TABLE OF CONTENTS

FOR STAND-ALONE MODE

Note

Two modes of operation are made available for the SX-2000CI and SX-2000CO: Normal mode where the unit operates within the SX-2000 system and Stand-alone mode where the unit operates independently of the SX-2000 system. This book provides instruction when the SX-2000CI and SX-2000CO are used in stand-alone mode. When using them in normal operation mode, refer to the instruction manual enclosed with the SX-2000SM System Manager of the SX-2000 series.

When Installing the Unit

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.

• Since the unit is designed for in-door use, do not install it outdoors. If installed outdoors, the aging of parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of electric shock.

When the Unit is in Use

• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.

· If you detect smoke or a strange smell coming

from the unit.

· If water or any metallic object gets into the unit

· If the unit falls, or the unit case breaks

· If it is malfunctioning (no tone sounds.)

• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to qualified service personnel.

• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.

When Installing the Unit

• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

• SX-2000CI and SX-2000CO are designed exclusively to be mounted in an equipment rack. Be sure to follow the instructions below when rackmounting the unit. Failure to do so may cause a fire or personal injury.

· Install the equipment rack on a stable, hard floor.

Fix it with anchor bolts or take other arrangements to prevent it from falling down.

· When connecting the power cord of the DC

power supply panel for the SX-2000CI/CO to an AC outlet, ensure that the total load current never exceeds the AC outlet’s allowable current capacity.

· The supplied rack-mounting screws can be used

for the TOA equipment rack only. Do not use them for other racks.

When the Unit is in Use

• Use the specified DC power supply unit AD-011 or AD-031B for the unit. Note that the use of other DC power supply unit may cause a fire.

1. SAFETY PRECAUTIONS

• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.

• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.

• After reading, keep this manual handy for future reference.

2. GENERAL DESCRIPTION

The SX-2000CI Control Input Unit is equipped with 32 control input channels, and the SX-2000CO Control Output Unit with 32 control output channels, allowing various operations to be performed by connecting external equipment. One each of the SX-2000CI and SX-2000CO must be used in combination. Connecting the CI/CO link data terminals of each unit to one another permits the contact data of multiple channels to be transmitted to the remote locations with simple wiring. The front-mounted indicators of each unit show the control input status or control output status. The SX-2000CI and SX-2000CO are 1U-size* units that can be mounted in an EIA equipment rack. It has 2 power supply inputs, one of which can be connected to a backup power source to protect against power failures. The SX-2000CI has a function to supply a stabilized 24 V DC. Priority control of the control input can be performed by making settings at the SX-2000CI.

*1U size = 44.5 mm (standard size)

10. Functional Earth Terminal [SIGNAL GND]

Hum noise may be generated when external equipment is connected to the unit. Connecting this terminal to the functional earth terminal of the external equipment may reduce the hum noise.

Note: This terminal is not for protective earth.

11. DC Power Input Terminal [DC POWER IN]

Connect an optional AD-011 or AD-031B DC Power Supply Panel to this terminal. Select the appropriate panel taking into consideration the total current consumption of all equipment to be connected to the power supply unit. (See p. 10.) When not using a redundant power system*, connect the [+] terminal of input A to the [+] terminal of input B, and the [–] terminal of input A to the [–] terminal of input B. (See p. 11 and p. 13.)

* A method of connecting separate power

sources to each power input or connecting the commercial power supply and backup power supply separately to each power input to prevent the system from going down when a cable is broken or power fails.

12. 24 V DC Output Terminal [DC 24 V OUT]

This terminal supplies 24 V DC, max. 100 mA to connected external equipment.

13. Control Input Terminals [CONTROL INPUT 1 – 32]

Photo coupler inputs. A current of approximately 2 mA flows when shorted, and the voltage becomes approximately 24 V DC when opened. Activating the control input terminal causes the control output terminal with the same channel number (SX-2000CO) to close (provides make contact).
