Continuous Sensor Input Indication
(Red S IN LED continuously on):
1. Review the documentation that came with your sensor to learn the type
of output the sensor provides. Review the MX001 manual and find the
set up procedure that applies to your sensor. Check for proper
connection of the sensor to the MX001 sensor terminal block plus
proper positioning of the S set up jumper at J1. (Depends upon sensor
type in use.)
2. Check your sensor for output indication. Most sensors have a small
indicator on them or their controller that lights when the sensor output is
active. Make sure the sensor is not providing a continuous output.
3. Some sensors provide the option of output activation when they sense
or do not sense an object. Having the sensor set up to produce an
output when it does NOT sense an object will result in continuous
sensor output when the sensor is idle. Review the documentation that
came with your sensor to learn what type of output it provides and how
to configure it. The MX001 box expects to receive an active output
signal from the sensor (source voltage/current or switch closure) when
an object to be scanned is being sensed.
4. Check sensor gain/sensitivity adjustment for correctness. Most sensors
provide this adjustment to adapt to various sensing conditions. Check to
see if the gain/sensitivity is not set too low in beam break type sensors
or not set to high in diffuse proximity type sensors. Review the
documentation that came with your sensor to learn how to make this
adjustment correctly.
Continuous Sensor Alarm Indication
(Red A IN LED continuously on):
1. Review the documentation that came with your sensor to learn the type
of alarm output the sensor provides. Review the MX001 manual and
find the set up procedure that applies to your sensor. Check for proper
connection of the sensor alarm output to the MX001 sensor terminal
block plus proper positioning of the A Set Up jumper at J2. The MX001
expects to receive an active alarm output signal from the sensor (source
voltage/current or switch closure) when sensing conditions have
become marginal.
2. If the sensor in use provides an alarm output only when sensor
conditions are not marginal and cannot be configured otherwise,
contact Metrologic for special instructions on how to adapt to this type of
sensor.
