Cautions for Safe Operation

Power Supply

LS921P-B/ LS921N-B/ LS923P-B, LS923N-B:

This camera must always be operated a AC 24 V or DC 12 V Certified/Listed, class 2 power supply only.

LS921P-C/ LS923P-C:

This camera must always be operated a AC 230 V.

Note:

Be careful of AC frequency when the camera is operated with Line lock mode.

Handling of the unit

Be careful not to spill water or other liquids on the unit. Be cautions not to get combustible or metallic material inside the body. If used with foreign matter inside, the camera is liable to fail or to get cause of fire or electric shock.

• Remove dust or dirt on the surface of the lens with a blower.
  • Use a dry soft cloth to clean the body. If it is very dirty,

use a cloth dampened with a small quantity of neutral detergent then wipe dry.

• Avoid the use of volatile solvents such as thinners, alcohol, benzene and insecticides.
  They may damage the surface finish and/or impair the operation of the camera.

Operating and storage location

Avoid viewing a very bright object (such as light fittings) during an extended period. Avoid operating or storing the unit in the following locations.

• Extremely hot or cold places (operating temperature -10 °C to 50 °C, however, we recommend that the unit be used within a temperature range of 0 °C to 45 °C)
• Damp or dust place
• Places exposed to rain
  • Places subject to strong vibration
• Close to generators of powerful electromagnetic radiation such as radio or TV transmitters.

Concerning Auto-Iris Lenses

DC type auto-iris lens

A lens without driver circuit that operates only on a DC power source. In general, this type of lens is referred to as DC type coil lens. (Set the ALC Lens Setting Switch to the DC position.)

CAUTION:

Depending on the type of lens used, the lens may not perform properly.

DC ELC VIDEO

ELC type auto-iris lens

Use a manual or fixed iris lens (Set the ALC Lens Setting Switch to the ELC position.)

DC ELC VIDEO

VIDEO type auto-iris lens

A lens with amplifier circuit that operates on video signal and DC power source. In general, this type of lens is referred to as EE amplifier type lens. ALC and LEVEL volume level controls are available on the lens for iris adjustments. (Set the ALC Lens Setting Switch to the VIDEO position.)

CAUTION:

Be cautions not to use Auto Iris Lens with over 35 mA.

Connections

DC ELC VIDEO

Flange-back Adjustment

The adjustment is required only when a lens without focus-adjusting mechanism is mounted, or when a lens with adjusting mechanism is mounted and focus that is more accurate is needed.

1. Loosen the flange-back fixing lever.
2. Up and down the flange-back adjusting lever to obtain a focused point while watching the monitor screen.
3. Tighten the flange-back fixing lever.

Note:

The object may be out of focus when using a source of near-infrared light than using the visible light.

Mounting the camera

The mounting bracket can be secured on either the top or bottom of the camera. Use the same set of screws to attach the mounting bracket on the camera.

Note:

If using a camera mounting bracket, select a location that is strong enough to bear the full weight of the camera and the mounting bracket for long periods, and install the camera and mounting bracket securely.

*C.S. = Check Sum

• The data of total 6 bytes is transmitted from the external RS-485 device to the camera.

ex) In case of transmission, 0xC5, 0x5F, 0x02, 0x00, 0x0A"

$$ C. S. = 0 x C 5 + 0 x 5 F + 0 x 0 2 + 0 x 0 0 + 0 x 0 A = 0 x 0 1 3 0 $$
