Incorrect Phase Sequence
When the green LED alternates with both red LEDs, the incoming
branch circuit phase sequence is wrong, and the DRY-O-TRON can-
not operate.
Disconnect electrical power from the branch circuit, follow all nec-
essary and proper safety procedures, and remove any two branch-
circuit conductors from the input lugs. Exchange their places and re-
connect. Tighten as appropriate.
Following all safety procedures, re-apply electrical power. The volt-
age monitor should be normal as shown above.

Phase Loss
When the green LED is flashing and with both red LEDs are off, the
incoming branch circuit does not have all three phases, and the
DRY-O-TRON cannot operate.
Have a qualified electrician fix the problem and re-apply electrical
power. The voltage monitor should be normal as shown above.

Incoming Voltage Below Minimum Allowable
When the green LED is flashing and the lower red LED is on, the
incoming voltage is too low, and the DRY-O-TRON cannot operate.
Voltages below this level will result in motor overheating. Do not
adjust the voltage monitor without explicit instructions from Dectron.
Have a qualified electrician fix the problem and re-apply electrical
power. The voltage monitor should be normal as shown above.

Incoming Voltage Above Maximum Allowable
When the green LED is flashing and the upper red LED is on, the
incoming voltage is too high, and the DRY-O-TRON cannot operate.
Voltages above this level will result in motor overheating. Do not
adjust the voltage monitor without explicit instructions from Dectron.
Have a qualified electrician fix the problem and re-apply electrical
power. The voltage monitor should be normal as shown above.
