Output functions
Analog output
(switchable)
·
Outputs a current (4 to 20 mA) or voltage (1 to 5 V) that is proportional to the incident light
intensity.
Select current or voltage output with the output selection switch.
Judgement output
·
ON when the incident light intensity is below the set threshold value.
·
OFF when the incident light intensity is above the set threshold value.
(Includes a short-circuit protection function.)
Answer-back output
·
A one pulse output (1 sec) is generated when remote teaching has been completed normally.
Input functions
Reset input
·
This trigger signal starts integration when the Unit is in integral mode and the processing
mode is set to “RUN”.
Remote teaching input
· When the Unit is in monitor mode or integral mode, teaching is performed when a pulse signal
is input here.
Threshold setting function (monitor
mode only)
·
The desired threshold value can be set by pressing the Up and Down buttons. (The digital
display will change in 1% increments when the value is set.)
Sensitivity setting function (monitor mode only)
Zero point setting
·
Sets the zero point reference when the UV light source is OFF.
After teaching, the digital display will read “0%”.
Sensitivity setting
·
Sets the initial sensitvity when the UV light source is ON.
After teaching, the digital display will read “100%”.
Max. sensitivity setting
·
Sets the sensor sensitivity to the maximum sensitivity.
Min. sensitivity setting
·
Sets the sensor sensitivity to the minimum sensitivity.
Light intensity monitor function (Part of
the current/voltage output switching
function.)
·
Displays the digital (%) value corresponding to the incident light intensity and outputs the
analog and judgement outputs.
Light intensity integral function (Part of
the current/voltage output switching
function.)
·
Calculates the light intensity integral value (I) from the incident light intensity (P) and time (T)
using the following equation: I = P
´
T.
Also outputs the integral’s analog output simultaneously and displays the digital (%) value.
(Output ON at 100%.)
