Dymax BlueWave® LED DX-1000 VisiCure® User Guide
Using the PLC Interface
The
BlueWave LED DX-1000 VisiCure
includes a 15-Pin D-Subminiature Connector for communication with a
PLC or similar process control equipment. The connector provides for input and output signals.

Pin Number
Name
Description
1
+24V input
If this input is not present, ignore all PLC inputs and allow the outputs to run
as usual.
2
Power supply and
signal common
Return for all signals on the on the PLC.
3
Sleep input
With 24V applied, disables all functions on the Front Panel, Footswitch, and
PLC Inputs. Shuts down the Fan completely after cooling the LED. Disables
the LED Displays except for the Scrolling Display Panel to indicate sleep
mode. If this signal is initiated during a cure cycle (duration >20 min.) the unit
will terminate the current cure cycle and go into sleep mode.
4
Interlock input
Allows operation of the unit in the PLC mode only if this signal is present. If a
safety switch is used then a failure (mode) in the switch or cables will
terminate the operation of the unit.
5
Activate input
This Pin will work as the Run or Footswitch activation at the current intensity
level (will be used for “simple” remote control of the unit when there is no
desire to vary intensity) and place the unit in manual mode. The PLC will
dictate cycle duration. The Cycle Time Display will indicate all dashes. When
this signal is terminated the unit will remain in manual mode.
6
Intensity input
This is a PWM input used to set the LED intensity and describe a running set
point. This input will work in conjunction with the Activate Input to enable
operation. The PWM base frequency shall be 1 KHz. The duty cycle will
dictate relative intensity.
7
Local disable input
When this Pin is asserted, the Footswitch and Run triggers will still be
operational, but the Front Panel Controls will be "locked out" from the user.
Activation can be accomplished but no adjustment to the mode of operation,
set point of the LED intensity, or the timer setting will be possible. This will also
prevent the ability to check system or LED operation hours.
8
Power on output
Asserted when the unit has correct AC voltage supplied and the internal
supplies are within limits.
9
LED powered
output
Asserted when the LED Power Supply is powered up, regardless of set point
(5-100% power). This activation can be either Footswitch, Front Panel
Button, or “Intensity In”.
NOTE: Verification of LED illumination should be made visually to ensure
proper operation.
10
Intensity output
This is a PWM-based signal to drive the LED. It is a confirmation of operation
for a given setting and as a relative indication of power level.
11
Fault output
This Pin is active when any critical fault conditions are met and the LED
operation is inhibited.
