2. Blank or incomplete display on board
A. Transformer unplugged
A. Plug transformer into uninterrupted power supply,
verify power connection is plugged into 4-prong
connection on PC board
B. No electric power at outlet
B. Repair outlet or use working outlet, should read 115V
with voltmeter at outlet. Verify power cannot be turned
off with another switch
C. Defective transformer
C. Check voltate at connection with transformer plugged
in. Should read >12 volt AC with voltmeter. Replace
transformer if inadequate voltage
D. Low battery after power outage
D. If power outage occurred and battery on board has
low voltage, the microprocessor may not recover cleanly
and display properly. Disconnect power from circuit
board and remove battery, wait 5 minutes. Reconnect
power, if displays appropriately, replace battery (lithium
CR2032). If you do not have battery at time of evalua-
tion, leave the battery out of board, only concern will
be time of day reset will be needed if power outage
occurs again. Voltage on battery should be > than 3
volts.
