Irradiation in PLC mode
When in PLC mode, an external PLC can control the unit. The PLC provides input signals to the BlueWave AX-550 LED Flood
System to control the on/off signals and intensity of the LEDs. The PLC can also monitor the status of the system by reading
output signals provided by the unit.

PLC Mode Screen States
PLC Screen Detailed Description:
1.
LED ON/OFF Input
:
The status of UV LED control input (PIN 6 in). The screen shows
TRUE
(
1a
) when the input is
connected to common to turn on the UV LED; and shows
FALSE
(
1b
) when the input is open and the UV LED should
be off. The minimum signal pulse width High or Low is 500ms.
2.
LED Inhibit:
The input status of
LED INHIBIT
(PIN 15 in ). Enables or prevents the UV irradiation, to allow irradiation,
the screen must display a FALSE state (
2a, 2b
). When irradiation is disabled a
TRUE
state will be seen. LED inhibit is
typically wired to the door of a
Light Shield
unit. When LED Inhibit line is not connected to common, an error warning
of
LED INHIBIT OPEN
will be seen.
3.
LED Activated
:
Displays the UV LEDs irradiation status as ON (
3.a
TRUE) or OFF (
3.b
FALSE).
4.
LED Intensity (%):
I
ndicates the light intensity percentage value (
4a, 4b)
for the next time when the UV LEDs will
operate, The value can be set by either
ANALOG INTENSITY
input (PIN3 in ) in PLC mode or the control panel in
Admin mode.
5.
LED Intensity Control
:
The status of
INTENSITY
source (PIN7 in). Displays whether the LED light Intensity is
controlled via PLC’s
ANALOG INTENSITY
pin.
PLC
(
5.a
) or whether the last power value set on the control panel
PANEL.
If the Intensity is set by the ANALOG INTENSITY input, the intensity value will be locked when the LED is
activated. The LED Intensity setting can change according the ANALOG INTENSITY input but will take affect
only at the time that the LED become Activated.
6.
Master Interlock
:
The input status of the MASTER INTERLOCK (PIN5 in) is shown as
FALSE
(6a, 6b) if the pin
connected to common and shown as
TRUE
if the pin is open. The
TRUE
input will disable the UV operation, and an
error warning
MASTER INTERLOCK OPEN
will be shown on the bottom of the screen. For normal operation, the
status should be FALSE, ie, the pin should be connected to common.
