PROBLEM
SOLUTION
No power to the
transmitters
The Analog Inputs are not internally powered. Power for
transmitters must be provided from an alternative source.
Typically, it is the same power supply that is providing
power to the LI90-1001.
No power from the relay
contacts
All of the relays are dry contact relays. Power for the
device the relays are switching must come from an
alternative source.
Relays stays OFF all the
time
Make sure that the Hand, OFF Auto for the relay is set
for Auto. The OFF setting will keep the relay OFF until
this setting has been changed.
