of two years from date of sale to our customer.
Symptom
Possible Cause
Solution
False triggering
Electrical disturbances
Damaged probe cable
Moisture in probe cable
Movement in the probe’s
environment
Dirty or noisy power supply
Lightning
1.
Disconnect from operator power supply,
temporarily connect the red and black wires
to a 9 or 12V battery. Wait 5 minutes for the
system to stabilize. If the false triggering
stops, consider using a separate power supply
for the CS202 such as a 120 VAC to
12 VDC power converter (min. 100 ma).
2.
Disconnect the relay wires and see if the false
triggering continues. If the false triggering
stops, switch the brown and green wires in the
operator and/or add earth ground connection
to COM input in operator. Verify that the
earth ground is connected securely. If the
connection is not secure, reconnect the earth
ground and retest the system.
3.
Inspect the area around the probe to see if
any ferrous metal objects may be subject to
any movement. These may include fences,
flagpoles, signs, etc. Other possible causes are
electrical power lines, electric motors, invisible
dog fences, low voltage lighting and
high-power lighting.
No detection
Minimum 5 mph
Bad wire connection
Faulty power connection
Failed relay
1.
Disconnect the output contacts from the
operator.
2.
Connect a digital multi-meter, set to read
ohms, to the CS202 internal relay COM and
NO contacts. The meter should read open
(infinity). Move a metal tool over the length of
the probe. Verify that the meter reads less
than 10 ohms. If the meter reads more than
10 ohms, the CS202 is defective.
3. Check the supply voltage using a digital
multimeter. Verify the voltage is 9-41 VDC or
6-29 VAC.
If voltage is present and there is still
no detection, the CS202 is defective.
