Testing
Connect a net-cord to the MAINS, connect the module to the net and check if after /-6 sec. the
yellow LED 'WAIT' extinguishes; at the very same moment the LED is extinguishing, one should hear the
clack of the relais switching.
Testing the Left channel :
Connect the point PA of the left channel to the point -V (figure 1.0); the red LED 'ERROR' should now be
lightening together with the yellow LED 'WAIT'.
When the connection is interrupted again (figure 2.0), the red LED should extinguish and after approx. +/-
6 sec. the yellow LED as well.
Repeat this testing procedure by connecting the point PA to the point +V.
