CAUSE SOLUTION
No power supply
Check for voltage at the ends of terminals 16 and 17 on
the interface unit terminal board.
"POWER" LED OFF
Resettable fuse open Wait several minutes with the interface powered down.
Transmitter – antenna outside transmission range Make sure that during probe movements the green
""tuning"" LED on the receiver remains lit.
Transmitter battery completely flat or missing Change the battery
Transmission time elapsed Give a start signal to reactivate the system.
No electrical connection between antenna and
interface
Check the receiver cable and the relative connections
to the interface.
"ERROR" LED ON
Electrical or electromagnetic interference
Move the cable from the antenna away from any power
cables. Change the operating channel.
No electrical connection between probe and
transmitter.
Check the connection between the probe and the
transmitter.
Probe damaged
"PROBE" LED:
DOES NOT CHANGE
STATUS WHEN
PROBE TOUCHES
Transmitter damaged
Remove the probe from the transmitter, connect the
sprung contacts to one another and interrupt the
contact. If despite this the LED does not change status,
the transmitter is faulty. If it changes status, the probe is
faulty.
Loose finger Check that the finger and crash protection pin (if used)
are tightened on the probe.
Loose flange Tighten all of the screws.
