SCS-400

Installation Manual

Rev 3 P a g e | 1

1. Introduction

The SCS-400 System, designed and manufactured by Metermatic (Pty.) Ltd. South

Africa, is intended to control and monitor liquid product transports. The SCS-400 is

mounted on bulk petroleum vehicles and is designed to electronically seal all

loading/offloading and access points on the vehicle, providing a “sealed parcel delivery”

system.

The SCS-400 is housed in a combined Exd and Intrinsic safe enclosure, which has

approximate dimensions of 347mm x 226mm x 91mm. Four M10 bolts secures the SCS-

400 onto the vehicle. The SCS-400 enclosure has seven M20x1.5 gland entries, the first

three providing cable entries to the Intrinsic Safe side and four providing cable entries to

the Exd side. There is also an M16x1.5 gland entry at the top providing an entry for the

M16 Exd antenna bush assembly, when GSM connectivity is required.

2. Pre Installation

Failure to adhere to the operating conditions and considerations described

below could result in the equipment malfunctioning.

2.1. General

a) The SCS-400 enclosure must be mounted within a stainless steel cabinet for additional

protection from the elements.

b) The enclosure shall be installed so that it is not subjected to direct spray from the

vehicle’s wheels.

c) If welding is to be done on the vehicle after the SCS has been installed, then all

connections to the SCS must be isolated, and the internal battery should be

disconnected.

d) No additional holes may be drilled into any enclosure, as this will invalidate the

certification of the system.

e) No additional components may be installed in any enclosure, as this will invalidate the

certification of the system.

f) Repair of this equipment shall be carried out in accordance with the applicable code of

practice.

g) All cables that interconnect the various system components and sensors must be

securely fastened.

2.2. Exd Instructions

The following instructions apply to equipment covered by certificate number IECEx ICS

15.0026X. Referring to the FLP-100 (Exd Enclosure specifically)

Certification Number: IECEx ICS 15.0026X

Classification: Exd [ia] [ib] IIA T4 Mb Gb

Ambient temperature: -20°C to +60 deg °C

PART No. FLP-100

VOLTAGE: 24V

WATT: 7.5W

Installation Safety Instructions:

a) Manager’s site rules and guidelines to be followed to install equipment.

b) Refer to Installation drawings for the flameproof dimensions and correct wiring.

c) Inspection of the FLP-100 Enclosure (SCS-400) should be performed prior to

powering of the system.

d) The following items should be inspected, but inspection should not be limited to:

Flameproof bolted joints for missing or loose fasteners.

Flameproof joint gaps.

Flameproof compression glands, blanking plugs and certified bushings.

Check all terminations for loose connections.

e) Only qualified personnel are allowed to be installing, inspecting and maintaining

equipment.

2.3. Intrinsic Safe Instructions

The following instructions apply to equipment covered by certificate number IECEx ICS

15.00026X and IECEx ICS 15.0009X.

1. The equipment is only certified for use in ambient temperatures from -20C to +60C

and should not be used outside this range.

2. Installation shall be carried out in accordance with the applicable code of practice by

suitably trained personnel and in accordance with the Manual provided.

3. The plastic enclosures (REF-400) shall be installed so that under normal conditions of

use, maintenance and cleaning, danger of ignition due to electrostatic charges is

avoided.

4. The cleaning of the plastic enclosures should be executed with a damp cloth.

5. Repair of this equipment shall be carried out in accordance with the applicable code

of practice.

6. Programming connectors JJ1, JJ2 and JJ3 are only used during manufacturing, repair

or overhaul.

7. The BR2330 coin cell is not replaceable.

8. Only a Metermatic BBU-500 can be used in the SCS-400 system, replacement may

only take place in a Safe Area. This is not a user replaceable battery.

9. The certification of this equipment relies upon the following materials used in its

construction:

Aluminium enclosure (API-400, MAN-400, BVS-100).

Plastic enclosure (REF-400).

Type FR453 Elite Chemicals potting compound.

10. The certificate number has an ‘X’ suffix, which indicates that special conditions of

installation and use apply. Refer to Certificate 15.0026X - Special conditions of use

and Certificate 15.0009X Special Conditions of use for more information.

2.4. SCS-400

a) The installed location height of the unit should permit easy viewing of the display,

and provide convenient access to the keypad and the M16 Exd Antenna Bush

assembly located on the top of the enclosure.

b) Access for servicing the unit is through the front cover. Complete access by service

personnel for repair and removal of parts should be provided. For ease of service, the

cover must swing open more than 100°. The enclosure is hinged on the left.

c) The SCS enclosure must be earthed to the vehicle’s chassis by means of either the

connecting bolts or bonding point provided.

d) A plastic isolator separates Intrinsically Safe connections J7 and J8 from Non

Intrinsically Safe connections J1, J2, J3, J4 and J5. Care must be taken that in the

event of any connection comes loose, a clearance of at least 50mm is maintained

between IS and non-IS connections.

2.5. API-400 Sensor

a) The API adaptors must be installed so that the API-400 sensor is positioned

horizontally.

2.6. BVS-100 Sensor

a) Ensure that the correct length BVS-stem is used for the bottom valve type.

b) When attaching the BVS-100 sensor to the bottom valve ensure that the bolts are not

overtightened, as this will affect operation.

2.7. MAN-400 Sensor

a) The MAN-400 sensors must be installed on top of the manhole cover perpendicular to

the opening movement of the manhole.

b) All MAN-400 sensor cables must be routed neatly and securely to prevent any

obstruction to operators or interference with manhole operation.

c) All MAN-400 sensors must be orientated in the same direction.

2.8. REF-400 Sensor

a) The REF-400 sensor must be installed at the end of the CAN bus. (Refer to section

CANBUS Interface (Connector J9) for details).

b) The REF-400 sensor cable must be routed neatly and securely to prevent any

obstruction to operators or interference with manhole operation.

c) The REF-400 sensor must be orientated in the same direction as all the MAN-400

sensors.

It is important to supply the SCS-400 from the Isolator Switch and not

directly from the battery as shown in the figure below. Failure to do this will

invalidate the IS certification.

The SCS-400 is protected by a 5A internal fuse (F1). It is recommended to connect an

additional 3A inline fuse on the positive (+) line from the vehicle battery. Install this fuse

after the isolator switch as shown below.
