The 200-WS-21-A Dual Set Point Wind Alarm is a microprocessor-based wind alarm system. It sounds an alarm and controls the operation of two electrical relays whenever wind speed reaches either of two independently user selected limits. A liquid crystal display provides readout of the measured wind speed, maximum wind speed, and it is also used to display the menus for the user to select the alarm parameters.
Each of the two set point alarms controls a self-contained Form ``C`` electrical relay. These relays may be used to control small electrical devices or to control external power relays for high current or inductive loads. An audible alarm, which may be user silenced, is also included within the WS-21-A. To eliminate erratic or premature operation of controlled devices, the WS-21-A includes provision for setting a delay or confirmation interval prior to initiation of an alarm and also a delay time prior to negating an alarm. |
