LED Status Indicators
12V power is indicated by a Green LED with a Power symbol next to it.
A Red LED with ON next to it indicates the switch contact status.
Connections ‘CO’ and
‘NO’ are closed when the LED is on.
Backup Battery
A CR2032 lithium coin cell is used as a backup battery. This battery will be used up by
leaving the time clock unpowered and is easily replaced by prying its holder out using the
screwdriver slots at the rear. Failure symptoms are the display going very dim or blank
when 12V is removed, also the timer may reset back to 2004 during a 12V failure.
