Flashing LEDs illuminating buttons in any color with a frequency of 1 Hz indicates that the
power supply is switched off.

Flashing red button illumination with a frequency of 1 Hz indicates that the power supply
is switched off due to fault in the power supply or overloading of secondary power
sources.

Flashing LEDs illumination button (yellow) with a frequency of 1 Hz indicates that the
power supply is turned off, but one of the input voltage (backup or primary) is absent.

Continuous illumination of LED buttons (any color) indicates that the power supply is
turned on.

Continuous illumination of LED button (yellow) indicates that the power supply is turned
on, but one of the input voltage (back-up or primary) is absent, when the power supply
switches from the back-up source short signals with a frequency of 1 Hz are generated.

Continuous illumination of LED buttons (green) indicates that the power supply is turned
on and all input voltages are connected (back-up or primary).
In all modes, connection or disconnection of any input voltage is indicated by the single sound
signal for 1 second.
Operating Mode Alarms of the Power Supply
Indication Mode UPES Power Supply
Intermittent green illumination of the
UPES power button UPES is not turned on, all input
voltages are connected
Intermittent yellow illumination of the
UPES power button UPES is not turned on
One of the 220V input voltages is
absent
Steady green illumination of the UPES
power button UPES is turned on.
Supply voltage, the primary and back-
up are connected and normal.
Output voltage of primary
transducers-OK.
Output voltage of secondary
transducers-OK.
Steady yellow illumination of the UPES
power button
Generation of short signals once a
second UPES is turned on.
Powered by redundant power supply
220V.
Steady yellow illumination of the UPES
power button
There are no sound signals UPES is turned on.
Powered from the main source
220V
The main and back-up supply in UPES has no commutation through switches, so the power
supply shall be connected to UPES through an external switching device.
The gas analyzer can also be connected with external devices with the cable for the industrial
interface RS-485, RS-422 (4 twisted pairs) cable with armor in the form of corrugated steel can
be used in hazardous areas.
