NOTE :
NOTE : The monitor functions regardless of mode settings, but
an alarm is not indicated when alarm LED is set to
OFF position.
Trouble alarm outputs to prevent failing to replace sensor head
unit which is set for aiming. Alarm stops when the sensor head
unit is replaced to alert position.
NOTE : The monitor functions regardless of mode settings but
an alarm is not indicated in case of setting alarm LED
at OFF position. When power voltage recovers to
normal level during the alarm status, trouble alarm
stops.
When power voltage of sensor drops down (approx. 8.5V DC or
less), trouble alarm outputs before sensor operation comes to be
unstable due to low voltage.
See troubleshooting and remedy table.
Built-in CPU automatically checks/monitors sensor unit function, regardless of mode settings except a part of features.
2 : Low voltage
3 : Failure to replace
TROUBLE ALARM
NOTE : The monitor functions regardless of mode settings but
an alarm is not indicated in case of setting alarm LED
at OFF position. When power is reset during the alarm
status, trouble alarm stops only for warming up time.
Trouble alarm outputs when inner circuit / wiring is damaged /
broken.
See 11, troubleshooting and remedy table.
This function checks / monitors sensor unit itself in accordance
with built-in program.
When trouble is found out as a result of the check / monitor,
alarm LED lights and an alarm signal also continuously
outputs.

Change alarm contact to N.O. when sensor is used for an
application except security purpose, such as light control.
When operation check shows you high sensitivity of sensor,
change setting of sensitivity with mode selector and re-check
operation. Four settings are available.
Make use of the slight motion detection (motion of hands or
body) at narrow range.
This mode is so sensible
to detect even a slight
motion that the
performance to
discriminate small
animals might be low.

SENSOR FUNCTIONS
Sensor operation can be adjusted to fit the environmentals /
applications with the built-in mode selector.
ALARM LED
The alarm LED will light up, synchronized with the alarm contact,
if you set the mode selector at ON.
This disables the alarm LED even
if an alarm is initiated.
Turn OFF alarm LED with the
mode selector after operation check
is completed.
ALARM MEMORY
When this setting is "ON".
Memory is always stored when
sensor is armed.
When an alarm has been activated,
the memory LED flashes for 3 min.
and then remains lit for 47 min. It
automatically reset and memory is
also canceled.
