3.4.2 Adjusting the Volume

1) Apply the power after the CPU module and the A/T module are set to the following conditions.

. Set the key switch of the CPU module to ‘STOP’.

. Set the operation mode selection switch of the A/T module to ‘SET’.

2) Select the numbers of the analog timers (T00 toT15) whose timer time will be adjusted by the timer

number selection switch.

[Example] When selecting the analog timer T03

REMARK

If set the timer number selection switch of the G4F – AT3A to ‘8 to F’, nothing will be processed.

3) Set the adjustment volume to the timer time, which will be used as a goal, within the timer time range set

in the selection 3.4.1.

4) Set the operation mode selection switch to “TEST’ and check the time from turning-on of the timer

operation indication LED to turn-on of the timer contact indication LED.

5) After checking the on time of the timer contact indication LED, set the operation mode selection switch to

‘SET’.

6) To micro-adjust the timer time to the goal time, repeat 3) to 5).

7) Set the timer time for each analog timer as the procedure shown by 2) to 6).

8) After every timer time for every analog timer has been set, Set the operation mode selection switch to

‘RUN’ and execute the user program.

9) To backup the timer time set, set the operation mode selection switch to ‘TEST’. Then, the setting time

will be stored to the memory.

REMARK

If an analog timer has been adjusted during the RUN state of the CPU module, the analog timer starts its operation by the prior one of the start signals by the operation mode selection switch of the A/T module and by the user program.

Chapter 4. INSTALLATION 4.1 Installation

4.1.1 Installation Ambience

This module has high reliability regardless of its installation ambience. But be sure to check the

following for system in higher reliability and stability.

1) Ambience Requirements

Avoid installing this module in locations, which are subjected or exposed to:

- Water leakage and dust a large amount of dust, powder and other conductive power, oil mist,

salt, of organic solvent exists.

- Mechanical vibrations of impacts are transmitted directly to the module body.

- Direct sunlight. - Dew condensation due to sudden temperature change.

- High or low temperatures (outside the range of 0-55℃)

2) Installing and Wiring

- During wiring or other work, do not allow any wire scraps to enter into it.

- Install it on locations that are convenient for operation. - Make sure that it is not located near high voltage equipment on the same panel.

- Make sure that the distance from the walls of duct and external equipment be 50 mm or more.

- Be sure to be grounded to locations that have good noise immunity.

4.1.2 Handling Precautions

From unpacking to installation, be sure to check the following:

1) Do not drop it off, and make sure that strong impacts should not be applied.

2) Do not dismount printed circuit boards from the case. It can cause malfunctions.

3) During wiring, be sure to check any foreign matter like wire scraps should not enter into the upper side of the PLC, and in the event that foreign matter entered into it, always eliminate it.
