3. TROUBLE SHOOTING

3-1 Check of ROM & NMOS-RAM - No calls on the system.

1.Put the 4 "LINK SELECT" switches of the HC upward (Link No. 15 SELECT) and switch on the AC power of the exchange.

2.If there is no error, the indication lamps will not light.

3.In the event of a memory error, the lamps may light as shown in the example of Fig. 1.

4.The error indications will remain on until you use Link No. 15 for com- munications.

3-2 Confirming of the CP normal working

If the CP, OC and HC are working normally, the HC's indication lamps of LINE BUSY, LINE ADDRESS and SIGNAL CODE go out.

When any of the lamps lies alight, it is possible that any of the CP, OC or HC is faulty.

Check first that the CLOCK lamp of the HC is lighting, then confirm that the CP is working normally by hearing the clicking sound of the PI unit's relay which is produced when the relay is activated through dial operation of the paging.

If the CP is found working normally, chances are that the HC is faulty, followed by the OC.

3-3 Check of CMOS-RAM (Programmed data memory)

You hear calling tone instead of confirmation tone, if there is CMOS memory error at the time of initial programming and registration using station No. 200, or at the time of registration to Single Digit Number or Personal Number or Remote Number.

3-4 Dial receiving test

1.Instead of the PI-62 unit, use the PIU-52A (a unit used in the EXES-5000 System) to check the dial receiving section of the CP also to check if the signal is correctly transmitted as dialed from the station to be tested.

2.If you place all "LINK SELECT" switches (1 ~ 4) of SW-A on the CP-63 in "OFF" position, conversation is impossible but the dial code from each station is indicated on the LED's of the PIU as dialed. Use this to find the cause of any fault of receiving dial information.

Error ROM • RAM Chip No.

Example

No. 1 and No. 2 out of 4 pcs ROMs (2732) have "read" error.

No. 0 and No. 1 out of 4 sets of N-MOS RAMs (2114) have "read" error.

(One set of RAMs consist of 2 ICs)

Indicate memory error.

3.With use of the PI-62 unit fitted with no LED, you can also check that the CP receives the dial signal by hearing the click sound of the relay produced when it is activated.

3-5 The order of link usage.

After power is on, links are used in numerical order for each communication.

Remember this to help you when problems are found with specific links.

Remarks:

1.Be sure to avoid mistake at the time of DIP switch installation and No. 200 Programming since such mistake may lead to trouble later.

2.Be sure to make "No. 200 Programming" after "Programming Data Table" (attached to this manual) is filled out. Keep the finished "Programming Data Table" (Initial Checking Sheet for the System 133-21-085-5) as a part of complete drawings for each installation.
