MAXIMATCX
Compact overfill detector
SAFETY INSTRUCTIONS
- Installation, commissioning and maintenance may only be performed by qualified personnel!
- Only connect the device to the voltage specified in the technical data or on the type plate!
- Disconnect the device from the power supply during installation/maintenance work!
- Only operate the device under the conditions defined in the operating instructions!
DESCRIPTION
The MAXIMATCX compact overfill detectors are level limit switches designed to prevent overfilling of tanks containing media hazardous to
water. When the probe is touched by an electrically conductive medium, the integrated electronics react and the permanent output signal is
interrupted.
This signal can be output by the plant control system as an acoustic or visual alarm signal and, if necessary, used for emergency shutdown of
the filling process.
APPLICATION
The level sensor is suitable for media whose impedance is <5kΩ or whose coupling capacitance to ground is >50pF.
The media must not form insulating or conductive deposits.

SIGNALING
LED (green) on the connection board (only for version with connection head):
Operation LED lights up
Alarm / Fault LED off
MAINTENANCE
When used as intended, the device is maintenance-free.
FUNCTION TEST: before installation / during commissioning / during revisions
Method 1
Measuring sensor
CE
The bucket is on the floor.
• Fill a bucket (plastic or metal) with the process medium or water (at least 5 liters)
and place it on the floor
• Immerse the sensor several times and remove it again!
• Check the switching state of the measuring circuit!
Method 2
Ground connection:
- Protective conductor
foundation earth electrode
- Metal railing
- Metal water pipe
- Metal support pillar
etc.
Cable/strand for grounding the medium
The bucket is not on the floor.
• Fill a bucket (plastic or metal) with the process medium or water (at least 5
liters)!
• Ground the filled medium with a cable or stranded wire!
• Or grab the bucket with your hand from the outside!
• If the process medium is not harmful to health, a finger can also be held in the
medium. When doing so, immerse the sensor several times and remove it again!
• Check the switching state of the measuring circuit!
