Normal
When the green LED is on steady, the voltage is within normal
range, all phase voltages are present, and the phase sequence is
correct. No action is needed.

Incorrect Phase Sequence
When the green LED alternates with both red LEDs, the branch-
circuit phase sequence is wrong, and the DRY-O-TRON® cannot
operate.
Disconnect electrical power from the branch circuit, follow all safety
procedures, and remove any two branch-circuit conductors from the
input lugs. Exchange their places and re-connect. Tighten as
appropriate. Do not change any factory-installed wires.
Following all safety procedures, re-apply electrical power. The
voltage monitor should be normal as shown above.

Phase Loss
When the green LED is flashing and both red LEDs are off, the
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.
