Indications of an operating system with a started application:
•
Analog inputs
A/D conversion in progress, LED C flashes (not all board types).
•
Analog outputs
Output signals are produced by the executing PC program.
•

The battery is mounted inside the cabinet on the right-hand side.
When the controller is started, connect the battery. Disconnectible connectors are found close to
the battery unit.
You know that the battery backup is functioning when you see the following indications:
•
On the Backup Power Supply SB510/SB511 front
–
by green LED IP indicating mains supply available and converter in operation.
–
by switch-off of the red LEDs F (Fault) and BF (Battery Fault).
Low ambient temperature may delay the switch off a few minutes.
–
the LED FC is turned on during some 10 hours, indicating fast charging.
•
On the Processor Module PM511 front
–
the green LED BC is turned on.
When you plan to disconnect power for a period of time exceeding four hours (two hours when
redundant processor modules are used), disconnect the battery. This avoids total discharge of the
battery.
Use the disconnectible contacts on the battery unit.
