ON-delay timer switch
Adjuster indicator

Operation indicator (Orange)
Operation mode switch (Note 1)
Notes: 1) The operation mode switch of the DC-voltage type is the
DIP switch. Refer to ' 8 OPERATION MODE SWITCH' for
details.
2) Incorporated on EQ-5 T only.
8 OPERATION MODE SWITCH
Multi-voltage type (L-ON / D-ON mode only)
Operation mode switch Description
Detection-ON mode is obtained when the
switch is turned fully clockwise.
Detection-OFF mode is obtained when the
switch is turned fully counterclockwise.
Note: Turn the operation mode switch gradually and lightly with the
attached screwdriver. If the distance adjuster is over turned or
pressed heavily, it may be damaged.

10 DISTANCE ADJUSTMENT
For DC-voltage type, be sure to set the BGS / FGS function
before distance adjustment. If the setting is done after the
distance adjustment, the sensing area is changed.

11 STABILITY INDICATOR
Since the EQ-500 series use a 2-segment photodi-
ode as its receiving element, and sensing is done
based on the difference in the incident beam angle
of the reflected beam from the sensing object, the
output and the operation indicator (orange) operate
according to the object distance.
Further, the stability indicator (green) shows the
margin to the setting distance.

12 TIMER FUNCTION (EQ-5 T only)
An OFF-delay timer, which is useful when the
response of the connected device is slow, etc., an
ON-delay timer, which is useful when the input
specifications of the connected device require a
signal of a fixed width, are possible with EQ-5 T.
The OFF-delay timer and the ON-delay timer can
be used at the same time.
For DC-voltage type, set the DIP switch for the
timer selecting to 'Timer ON' side.
