Reset circuit error
Wiring to reset input terminals
X1, X2 and X3 are different from
the initial status due to discon-
nection or shorting.
Check wring of reset input terminals X1, X2
and X3.
Power voltage error
Specified voltage is not supplied.
Check wiring, power voltage and power
capacity.
The safety input 1 / 2
mode error
Wired safety sensor (Light cur-
tain, scanner etc) is OFF.
Be sure the safety sensor is ON
Wired safety contact (emergency
etc.) is “Open”.
Use 2NC (Normal Close) contacts
Be sure 2NC (Normal Close) contacts are
“Close”
No wiring of the safety input ter-
minals SIN+, SIN1, SIN2, SIN-,
SI+, SO+, SO-, SI-. Or the wiring
is not perfectly completed..
Check wiring of safety input terminals SIN+,
SIN1, SIN2, SIN-, SI+, SO+, SO- and SI- and
perform correct wiring.
Effect due to noise
or failure of internal
circuit
Influenced from noise etc.
Internal circuit is failed.
Check noise environment around this device.
If correct performance cannot be obtained,
contact us.
<OSSD output indicator dose not blink>
Cause
Remedy
Wired sensor is OFF
Be sure detecting output indicators (green) of sensor
connected are all light up. Clean up liquid on sensor.
Setting of control output polarity selection switch and
output polarity of sensor are not matched
Match the control output 1 / 2 (OSSD 1 / 2) and output
polarity of sensor
Connected sensor is broken
Replace the sensor.
