9.1 POWER ON ABNORMAL
WARNING:
DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM
COMPONENTS WITH POWER APPLIED.
Communications I/F Abnormal Keyboard Failure
CMOS Power On Self-Test (POST) Failure CRT Failure
DOS Boot Failure Failure to Fasten
9.1.1 COMMUNICATIONS I/F ABNORMAL
>
THE Processor PCB did not communicate properly with the MULTI2 PCB during the power on
initialization of the System.
1. Verify that the ISA Main Unit is not located near any strong electrical or magnetic fields.
2. Confirm that the ISA Main Unit input power remains constantly within specifications:
200~230 VAC +/- 10%, 50/60 Hz, single phase.
3. Verify that the ISA Main Unit power cable is free from damage and is properly connected.
4. Power up the System. If the Abnormal persists, then replace the entire ISA Main Unit.
(Refer to Section 8.3.1)
9.1.2 Keyboard Failure
>
THE Processor PCB did not communicate properly with the keypad during System power up.
1. Verify that the keypad cable is free from damage and is properly connected.
2. Replace the keypad with one that is known to be good.
3. Verify that the ISA Main Unit is not located near any strong electrical or magnetic fields.
4. Confirm that the ISA Main Unit input power remains constantly within specifications:
200~230 VAC +/- 10%, 50/60 Hz, single phase.
5. Verify that the ISA Main Unit power cable is free from damage and is properly connected.
6. Power up the System. If the Abnormal persists, then replace the entire ISA Main Unit.
(Refer to Section 8.3.1)
9.1.3 CMOS power on Self-test (POST) failure
>
This type of failure will occur when the System's physical configuration is not compatible with
the CMOS configuration.
1. ensure that there are no active PLC inputs during the POST.
2. ensure that the ISA Main Unit is not located near any strong electrical or magnetic fields.
3. Confirm that the ISA Main Unit input power remains constantly within specifications:
200~230 VAC +/- 10%, 50/60 Hz, single phase.
4. Verify that the ISA Main Unit power cable is free from damage and is properly connected.
5. If the problem persists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
