ThyssenKrupp Communication Board MF3-C – Setup, Integration & Replacement Guide

Nanjing Zhuye Elevator Parts – OEM stock, global shipping, 24/7 support
The MF3-C is the high-speed communication backbone of every ThyssenKrupp ISIS, GL1 and GL2 controller shipped since 2016. Mounted on the main rack, this 3.3 Vdc multi-layer board bridges the 32-bit CPU to field buses (CAN, RS-485, Ethernet), drives the car-top I/O and still logs 90 days of event data to an on-board SD card. A single brown-out on the 24 V rail or a cracked CAN transceiver will throw a “7x” fault and shut the entire group down. Nanjing Zhuye Elevator Parts keeps hundreds of factory-flashed MF3-C boards in Rotterdam and Nanjing so you can restore full traffic the same day. Below is an 800-word field manual that explains correct usage, on-site programming and the replacement cycle that keeps your elevators talking, tracking and code-compliant.
1. What the MF3-C does
-
Dual CAN channels (Isis-CAN & Car-CAN) at 1 Mbit/s with 120 Ω termination
-
100 MHz ARM Cortex-M4, 512 kB SRAM, 2 MB flash for firmware & logs
-
2 × RS-485 for COP, LOP and weight sensor loops
-
10/100 Ethernet for Thyssen remote portal (TREMO) and cloud analytics
-
UL/CE listed to EN 81-20/50 and CSA B44.1 for 15-year design life
2. Tools to carry
-
MF3-C board (Nanjing Zhuye part #TK-COM-MF3-C-VE) in anti-static bag
-
2 mm & 3 mm flat screwdrivers, TX10 Torx
-
Thyssen ThyssenVUE Service Tool (TVST) laptop with MF3 plug-in licence
-
RJ-45 and USB-to-CAN adapters (shielded)
-
Multi-meter with min/max capture
-
Lock-out / tag-out kit
3. Installation – 20 minutes if you export first
Safety: place all cars on group inspection, open the main disconnect and verify 0 V on the 24 Vdc rail.
-
Photograph every connector – note X1 (24 V), X2 (Isis-CAN), X3 (Car-CAN), X4 (Eth), X5 (RS-485).
-
Remove four TX10 screws; slide the old board out of the card guides.
-
Transfer the micro-SD card (firmware + event log) and the CR2032 battery.
-
Insert the new MF3-C; torque screws to 1.0 N·m.
-
Re-connect all plugs; tug-test each one.
-
Apply power – STATUS LED blinks green 3 times then solid; ETH LED flashes during DHCP.
-
Launch TVST → Communication → Parameter Upload; select the XML back-up created earlier.
-
Run SIL-2 safety verification – must show 100 % pass.
-
Remove inspection, run 5 full-speed cycles and log the serial number in CMMS.
4. Functional test – prove it to the inspector
a) CAN-A/B differential voltage: 2.3 V dominant, 0 V recessive ±0.2 V.
b) Ethernet ping to TREMO gateway: <50 ms, 0 % loss.
c) RS-485 loop current: 20 mA ±2 mA at 19.2 kbit/s.
d) Battery voltage: 3.0 V ±0.1 V; low-battery LED off.
e) Export TVST report and attach PDF to site file.
b) Ethernet ping to TREMO gateway: <50 ms, 0 % loss.
c) RS-485 loop current: 20 mA ±2 mA at 19.2 kbit/s.
d) Battery voltage: 3.0 V ±0.1 V; low-battery LED off.
e) Export TVST report and attach PDF to site file.
5. Preventive maintenance schedule
-
Monthly – visual sweep for swollen capacitors or loose Ethernet jack.
-
Quarterly – measure 24 Vdc ripple (<50 mV) and case temperature (<55 °C).
-
Annually – export event log; clear buffers after review.
-
Every two years – replace CR2032 battery and apply latest cybersecurity patch via TVST.
6. Replacement cycle – environment decides
ThyssenKrupp baseline: 15 years. Nanjing Zhuye analytics refine this:
-
Light duty (<150 starts/day, HVAC room): 18 years
-
Standard duty (150–400 starts, residential): 15 years
-
Heavy duty (>400 starts, hospital, mall): 12 years
-
High ambient (>45 °C, rooftop cabinet): 10 years – capacitor life halves every 10 °C rise.
Replace immediately if:
-
STATUS LED red double-blink – dual CAN failure
-
Ethernet port unresponsive – lightning-damaged PHY
-
RTC loses time <24 h – battery leakage corroding pads
-
Fault buffer shows “NVRAM error” – flash wear-out after 100 k writes
7. Eco-disposal & warranty
Return the old board in the prepaid anti-static box; Nanjing Zhuye recovers gold, copper and aluminium and issues a €15 recycling credit. Every MF3-C ships with a 24-month replacement warranty, extendable to 60 months when you join our annual battery-and-patch program.
8. Why buy from Nanjing Zhuye Elevator Parts
-
380 units in stock, Rotterdam & Nanjing, flashed with latest cybersecurity firmware
-
Factory-sealed ThyssenKrupp packaging with hologram and serial database – no grey-market clones
-
QR code on box links to parameter template and 5-minute swap video
-
24/7 technical hotline staffed by ex-Thyssen commissioning engineers
-
