4. HANDLING / MELSEC-A 4. HANDLING

This chapter describes the handling instructions, nomenclature, and maintenance of the PU.

4.1 Handling Instructions

(1) Do not drop or subject to shock.

(2 ) Do not disassemble the case.

(3) When the PU is not in use or the PU is connected to the CPU via a cable, f i t the protective cap on to the connector.

(4) Do not touch the connector pins of the PU.

(5j Do not open the ROM cartridge container and do not remove the ROM cartridge located inside.

4. HANDLING / MELSEC-A

(1) When designing the system, ensure that all protective and safety circuits are located outside the PC.

(2) Static electricity will damage the components on the printed circuit board therefore:

1) Ground human body and work bench. 2) Do not touch the conductive areas of the printed circuit board or the components with any

non-grounded material.

4. HANDLING / MELSEC-A 4.3 Maintenance

The PU has no special components which require inspection or replacement.

When keeping the PU in storage, take care of the following points:

( 1 ) Avoid storing the PU in the following environments:

1) Ambient temperature is outside the range -1OOC to 50C. 2) Ambient humidity i s outside the range 10 to 90%RH. 3) Condensation occurs due to sudden temperature changes. 4) Anywhere that the PU may be subjected to wind and rain or the direct rays of the sun. 5) Anywhere that there are excessive amounts of conductive powders, such as dust, dirt, and iron

filings, or corrosive gases, oil mist, salt, etc.

(2) Ensure that the audio cassette manual is fully understood before use.

The A7PU only allows the step relay (S) range t o be read. The AGGPP/AGHGP/AGPHP must be used t o set and change the step relay (SI range. The step relay (S) range is "S1536 to 2047" independently of the latch setting when step relay (S) "present" is set to the AOJ2CPU. The step relay (S) has the same functions as the internal relay (M) and can be used in the same way as the internal relay (M) in the program.
