Sensor Transmitter Installation (Wireless Systems)
The Apollo GEM transmitter is designed to attach to a standard DIN rail and so can be mounted
inside a (plastic) consumer unit if there is room. The unit is 2 modules wide.
Alternatively the transmitter can be wall mounted using the supplied bracket, or installed in a
mini DIN rail enclosure.
Power can be provided to the sensor transmitter by either plugging into a standard 13A power
outlet or wiring directly to a 6A MCB in the consumer unit.
Plug in the current sensor clamp cable to the 2 pin connector on the top of the sensor transmitter.
If required, the standard 3M current sensor clamp cable can be extended up to 50M.
Sensor Transmitter Initial Checks
After installation apply power to the sensor transmitter. On power up the orange LED should
light, followed by the Green LED and then both LEDS should go out . After start-up either the
green or orange LED should flash. If power is currently being imported the green LED will flash. If
power is currently being exported the orange LED will flash. The speed of flash will depend on
how much power is being imported or exported. The faster the flashing, the higher the power.
Verify that the sensor is correctly installed using the following procedure:
1.
Power on the sensor transmitter
2.
Turn off the main solar PV isolator (this ensures no power will be exported)
3.
Check that the green LED is flashing (power being imported)
If the green LED is flashing all is well and the solar PV isolator can be turned back on.
If the orange LED is flashing the sensor is installed facing the wrong way round.
If the sensor has been installed the wrong way round either re-clamp the sensor facing the other
way or reverse the two wires in the green plug at the top of the transmitter module.
