4 Local Operation
4.1 Power LED
®
Once the TELSEC
MP2x is installed and powered, the system will start operating. Under normal
operation the green Power LED will flash at one second intervals to indicate the system is operating
properly. Occasionally there may be a pause in this operation if the system is saving data to flash
memory. If the LED is off for longer than one minute, then check the power connection and cycle
power to the unit. If the LED is constantly on longer than a minute, then cycle power to the system to
see if it goes back to normal operation of flashing the LED.
4.2 Relay Outputs
The normally open/normally closed terminations on the unit refer to when the output is de-energized.
Outputs can be operated by sending Modbus RTU write commands to turn on/off the outputs. See the
register map in section for further details.
