SECTION 3
CONFIGURATION
WARNING
Set up unit for facility power (115 or 220 Vac) prior
to connecting to facility power.
After the 921A has been set up as described in section 2, it is ready for
power.
3.1 TURN-ON
The power ON-OFF switch is located on the back panel as part of the power
module (C-Figure 1.1). Place this switch in the ON position. The green
POWER indicator should illuminate and all other indicators should remain off.
If the POWER indicator does not illuminate, see section 6 Troubleshooting.
3.2 SELF-TEST
Upon application of power, the 921A performs a series of self-tests to verify
that it is functioning properly. If any of the self-tests fail, see section 6
Troubleshooting. The message PERFORMING SYSTEM SELF TEST
TESTING CHECKSUM will appear on the operator's display.
Areas tested during self-test include: CHECKSUM, CPU RAM, RAM 1, RAM
2, and RAM 3. The name of each of these areas is displayed as it is tested.
During the self-test routine, either a message is briefly displayed stating that
an area has passed, or the self-test routine stops and a message is displayed
stating what area has failed. If a failure occurs, the 921A will not allow further
operation. The reason for failure must be corrected before continuing (See
Appendix A).
After a successful self-test, the CAL indicator will illuminate indicating that the
station has automatically entered the Calibration mode. When the 921A is
turned on, it has no reference for measurement and must perform a
calibration cycle as discussed in paragraph 4.1 to establish measurement
references.
If the display indicates a mismatch, the system setup and device are not
compatible with the stored configuration. (See Appendix A)
