2. Low line voltage (contact utility if voltage at disconnect is low)
•
Flash Code number corresponds to a number of LED flashes, followed by a pause and then repeated
•
TRIP and ALERT LEDs flashing at same time means control circuit voltage is too low for operation.
•
Reset ALERT Flash code by removing 24VAC power from module
•
Last ALERT Flash code is displayed for 1 minute after module is powered on.
