DESCRIPTION

The Essex 2402 Pump Status Module operates in the following manner:

Assuming the pump is in the off condition, the green OFF indicator is lit.  If the HAND-OFF-AUTO pushbuttons are indexed to AUTO, and an external contact closure occurs which enables the pump or motor to start, an amber CALL indicator will light.  Once the pump starts, an auxiliary contact on the motor starter pressure switch, flow switch, etc. sends a "report back" signal to the 2402 causing the red RUN light to come on and the green OFF indicator and amber CALL indicator to go out.

If the pump fails to start, or fails to stop within a 0.2 to 60 second field adjustable time, the red FAIL lamp will flash, indicating trouble and an optional external horn will sound.   Depressing the ALM/SIL button will silence the horn and cause the FAIL indicator to light steadily.

If the HAND-OFF-AUTO  pushbuttons are indexed to HAND, an amber CALL indicator will light and the unit will operate as described above.

Auxiliary contacts are included on the HAND-OFF-AUTO push buttons to provide remote monitoring of these switches, or to provide the capability for external interlocking.  Field selectable power up or control input timing is standard.  This provides staggered starting of unit after a power failure or delayed starting each time the unit is activated.  All indicators light for approximately 1 second on power up or can be checked at any time using ALM/SIL button.

All of the switches and indicators on the instrument face are sealed for ease of cleaning and the prevention of switch contamination  from grease, dirt,etc...Units are provided with a custom engraved label identifying the use of the Pump Status Module.
