15.7 Troubleshooting
Trouble free operation of the devices is normally guaranteed if you follow all the
notes on the selection of mounting locations for transmitters and receivers. The
following overview of potential problems may help should problems nevertheless
arise:
Transmitter is not
received
Check with EPM100
Possible cause and solution
In close proximity to the
transmitter (distance approx. 20-50
cm / 10-20 in), the EPM 100 does
not receive any transmission
telegrams.
Trigger transmission telegram, the
LED HI is unlit on the EPM.
Transmitter is not transmitting.
Check transmitter: Solar-powered
transmitter is supplied with sufficient light
as applicable (for quick function test,
briefly expose the device to daylight or
under a bright lamp).
In close proximity to the receiver
(approx. 20-50 cm / 10-20 in), the
EPM 100 does not receive any
transmission telegrams.
Trigger transmitter telegram, the
corresponding LO/HI LED is unlit on
EPM (HI for flush-mounted receiver,
LO for receiver with external
antenna).
Transmitter mounted beyond the
receiver range (or the transmitter was
removed in the meantime).
Change the mounting location for the
transmitter or receiver, or use repeater.
Comply with notes in Section 1.
In close proximity to the receiver
(approx. 20-50 cm / 10-20 in), the
EPM 100 has solid reception of the
transmitter telegram.
Trigger transmission telegram, the
LED HI is lit on the EPM.
a) Transmitter did not learn or
incorrectly learned.
Have receiver self-learn the transmitter.
b) Receiver is not receiving.
Check receiver, as needed, the receiver
antenna and cabling for antenna cable as
well.
Invalid EnOcean telegrams are
permanently received.
One of the two LO/HI LEDs is
continuously lit on EPM 100, but not
the VALID LED.
a) High-frequency disruptions in the
vicinity of the receiver.
Remove sources of interference (PC,
wireless phone, etc., at least 50 cm from
EnOcean receiver).
b) Jammer (continuous transmission).
Eliminate jammer.
