SAMCON ExCam miniTube Ultra Compact and Robust Analog Camera User Manual

SAMCON ExCam miniTube Ultra Compact and Robust Analog Camera

Introduction

The ExCam miniTube is an ultra compact and robust analog camera (type T08) which is manufactured by SAMCON Prozessleittechnik GmbH and can be used very flexibly for various applications. The main application is the usage within the hazardous areas of the chemical and/or petro-chemical industry, at offshore plants, and at biogas plants. The ExCam® miniTube is a static camera system with a fixed lens.

The camera is suitable for the usage within the Ex zones 1, 2, 21, and 22 including the gas group IIC (all gases, steams, and fogs including acetylene, hydrogen, and carbon disulphide) and the dust group IIIC (conductive dusts and flammable fibrous material). Besides for fixed installation, the T08 ExCam series is also certified to be used for mobile applications (hand-held etc.DIN EN 60079: 0 2012). Due to the usage of high-quality PTFE sealings, not only the protection level IP68 is met but also the chemical resistance is maximized.

Safety guidelines

Please observe the national regulations regarding security and accident prevention and the safety guidelines given below in this user manual!

• Attention! Cameras of the type ExCam T08 Series are not suitable for the use in zone 0 and zone 20. The temperature class and explosion group as stated on the type plate has to be observed. Alterations are not permitted. The camera is to be operated in sound conditions and in the intended way.
• Attention! Only original parts of SAMCON Prozessleittechnik GmbH may be used for repairs. Repairs concerning the explosion protection may only be carried out in accordance with the nationally applied regulations and by SAMCON Prozessleittechnik GmbH.
• Attention! External heat and/ or cooling sources are to be taken into account during the setting up. The permissible temperature range for transportation, storage, and operation of the camera has to be observed
• Attention! The instructions stated on the type and instruction plates have to be observed:

WARNING – DO NOT OPEN IN POTENTIALLY EXPLOSIVE ATMOSPHERES “

The use in hazardous areas with regard to temperature and dust layers is defined in the respective national regulations.

Prior to the first use, you should test the camera corresponding to the instructions given in the chapter commissioning.

Commissioning

For the camera’s installation and operation, the relevant national regulations, as well as the generally accepted rules of technology shall prevail. Before mounting the camera, thoroughly check it for any transportation damages, especially at the housing and cable. Installation, electrical connection, and the first commissioning must only be carried out by qualified personnel.

• Attention! Please observe the national regulations regarding security, installation, and accident prevention (e.g. DIN EN 60079-14) and the safety guidelines described in the user and in the EX installation manual!
• Attention! Please observe the installation and commissioning advices described in the ATEX/ IECEx Ex-installation manual!

Step 1: Installation

Install the ExCam® miniTube at the desired location. Mounting options and conditions, accessories, as well as safety guidelines are described in the EX installation manual of the T08 ExCam® Series.

• Attention! Prior to the camera installation, take external sources of heat or cold into account! Observe the permissible temperature range!

Step 2: Electrical connection

• Attention! The electrical connection of the equipment must be executed by qualified personnel only!
• Attention! It is mandatory that the housing of the ExCam® Series has to be grounded via a PE-connection!
• Attention! Please observe the national regulations regarding security, installation, and accident prevention (e.g. DIN EN 60079-14), as well as the safety guidelines described in this user manual and the EX installation manual!

The T08 ExCam® miniTube is delivered with an electrical connection. The maximum transmission distance from camera to receiver typically is 250 m (depending on electromagnetic tolerance/ EMC environment) and can be determined individually to reflect the particular customer specifications. The ExCam® miniTube is manufactured with a cable pigtail reflecting the desired cable length. Any electro-technical work inside the camera’s flameproof enclosure which is done by the user is prohibited and not required. Depending on the model option, the ending of the camera’s cable connection is either furnished with a plug or terminal block execusion.

Potential equalization

The potential equalization (earthing of the camera housing) is mandatory in order to avoid electrostatic charging and hence spark generation. The screw terminal on the housing’s rear side is intended for this purpose (q.v. figure 4.1). The profile of the potential equalization has to reflect the national grounding instructions (min. 4 mm2 ).

Connection table:

84. with washer Ø 9 mm (DIN 125A). 1.2Nm tightening torque has to be observed!

Connection and protection

Figures 4.3 and 4.4 illustrate the possible cable terminations available for the ExCam miniTube.

Via the system cable the AHD or CVBS signal is transferred. The power supply of the camera and the optional heating mode is also conducted via this cable.

Power supply & protection of the camera circuit

• Attention! Cables and wires must comply with the requirements of the IEC 60079-0/1/7 & 14.
• Attention! The supply line must have a sufficient cross-section. The cable protection must comply with national and international regulations.
• Attention! Use only terminals approved by SAMCON.

The power supply has to be done via the red (RD) as well as the black (BK) connection strand.

Connection table:

Potential| Color (IEC 60757)| Potential level| Profile| Remarks
---|---|---|---|---
L+| RD| +12 V DC| 0.75 mm²|
L-| BK| 0 V DC / GND| 0.75 mm²|

The camera’s typical power consumption is 1.2 Watt. The dimensioning of the equipment or the supply protection depends on:

• The selected power supply
• The cable length
• The national regulations

The following safety recommendations may serve as a basis:

Supplied power| Length system cable| Recommended protection| Comments
---|---|---|---
12.3 V DC| < 100 m| 500 mA – mT| In case the transmission range exceeds 100 m and it is intended to supply the cam- era with 12.3 V DC, please make sure to use an adjustable power supply in order to

compensate voltage drops

13 V DC| 100 m – 250 m| 500 mA – mT| In case the transmission range exceeds 100 m and it is intended to supply the cam- era with 13 V DC, please make sure to use an adjustable power supply in order to com-

pensate voltage drops

The release current of the protection has to be less than the maximum short- circuit current of the power supply (switch-mode power supply)!

Video picture connection (CVBS or AHD) Depending on the model key, the video signal of the ExCam® miniTube is either provided with wire-end (K-option) or with a BNC connector (P-option). The video signal is only to be connected to a monitor, a video matrix, or a video server. The video output is always 16:9. For systems with a resolution at 4:3, a video converter (see chapter 5) is needed.

Maintenance / Servicing / Alterations

The national regulations concerning the maintenance and servicing of electrical devices within hazardous areas are to be observed. The required maintenance intervals are specific to the individual devices. The operating company has to determine these intervals depending on the application parameters. During maintenance, focus has to be put on checking parts concerning the ignition protection category such as the integrity of the housing, the sealings and the cable glands. If maintenance measures are necessary they have to be initiated and/or executed.

Repairs and Maintenance

Repairs must only be carried out with original parts of SAMCON Prozessleittechnik GmbH. Damaged pressure-resistant housings have to be replaced completely. If in doubt, return the applicable part to SAMCON Prozessleittechnik GmbH. Repairs concerning the explosion protection must only be carried out by SAMCON Prozessleittechnik GmbH or a qualified electrical technician authorized by SAMCON Prozessleittechnik GmbH in accordance with nationally applied regulations. Rebuilding of or alterations to the devices are not permitted.

Disposal / Recycling When disposing of the device, nationally applicable regulations must be observed. This document is subject to alterations and additions.
