Product Dimensions：
Woodward’s ESSE Series are single channel (ESSE-1) or two channel (ESSE-2)
electronic speed switches with exceptional power transient protection. The units are
potted for protection against harsh environments and have proven to be reliable and
rugged as well as flexible and cost effective.
In generator set applications, the ESSE Series can be used for crank (starter motor)
disconnect or overspeed protection, or for underspeed and overspeed warnings. In
fact, most speed-related switching functions on diesel and gas engines and other
rotating machinery can be accommodated by ESSE speed switches.
The speed switches can receive signal input from a magnetic pickup, alternator,
ignition coil, or Woodward’s Mini-Gen signal generator.
Both ESSE-1 and ESSE-2 offer four reset options for resetting the speed switch.
Electrical Latch Option -The switch (after the set point has been reached) will close
and remain closed even if the input signal frequency has been lowered to 0 Hertz.
The only way to reset the unit is to remove power. Manual Reset Option – By
depressing the ESSE’s reset button, the unit will be reset. Automatic Reset Option –
The switch will automatically reset if the frequency of the input signal is lowered to
85 ± 5%. The automatic and latch options are field selectable. Adjustable (automatic)
Reset Option – The switch will automatically reset at the frequency determined by the
setting of the supplied reset pot. By adjusting the pot, the reset can be selected
anywhere between 25% and 95%.
In addition to their standard features, ESSE speed switches provide options on the
input voltage range of operation, setpoint range, reset of tripped setpoint switches,
reverse relay logic control, and ignition signal input.
