CONTROL AND COMMAND EQUIPMENT LME...
OPERATION.
RED

The reset button «EK...» is the main element to access all diagnostics fun
-
ctions (activation and deactivation) and serves to unlock the command and
control device.
Both «LED» and «EK...» are positioned under the transparent button. Pressing this button, you reset the command and control equipment.
There are two diagnostics choices:
1. Visual indication directly on the reset button: operation and diagnostics of device status.
2. Diagnostics with interface: in this case the OCI400 connecting cable is necessary and it can be connected to a PC with ACS400 software, or
to gas analysers of different manufacturers.
VISUAL INDICATION.
During operation, the command and control equipment phase is indicated on the reset button. The table lists all colour sequences and their
meaning. To activate the diagnostics function, hold the reset button down for at least 3 seconds. A quick red flashing indicates that the function
is active. Likewise, hold the reset button down for at least 3 seconds to deactivate the function (the switching will be indicated with a flashing
yellow light).
