Digital Output - Fuji Electric ZSS-8 Series Instruction Manual

Follow the instructions to check if the digital output relays properly work, and/or if the wiring has been done
appropriately.
6.10.1 Checking the digital output by using the alarm
The terminal number and the initial setting of each relay are shown in parenthesis.
(1) Light intensity low (DO1, SPST-NO)
Remove the receiver box or the transmitter box to generate a "light intensity low" alarm. Do not look
into the transmitter box. Otherwise, it may cause serious damage to your retinae or cornea. The "light
intensity low" alarm starts after about a minute during operation and about six minutes right after the
start-up. After you check the alarm output, attach the receiver box or the transmitter box to the angle
adjustment unit where they were.
(2) Device failure (DO2, SPST-NO)
Turn off the power, and disconnect the cable between the receiver unit and the control unit. Turn on the
power again, and the "connection error" appears on the screen and a "device error" alarm is emitted.
After you check the alarm output, turn off the power, connect the cable, and turn on the power again.
(3) During hold / during calibration (DO3, SPST-NO)
Hold the output in reference to "6.4 Output hold". Check the output during hold / during calibration.
After checking it, release the hold.
(4) Overrange/underrange (DO4, SPST-NO)
Set the range limit so that the current measured value is beyond the upper or lower limit, in reference to
"6.3 Alarm setting". After you check that the overrange/underrange alarm is emitted, set the alarm to
OFF or change the setting to the appropriate one.
(5) Environmental error (DO5)
Edit the analog input setting to channel 1 or channel 2 while no sensor is connected to the AI terminal.
"AI Under", which means the analog input error, appears on the screen, and an environmental error
alarm is emitted.
(6) Power interruption (DO6, closed during power interruption)
De-energize the analyzer and check the output. In the default setting, the contact is closed when no
power is supplied, and opened when the power is supplied.
