CHAPTER 5. TEST FUNCTION
1. General
1) This diagnostic program has been developed for diagnosing ma-
chine functions in the field. The program is contained within the
ER-A460/A470.
The diagnostic program is stored in the external ROM which will
be executed by the CPU (H8/510) which requires the following
diagnostic operations:
ER-A460/A470.
The diagnostic program is stored in the external ROM which will
be executed by the CPU (H8/510) which requires the following
diagnostic operations:
a) Proper power supply voltages are mandatory for logic circuits
(+5V, VRAM, VCKDC, POFF, +24V).
b) CPU input/output pins, CPU internal logic, CKDC6, MPCA6,
address decoder, address bus, data bus, and common
ROM/RAM must be working properly.
ROM/RAM must be working properly.
2. Operational procedure
To start the diagnostic program, you must enter the following com-
mand.

The key assignment must be properly set and the ROM and RAM
must be operating properly to go into this mode. This is necessary
because the control jumps to the program area in the SRV mode. A
master reset must be performed before operating the ECR for the first
time. After any option is installed, a program reset is required. When
the master reset or program reset is performed, be sure to check the
printout on the journal paper.

Details of test
Keyboard check is performed with the sum check data of key
code.
For sum check data, data are inputted to the upper four digits
before the diagnostics code. The data are compared with the
added data which are added until the final key (CA/AT) is pressed.
If the data agree with the added data, the end print is made. If not,
the error print is made.
