This logic is also controlled by the RST (Reset) touch switch, toggle switch OFF (LED off,
audible alarm off), ALM (LED and audible alarm on), LED (LED on, audible alarm off), and
rotary switch DLY (alarm time delay setting). The alarm may be automatically reset if the
automatic alarm reset jumper is in place. Alarm delay settings are shown in
Table 2-5 . After an
alarm condition occurs, the operator may reset the circuit by placing a finger on the RST (touch)
switch contacts.
