Alarm Horn. The alarm horn alerts the operator or other attendants that a shutdown or warning condition exists. See Section 1.3, Controller Logic Specifications, for conditions. Place the generator set master switch in the AUTO position before silencing the alarm horn. The alarm horn cannot be silenced unless the generator set master switch is in the AUTO position. See Section 2.3.7, Controller Reset Procedure.
Alarm (Horn) Off. The keypad switch silences the alarm horn at the operator’s discretion. Place the generator set master switch in the AUTO position before silencing the alarm horn. Restore alarm horn switches at all locations including those on remote annunciator and audiovisual alarm kits to the normal position after correcting the fault shutdown to avoid reactivating the alarm horn. See Section 2.3.7, Controller Reset Procedure.
AM/PM. This keypad switch provides time of day data entries when programming.
Emergency Stop. The operator-activated pushbutton immediately shuts down the generator set in emergency situations. Reset the emergency stop switch after shutdown by pulling the switch knob outward. Use the emergency stop switch for emergency shutdowns only. Use the generator set master switch for normal shutdowns.
Generator Set Master Switch (Run/Off-Reset/Auto). This switch resets the controller fault lamps and start/stops the generator set. Refer to Section 2.3.1, Starting, Section 2.3.2, Stopping, and Section 2.3.3, Emergency Stop Switch Reset Procedure.
The generator set master switch with the keyswitch option (Figure 1-7) is available to meet appropriate local code requirements. The key is removable in the AUTO position only.
