Both lockout reset button (EK) and signal lamp (LED) are located under the transparent cover of the lockout reset button.
There are 2 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 (see technical sheet 7614).
Visual diagnostics:
During operation, the command and control device phase is indicated on the reset button. The following 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 (see data sheet 7614). 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).
