Low Power RemoteLog Special Features

Continuous RTU Operation

The Low Power RemoteLog runs on only a few milliamps of current, which enables it to run continuously without burdening its power source. (In other words, it does not go into a sleep mode that would prevent it from performing any of its functions.) Typical operation is to configure the Low Power RemoteLog to count pulses and watch for alarm conditions, and report to the master any exception conditions. Datalog records in a RemoteLog are stored in Flash memory, which retains data without the use of a battery. For lowest power operation, please refer to the topics below.

Reduced LED Power Draw

A special feature allows the status LEDs to be run in ‘dark mode" when an operator is not present to view them. The fourth discrete input (address X3) can be used to turn on (Enable LEDs) or turn off (Disable LEDs) when this input is On (power applied). This input can be connected to a door switch on the RTU enclosure or any other applicable signal. Select one of these modes as a "Special Feature" of input X3.

Note: This feature only works on the Low Power RemoteLog model.

Modem Sleep Mode Output

An external modem can be powered down until a report needs to be sent. Connect a power relay to the RemoteLog’s alarm output (D0). In the I/O Tool Kit configuration, select the "Modem Sleep Mode" special feature for this output. This output will come on five seconds before the RemoteLog sends any data in any reporting operation.

Note: This mode cannot be used if the RemoteLog will be polled as a slave because the modem will be disabled at most times.
