The CAM is an attachment that can be mounted at the generator set or at a remote location. The CAM annunciates faults, alarms or other conditions. Customer supplied inputs give the CAM this information.
The CAM operates when the CAM is powered by a 24 DCV battery system or a 32 DCV battery system. The CAM is equipped with a horn, an alarm silence switch and a lamp test switch. 8 switched inputs are also provided for the customer to use.
Note: A basic version of the CAM also exists. The basic version does not have a horn, an alarm silence switch or a lamp test switch. The basic CAM should be used with an existing fully equipped CAM or an ALM.
Alarm Operation
A given switch input will correspond to 1 of 8 indicators on the face of the CAM. The indicators will FLASH at a rate of 2 hertz when the corresponding input is closed to the battery negative terminal. The red indicators are used to display shutdown conditions, and the amber indicators are used to display alarm conditions.
When an input that is corresponding to one of the red indicators is activated, the indicator will flash and the horn will sound. When the input is disconnected from the battery negative terminal, the horn will continue to sound and the red indicator will continue to flash until the alarm silence switch is pressed.
When an input that is corresponding to one of the amber indicators is activated, the indicator will flash but the horn does NOT sound. When the input is disconnected from the battery negative terminal, the amber indicator will turn off.
Alarm Silence Function
The alarm silence switch is activated by connecting the corresponding input to the battery negative terminal.
When an input is connected to the battery negative terminal, activating the alarm silence switch causes the horn to cease. The indicator stops flashing and the indicator changes to being ON continuously. The alarm silence function will be overridden if the following event occurs. The status of any of the eight switched inputs change. The change of status will cause additional inputs to be closed to the battery negative terminal.
The Alarm Silence Function will not be overridden if the change in status is the opening of any of the inputs from the battery negative terminal. The indicators will turn OFF when the corresponding input is disconnected from the battery negative terminal.
Lamp Test Function
Activating the "Lamp Test" switch results in sounding the horn and turning on all indicators continuously for 10 seconds or until the switch is deactivated. The "Lamp Test" input can be wired to the switch of another alarm module.
Customized Labeling
The condition that is being monitored by each indicator is determined by the customer. The 130-3326 Film provides a wide variety of labels in order to customize the CAM to an application.
