J INDICATORS
1. STABILITY Indicator (Green)
When this indicator is lit, the ultrasonic input into the Receiver is
sufficient, or i ts interruption i s small enough, to ensure the
smooth operation of the E4B. Do not operate the E4B when this
indicator is not lit.
2. SENSING Indi cator (Red)
When this indicator is lit, the Receiver has ultrasonic input.
J INDICATOR OF THROUGH-BEAM
EMITTER
1. Incident Indicator
Lit when ultrasonic signal detected.
To use this i ndicator of the Emitter as an SENSING indicator like
the i ndicator on the Recei ver, connect the black lead wires of the
Emitter and Receiver together.

Note: Be sure not to make mistakes in pol arity when connecting the above wi res. In other words, both brown lead wires must connect to
+VDC or 0 V and both blue l ead wires must connect to 0 V or +VDC . Otherwise, the indicator of the Emitter will be lit when the
ultrasonic beam is i nterrupted.
2. Power Indicator
Lit when the E4B i s turned ON .
If the above connections are not possible (e.g., the Receiver and
Emitter use different power supplies), this indicator will be used
as a pow er i ndicator.
