Both «LED» and «EK...» are positioned under the transparent button. Pressing this button you unlock the command and control device.
Possibility of two diagnostics functions:
1. Visual indication directly on the unlocking 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 indication:
During operation the command and control device phase is indicated on the unlocking button. The following table lists all colour sequences
and their meaning. To activate the diagnostics function hold the unlocking button down for at least 3 seconds. A quick red flashing light
indicates that the function is active (see data sheet 7614). Likewise, hold the unlocking button down for at least 3 seconds to deactivate
the function (the switching will be indicated with a flashing yellow light).
