CL-DC2 is protected against polarity reversal. To ensure
that the logic relay works correctly, ensure that the
polarity of each terminal is correct.

On initial power up both the logic relay and the display
base module act as as a capacitor. Use a suitable device
for switching on the power supply and do not use any reed
relay contacts or proximity switches.
