9.1.1 COMMUNICATIONS I/F ABNORMAL
<ERROR DESCRIPTION
>
THE Processor PCB did not communicate properly with the MULTI2 PCB during the power on
initialization of the System.
<CHECK ITEM>
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
<ERROR DESCRIPTION
>
THE Processor PCB did not communicate properly with the keypad during System power up.
<CHECK ITEM>
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
<ERROR DESCRIPTION
>
This type of failure will occur when the System's physical configuration is not compatible with
the CMOS configuration.
<CHECK ITEM>
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)
