Gateway EC220
The unit is preconfigured, and the accompanying description from
the manufacturer is normally not needed.
Login information and additional description of the cloud service is provided separately.
The Gateway EC220, item no. 416230, is shipped with documentation,
registration data, and an AC adapter.
Note that the Gateway module need not be installed immediately adjacent
to the Autodos M. It can be installed in a separate area with access to
mobile data coverage.
Note that this product is not IP rated. If it is to be installed in an engine
room in an exposed environment, it should be placed inside a cabinet
whose IP rating corresponds to what is required in that environment.
Safety
Before making any electrical connections or performing other work on the Autodos and/or the EC220, the unit must be
disconnected from electrical power.
Installation of the Gateway EC220
1. Install the EC220 on a solid support in an IP-rated area.
2. Connect the supplied antenna.
3. Disconnect the Autodos M from electrical power.
4. Connect a 5-lead cable (5 x min 0,25 mm2) between the EC220 and the Autodos per the connection diagram:
Tx - / Rx - (bridged)
Tx + / Rx + (bridged)
Tx + connects to A on the EC220
Tx – connects to B on the EC220
GND connects to COM on the EC220
Leave the strappings for Modbus addressing in position.
Standby inputs 18 and 21 connect to relay outputs NO and COM, respectively,
on the EC220.
5. Connect the AC adapter’s single-wire to the EC220:
(+ red) to +VDC
(- white) to GND
6.
Connect the AC adapter to 230V AC and start the Autodos M.
The display will initially show Modbus information, then revert to a countdown
from 60 seconds
