Input Logic
Channel 1/2/3/4 Exposure Control (CH1/2/3/4 Start)
Pulling CH1/2/3/4 pin to LOW (0) for 10mS or more will start irradiation on Wand
1/2/3/4, and follow their respective programmed power level and exposure time
settings for such wand on each channel.
Individual channels programmed to zero exposure time, will activate for the duration
that the associated channel pin is kept LOW.
Any additional pulse on CH1/2/3/4 will have no effect before any current exposure cycle
time is completed.
All Channel Exposure Control (ALL Start)
Pulling the ALL Pin to LOW (0) for 10 mS or more will start irradiation on all LED Heads.
They will run in accordance with the profiles configured on Channels 1, 2, 3, and 4.
Channels programmed to zero exposure time will activate for the duration that the ALL
Pin is kept at LOW.
Pulling the ALL Pin to LOW (0) for 10 ms or more will have no effect on any channel set
for zero exposure times. Channels will need to be individually activated.
PLC Detect
This pin acts as a detector for a PLC connector. When the pin is driven low, it represents
a connector present, the device will enter PLC mode and will ignore any front panel or
footswitch input.
