System configuration and installation specifications

3.1 Core Configuration Principles

Transmission window: SLG generates induced alternating field, MDS needs to be within the effective field strength range (Sg is the limit distance), and dynamic transmission needs to meet the transmission cycle

T V ≥ t K (t K is the communication time)

Metal influence: Metal will reduce the transmission window, and a metal free area (minimum 10-80 mm from the edge of MDS/SLG to the metal) needs to be reserved, which can be isolated by plastic brackets (spacing 8-20 mm)

Distance requirement:

Minimum distance between SLGs: 50 mm (SLG 40)~6000 mm (SLG 44)

Minimum distance between MDS: 50 mm (SLG 40)~4000 mm (MDS 507)

3.2 Special Configuration Instructions

MDS 507+SLG 44 (long-distance combination):

ABTAST parameter (scan interval) needs to be configured to avoid the battery running out too quickly. It is recommended t ABTAST≤1.2 sec

The transmission window is divided into a startup area (MDS ready) and a processing area (data transmission), with an angle deviation of ≤ 45 °

MDS 439E (high-temperature resistant combination):

The cyclic working temperature is ≤ 200 ° C, and the heating cooling cycle needs to be controlled (such as heating at 200 ° C for 1 hour and then cooling for>2 hours)

When the temperature is greater than 85 ° C, the transmission window parameters need to be multiplied by an offset factor C (0.7~1.05)

3.3 EMC and Grounding Standards

Shielding requirement: Both ends of the cable should be grounded, and the shielding layer should be connected to the cabinet over a large area to avoid shielding interruption

Equipotential connection: equipotential line cross-section ≥ 10 mm ², reducing interference caused by potential difference

Cabinet layout: Power components and control components are separated (spacing ≥ 10 cm), and signal lines and power lines are laid in separate slots

Interference suppression: Coil type equipment requires the addition of a freewheeling diode/RC circuit, and a filter should be installed at the power inlet

Troubleshooting and compatibility

4.1 Common fault codes (core)

Error code (hex) fault type troubleshooting direction

01 There is an error in removing MDS from the transmission window. Check the position of MDS

04 MDS memory error initializing MDS, checking battery status

06 SLG field interference increases SLG spacing, check shielded cables

0E ECC error enabled ECC driver, reinitialize MDS

80 MDS battery low voltage replacement MDS battery

4.2 Compatibility Description

Alternative models: The document provides alternative models for discontinued MDS/SLG/ASM models (as of September 2004), such as MDS 114 replaced by MDS 404 and SLG 44-ZA07 replaced by SLG 44 (6GT2 001-0DA10-0AX0)

Version compatibility: New components (such as ASM 452) are compatible with old systems and require updating the GSD file configuration
