducer output

Model 440: Standard option for BNC con- nector (see ordering option F); local BNC connector not compatible with hazardous area approvals; buffered output is unfil- tered 100 mV/g acceleration signal (not velocity signal).

Buffered transducer output

Model 450: Not available as standard; a special modification is available that provides a BNC connector inside* the housing; consult the factory.
* NOTE: Requires removal of enclosure lid for access.

Vibration Sensitive Axis

Perpendicular to mounting base; unit can be mounted in any orientation without change in sensitivity of this axis.

Self Test

One for each setpoint; allows functional testing of setpoint circuitry, time delay, and discrete output operation; permits online verification

Wiring Entries

Model 440: One (3/4” NPT) Model 450: Two (3/4” NPT)

Wiring Terminals

Accept up to 12 AWG wire; use yoke-type clamps; all wiring terminal blocks are cap- tive (non-removable)

Enclosure Rating

Enclosure Material

Model 440: Copper-free aluminum; light zinc chromate coating for corrosion re- sistance; epoxy powder finish inside and out; color: metallic blue

Enclosure Material

Temperature Limits

Units with internal accelerometer:

-30°C to +60°C (-20°F to +140°F)

Units with external sensor:

-40°C to +88°C (-40°F to +190°F)

Elevation Limit

2,000 m (6562 ft) above sea level
Max. operating temperature must be de- rated 2% for every 305m above 2000m

Elevation Limit

NOTE: Atmospheric pressure at elevations
≥ 2000m reduces heat dissipation and must be accounted for when determining max. operating temperature.
