1. INTRODUCTION
This manual forms part of the Installation Manual for
TOA INTERCOM SYSTEM EXES-5000.
You may add the CPU-52A to your TOA INTERCOM
SYSTEM EXES-5000, according to your specific needs, to
obtain various other functions. Correct operation of these
additional functions are not available by only connection
of the additional equipments/devices.
Provision of such additional functions requires the
followings:
(1) connection of the additional equipment, as required,
(2) selection of functions which satisfy your needs and
setting up these functions in the respective equipment.
For (1) Connections of Equipment, etc., refer to Manual
of Installation Hand Book of. Model EX-510/520 EX-
CHANGE.
This "Installation Hand Book of CPU-52A" deals prin-
cipally with (2) selection of functions and setting up of
respective equipment.
There are certain minimum installation requirements to
be met even though you may not need many additional
functions or additional equipment, it is still necessary to
read "4. Initial CPU-52A Set Up" Page 5. When you may
use only some of the additional functions or equipments,
it is not necessary to read instructions on unrequired
functions. Make sure, however, that careful study of the
necessary parts of this booklet should be done before
proceeding further.

6. Even if you do not need programming functions, be
sure to carry out initial programming and registration
at station No. 200 when you install the new unit.
Otherwise, some other functions may not work
properly.
7. The Ni-Cd battery GB50-3FA1 is capable of saving im-
portant memory registration data even at times of
power failure and we suggest you replace it at least
every 4 years.
8. When shipping the CPU-52A unit independently, place
the mini-jumper for battery back-up in off position.
Then cover CPU back with cardboard, wrap connector
section in aluminium foil and put it in a conductive
bag.
3. PRECAUTIONS FOR INSTALLATION OF CPU-52A
Please read following instructions carefully to ensure proper operation of the CPU-52A.
1. Be careful about damage by static electricity as the
CPU-52A incorporates CMOS IC's. Do not touch com-
ponents and connectors.
2. Turn off the AC power switch when you take out or
insert the CPU-52A unit, or any other unit.
3. Always insert the CPU-52A unit into the "CPU" slot.
Otherwise, there is a danger that the unit will be
damaged.
4. Make sure mini-jumper for battery back-up is always
placed in ON position each time it is used.
5. Incorrect setting of function select switches may lead
to incorrect performance.

These switches select functions.
LINKSELECTION, PAGING AMP. REMOTE
"RUN" INDICATION
Shows the CPU is working normally.
"SELF RESTART" INDICATION
Lights if the CPU self-restarts.
PROGRAM SWITCH for #200 Programming
Set this "ON" position only at time of initial program-
ing of the exchange and registration of functions. In this
case, station No. 200 is "programming station" but be-
comes a normal station when switch is placed in "OFF
position.

INITIAL CPU-52A SET UP
Make sure that you have turned off the AC power switch.
Connect the exchange, terminal board and stations.
Remove CPU-52A from the exchange.
Set mini-jumper (JP1) for battery from OFF to ON position.
Set function selection switches (SW-A ~ SW-C) for required functions.
Insert the CPU-52A into the exchange.
Put all 4 link select switches of the HCU unit upward. (Link No. 15)
Switch on the exchange.
Look at indication of LINE ADDRESS of HCU (14 LEDs) and SIGNAL CODE indication (4 LEDs)
All LED lamps are out
Memory is normal
SIGNAL CODE indication Some errors in memory
Lighted lamps of LINE ADDRESS
LEDs indicate erroneousMEMORY
ICs. See Section 5 (Page 6).
Place program switch on front panel of the CPU "ON".
Dial operation from station No. 200.
Initial programming of the exchange
Dial the following:
Dial tone will be heard. (Station No. 200 becomes a programming station)
Confirmation tone will be heard.
(Clears functions of secretary transfer)
Confirmation tone will be heard.
(Clears functions of master/sub station)
Confirmation tone will be heard.
(Clears functions of executive priority)
Confirmation tone will be heard
(Clears personal numbers and Single
Digit
Dial
numbers)
Program necessary functions (Refer to separate instructions for each function)
Remark: If there is any error in CMOS memory, you hear calling tones instead of confirmation tone.
Place program switch on front panel of the CPU in "OFF" position.
Dial operation from station No. 200.
(Station No. 200 becomes a normal station.)

Example
No. 0 and No.1
ROMs (2716) have "READ"
error.
No. 0 and No.1
N MOS-RAMS (2114)
have "READ" error.
(One set of RAMs consist of
2 ICs.)
Indicate memory error.
LINK SELECT Switch set to select No. 15
Error ROM • RAM Chip No.

5-2 Check of CMOS-RAM (Programmed data memory)
At the time of initial programming and registration using station No. 200,
1. You hear calling tone instead of confirmation tone, if there is CMOS memory error when registering single
digit number or personal number.
2. Indication on front panel of the CPU.
"RUN" LED indicator
When the system is working normally, LED is "on".
Check its condition when the system fails to work normally.
"SELF RESTART" LED indicator
This does not light when the system is working normally. Even if the high noise from the outside of the exchange
causes the CPU to work abnormally, the CPU "self-restarts" and the system keeps on working normally. Once
the CPU "self-restarts", the LED indicator is on, but it does not affect system. If you again cycle the AC power
source, the LED indicator is turned off.
5. CHECKING AND TESTING
5-1 Check of ROM & NMOS-RAM — No calls on the system.
1. Put the 4 "LINK SELECT" switches of the HCU 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 communications.

5-3 Dial receiving test
If you place all "LINK SELECT" switches (1 ~ 4) of SW-A on the CPU-52A 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.

5-4 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 time of Dl P switch installation and No.200 Programming since such mistake may lead
to trouble later.
2. Be sure to make "No. 200 Programming" after "Function Registration List" (attached to this manual) is filled
out. Keep the finished "Function Registration List" (Initial Checking Sheet for the System (133-21-023-7) as a
part of complete drawings for each installation.
