Integrating Monitoring with External Circuitry
All inputs and outputs from the PLC interface are opto-isolated. The digital outputs are implemented using NPN
logic. The equivalent circuit is shown in Figure 9 below.

Running an Exposure
Optionally, use the StepCure screen (refer to
Section 6.4,
“Defining Exposure Parameters”
) to override the default
action of the PLC Enable 1-4 signal described below.
All LEDs are in either count up or countdown mode:
If the arrow in the status bar is pointing up, the unit is in count up mode. The UV LED Head connected to channel 1-4
will be on for as long as the PLC Enable signal is held low or one of the other input control signals is toggled. Use
count up mode when using an external timer for control of the LX500.
If the arrow in the status bar is pointing down, the unit is in countdown mode. The UV LED Head connected to
channel 1-4 will be on for the duration of the set timer for that channel on the Main Control Panel screen.
Note:
Pulses must be longer than 10ms.

Using the Foot Pedal
The foot pedal does not disable the
Start/Stop
button and can be used simultaneously with the
Start/Stop
button on the front panel in any mode or setting. However, the
Start/Stop
button overrides all foot pedal
configurations.

Connect the foot pedal to the port that corresponds with the UV LED Head on the back of the Controller
(refer to
