ChartScan User’s Manual ChartScan - Unit Startup and ChartView Tutorial 1-5
5. Apply Power to ChartScan
ChartScan can be powered from a standard AC outlet. Use the following steps to connect power to
your unit.
1. Make sure ChartScan’s power switch is in the “0” (OFF) position.
2. Plug power cord CA-1 into ChartScan’s power connector, located on the rear panel. Plug the other
end of the cord into an appropriate receptacle.
3. Turn ChartScan’s power switch to the “1” (ON) position. The Power LED should light up.
At initial power-up ChartScan performs automatic self-tests to ensure that it is fully functional. The
rear panel LEDs indicate errors, if they occur. Possible error conditions and their corresponding
indicator light patterns are shown in the following table. Any pattern not shown is an internal error that
is not field-serviceable; in this case, contact the factory. When only the POWER and ERROR LEDs
are on, a configuration error exists as a result of the setup information in NV-RAM.
Error Condition LED Indicators
ALARM TRIGGER SCAN ERROR POWER
General Hardware Failure ON ON -Flash- ON
ROM Invalid for U22, COMM2 -Flash- ON
ROM Checksum Error for
U21 Comm1
ON -Flash- ON
ROM Checksum Error for
U22 COMM2
ON -Flash- ON
Non-Volatile RAM Error ON -Flash- ON
Dynamic RAM Error ON ON -Flash- ON
Interprocessor COM Error ON ON ON -Flash- ON
Configuration Error ON ON
If you observe a configuration error, perform an error status query (see E? in Appendix A). If you
observe any other type of error condition, make note of the error and contact your service
representative.
If no problems are found ChartScan will begin its power-up initialization. This self-test is performed
each time the unit is powered up regardless of whether power-on was caused by the power switch or the
Power-On Reset (*R) command.
During initialization, ChartScan self test performs the following steps:
• Checks for errors at power-up.
• Checks the flag in the NV-RAM to determine if it should power-up with factory default
settings or a user-defined configuration.
• Loads appropriate registers with corresponding values in NV-RAM.
• Checks a flag to see if alarms should be enabled at power-up, and if so, enables them.
• Loads channel configuration registers.
• Loads program sequencer with appropriate channel configurations.
• Resets computations processor to begin acquiring scans.
The self-test takes approximately 5 seconds to complete; after which, ChartScan is ready for normal
operation.
6. Connect Channel Signal Inputs
Connect channel inputs to your signal conditioning cards. Each signal conditioning card can support
up to 16 Channels. With use of the expansion chassis, you can have up to 8 signal conditioning cards.
Depending on the type(s) of cards used, your connections will be made via one or more of the
following: screw terminal, mini-plug, BNC, or safety jack type input connector.
